A Databricks Cluster is a group of virtual machines (VMs) in the cloud that work together to process data using Apache Spark.It provides the memory, CPU, and compute power required to run your code efficiently. Clusters are used for: Each cluster has two main parts: Types of Clusters Databricks supports multiple cluster types, depending on how you want to work. Cluster Type Use Case Interactive (All-Purpose) Clusters Used for notebooks, ad-hoc queries, and development. Multiple users can attach their notebooks. Job Clusters Created automatically for scheduled jobs or production pipelines. Deleted after job completion. Single Node Clusters Used for small data exploration or lightweight development. No executors, only one driver node. How Databricks Clusters WorkWhen you execute a notebook cell, Databricks sends your code to the cluster.The cluster’s driver node divides your task into smaller jobs and distributes them to the executors.The executors process the data in parallel and send the results back to the driver.This distributed processing is what makes Databricks fast and scalable for handling massive datasets. Step-by-Step: Creating Your First Cluster Let’s create a cluster in your Databricks workspace. Step 1: Navigate to Compute In the Databricks sidebar, click Compute. You’ll see a list of existing clusters or an option to create a new one. Step 2: Create a New Cluster Click Create Compute in the top-right corner. Step 3: Configure Basic Settings Step 4: Select Node Type Choose the VM type based on your workload. For development, Standard_DS3_v2 or Standard_D4ds_v5 are cost-effective. Step 5: Auto-Termination Set the cluster to terminate after 10 or 20 minutes of inactivity. This prevents unnecessary cost when the cluster is idle. Step 6: Review and Create Click Create Compute. After a few minutes, your cluster will turn green, indicating it is ready to run code. Clusters in Unity Catalog-Enabled Workspaces If Unity Catalog is enabled in your workspace, there are a few additional configurations to note. Feature Standard Workspace Unity Catalog Workspace Access Mode Default is Single User. Must choose Shared, Single User, or No Isolation Shared. Data Access Managed by workspace permissions. Controlled through Catalog, Schema, and Table permissions. Data Hierarchy Database → Table Catalog → Schema → Table Example Query SELECT * FROM sales.customers; SELECT * FROM main.sales.customers; When you create a cluster with Unity Catalog, you will see a new Access Mode field in the configuration page. Choose “Shared” if multiple users need to access governed data under Unity Catalog. Managing Cluster Performance and CostClusters can become expensive if not managed properly. Follow these tips to optimize performance and cost: a. Use Auto-Termination to shut down idle clusters automatically.b. Choose the right VM size for your workload. Avoid oversizing.c. Use Job Clusters for production pipelines since they start and stop automatically.d. Leverage Autoscaling so Databricks can adjust the number of workers dynamically.e. Monitor with Ganglia metrics to identify performance bottlenecks. Common Cluster Issues and Fixes Issue Cause Fix Cluster stuck starting VM quota exceeded or region issue Change VM size or region. Slow performance Too few workers or data skew Increase worker count or repartition data. Access denied to data Missing storage credentials Use Databricks Secrets or Unity Catalog permissions. High cost Idle clusters running Enable auto-termination. Best Practices for Using Databricks Clusters1. Always attach your notebook to the correct cluster before running it.2. Use development, staging, and production clusters separately.3. Keep the cluster runtime version consistent across environments.4. Terminate unused clusters to reduce cost.5. If you use Unity Catalog, prefer Shared clusters for collaboration. To conclude, clusters are the heart of Databricks.They provide the compute power needed to process large-scale data efficiently. Without them, Databricks Notebooks and Jobs cannot run. Once you understand how clusters work, you will find it easier to manage costs, optimize performance, and build reliable data pipelines.

