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.

"The products offers EE support."

Cons

"Presently, some developers do not have technical knowledge of managing IIS, so that needs to be improved in the next release."

"The only issue I've encountered is with certificates not working fine sometimes. It's influenced by the server's service performance."

"The solution should improve the cluster environment and load balancing."

"Microsoft products can only work within the Windows environment, which limits their versatility."

"The graphical user interface has room for improvement and can be more user-friendly."

"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."

"The solution's stability needs improvement."

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

More IIS cons

"I would like to see integration with MQ systems."

Pricing and Cost Advice

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

"There is no license needed to use the solution."

"The yearly licensing cost is very high. The solution is very expensive."

"The price is good."
