Systems Engineer at Atos
Designs and manages multiple websites while ensuring data backup and disaster recovery
I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.

Quotes from Members

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

Pros

"The product is scalable."
"IIS is stable."
"The solution is easy to use and connects with Microsoft, and the solution is very robust."
"It is a Microsoft product that is easy to use and to host local and public websites."
"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."
"All the features of Microsoft IIS are valuable."
"What I like most about this program is the fact that it's built into Windows, and then I also like the interface and the support."
"This is definitely a stable solution."
"The products offers EE support."
 

Cons

"The customer service and support team can be improved."
"Finding different settings can be difficult if you don't know where to look."
"IIS could improve by having some features related to URL rewrite, ARR (Application Request Routing) and HTTPS certificate generation."
"The platform's stability could be better."
"The solution's pricing and stability need improvement."
"The documentation is not very detailed."
"It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it."
"Performance-wise, certain improvements in IIS are needed...IIS is not scalable. Its scalability is less."
"I would like to see integration with MQ systems."
 

Pricing and Cost Advice

"The yearly licensing cost is very high. The solution is very expensive."
"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."
"IIS's pricing is reasonable."
"The solution provides multiple licensing options."
"The product's price is not high."
"This solution comes included with Windows Server."
"The tool is included with Windows."
"The price of the cloud system is a bit high."