Databricks Time Travel is a powerful feature of Delta Lake that allows you to access older versions of your data. Whether you want to debug issues, recover deleted records, compare historical performance, or audit how data changed over time—Time Travel makes it effortless. It’s like having a complete rewind button for your tables, eliminating the fear of accidental updates or deletes. What is Time Travel? Time Travel enables you to query previous snapshots of a Delta table using either VERSION AS OF or TIMESTAMP AS OF. Delta automatically versions every transaction-UPDATE, MERGE, DELETE, INSERT. So, you can always go back to an earlier state without restoring backups manually. This versioning is stored in the Delta Log, making rewind operations efficient and reliable. Why Time Travel Matters (Use Cases) Debugging Pipelines: Quickly check what the data looked like before a bad job ran. Accidental Deletes: Recover records or entire tables. Audit & Compliance: Easily demonstrate how data has evolved. Root Cause Analysis: Compare two versions side by side. Model Re-training: Use historical datasets to retrain ML models. Data Quality Tracking: Validate when incorrect data first appeared. How Delta Stores Versions (Architecture Overview) Delta Lake stores metadata and version history inside the _delta_log folder. Each commit creates a new JSON or checkpoint Parquet file representing table state. When you run a query using Time Travel, Databricks does not rebuild the entire table. Instead, it directly reads the snapshot based on the transaction log. This architecture makes Time Travel extremely fast and scalable—even on very large datasets. Time Travel Commands Query older data: SELECT * FROM table VERSION AS OF 5; SELECT * FROM table TIMESTAMP AS OF ‘2024-11-20T10:00:00’; A. Example: DESCRIBE HISTORY Below is an example of using DESCRIBE HISTORY on a Delta table. B. Querying a Specific Version Here is how you can fetch an older snapshot using VERSION AS OF. C. Restoring a Table You can restore a Delta table to any older version using RESTORE TABLE. Retention Rules Delta keeps older versions based on two configs: `delta.logRetentionDuration` → How long commit logs are stored. `delta.deletedFileRetentionDuration`→ How long old data files are retained. By default, Databricks keeps 30 days of history. You can increase this if your compliance policy requires longer retention. Best Practices – Use Time Travel for debugging pipeline issues. – Increase retention for sensitive or audited datasets. – Use `DESCRIBE HISTORY` frequently during development. – Avoid unnecessarily large retention windows—they increase storage costs. – Use `RESTORE` carefully in production environments. To conclude, time Travel in Databricks brings reliability, auditability, and simplicity to modern data engineering. It protects teams from accidental data loss and gives full visibility into how datasets evolve. With just a few commands, you can analyze, compare, or restore historical data instantly making it one of the most useful features of Delta Lake.

Most organizations think of Dynamics 365 Finance & Operations (D365 F&O) only as a system that receives data from other applications. In reality, the most powerful and scalable architecture is when F&O itself becomes the source of truth and an event producer. Every financial transaction, inventory update, order confirmation, or invoice posting is a critical business event – and when these events are not shared with other systems in real time, businesses face: So, the real question is: What if every critical event in D365 F&O could instantly trigger actions in other systems? The answer lies in an event-driven architecture using Azure Event Hub and Azure Logic Apps, where F&O becomes the producer of events and the rest of the enterprise becomes real-time listeners. Core Content Event-Driven Model with F&O as Source In this model, whenever a business event occurs inside Dynamics 365 F&O, an event is immediately published to Azure Event Hub. That event is then picked up by Azure Logic Apps and forwarded to downstream systems such as: In simple terms: Event occurs in F&O → Event is pushed to Event Hub → Logic App processes → External system is updated This enables true real-time integration across your entire IT ecosystem. Why Use Azure Event Hub Between F&O and Other Systems? Azure Event Hub is designed for high-throughput, real-time event ingestion. This makes it the perfect choice for capturing business transactions from F&O. Azure Event Hub provides: This ensures that every change in F&O is captured and made available in real time to any subscribed system. Technical Architecture Here is the architecture with F&O as the source: Role of each layer: Component Responsibility D365 F&O Generates business events Event Hub Ingests & streams events Logic App Consumes + transforms events External Systems Act on the event This architecture is:✔ Decoupled✔ Scalable✔ Secure✔ Real-time✔ Fault tolerant How Does D365 F&O Send Events to Event Hub? Using Business Events F&O has built-in Business Events Framework which can be configured to trigger events such as: These business events can be configured to push data to an Azure Event Hub endpoint. This is the cleanest, lowest-code, and recommended approach. Logic App as Event Consumer (Real-Time Processing) Azure Logic App is connected to Event Hub via Event Hub Trigger: Once triggered, the Logic App performs: Example downstream actions: F&O Event Logic App Action Invoice Posted Push to Power BI + Send email Sales Order Create record in CRM Inventory Change Update eCommerce stock Vendor Created Sync with procurement system This allows one F&O event to trigger multiple automated actions across platforms in real time. Real-Time Example: Invoice Posted in F&O Step-by-step flow: All of this happens automatically, within seconds. This is true enterprise-wide automation. Key Technical Benefits Why this Architecture is important for Technical Leaders If you are a CTO, architect, or technical lead, this approach helps you: Instead of systems “asking” for data, they react to real-time business events. To conclude, by making Dynamics 365 Finance & Operations the event source and combining it with Azure Event Hub and Azure Logic Apps, organizations can create a fully automated, real-time, intelligence-driven ecosystem. Your first step: ➡ Identify a critical business event in F&O➡ Publish it to Azure Event Hub➡ Use Logic App to trigger automatic actions This single change can transform your integration strategy from reactive to proactive.

