Description: A backend server pool refers to a collection of servers that work together to process and manage user requests, receiving traffic from the load balancer. These servers are responsible for executing business logic, accessing databases, and providing the necessary data for applications to function correctly. The architecture of a backend server pool allows for distributing the workload across multiple servers, improving efficiency and service availability. By implementing a backend server pool, horizontal scaling can be achieved, meaning more servers can be added as demand increases, ensuring the system can handle a higher volume of traffic without compromising performance. Additionally, this setup provides redundancy; if one server fails, others can take over its load, thus minimizing downtime. In the cloud context, backend server pools are essential for modern applications, as they allow businesses to leverage the elasticity and scalability offered by cloud service providers, optimizing resource usage and reducing operational costs.
