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 is quite easy to set up as it comes pre-configured, so I don't have to install anything."
"The most valuable feature of IIS is the database it provides."
"The most valuable feature of the solution is that it is easy to use and easy to understand."
"The solution is very simple to use and easy to deploy."
"The initial setup is simple."
"IIS is a stable solution for .NET applications."
"The solution integrates well with most Microsoft products."
"The tool is very easy to use and efficient."
"NGINX Controller is cheap compared to other solutions, and it offers significant cost and time savings."
 

Cons

"Performance-wise, certain improvements in IIS are needed...IIS is not scalable. Its scalability is less."
"IIS has some stability issues and needs restarting."
"There is an issue with the network. The tool's price is also high."
"It is not compatible with other platforms due to limitations."
"The scalability depends on how you have set it up. If you're running IIS on a single server, it might not be as capable as if you are on many in a cluster or with load balancing and so on."
"In the next release, the tool should be more easily integrated and configured with other provisions. The pricing should also be made cheaper since it's very expensive now."
"The tool needs to improve its performance."
"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 technical support from NGINX Controller is not good. They do not offer quick responses or 24/7 support, which is lacking when immediate assistance is needed."
 

Pricing and Cost Advice

"The price of Windows Server IIS is expensive. They have a large user base, and they charge a little bit too much."
"The yearly licensing cost is very high. The solution is very expensive."
"The tool is included with Windows."
"Users can get a subscription-based license or a perpetual license for IIS."
"IIS is expensive."
"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."
"I didn't need to get an additional license for the solution since it was included in my server."
"The licensing cost is dependent on the usage."
