Design Microservices Architecture with Patterns and Principles - Design Instagram Database Architecture

The video tutorial explains Instagram's database architecture, which utilizes both Post SQL and Cassandra systems. Post SQL is used for relational data, employing a master-slave setup to manage user information and relationships. Cassandra, a NoSQL database, is used for user feeds and messaging, featuring a masterless architecture that allows for efficient data distribution and synchronization. The tutorial highlights the benefits of using both databases in a polygode persistence model, optimizing data management and performance across Instagram's platform.