Why This Story Matters to Today’s CIOs and CTOs For many large manufacturing organizations, integration platforms quietly become one of the most expensive and least visible parts of the IT landscape. Licensing renewals happen in the background, operational risks remain hidden, and innovation conversations get delayed because the digital backbone is simply not ready. This is the story of a 150-year-old global manufacturer that reached that exact inflection point and how rethinking integration architecture helped them reduce costs dramatically while laying the foundation for AI-driven decision-making. The Breaking Point: When Middleware Became a Business Risk The manufacturer had relied on traditional middleware platforms for years to connect Dynamics 365 Field Service, Finance & Operations, Sales, Shopify, and SQL-based systems. Over time, the middleware layer grew complex, opaque, and expensive. The wake-up call came during a contract renewal discussion. a. Middleware licensing had increased from $20,000 to $50,000 per year. b. A mandatory three-year commitment pushed the proposal to $160,000. c. Despite the cost, the platform still behaved like a black box failures were hard to trace, and teams often learned about issues only after business users raised concerns. For leadership, this was no longer just an IT problem. It was a structural constraint on scalability, transparency, and future AI initiatives. CloudFronts’ Perspective: Cost Is a Symptom, Not the Root Cause When CloudFronts assessed the environment, the issue was clear: the organization was paying enterprise-level licensing fees for integration workloads that ran only a handful of times per day. From an architectural standpoint, this created two forms of debt: 1. Financial debt – High fixed costs with limited flexibility 2. Technical debt – Opaque integrations with no real-time visibility or standardized transformation logic Our recommendation was not a like-for-like migration, but a fundamental shift to a cloud-native, consumption-based model using Azure Integration Services (AIS). Rebuilding the Backbone with Azure Integration Services The new architecture replaced legacy middleware and Scribe with: 1. Azure Logic Apps for orchestration 2. Azure Functions for transformation and reusable logic 3. Azure Blob Storage for configuration, templates, and checkpoints Designed for Global Complexity The manufacturer operates across multiple legal entities and regions: a. United States (TOUS) b United Kingdom (TOUK) c. India (TOIN) d. China (TOCN) Each entity has unique account number formats, compliance rules, and data behaviors. The solution introduced branching logic and region-specific mappings while maintaining a single, governed integration framework. Eliminating the Black Box: Visibility by Design One of the most impactful changes was not technical it was operational. Legacy middleware offered limited insight into what was running, failing, or slowing down. CloudFronts replaced this with first-class monitoring and observability. What Changed a Power BI dashboard built on Azure Log Analytics provide real-time visibility into integration health b. Automated alerts notify teams within one hour of failures c. Integration teams can now proactively resolve issues before they impact order-to-cash or service operations This shift alone reduced firefighting and restored confidence in the integration layer. From Cost Optimization to AI Readiness While the immediate outcome was cost reduction, the strategic impact went far beyond savings. By standardizing transformations and ensuring clean, reliable data flows, the organization created the foundation required for: a. Databricks-based analytics b. Unity Catalog for governance and lineage c. Future Generative AI use cases across operations For example, leadership can now envision scenarios where users ask: “Is raw material available for this production order?” “Which service orders are likely to breach SLA next week?” These are not AI experiments they depend entirely on trusted, unified data. As an early validation step, 32 fragmented reports were consolidated into a governed catalog, proving the readiness of the new backbone. The Integration Framework Behind the Scenes The solution follows a modular, scalable framework: a. Liquid templates (JSON-to-JSON) decouple transformations from orchestration b. Templates are stored in Azure Blob Storage, allowing updates without redeploying Logic Apps c. Incremental synchronization ensures only changed data is processed every five minutes d. This approach balances performance, maintainability, and governance critical for long-term sustainability. Results That Matter to Leadership Business and Technology Outcomes a. Annual integration cost reduced by ~95% b. Spend dropped from $50,000 to approximately $2,500–$4,000 per year c. Estimated annual savings: ~$140,000 d. Systems connected: D365 Field Service, Sales, Finance & Operations, Shopify, SQL Server e. Scalability: Designed to modernize over 600 legacy reports More importantly, integration is no longer a blocker it is an enabler. A Practical Playbook for CIOs Facing Similar Challenges 1. Start with transparency if you can’t see failures, you can’t fix them 2. Challenge fixed-cost licensing models for low-frequency workloads 3. Standardize transformations before investing in AI platforms 4. Treat integration as a product, not plumbing To conclude, for this 150-year-old manufacturer, modernization was not about replacing tools it was about reclaiming control of their digital backbone. By moving away from legacy middleware and embracing Azure Integration Services, they reduced cost, eliminated blind spots, and unlocked a clear path toward AI-driven operations. At CloudFronts, we see this pattern repeatedly. The organizations that succeed with AI are not the ones experimenting first but the ones fixing their foundations first.

