The use of Windows Server 2019 in a corporate environment is one of the most practical solutions if we want to have global and centralized control of roles, services and functions that allow managing both users and computers and everything they can execute in the company.

What is IIS?
As we have mentioned, IIS (Internet Information Services), or also known as Windows Web Server is a feature that we can enable on our server with Windows Server 2019 to host web applications since when we install and configure IIS, our web server will manage applications with In order for them to process the messages that arrive using the default TCP ports, in this case for HTTP traffic it is port 80 and for HTTPS it will be port 443.
Throughout the world of web traffic, there are two process models for web servers to manage requests, these are:
- Management of requests in a single thread.
- Creation of new threads for each particular request.
IIS in Windows Server 2019 makes use of the creation of new threads for each request which in turn allows to capture a thread from an existing thread group for each request received.
IIS features
When using IIS we are talking about a feature that will be compatible with HTTP, HTTP / 2, HTTPS, FTP, FTPS, SMTP and NNTP protocols. In the new versions of IIS for Windows Server 2019 we find:
- Strict HTTP Transport Security (HSTS - HTTP Strict Transport Security) which allows a website to send a notification that it is a secure host and issue a report to browsers that should be contacted only through HTTPS (secure) connections .
- New IISAdministration cmdlets in PowerShell.
- Container improvements which help optimize executions in IIS work processes.
- Adding new server variables for the cryptographic protocol, the encryption algorithm, the key exchange algorithm and the message authentication algorithm, which seeks to increase the overall security of IIS.
- It allows to build and develop customized servers or with a special focus.
- Improves overall server performance.
- Reduce the web attack surface.
