Flexible with high performance and good reliability
The solution scales well. As an example, there has been an American telecom service provider that had 20 million users, and the data of those user profiles had been stored on Dirx Directory, and they don't have any issues in retrieving the data and using it for any kind of services. Regarding our clients, the amount of users depends on if you have end users that don't really use this Directory or not. They are stored in this Directory and make use of the services that are administered via this Directory. There we are talking about millions. Then, you have administrators who configure the Directory and there we're talking about, let's say, hundreds of users.

Integrated web hosting has simplified secure services and has supported long-term growth
To be honest, I do not see any major areas for improvement. Perhaps something simple and minor. It should not go more complex than it is at the moment. The only disadvantage I see is that the documentation is a bit difficult to find. There is a lot of configuration that is very hard to get information about.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution offers high performance."
"The flexibility of the product."
"The role and attribute-based access control has been greatly improved."
"The most valuable feature is its knowledge."
"DirX Directory is the best feature of the product: a very fast, stable LDAP directory."
"The solution is extremely stable; typically if you don't change the setup, the configuration, or anything, it will be running for decades and nothing will happen as an issue."
"All the features of Microsoft IIS are valuable."
"My advice for anybody who is considering this solution is to go ahead with it."
"Stability-wise, I rate the solution a nine out of ten...Scalability-wise, I rate the solution a nine out of ten."
"It is a lightweight web host that is easy to configure for simple webpages."
"IIS is easy to configure in terms of websites and other solutions."
"The stability is better than it was in the past."
"The solution integrates well with most Microsoft products."
"My advice to others is this is a simple-to-use solution and you can find items with ease."
 

Cons

"The price could be better. It would be better if they developed a better endpoint solution in the next release."
"The Self-Service Portal is old school and it lacks easy accessibility for users."
"An overall modernization of the product is required in order to keep up with newer products."
"The product provides an excellent framework but could use some polish on the front end to reduce the amount of configuration required for basic tasks."
"The user interface could be more convenient for people that don't know the tool too intensively."
"Needs more available consultants and implementation partners."
"We've never had any issues with the solution, but it's still nice to have overall improvements on it. It could be easier and faster to use, for example."
"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."
"Scalability issues: No issues encountered but always go for two machines as one isn't enough and isn't fault redundant."
"Can be difficult to set up for new users and complex to troubleshoot."
"Sometimes if you are using IIS in large-scale scenarios, meaning that if you are deploying an application within IIS service and you are expecting a large number of users to use this application, you can sometimes find some problems, meaning that the service can shut down by itself unexpectedly if you don't configure your IIS with the correct configuration that can handle this number of users."
"Sometimes, we encounter difficult issues, and getting support from Microsoft to resolve those issues is not easy."
"The visibility feature of the product is an area with certain shortcomings where improvements are required."
"The solution's pricing and stability need improvement."
 

Pricing and Cost Advice

"The price could be better."
"IIS's pricing is reasonable."
"This solution comes included with Windows Server."
"I didn't need to get an additional license for the solution since it was included in my server."
"We purchased a Microsoft Windows license and the license for IIS came in the package."
"The licensing cost is dependent on the usage."
"The tool's pricing is on a yearly basis."
"I think it's part of the Windows Server, so you won't have any other costs to add in order to use the IIS service."
"The price is good."
