To ensure that the website is highly available and scalable, the project team implemented various strategies, including load balancing, caching, and CDN (Content Delivery Network) services. Load balancing helps distribute the incoming traffic to multiple servers, ensuring that no single server becomes overloaded. Caching is used to store frequently accessed data in memory, reducing the number of database queries required to serve each request. CDN services are used to store static content, such as images and videos, on servers closer to the users, improving the website's performance and reducing latency.
