A well-designed network infrastructure also includes security measures to protect data in transit and prevent unauthorized access. Implementing robust network security protocols, such as VPNs and encryption, is crucial to ensure the confidentiality and integrity of data transmitted between servers and client devices. Therefore, investing in a resilient and secure network infrastructure is paramount for any organization deploying server-based computing.
How Server-Based Computing Works
Server-based computing operates on a client-server architecture where the servers handle the heavy lifting of application execution and data storage. When a user interacts with a client device, their input (e.g., keyboard strokes, mouse clicks) is transmitted over the network to the server. The server processes this input, executes the application, and then sends back screen updates to the client device, which displays the results to the user.
This process effectively separates the application processing and data management from the user interface. Only keyboard and mouse inputs and screen updates are transmitted across the network, minimizing bandwidth usage and allowing multiple users to simultaneously access applications and desktop environments from various devices. This efficient use of network resources is a key advantage of server-based computing.
Centralized control is another significant aspect of how SBC works. Organizations can implement stringent access controls, monitor user activities, and deploy software updates efficiently from a central location. This centralized management enhances security, simplifies administration, and ensures consistency across the entire computing environment.
