Application servers are very similar to the Web Servers. They provide some functionality to the clients with purposeful applications. Especially Tomcat, Wildfly or similar application frameworks are used to developed applications like programming languages Java, Python.
Proxy is an intermediate system which will redirect requests to the internet or LAN. Proxy servers provide different roles like authentication, internet access control and load balancing for web access.

- XEON CPU was designed for nonstop execution
- Motherboards generally contain two CPU sockets and slots for SCSI disk types.
- RAID Controllers are used to connecting and managing multiple disks. RAID Controller provides different disk configuration where speed and reliability can be achieved.
- SCSI Disks are specifically designed for server environments where 7×24 running disks are required.
