The interface, simplicity, and ease of management lend flexibility to this configurable solution
Pros and Cons
  • "The interface, simplicity, and ease of management are all good features that make this user-friendly."
  • "Scalability issues and security concerns need attention from Microsoft."

What is our primary use case?

We are basically using IIS like people use SharePoint. Technically IIS is a configurable web server. SharePoint is meant to be a collaborative tool. We configured IIS to be a collaborative tool of our own design.  

What is most valuable?

The most valuable parts of IIS are the interface, simplicity, and ease of management.  

What needs improvement?

There are a lot of security issues with IIS, and this has become more of a concern, especially recently. That security problem is the biggest disadvantage.  

Scalability is also a problem. Microsoft needs to improve on that aspect of the product. There are many limitations on IIS that seem like they should not be hard to remedy.  

On the other hand, Microsoft is doing more to concentrate on Azure for the cloud solution, so it may be their intent that Azure is ultimately the better solution.  

For how long have I used the solution?

Overall, I have been working with IIS solutions on the cloud and on-premises for eight to ten years.

What do I think about the stability of the solution?

Recently IIS has been more stable than in earlier releases and it has gotten better as it matured.  

What do I think about the scalability of the solution?

I do not think that much of IIS as a very scalable solution. It is used by our entire organization, which is about 1,000-plus end-users. But the product itself has limitations built into it.  

We have a maximum of two people who manage the product. We work with it somewhat less now because of the scalability limitations and security issues, so we also dedicate less staff to projects with the product.  

How are customer service and support?

The technical support is neutral: not good and not bad. It has become less satisfying because they changed how support is handled and we have to depend on forums. We do not have direct access to Microsoft support, in other words. It is not at all optimal.  

Microsoft tries to divert from this lack of interest in supporting the product, I think, by providing documentation. We also use the community and go into the forums — the Microsoft TechNet forums — and then use Google as a last resort. For technical support on IIS, it turns out that Google is our best friend.  

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

From the beginning, we have been using Microsoft products as our base solution. We have Unix and Apache and those things in addition in the places where we need them, but we are mainly running on IIS and Windows.  

How was the initial setup?

The initial setup was straightforward. That is one of the biggest advantages for IIS. It takes just three or four clicks and the installation is done. The whole process takes just a few minutes.  

What other advice do I have?

Recent versions, especially IIS 10, are very stable. For the stability I highly recommend IIS.  

On a scale from one to ten where one is the worst and ten is the best, I would rate IIS as an eight-out-of-ten.  

Which deployment model are you using for this solution?

On-premises

Easy to use, integrates will with Microsoft well, and offers a simple initial setup
Pros and Cons
  • "The solution integrates well with most Microsoft products."
  • "If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."

What is our primary use case?

We primarily use the solution for application infrastructure.

What is most valuable?

The solution is easy to use.

The solution integrates well with most Microsoft products.

What needs improvement?

The solution doesn't integrate well with all Microsoft products. There are a few that actually don't integrate well with IIS.

If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages.

For how long have I used the solution?

I've been using the solution for ten years.

What do I think about the stability of the solution?

The solution is stable.

What do I think about the scalability of the solution?

It's a good solution, but we don't use it on a large scale, so I'm not sure how well it scales. Currently, we have 250 users on it. Most are end-users, but we do have five admins on the solution as well.

How are customer service and technical support?

We've never reached out to technical support. Mostly if we have issues, we look to community support for answers.

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

We also use Apache Web Server side by side with IIS.

How was the initial setup?

The initial setup is very straightforward.

What about the implementation team?

We handled the implementation ourselves.

What other advice do I have?

We use the on-premises deployment model.

I'd recommend IIS for almost everything. I would suggest using use case scenarios.

I'd rate the solution eight out of ten.

Easy to use GUI, but support for clustering needs to be included in this solution
Pros and Cons
  • "The graphical user interface makes it easy for users to configure the sites."
  • "This solution needs to be easier for cases where you want to have an IIS cluster."

What is our primary use case?

We have a GIS solution from ESRI, ArcGIS Web Adaptor, and it is installed on top of IIS. It's part of ArcGIS Enterprise solution.

What is most valuable?

The graphical user interface makes it easy for users to configure the sites. 

What needs improvement?

This solution needs to be easier for cases where you want to have an IIS cluster. If you have several IIS solutions running, it is not clear on how to make them communicate to each other. Normally, IIS Web Server run independently on each server. To have "IIS cluster", currently you need to have a network load balancer (NLB) appliance running in front of them. We use NLB to distribute the load and have high-availability of IIS Web Server.

For how long have I used the solution?

I have been using this solution for more than twenty years.

What do I think about the stability of the solution?

This solution is stable. However, because of the way IIS interacts with the application pool, it is possible that another application running in different application pool, can have an impact to other application pool. Theoretically, each application pool will have independent process and should not conflicting between each other.

What do I think about the scalability of the solution?

This is something that we are looking into because we want to have IIS Web Server that can communicate between each other. So far, we cannot find this options inside it, anywhere on the menu.

In our office, we only have few people who use this solution and we don't have a plans to increase its usage. It is for internal publishing only.

But for our client, we implement this solution in production environment and so far, no critical issue happened to run IIS Web Server on it.

How are customer service and technical support?

We have not been in contact with technical support. So far, we have been able to handle all issues.

How was the initial setup?

The initial setup of this solution is simple. Even if you aren't familiar with it, it is not complex. If you are installing it inside Windows Server, it will take less than half an hour to deploy. In most cases, it can be done in fifteen minutes.

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

This solution comes included with Windows Server.

What other advice do I have?

My advice for anybody who is considering this solution is to go ahead with it. This is a mature product that is suitable for production environment. It competes with the Linux-based web server, which has more features. However, Microsoft is becoming more friendly with the open-source community, so hopefully they will implement more advanced features inside IIS.

It seems to me that Microsoft has been evolving the product with one of the main goals to be ease of use. However, I think that they need to focus on handling the biggest load. 

I would rate this solution a seven out of ten.