As data platforms mature, teams often face a familiar question:Should we continue with classic ETL pipelines, or move to Delta Live Tables (DLT)? Both approaches work. Both are widely used. The real challenge is knowing which one fits your use case, not which one is newer or more popular. In this blog, I’ll break down Delta Live Tables vs classic ETL from a practical, project-driven perspective, focusing on how decisions are actually made in real data engineering work. Classic ETL in Databricks Classic ETL in Databricks refers to pipelines where engineers explicitly control each stage of data movement and transformation. The pipeline logic is written imperatively, meaning the engineer decides how data is read, processed, validated, and written. Architecturally, classic ETL pipelines usually follow the Medallion pattern: Each step is executed explicitly, often as independent jobs or notebooks. Dependency management, error handling, retries, and data quality checks are all implemented manually or through external orchestration tools. This approach gives teams maximum freedom. Complex ingestion logic, conditional transformations, API integrations, and custom performance tuning are easier to implement because nothing is abstracted away. However, this flexibility also means consistency and governance depend heavily on engineering discipline. We implemented a Classic ETL pipeline in our internal Unity Catalog project, migrating 30+ Power BI reports from Dataverse into Unity Catalog to enable AI/BI capabilities. This architecture allows data to be consumed in two ways – through an agentic AI interface for ad-hoc querying and through Power BI for governed, enterprise-grade visualizations. We chose the ETL approach because it provides strong data quality control, schema stability, and predictable performance at scale. It also allows us to apply centralized transformations, enforce governance standards, optimize storage formats, and ensure consistent semantic models across reporting and AI workloads -making it ideal for production-grade analytics and enterprise adoption. Delta Live Tables Delta Live Tables is a managed, declarative pipeline framework provided by Databricks. Instead of focusing on execution steps, DLT encourages engineers to define what tables should exist and what rules the data must satisfy. From an architectural perspective, DLT formalizes the Medallion pattern. Pipelines are defined as a graph of dependent tables rather than a sequence of jobs. Databricks automatically understands lineage, manages execution order, applies data quality rules, and provides built-in monitoring. DLT pipelines are particularly well-suited for transformation and curation layers, where data is shared across teams and downstream consumers expect consistent, validated datasets. The platform takes responsibility for orchestration, observability, and failure handling, reducing operational overhead. In my next blog, I will demonstrate how to implement Delta Live Tables (DLT) in a hands-on, technical way to help you clearly understand how it works in real-world scenarios. We will walk through the creation of pipelines, data ingestion, transformation logic, data quality expectations, and automated orchestration. The Core Architectural Difference The fundamental difference between classic ETL and Delta Live Tables is how responsibility is divided between the engineer and the platform. In classic ETL, the engineer owns the full lifecycle of the pipeline. This provides flexibility but increases maintenance cost and risk. In Delta Live Tables, responsibility is shared: the engineer defines structure and intent, while Databricks enforces execution, dependencies, and quality. This shift changes how pipelines are designed. Classic ETL is optimized for control and customization. Delta Live Tables is optimized for consistency, governance, and scalability. When Classic ETL Makes More Sense Classic ETL is a strong choice when pipelines require complex logic, conditional execution, or tight control over performance. It is well suited for ingestion layers, API-based data sources, and scenarios where transformations are highly customized or experimental. Teams with strong engineering maturity may also prefer classic ETL for its transparency and flexibility, especially when governance requirements are lighter. When Delta Live Tables Is the Better Fit Delta Live Tables excels when pipelines are repeatable, standardized, and shared across multiple consumers. It is particularly effective for silver and gold layers where data quality, lineage, and operational simplicity matter more than low-level control. DLT is a good architectural choice for enterprise analytics platforms, certified datasets, and environments where multiple teams rely on consistent data definitions. A Practical Architectural Pattern In real-world platforms, the most effective design is often hybrid. Classic ETL is used for ingestion and complex preprocessing, while Delta Live Tables is applied to transformation and curation layers. This approach preserves flexibility where it is needed and enforces governance where it adds the most value. To conclude, Delta Live Tables is not a replacement for classic ETL. It is an architectural evolution that addresses governance, data quality, and operational complexity. The right question is not which tool to use, but where to use each. Mature Databricks platforms succeed by combining both approaches thoughtfully, rather than forcing a single pattern everywhere. Choosing wisely here will save significant rework as your data platform grows. Need help deciding which approach fits your use case? Reach out to us at transform@cloudfronts.com

