  5. Caching:
    • Implement caching strategies to store frequently accessed data in memory, reducing the need to fetch the same data repeatedly from the database.
  6. Database Scaling:
    • Use database scaling techniques such as sharding, replication, and partitioning to distribute the database workload across multiple servers.
  7. Microservices Architecture:
    • Decompose your application into smaller, independent microservices. This allows for independent deployment, scaling, and maintenance of different parts of the system.
  8. Message Queues:
    • Implement message queues to decouple different parts of your application, enabling better scalability and fault tolerance.
  9. Optimized Database Queries:
    • Ensure that database queries are optimized for performance. Indexing, proper use of stored procedures, and minimizing the number of round trips to the database are essential.
  10. Content Delivery Networks (CDN):
    • Utilize CDNs to cache and serve static assets (images, scripts, stylesheets) closer to the end-users, reducing latency and server load.
