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.

More IIS pros

Cons

"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."

"I am using an older version of Windows Server IIS and the general management and navigation to get something done is not as straightforward as I hope it to be. The interface could be improved."

"The solution's black box is not fast."

"I would like to see NLB features in IIS."

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

"The solution's stability needs improvement."

"The customer service and support team can be improved."

"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."

More IIS cons

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

Pricing and Cost Advice

"We purchased a Microsoft Windows license and the license for IIS came in the package."

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

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

"I think it's part of the Windows Server, so you won't have any other costs to add in order to use the IIS service."

"There is an annual license to use this solution and the price could be better."

"The solution’s pricing is yearly. The pricing is affordable and not high."

"IIS is expensive."

"They offer a one-time payment model for the product license, and we pay annually for support."
