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 product is flexible."
"The solution is highly reliable."
"It is a scalable solution."
"The initial setup of this solution is very easy."
"The product is easy to use."
"The product is stable."
"IIS is easy to configure in terms of websites and other solutions."
"IIS has a very simple and user-friendly interface, which helps a lot in effective and efficient management."
"NGINX Controller is cheap compared to other solutions, and it offers significant cost and time savings."
 

Cons

"The only disadvantage I see is that the documentation is a bit difficult to find."
"IIS could improve by having some features related to URL rewrite, ARR (Application Request Routing) and HTTPS certificate generation."
"The documentation of IIS could be better. They are not easily accessible. I had to use YouTube and other online resources to learn how to use the solution properly."
"The visibility feature of the product is an area with certain shortcomings where improvements are required."
"The tool needs to improve its performance."
"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."
"We've never had any issues with the solution, but it's still nice to have overall improvements on it. It could be easier and faster to use, for example."
"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."
"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 licensing cost is dependent on the usage."
"Users can get a subscription-based license or a perpetual license for IIS."
"We pay a yearly licensing fee for the solution."
"We purchased a Microsoft Windows license and the license for IIS came in the package."
"The tool's pricing is on a yearly basis."
"It is licensed with your Windows installation which makes it relatively cheap if you already have a Windows Server sitting around."
"The product's price is not high."
"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."
