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

"I have tried other tools (such as Apache), and found that IIS is more stable and easier on the memory for low resource systems."
"IIS is a reliable and secure product, works very well along side other components such as SQL and dotnet."
"I think that the IIS includes most features that are required by web applications so that they can run smoothly on Windows operating system."
"IIS works natively with Windows Server without any issues in publishing certificates."
"The solution has been reliable."
"The product is stable."
"IIS is a stable solution for .NET applications."
"IIS is quite easy to set up as it comes pre-configured, so I don't have to install anything."
"The products offers EE support."
 

Cons

"The areas of this solution that need improvement are monitoring, debugging, and troubleshooting."
"The initial setup was somewhere in the middle. It wasn't complicated but it wasn't easy either. The documentation isn't very good and the options are very complex."
"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's security needs improvement."
"The cost is a bit too high."
"In the next release, I would like to see better integration between the cloud environment and the on-premises environment."
"Microsoft products can only work within the Windows environment, which limits their versatility."
"Products based on Microsoft .NET do not give companies lot of options; either with Server Operating System shipped IIS, or the developer version called IIS Express."
"I would like to see integration with MQ systems."
 

Pricing and Cost Advice

"The product's price is not high."
"The price is good."
"The cost for IIS is already included in Windows services. We don't have to pay anything extra."
"We pay a yearly licensing fee for the solution."
"There is an annual license to use this solution and the price could be better."
"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."
"IIS's pricing is reasonable."
"The tool's pricing is on a yearly basis."
