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 easy to use."
"The solution integrates well with most Microsoft products."
"My experience with the technical support by Microsoft at large is satisfactory."
"The most valuable feature of IIS is that it's free, and it works."
"Authentication for network appliances, load balancing products and wireless devices became easy to do."
"The best features of IIS are that you can design your own website and manage it yourself, creating as many websites as you want."
"All the features of Microsoft IIS are valuable."
"It's very easy to publish."
"The products offers EE support."
 

Cons

"The solution's black box is not fast."
"The scalability depends on how you have set it up. If you're running IIS on a single server, it might not be as capable as if you are on many in a cluster or with load balancing and so on."
"In the next release, the tool should be more easily integrated and configured with other provisions. The pricing should also be made cheaper since it's very expensive now."
"Sometimes if you are using IIS in large-scale scenarios, meaning that if you are deploying an application within IIS service and you are expecting a large number of users to use this application, you can sometimes find some problems, meaning that the service can shut down by itself unexpectedly if you don't configure your IIS with the correct configuration that can handle this number of users."
"IIS's memory management could be improved."
"Can be difficult to set up for new users and complex to troubleshoot."
"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."
"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

"IIS's pricing is not expensive."
"The yearly licensing cost is very high. The solution is very expensive."
"There is no license needed to use the solution."
"We pay a yearly licensing fee for the solution."
"I was using the trial version of IIS inside my virtual machines."
"I give the price of the solution a five out of ten."
"The tool is included with Windows."
"The licensing cost is dependent on the usage."
