- 16. Server Based Computing (SBC) Overview Exploring End User Devices: From Evolution to Optimization Server Based Computing (SBC) Overview Server Based Computing (SBC) involves sending changed display information to end user devices and receiving keyboard strokes and mouse movements on the server. SBC requires limited network bandwidth and is commonly implemented in Windows environments using Windows Remote Desktop Service (RDS) or Citrix XenApp. Maintenance can be done at the server level in SBC, and server-side CPU and RAM capacity is shared among all users. Application configurations are the same for all users in SBC, ensuring consistency and ease of management. SBC allows for efficient use of resources but extensive use by one user can impact the performance of others.
- 17. Proper configuration of roaming user profiles, folder redirection for network storage, and application virtualization techniques can minimize limitations in desktop usage for both SBC and VDI. Minimizing Limitations in Desktop Usage Runs applications in their own virtual machine, providing exclusive use of operating system, CPU, and RAM to each user. May not scale well in terms of CPU resources and storage IOPS due to each client using an entire virtual machine. Virtual Desktop Infrastructure (VDI) Involves running applications on a server and sending changed display information to end user devices. Requires limited network bandwidth as only changed display information is sent to end user devices.