As organizations scale their analytics platforms, governance often becomes the hardest problem to solve. Data may be accurate, pipelines may run on time, and reports may look correct, but without proper governance, the platform becomes fragile. We see this pattern frequently in environments where Power BI reporting has grown around a mix of SQL Server databases, direct Dataverse connections, shared storage accounts, and manually managed permissions. Over time, access control becomes inconsistent, ownership is unclear, and even small changes introduce risk. Unity Catalog addresses this problem by introducing a centralized, consistent governance layer across Databricks and downstream analytics tools like Power BI. The Governance Problem Most Teams Face In many data platforms, governance evolves as an afterthought. Access is granted at different layers depending on urgency rather than design. Common symptoms include: As reporting expands across departments like Finance, HR, PMO, and Operations, this fragmented governance model becomes difficult to control and audit. Why Unity Catalog Changes the Governance Model Unity Catalog introduces a unified governance layer that sits above storage and compute. Instead of managing permissions at the file or database level, governance is applied directly to data assets in a structured way. At its core, Unity Catalog provides: This shifts governance from an operational task to an architectural capability. A Structured Data Hierarchy That Scales Unity Catalog organizes data into a simple, predictable hierarchy: Catalog → Schema → Table This structure brings clarity to large analytics environments. Business domains can be separated cleanly, such as CRM, Finance, HR, or Projects, while still being governed centrally. For Power BI teams, this means datasets are easier to discover, understand, and trust. There is no ambiguity about where data lives or who owns it. Centralized Access Control Without Storage Exposure One of the biggest advantages of Unity Catalog is that access is granted at the data object level, not the storage level. Instead of giving Power BI users or service principals direct access to storage accounts, permissions are granted on catalogs, schemas, or tables. This significantly reduces security risk and simplifies access management. From a governance perspective, this enables: Power BI connects only to governed datasets, not raw storage paths. Cleaner Integration with Power BI When Power BI connects to Delta tables governed by Unity Catalog, the reporting layer becomes simpler and more secure. Benefits include: This model works especially well when combined with curated Gold-layer tables designed specifically for reporting. Governance at Scale, Not Just Control Unity Catalog is not only about restricting access. It is about enabling teams to scale responsibly. By defining ownership, standardizing naming, and centralizing permissions, teams can onboard new data sources and reports without reworking governance rules each time. This is particularly valuable in environments where multiple teams build and consume analytics simultaneously. Why This Matters for Decision Makers For leaders responsible for data, analytics, or security, Unity Catalog offers a way to balance speed and control. It allows teams to move quickly without sacrificing governance. Reporting platforms become easier to manage, easier to audit, and easier to extend as the organization grows. More importantly, it reduces long-term operational risk by replacing ad-hoc permission models with a consistent governance framework. To conclude, strong governance is not about slowing teams down. It is about creating a structure that allows analytics platforms to grow safely and sustainably. Unity Catalog provides that structure for Databricks and Power BI environments. By centralizing access control, standardizing data organization, and removing the need for direct storage exposure, it enables a cleaner, more secure analytics foundation. For organizations modernizing their reporting platforms or planning large-scale analytics initiatives, Unity Catalog is not optional. It is foundational. If your Power BI and Databricks environment is becoming difficult to govern as it scales, it may be time to rethink how access, ownership, and data structure are managed. We have implemented Unity Catalog–based governance in real enterprise environments and have seen the impact it can make. If you are exploring similar initiatives or evaluating how to strengthen governance across your analytics platform, we are always open to sharing insights from real-world implementations.

