1. When to Use Azure Data Lake Instead of Azure SQL or Blob Storage Understanding the Right Storage Choice in Azure Data Architecture Presented by: [Golla Kaylan visualpath]

2. Introduction: Navigating Azure Storage Options Azure provides a powerful suite of storage solutions, each designed for specific needs. Choosing the optimal service is crucial for efficiency and cost-effectiveness. • Azure SQL Database: Relational data, transactional workloads. • Azure Blob Storage: Cost-effective object storage for unstructured data. • Azure Data Lake Storage (ADLS): Scalable analytics for diverse data. www.visualpath.in +91-7032290546

3. What is Azure Data Lake? Azure Data Lake (ADLS) is not just storage; it's a foundation for big data analytics. Built on Azure Blob Storage, ADLS Gen2 combines blob storage's scalability with Data Lake Store's advanced features, offering a unique solution for high-performance analytical workloads. www.visualpath.in +91-7032290546

4. When to Choose Azure Data Lake Massive Scale Diverse Data When dealing with petabytes of data, from raw logs to operational telemetry. Ingesting structured, semi-structured (JSON, XML), or unstructured (images, audio, video) data. Advanced Analytics Hierarchical Namespaces Powering complex ETL, machine learning, and AI workflows. Requiring file-system-like performance and granular security (ACLs) over objects. www.visualpath.in +91-7032290546

5. Azure Data Lake vs. Azure SQL Any format (structured, semi-structured, unstructured) Strictly structured (relational) Data Type Big data analytics, data science, batch processing Online Transaction Processing (OLTP), traditional OLAP Use Case Schema Schema-on-read (flexible, inferred at query time) Schema-on-write (rigid, defined before data ingestion) Scaling Massively scalable (exabytes) Scales vertically and horizontally (to TBs/PBs) Cost Model Pay-as-you-go for storage and transactions Pay-as-you-go for compute and storage Azure SQL excels at transactional consistency and normalized data, while ADLS provides the raw flexibility and scale for evolving analytical needs. www.visualpath.in +91-7032290546

6. Azure Data Lake vs. Blob Storage Analytics Optimization Optimized for analytics engines (Spark, Presto) with hierarchical namespace General purpose object storage; less optimized for direct analytics query Security Granular Access Control Lists (ACLs) on files and directories, POSIX-compliant Container-level security, Shared Access Signatures (SAS) Performance Higher throughput and lower latency for analytical workloads due to hierarchical namespace Good for large object transfers (e.g., VHDs, backups), but not file system performance Cost Slightly higher cost than standard blob storage, but offset by performance gains for analytics Lower cost per GB, ideal for archival and static content ADLS Gen2 is built upon Blob Storage but adds critical features for big data analytics, making it a distinct service despite sharing underlying infrastructure. www.visualpath.in +91-7032290546

7. Ideal Scenarios for Azure Data Lake IoT & Log Ingestion Raw Data Landing Zone Collecting massive streams of raw, unstructured IoT sensor data or application logs for real-time analysis. Storing unprocessed data from various sources (OLTP databases, ERP, CRM) before transformation. Data Science & AI/ML Multi-Source Data Lakes Providing a single source of truth for large datasets used in training machine learning models. Centralizing data from disparate systems for holistic business intelligence and reporting. www.visualpath.in +91-7032290546

8. Conclusion: Strategic Data Storage Azure Data Lake Storage is a cornerstone for modern data platforms, empowering organizations to unlock insights from massive, diverse datasets. It is purpose-built for analytics-at-scale. • Leverage ADLS for big data, varied formats, and advanced analytics tools like Synapse or Databricks. • Opt for Azure SQL for relational, transactional workloads and structured data. • Choose Azure Blob Storage for basic, cost-effective object storage and archival. Making informed choices ensures optimal performance, scalability, and cost efficiency for your Azure data architecture. www.visualpath.in +91-7032290546
