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

"IIS has a very simple and user-friendly interface, which helps a lot in effective and efficient management."
"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."
"Authentication for network appliances, load balancing products and wireless devices became easy to do."
"The product is flexible."
"The solution is very easy to use and offers a quick deployment."
"It is an easy-to-use and secure program."
"Stability-wise, I rate the solution a nine out of ten...Scalability-wise, I rate the solution a nine out of ten."
"The most valuable feature of IIS is that it's free, and it works."
"The products offers EE support."
 

Cons

"The solution's stability needs improvement."
"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."
"The price of the cloud system is a bit high."
"There is an issue with the network. The tool's price is also high."
"IIS needs immediate improvements, especially in the area of security management."
"Microsoft products can only work within the Windows environment, which limits their versatility."
"The tool needs to improve its performance."
"The graphical user interface has room for improvement and can be more user-friendly."
"I would like to see integration with MQ systems."
 

Pricing and Cost Advice

"The tool's pricing is on a yearly basis."
"I didn't need to get an additional license for the solution since it was included in my server."
"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."
"There is no license needed to use the solution."
"IIS's pricing is not expensive."
"There is an annual license to use this solution and the price could be better."
"We pay a yearly licensing fee for the solution."
"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."
