What is Windows Server?
Microsoft Windows Server is a series of server operating systems that manage shared resources and services for multiple users and devices at the same time. Businesses can operate it on virtual machines, physical hardware, or supported cloud infrastructure.
Windows Home and Pro can handle multiple user accounts, although they are designed primarily for endpoint usage on individual PCs. Windows Server is designed to centrally manage users, devices, programs, data, permissions, and network services inside an organization.
How Does Windows Server Work?
Windows Server works by receiving requests from clients, confirming who is asking, and then delivering back the right file, app, or service to the client. It can also manage hardware like CPU, memory, and storage behind the scenes.
So, what is Windows Server doing from start to finish? Here’s a simple flow:
- Request: A user requests to open a shared folder or sign in.
- Authentication: The server validates the account and permissions.
- Action: It delivers the file, app, or service.
- Logging: It logs activities for security and troubleshooting purposes.
- Management: Administrators centrally monitor and update everything.
For example, a company might host a Windows VPS with Windows Server, run IIS, launch an ASP.NET application, and make it accessible to website visitors. Apart from that, virtualization introduces another layer. With Hyper-V, a single physical system can run several virtual servers, keeping hardware active and lowering expenses.
