IIS
IIS (Internet Information Services) is a flexible, secure, and manageable web server from Microsoft for hosting websites, web applications, and services on Windows Server. It supports protocols like HTTP, HTTPS, FTP, FTPS, SMTP, and NNTP, and integrates with technologies such as ASP.NET and PHP. IIS provides features like request filtering, URL rewriting, and load balancing to deliver scalable and reliable web hosting.
Developers should learn IIS when building or deploying web applications on Windows-based environments, especially for enterprise solutions, intranet sites, or services requiring tight integration with Microsoft technologies like .NET, SQL Server, or Active Directory. It is essential for roles involving Windows server administration, cloud hosting on Azure, or maintaining legacy systems that rely on Microsoft stacks.
