1. What Factors Influence the Choice Between Azure SQL Database and Cosmos DB? Presented by: [Golla kalyan Visualpath] www.visualpath.in +91-7032290546

2. Understanding Azure Data Storage Options Azure provides a diverse portfolio of database services, each engineered to address specific application requirements and data workloads. Among the most prominent are Azure SQL Database, a robust relational database service, and Azure Cosmos DB, a globally distributed, multi-model NoSQL database service. The optimal choice between these two powerful options hinges on a careful assessment of several critical technical and business factors. www.visualpath.in +91-7032290546

3. Relational vs. Non-relational Data Azure SQL Database Azure Cosmos DB Designed for structured, relational data where data integrity and well-defined schemas are paramount. Ideal for traditional applications requiring ACID (Atomicity, Consistency, Isolation, Durability) properties. A multi-model NoSQL database supporting various data models like document (JSON), key-value, column-family, and graph. Flexible schema allows for rapid iteration and handling of unstructured or semi-structured data. www.visualpath.in +91-7032290546

4. How Performance Needs Affect Selection Azure SQL Scaling Cosmos DB Scaling Offers vertical scaling (scaling up) by increasing compute tiers (DTUs or vCores) to handle higher workloads on a single instance. Best for predictable growth and contained data volumes. Provides horizontal scaling (scaling out) and global distribution. Data is automatically partitioned across multiple regions, enabling extremely low-latency reads and writes at a global scale. www.visualpath.in +91-7032290546

5. Geographical Reach and Data Replication Cosmos DB: Global by Design Azure SQL: Geo-Replication Offers native multi-region write and read capabilities with automatic data replication across Azure regions. This allows applications to have data geographically close to users, reducing latency and increasing availability. Supports geo-replication for disaster recovery and read-scale out, but configuration is more manual. Write operations are typically confined to a single primary region, with replicas for read operations or failover. www.visualpath.in +91-7032290546

6. Data Consistency Models Matter Cosmos DB Flexibility Offers five well-defined consistency levels: Strong, Bounded Staleness, Session, Consistent Prefix, and Eventual. This allows developers to fine-tune the balance between consistency, availability, and latency based on application needs. 1 2 Azure SQL: ACID Compliance Adheres to traditional ACID (Atomicity, Consistency, Isolation, Durability) transaction properties, ensuring strong consistency for all operations. Ideal for applications where data integrity is paramount and real-time consistency is non-negotiable. www.visualpath.in +91-7032290546

7. Query Support and Developer Experience Query Language T-SQL (Transact-SQL) SQL API (for JSON), MongoDB API, Cassandra API, Gremlin API, Table API Schema Strict, pre-defined schema Schema-agnostic (flexible) Joins Complex relational joins Limited, typically denormalized for performance SDKs ADO.NET, JDBC, ODBC, etc. Many languages (C#, Java, Python, Node.js, Go) www.visualpath.in +91-7032290546

8. Pricing Considerations DTU/vCore RU/s Azure SQL Database Azure Cosmos DB Pricing is primarily based on DTUs (Database Transaction Units) or vCores, which bundle compute, memory, and I/O resources. Costs are generally predictable for stable workloads but can escalate with sudden spikes. Pricing is based on provisioned throughput (Request Units per second - RU/s), which abstracts CPU, memory, and I/O. This model offers high cost-efficiency for highly variable or globally distributed workloads due to its elasticity. www.visualpath.in +91-7032290546

9. Making the Right Choice Azure SQL Database Azure Cosmos DB Key Assessment Areas Ideal for traditional OLTP (Online Transaction Processing) applications, existing relational workloads, and systems requiring strong transactional consistency with complex joins. Preferred for modern, real-time applications (e.g., IoT, mobile), globally distributed solutions, and scenarios demanding high throughput, low latency, and schema flexibility. Evaluate your data's structure, performance requirements, geographical distribution needs, and budget. These factors will guide you toward the most suitable Azure database service. www.visualpath.in +91-7032290546
