A simple and easy-to-use solution but not recommended for public apps

I would rate the overall solution a six out of ten. We have around five to six developers and engineers for the solution’s deployment and maintenance. You can use the solution if your website is not too big or complicated. However, if it is big and complicated, then you need to use Apache or Red Hat. This tool can be used for internal purposes. But if you plan to host a public app, then I wouldn’t recommend the tool.

Ensure seamless deployment and networking with a focus on critical uptime

The most important issue I've found is the blue screen errors, particularly when customers use external displays with a P-type cable. I have advised against using external displays for crucial applications and recommended using VGA or laptop adapter screens to mitigate this issue. However, the blue screen error remains a major concern because it causes data loss during reboots.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"What I like the most is that it is easy to use."

"Microsoft's technical support has always been very good."

"Windows Server IIS is stable."

"The tool shows us the operating systems where our servers and applications are running."

"The initial setup is simple."

"IIS is scalable."

"It's very easy to publish."

"It's good and offers good usability."

More IIS pros

"The product's deployment phase was very easy."

"It is very usable and easy to understand. Antivirus and VPN are the main features being used now. It allows my clients to access the network from home, which was very crucial because of the pandemic."

"The ability to seamlessly deploy, image, and patch without causing downtime is extremely helpful and user-friendly."

"The most valuable feature is AppFabric's hosting solution, which is what we need for running workflows."

Cons

"The documentation of IIS could be better. They are not easily accessible. I had to use YouTube and other online resources to learn how to use the solution properly."

"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."

"IIS needs to improve its security. Its support needs to be faster and clear. The tool's licensing could be cheaper as well."

"The solution is slow and could have better performance."

"IIS could improve by having some features related to ASR and HTTPS certificate generation."

"IIS could improve by Microsoft Windows improving the update services. We would like to be able to update all systems that are connected. The WSA service has to be in good order to accomplish this."

"The price of the solution could be less to improve."

"Compared to Linux, the solution’s Windows patching is slower. I would like to improve it."

More IIS cons

"The most important issue I've found is the blue screen errors, particularly when customers use external displays with a P-type cable."

"Its price and licensing policy can be improved. It could be a little cheaper. Licensing is sometimes confusing. There are so many different options. It is difficult to find out what to buy or what to choose for my necessity."

"Microsoft will stop supporting the product next year, and we can't run unsupported programs in our systems."

"The product is unable to connect with different cloud services."

Pricing and Cost Advice

"I give the price of the solution a five out of ten."

"IIS's pricing is not expensive."

"It is licensed with your Windows installation which makes it relatively cheap if you already have a Windows Server sitting around."

"IIS's pricing is reasonable."

"Users can get a subscription-based license or a perpetual license for IIS."

"I was using the trial version of IIS inside my virtual machines."

"The tool's pricing is on a yearly basis."

"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."

More IIS pricing and cost advice

"The product is affordable, in my opinion."

"It is expensive, and its licensing is a bit confusing."

Overview

Internet Information Services (IIS) provides a secure, easy-to-manage, modular and extensible platform for reliably hosting websites, services and applications. With IIS, you get choice and control without giving up reliability or security.

Microsoft

Windows Server AppFabric extends Windows Server to provide enhanced hosting, management, and caching capabilities for Web applications and middle-tier services. The AppFabric hosting features add service management extensions to Internet Information Services (IIS), Windows Process Activation Service (WAS), and the .NET Framework 4. This includes Hosting Services and Hosting Administration tools that make it easier to deploy, configure, and manage Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF) based services. The AppFabric caching features add a distributed, in-memory object cache to Windows Server that makes it easier to scale out high-performance .NET applications, especially ASP.NET applications.