When integrating Dynamics 365 with external systems, one of the first decisions you’ll face is real-time vs batch (scheduled) integration. It might sound simple, but choosing the wrong approach can lead to performance issues, unhappy users, or even data inconsistency. In this blog, I’ll Walk through the key differences, when to use each, and lessons we’ve learned from real projects across Dynamics 365 CRM and F&O. The Basics: What’s the Difference? Type Description Real-Time Data syncs immediately after an event (record created/updated, API call). Batch Data syncs periodically (every 5 mins, hourly, nightly, etc.) via schedule. Think of real-time like WhatsApp you send a message, it goes instantly. Batch is like checking your email every hour you get all updates at once. When to Use Real-Time Integration Use It When: Example: When a Sales Order is created in D365 CRM, we trigger a Logic App instantly to create the corresponding Project Contract in F&O. Key Considerations When to Use Batch Integration Use It When: Example: We batch sync Time Entries from CRM to F&O every night using Azure Logic Apps and Azure Blob checkpointing. Key Considerations Our Experience from the Field On one recent project: As a Result, the system was stable, scalable, and cost-effective. To conclude, you don’t have to pick just one. Many of our D365 projects use a hybrid model: Start by analysing your data volume, user expectations, and system limits — then pick what fits best.

If you’re new to Databricks, chances are someone told you “Everything starts with a Notebook.” They weren’t wrong. In Databricks, a Notebook is where your entire data engineering workflow begins from reading raw data, transforming it, visualizing trends, and even deploying jobs. It’s your coding lab, dashboard, and documentation space all in one. What Is a Databricks Notebook? A Databricks Notebook is an interactive environment that supports multiple programming languages such as Python, SQL, R, and Scala. Each Notebook is divided into cells you can write code, add text (Markdown), and visualize data directly within it. Unlike local scripts, Notebooks in Databricks run on distributed Spark clusters. That means even your 100 GB dataset is processed within seconds using parallel computation. So, Notebooks are more than just code editors they are collaborative data workspaces for building, testing, and documenting pipelines. How Databricks Notebooks Work Under the hood, every Notebook connects to a cluster a group of virtual machines managed by Databricks. When you run code in a cell, it’s sent to Spark running on the cluster, processed there, and results are sent back to your Notebook. This gives you the scalability of big data without worrying about servers or configurations. Setting Up Your First Cluster Before running a Notebook, you must create a cluster it’s like starting the engine of your car. Here’s how: Step-by-Step: Creating a Cluster in a Standard Databricks Workspace Once the cluster is active, you’ll see a green light next to its name now it’s ready to process your code. Creating Your First Notebook Now, let’s build your first Databricks Notebook: Your Notebook is now live ready to connect to data and start executing. Loading and Exploring Data Let’s say you have a sales dataset in Azure Blob Storage or Data Lake. You can easily read it into Databricks using Spark: df = spark.read.csv(“/mnt/data/sales_data.csv”, header=True, inferSchema=True)display(df.limit(5)) Databricks automatically recognizes your file’s schema and displays a tabular preview.Now, you can transform the data: from pyspark.sql.functions import col, sumsummary = df.groupBy(“Region”).agg(sum(“Revenue”).alias(“Total_Revenue”))display(summary) Or, switch to SQL instantly: %sqlSELECT Region, SUM(Revenue) AS Total_RevenueFROM sales_dataGROUP BY RegionORDER BY Total_Revenue DESC Visualizing DataDatabricks Notebooks include built-in charting tools.After running your SQL query:Click + → Visualization → choose Bar Chart.Assign Region to the X-axis and Total_Revenue to the Y-axis.Congratulations — you’ve just built your first mini-dashboard! Real-World Example: ETL Pipeline in a Notebook In many projects, Databricks Notebooks are used to build ETL pipelines: Each stage is often written in a separate cell, making debugging and testing easier.Once tested, you can schedule the Notebook as a Job running daily, weekly, or on demand. Best Practices To conclude, Databricks Notebooks are not just a beginner’s playground they’re the backbone of real data engineering in the cloud.They combine flexibility, scalability, and collaboration into a single workspace where ideas turn into production pipelines. If you’re starting your data journey, learning Notebooks is the best first step.They help you understand data movement, Spark transformations, and the Databricks workflow everything a data engineer need.

