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.

Central console enables us to see all of the activated and deactivated computers but it has poor alerts and frustrating technical support
The solution needs to allow for other company product licenses to be included if possible. The solution needs to include other Microsoft products, like Exchange, SharePoint, etc. Right now, it's only for Windows and Office. The solution needs to be made web-based. Right now, we have to install some tools and to use these tools we have to log into a specific server. If that server has an issue we cannot manage it. The solution needs to be able to be managed from any machine. Alerting capabilities should be improved. If a license expires or there is a breach, or something is non-compliant, the solution should send out alerts.

Quotes from Members

Pros

Cons

"The cost is a bit too high."
"IIS needs immediate improvements, especially in the area of security management."
"The price of the cloud system is a bit high."
"The price of the solution could be less to improve."

"Finding the correct options are not more intuitive, and it should be."
"The solution is slow and could have better performance."

Pricing and Cost Advice

"We pay a yearly licensing fee for the solution."
"Users can get a subscription-based license or a perpetual license for IIS."

"I give the price of the solution a five out of ten."
"There is a license needed for the solution."
