Reduced server load: By serving cached content, the load on the server is reduced, allowing it to handle more requests and improving overall scalability. Cost savings: Caching can reduce the computational resources required for data processing and lower infrastructure costs by minimizing the need for expensive server resources.

In the web hosting service industry, it is commonly used for balancing the HTTP traffic across multiple servers which act together as a web front-end. A Load Balancer allows the users to distribute the traffic to a single IP across several servers by using a set of different protocols. How Does a Load Balancer Work?

Some servers have accelerators and you'll want their analysis tools installed as well: e.g., on Intel GPU servers, the intel-gpu-tools package; on NVIDIA, nvidia-smi. On cloud instances, adding Mbytes to the base server image can add seconds, or fractions of a second, to instance deployment time. This list is a minimum.