From AI Experiments to AI That Can Be Trusted  Generative AI has moved from experimentation to executive priority. Yet across industries, many organizations struggle to convert pilots into dependable business outcomes.  At CloudFronts, we’ve consistently seen why.  Whether working with Sonee Hardware in distribution and retail or BÜCHI Labortechnik AG in manufacturing and life sciences, AI success has never started with models. It has started with trust in data.  AI that operates on fragmented, inconsistent, or poorly governed data introduces risk not advantage. The organizations that succeed follow a different path: they build intelligence on top of trusted, enterprise-grade data platforms.  The Real Challenge: AI Without Context or Control  Most stalled AI initiatives share common traits:  This pattern leads to AI that looks impressive in demos but struggles in production.  CloudFronts has seen this firsthand when customers approach AI before fixing data fragmentation. In contrast, customers who first unified ERP, CRM, and operational data created a far smoother path to AI-driven decision-making.  What Data-Native AI Looks Like in Practice  Agent Bricks represents a shift from model-centric AI to data-centric intelligence, where AI agents operate directly inside the enterprise data ecosystem.  This aligns closely with how CloudFronts has helped customers mature their data platforms:  In both cases, AI readiness emerged naturally once data trust was established.  Why Modularity Matters at Enterprise Scale  Enterprise intelligence is not built with a single AI agent.  It requires:  Agent Bricks mirrors how modern enterprises already operate through modular, orchestrated components rather than monolithic solutions.  This same principle guided CloudFronts data architecture work with customers:  AI agents built on top of this architecture inherit the same scalability and control.  Governance Is the Difference Between Insight and Risk  One of the most underestimated risks in AI adoption is hallucination, AI confidently delivering incorrect or unverifiable answers.  CloudFronts customers in regulated and data-intensive industries are especially sensitive to this risk.  For example:  By embedding AI agents directly into governed data platforms (via Unity Catalog and Lakehouse architecture), Agent Bricks ensures AI outputs are traceable, explainable, and trusted.  From Reporting to “Ask-Me-Anything” Intelligence  Most CloudFronts customers already start with a familiar goal: better reporting.  The journey typically evolves as follows:  This is the same evolution seen with customers like Sonee Hardware, where reliable reporting laid the groundwork for more advanced analytics and eventually AI-driven insights.  Agent Bricks accelerates this final leap by enabling conversational, governed access to enterprise data without bypassing controls.  Choosing the Right AI Platform Is About Maturity, Not Hype  CloudFronts advises customers that AI platforms are not mutually exclusive:  The deciding factor is data maturity.  Organizations with fragmented data struggle with AI regardless of platform. Those with trusted, governed data like CloudFronts mature ERP and analytics customers are best positioned to unlock Agent Bricks’ full value.  What Business Leaders Can Learn from Real Customer Journeys  Across CloudFronts customer engagements, a consistent pattern emerges:  AI success follows data maturity not the other way around.  Customers who:  were able to adopt AI faster, safer, and with measurable outcomes.  Agent Bricks aligns perfectly with this reality because it doesn’t ask organizations to trust AI blindly. It builds AI where trust already exists.  The Bigger Picture  Agent Bricks is not just an AI framework it reflects the next phase of enterprise intelligence.  From isolated AI experiments to integrated, governed decision systems  From dashboards to conversational, explainable insight  From AI as an initiative to AI as a core business capability  At CloudFronts, this philosophy is already reflected in real customer success stories where data foundations came first, and AI followed naturally.  We hope you found this blog useful, and if you would like to discuss anything, you can reach out to us at transform@cloudFronts.com
