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 initial setup is simple."
"IIS is stable."
"The solution has been reliable."
"What I like most about this program is the fact that it's built into Windows, and then I also like the interface and the support."
"It helps scan and mitigates our vulnerabilities using the best protocols to secure our environment."
"What I like the most is that it is easy to use."
"IIS is quite easy to set up as it comes pre-configured, so I don't have to install anything."
"The solution is easy to use and connects with Microsoft, and the solution is very robust."
"The products offers EE support."
 

Cons

"Finding different settings can be difficult if you don't know where to look."
"IIS could improve the error logging. There are times we are not able to see the errors. More details would be helpful. Additionally, the configuring of the IIS should be allowed through coding instead of the classic view."
"The solution must improve the integration between its databases."
"In the next release, I would like to see better integration between the cloud environment and the on-premises environment."
"We'd like future versions to be more stable."
"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."
"At the moment, we have big problems with stability, and I'm not very happy at the moment. So, the stability could be improved."
"The product could be more compatible with Linux and macOS, particularly when applying user configuration policies."
"I would like to see integration with MQ systems."
 

Pricing and Cost Advice

"IIS's pricing is not expensive."
"I didn't need to get an additional license for the solution since it was included in my server."
"The yearly licensing cost is very high. The solution is very expensive."
"There is an annual license to use this solution and the price could be better."
"The licensing cost is dependent on the usage."
"The cost for IIS is already included in Windows services. We don't have to pay anything extra."
"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."
"The solution’s pricing is yearly. The pricing is affordable and not high."
