A stable solution useful for the deployment of web applications
Pros and Cons
- "IIS is useful for the deployment of web applications...Its stability is good."
- "Performance-wise, certain improvements in IIS are needed...IIS is not scalable. Its scalability is less."
What is our primary use case?
IIS is useful for the deployment of web applications.
What is most valuable?
There aren't any particular features I found valuable since it is just used for deployment purposes.
What needs improvement?
Performance-wise, certain improvements in IIS are needed.
For how long have I used the solution?
I have been using IIS for not more than a year now. I also sell IIS.
What do I think about the stability of the solution?
Its stability is good. People use it widely to host their on-premises applications, like, internal applications on IIS.
What do I think about the scalability of the solution?
It is scalable if we include the application stack. IIS is not scalable. Its scalability is less. If we talk about its scalability with respect to the cloud, as we are seeing as of now, it's not that much scalable. We need to put some extra effort into making it scalable. Almost everyone who has a Windows server uses the solution for hosting their internal applications.
How was the initial setup?
The solution's initial setup is a little complex, especially compared to what others provide. It is better than Apache.
If there are no issues, the solution's deployment can be done in an hour or two maximum. Two people are required for the deployment and maintenance of the solution. Also, it depends on the size of the infrastructure and the servers and everything. The requirement for the infrastructure is not that big. So two people are more than enough. One is the administrator, and the other one is the developer. But if there is a lot of development, then the people required for deployment and maintenance would depend on the size of the application.
What's my experience with pricing, setup cost, and licensing?
The cost for IIS is already included in Windows services. We don't have to pay anything extra. We only pay for the Windows server.
What other advice do I have?
I would tell those planning to use the solution depending on their requirement. If the requirement is for on-premises and in an isolated environment, then people install it on the server and start using it. But if the requirement is to go on the cloud and make the website public, then it is preferable to opt for the cloud.
I rate the overall solution an eight out of ten.
