•a) IAM (Identity and Access Management): Manages access rights and user permissions. Ensures that only authorized users can access specific AWS resources.
•b) Application Load Balancer (ALB): Distributes incoming application traffic across multiple targets. It helps manage and route requests efficiently, improving the availability and fault tolerance
•c) RDS Proxy: Manages database connections, improving scalability and security. It pools and shares database connections, reducing the load on database resources and improving performance.
•d) RDS (Relational Database Service): The main writable database instance: This is where all write operations occur and is the source of truth. It is the AWS service that makes it easier to set up, operate, and scale the PostgreSQL relational database in the cloud.
•e) Read Replica: It is the read-only copy of the primary database. It helps offload read queries from the primary database, improving performance and scalability.
Database Configuration:
•Primary Database will be the main write database, located in the primary AWS region.
•Read Replicas: Set up a few read replicas in the same or different AWS regions. These will handle read-heavy operations.
•Security Groups and Network Access:
•Configure security groups to restrict network access to the PostgreSQL instance based on team roles and access requirements.
•Monitoring and Logging:
•Enable PostgreSQL logs and monitor database activities to ensure compliance with access controls and performance optimization.
•By implementing this strategy, each team receives tailored access to the PostgreSQL database on AWS, ensuring security, performance, and scalability based on their operational needs.
