ICT Manager at Africa International University
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.

Geospatial Services Systems Administrator at EDIC Bayanat
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.

Head of Department of Infrastructure Development at SDA
Easy to use and maintain but the scaling could be improved
Pros and Cons
- "The solution is easy to use, easy to maintain and isn't too technical."
- "The solution should improve the cluster environment and load balancing."
What is our primary use case?
We primarily use the solution for the database and application system. We provide information systems for public and private companies.
What is most valuable?
The solution is easy to use, easy to maintain and isn't too technical.
What needs improvement?
The solution's security needs improvement.
The solution should improve the cluster environment and load balancing.
For how long have I used the solution?
I've been using the solution since 2006.
What do I think about the stability of the solution?
Occasionally we have a problem with stability.
What do I think about the scalability of the solution?
The scalability isn't so good. We have about 2,000 internal users, but externally we may have as many as one million users. Our service is public service. We do plan to increase usage.
How are customer service and technical support?
We have a contract with technical support and they have helped us with issues in the past. We've been satisfied so far.
How was the initial setup?
The solution is easy to set up. It took maybe an hour or two to deploy.
What other advice do I have?
We use the private cloud deployment model.
I'd rate the solution seven out of ten. I'd recommend the solution.

Senior System Administrator at a transportation company with 1,001-5,000 employees
A stable solution for our customer's websites or internal applications
Pros and Cons
- "This is definitely a stable solution."
- "The areas of this solution that need improvement are monitoring, debugging, and troubleshooting."
What is our primary use case?
We are a system integrator and this is one of the solutions that we assist our customers with. Our customers are primarily government departments, agencies, and ministries. These organizations are not very comfortable with using the cloud, so the majority of deployments are on-premises.
This solution is used for the customer's website or internal applications.
What needs improvement?
The areas of this solution that need improvement are monitoring, debugging, and troubleshooting. Having the monitoring as standard on the user interface would be nice.
There needs to be an easy way to escalate technical support issues beyond level one, quickly.
For how long have I used the solution?
I have been using this solution for more than fifteen years.
What do I think about the stability of the solution?
This is definitely a stable solution.
What do I think about the scalability of the solution?
Scalability is neither here nor there. You can say it's scalable, but it's an open-ended question because you have to consider whether you can host an application or product for country-wide use. I'd like to say no, but it can be used as part of a scalable infrastructure.
How are customer service and technical support?
We have contacted technical support, albeit rarely. I would rate them a six out of ten. It is not that they are slow to reply, but rather they are slow when it comes to understanding the problem. They often repeat the diagnostic steps that we have already performed.
The first level of support is not very good because by the time we speak with them, we are already past that point. This is because we do have experience and we can often solve the problems that are easy, or of medium-level difficulty. Consequently, if we have to open a support request then the problem is already difficult or complicated. We need to be able to escalate quickly. This is true in most cases, and the delay comes about because of the entry-level support people.
Which solution did I use previously and why did I switch?
In addition to this solution, we have worked with Apache Tomcat for Linux.
The choice of solution is dictated by the customer's requirements. If it is a Java application then we need to use Tomcat or Apache. If it's a .NET application in use then you need to use the IIS. It isn't a personal choice, or whether one is better than the other. Rather, it is about the application.
How was the initial setup?
The initial setup of this solution is very easy. The deployment takes between thirty minutes and two hours, maximum.
Usually, it will take one or two people to maintain this solution, including the website, if the whole infrastructure is Microsoft.
What about the implementation team?
We implement and deploy this solution for our customers. We have an internal technical team for this.
What other advice do I have?
This is a solution that I can recommend.
I would rate this solution an eight out of ten.
