First and foremost, it's crucial to implement a distributed architecture. By dividing the application into microservices, each with its specific responsibility, we can scale individual components independently based on traffic demands. This modular approach allows for more efficient resource utilization and easier maintenance. Using containerization technologies like Docker, combined with orchestration tools such as Kubernetes, facilitates the deployment, scaling, and management of these microservices across multiple servers seamlessly.
Next, optimizing database interactions plays a vital role in handling high traffic. Implementing caching strategies using Redis or Memcached can significantly reduce the load on the database by storing...
