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

The video tutorial explains Instagram's use of two database systems: Post SQL for relational data and Cassandra for NoSQL data. Post SQL employs a master-slave architecture to manage user information and relational data, while Cassandra uses a masterless architecture for user feeds and messaging. The tutorial highlights the benefits of each system, such as synchronization in Post SQL and auto-sharding in Cassandra. Instagram's architecture exemplifies polygode persistence, integrating both database types within microservices.

What type of architecture does Post SQL use in Instagram's database system?

• Client-server architecture

• Master-slave architecture

• Master-master architecture

• Peer-to-peer architecture

Which type of data is primarily stored in Instagram's Post SQL database?

• System logs

• User information and media

• Messaging data

• User feed counters

What is a key feature of Cassandra's architecture that benefits Instagram?

• Multi-directional communication

• Single point of failure

• Master-slave replication

• Centralized data storage

Why is Cassandra's auto-sharding feature important for Instagram?

• It enhances data security

• It simplifies database queries

• It optimizes disk usage and workload distribution

• It centralizes data storage

What is the term used to describe Instagram's use of both SQL and NoSQL databases?

• Database mirroring

• Cloud computing

• Polyglot persistence

• Data warehousing
