It is used for the REST service.

The tool is stable.

Lacking documentation, difficult installation, but effective for large sized companies
Pros and Cons
  • "IIS is stable."
  • "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."

What is our primary use case?

I use IIS for issuing security certificates. For example, when I was trying to deploy direct access, it require a certificate which is issued from services. The service I used comes from IIS.

IIS is for large enterprises who would want to secure and make information private.

What needs improvement?

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.

For how long have I used the solution?

I have been using IIS for approximately a couple of months.

What do I think about the stability of the solution?

IIS is stable.

What do I think about the scalability of the solution?

I am the only one using this solution in my company.

The solution is scalable for large-sized companies.

How are customer service and support?

I have not used the support from IIS.

Which solution did I use previously and why did I switch?

I previously used Microsoft Active Directory. I started using IIS to see how can I deploy a secure certificate from my organization. Deploying certificates often require payment for various services. However, if you have a Windows Server, you can deploy it on-premises without having to go online. However, if you opt to avoid going online, you'll need to have an alternative process in place.

How was the initial setup?

I rate IIS a five out of ten. The time it takes for the deployment depends on your resources. If your resources are optimized, it will not take too long. You must have some knowledge of how to deploy it before you do it. However, typically the deployment takes 10 to 20 minutes.

What about the implementation team?

I did the deployment of the solution myself. Assistance would be useful for large enterprises for the department.

What's my experience with pricing, setup cost, and licensing?

I was using the trial version of IIS inside my virtual machines. 

ISS is included if you purchase a Windows Server license, then you can have the possibility to deploy different services. 

What other advice do I have?

I would not recommend this solution because there are easier-to-use solutions on the market.

I rate IIS a five out of ten.

Which deployment model are you using for this solution?

On-premises

Helpful support, scalable, and quick setup
Pros and Cons
  • "The initial setup of IIS is easy. The process takes only five minutes."
  • "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."

What is our primary use case?

We are using IIS for many purposes, such as creating the application pools, and websites, and defining the HTTP rules.

What needs improvement?

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.

For how long have I used the solution?

I have been using IIS for approximately eight years.

What do I think about the stability of the solution?

IIS is a stable solution for .NET applications.

What do I think about the scalability of the solution?

The scalability of IIS is good. We can expand the solution if we choose.

We have approximately 30 to 40 people using the solution in my organization.

How are customer service and support?

I was required to use the support from IIS a while ago when we were migrating from IIS 6.0 to IIS 7.0.

I rate the support from IIS a five out of five.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup of IIS is easy. The process takes only five minutes.

What other advice do I have?

We chose IIS because most of the applications we use are .NET and are Microsoft technologies that we are using for developing the application, IIS is the most valuable solution for this use case.

For first-time users of IIS, they should have some basic knowledge of what an application pool is, websites, and homepage redirections are.

I rate IIS a nine out of ten.

It's good and offers good usability.

The solution has been issue free.

It's stable and very reliable.

The solution scales well.

We have ten to 20 users currently using it. It is scalable. We do have a plan to increase usage, although I'm not sure of the exact plan.

It's a bit expensive and therefore not extensively used.

I did not previously use a different solution. This is the first tool of its kind that I have used. 

How was the initial setup?

It is straightforward to set up. We managed to deploy it in two to three weeks. We were able to migrate all the platforms over without issue. The architecture must be clear, and if that's the case, you don't have any issues.

We managed the setup ourselves in-house. We did not need any outside assistance from integrators or consultants while handling the implementation process. 

What was our ROI?

I have not witnessed any ROI while using the solution.
