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.

Which deployment model are you using for this solution?

On-premises

Simple and user-friendly interface, good integration, and easy to implement
Pros and Cons
  • "IIS has a very simple and user-friendly interface, which helps a lot in effective and efficient management."
  • "Having no support for other than a Microsoft environment and programming languages limits the usage of IIS in many cases."

What is our primary use case?

I am working as a Software Project Manager for a software company in their Pharma Services Division and using IIS on Microsoft Windows Server for local deployment of our pharma related .NET application. It is built in C# and used for uploading and validation of pharma-related information in a locally deployed application by a team of data associates and data analysts.

The information is then transported after validation to the web database on Azure from the local database using an internally-developed desktop application.

How has it helped my organization?

IIS is the best option on Microsoft Windows Server for hosting and deployment of .NET applications, either in a local environment or on the web.

The graphical user-interface of IIS is very easy to use and helpful in the effective management of applications.

It comes with Microsoft Windows Server by default, which makes it easier to get started for hosting .NET applications immediately, with no hassles of installation and setup of any other web server.

The integration is the best, being a Microsoft .NET application hosted on Microsoft IIS running on Microsoft Windows Server with Microsoft Database Connectors and Drivers.

What is most valuable?

IIS has a very simple and user-friendly interface, which helps a lot in effective and efficient management. The simplicity of the interface helps the newbies to learn to manage it fast.

What needs improvement?

IIS needs immediate improvements, especially in the area of security management.

Having no support for other than a Microsoft environment and programming languages limits the usage of IIS in many cases.

The capability to host and deploy open-source applications would definitely add more value to it. There should be plugins to enable it to support open-source programming languages.

It also limits us in the choice of operating systems.

IIS should be enhanced in terms of its capabilities for monitoring and debugging.

For how long have I used the solution?

I have been using IIS on Microsoft Windows Server for more than five years.

What do I think about the stability of the solution?

It is very stable in its operations, hence requires minimum efforts in performance management. It is easy to keep it alive and maintain server uptime.

How are customer service and technical support?

We have found that customer support has always been good for cases that we have raised. It has a huge user community.

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

I have experience with Apache Web Server, WAMP, and XAMPP.

How was the initial setup?

Being a part of Microsoft Windows Server, it is very easy to set up and manage IIS.

Which other solutions did I evaluate?

I tried Apache Web Server before implementing IIS.

Which deployment model are you using for this solution?

On-premises

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 technical 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
