Krishnakumar Natarajan - PeerSpot reviewer
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 solution is easy to use."
"All the features of Microsoft IIS are valuable."
"We use Windows Server only for Eggplant Manager."
"The tool shows us the operating systems where our servers and applications are running."
"Authentication for network appliances, load balancing products and wireless devices became easy to do."
"The solution has been reliable."
"The solution is very stable. The solution is very simple and easy to use."
"The best features of IIS are that you can design your own website and manage it yourself, creating as many websites as you want."
"Workflow functionality and internal portal capabilities are the most important features."
"Internal workflow approval around ESS and MSS leave days, capex approval as well as internal communication to the business have improved the way my organization functions."
"From the use of this solution, we have been able to establish better processes and have greater management of our company."
"They integrated it with the SAP router."
"The technical support is good."
 

Cons

"The price of the cloud system is a bit high."
"IIS could improve the error logging. There are times we are not able to see the errors."
"The solution should improve the cluster environment and load balancing."
"I see that IIS has maintained the same interface for a long time, so they could potentially use more automation or integrate Copilot into it to make it easier to use."
"The solution is slow and could have better performance."
"I would like to see NLB features in IIS."
"The documentation is not very detailed. They need to improve it and add to it. They should ensure there are lots of visuals to help users better understand the solution."
"It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it."
"We encountered stability issues, especially on external functionality around its RFP capabilities."
"The user interface could be improved by making it more user-friendly."
"The cost of this solution is high."
"Our customers expect that a page will open within one second, and I doubt this will happen. Also, opening documentation takes time. Fixing this will help the customer and help to meet their expectations."
"Due to our business, some setups were very complex."
"External portal functionality with suppliers and customers needs improvement."
 

Pricing and Cost Advice

"IIS is expensive."
"We purchased a Microsoft Windows license and the license for IIS came in the package."
"IIS comes along with an OS license from Microsoft. Others can opt for a perpetual-based licensing model to be able to use the system."
"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 no license needed to use the solution."
"The tool's pricing is on a yearly basis."
"The price is good."
"The cost for IIS is already included in Windows services. We don't have to pay anything extra."
"Because India is so competitive in the IT world, people will start to move away from SAP's pricing because they have a market monopoly. Soon, they will start losing the monopoly part to open source and other things. I don't think their monopoly will run for more than three to four years because people are getting away from these monopolies."
"​SAP is not for every business. It depends on what is required. SAP is always going to be expensive​."
"The cost of this solution is high."
