Keeping older Microsoft IIS applications running
Microsoft Internet Information Services (IIS) is one of the most popular web servers in the world. With an estimated market share of more than 30%, it’s the third most used web server in the world, behind Apache and nginx.
Many organisations have older web applications that depend on IIS. If yours is one of them, read on to find out how Cloudhouse can provide a simple way to keep applications running exactly like before, but with all the benefits of a modern operating system.
A long history
IIS was first released as a free add-on for Windows NT in 1995, and since that time has been continually enhanced and improved with regular updates. IIS 3.0 introduced the Active Server Pages (ASP) dynamic scripting environment. The latest release is Version 10.0, which is included as part of Windows Server 2019.
Over its long history, IIS has become a core component of application development on Windows. It’s used to host websites and web applications and is a key solution for hosting .Net web applications.
Security and compatibility challenges
This success has, not surprisingly, made IIS a target for bad actors: since 1999 more than 80 security vulnerabilities have been found and patched.
But regular updates and patches can also introduce compatibility challenges. Older ASP or ASP.NET applications can depend on components which are no longer supported on current versions of Windows. Many organisations find themselves with web applications which can no longer be run on modern versions of Windows Server, forcing them to retain older Operating Systems to host older websites.
These older operating systems in turn can introduce security vulnerabilities, and when the operating system reaches the end of its life cycle and it no longer supported, these vulnerabilities cannot be patched.
A difficult position
When an application forces a company to use an older version of a server, this generates a very difficult position – the choice between running older systems with unpatched vulnerabilities and accepting the risk of potential malware and ransomware attacks, or taking the costly decision to redevelop their applications from scratch to be compatible with a modern Windows versions.
But there is a third option. Cloudhouse Alchemy allows you to package up older applications so they will run on the latest versions of IIS, exactly like before – but with all the benefits of a modern operating system.
Proven track record
As an example, many applications depend on ASP.NET1.1, which is no longer supported on Windows Server 2016. The Cloudhouse Alchemy tool allows you to move your application onto the latest operating system with no need for code changes or user retraining. It’s just like magic!
Cloudhouse can package up older web applications to ensure they run successfully on newer versions of IIS. We can take applications from IIS 6.0 (Windows 2003) or later and provide compatibility enabling them to run on any modern version of IIS. We do this using templates that leverage internal IIS tools such as Web Deploy for exporting and restoring websites and settings. Our redirection engine allows us to match deprecated features of older IIS versions with the equivalent features on modern versions, providing complete compatibility with no need to redevelop the application.
We have delivered hundreds of IIS migrations like this, helping clients get up to date quickly, and removing the worry of incompatibility and malware attacks.
