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

"IIS fits properly for my business needs, with a lot of possibilities to upgrade the out-of-the-box functionalities, so it is really great."
"The solution is easy to use."
"The product is stable."
"It is a scalable solution."
"The initial setup of this solution is very easy."
"IIS is Internet Information Services, which is application infrastructure, and the main benefits include security control where you can control different access levels and integrate with other services to manage application security."
"All the features of Microsoft IIS are valuable."
"When you are working with Microsoft solutions, you will see that the integration with the operating system, and implementing some security features, are easier in IIS than when using another solution."
"Workflow functionality and internal portal capabilities are the most important features."
"The technical support is good."
"They integrated it with the SAP router."
"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."
 

Cons

"We'd like future versions to be more stable."
"The only issue I've encountered is with certificates not working fine sometimes. It's influenced by the server's service performance."
"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."
"The documentation is not very detailed."
"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 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 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."
"It lacks a few performance improvement tools."
"The user interface could be improved by making it more user-friendly."
"We encountered stability issues, especially on external functionality around its RFP capabilities."
"Due to our business, some setups were very complex."
"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."
"External portal functionality with suppliers and customers needs improvement."
"The cost of this solution is high."
 

Pricing and Cost Advice

"IIS's pricing is not expensive."
"IIS is expensive."
"It is licensed with your Windows installation which makes it relatively cheap if you already have a Windows Server sitting around."
"The tool is included with Windows."
"We pay a yearly licensing fee for the solution."
"The solution provides multiple licensing options."
"The licensing cost is dependent on the usage."
"There is a license needed for the solution."
"The cost of this solution is high."
"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​."
