Efficient load balancing and the clustering, achieved by using the deployment manager, is valuable
I believe that the system is already good. However, for improvement or enhancement, it is user-friendly, but it could offer better choices on the front end for different aspects or options. Sometimes, I have to search extensively for features, as there are no upfront tabs. There is a lack of visible, easy, user-friendly, and straightforward options for the number of features.

Provides integration with Eggplant but problems with stability
We use Windows Server only for Eggplant Manager. Otherwise, I'm not using it   At the moment, we have big problems with stability, and I'm not very happy at the moment. So, the stability could be improved. I have been using it for a few years.  The initial setup is complex.  We have an…

Quotes from Members

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

Pros

"As compared to other applications, it has tremendous support. We have built internal capability so that we use it extensively internally. It is also easier to use with the outside data. You can write in ESQL, Java, or any other technology that you want to use for development. So, it is a lot more flexible in the language that it supports."
"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."
"Without the Admin Console it would be very hard to configure JVM settings, JDBC datasources, mail session settings, and security providers."
"The scalability of the product is quite good."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"One of the most valuable features might be the stability of the IBM WebSphere Application Server."
"Ease of administration: It has an Integrated Solutions Console, what we call the administrative console, with very detailed configurations and Help pages for each configurable item."
"The most valuable feature of this solution is Portal Virtualization."
"The initial setup of IIS is easy. The process takes only five minutes."
"The interface, simplicity, and ease of management are all good features that make this user-friendly."
"Windows Server IIS is stable."
"The solution is very simple to use and easy to deploy."
"IIS is scalable."
"IIS has a very simple and user-friendly interface, which helps a lot in effective and efficient management."
"What I like the most is that it is easy to use."
"The most valuable feature of IIS is it does not consume a lot of resources. It does not consume a lot of resources, such as memory."
 

Cons

"IBM needs to pay attention to market changes more quickly. We now have Java 9 and very soon Java EE8. We do not want to wait for two or three years after their release until they are supported by the new version."
"The business logic side of it is sort of missing in the sense that if I want to track and measure velocity, it is not really available. You have to buy another application and embark on a separate implementation. Instead of having different licensing, IBM DataPower should be integrated with WebSphere. It will allow us to build the business layer and rules a lot more efficiently, rather than developing rules within the application. It would be good if we can set up the business layer through parametrization rather than development. IBM DataPower has the business rule and the controls, and if it can be integrated, it would be fantastic. It will help the application in working better in terms of security features and business logic. If you're going to use it for open banking, you will be able to monitor velocity on the total pricing."
"When we run into memory or locking issues, we resort to using third-party tools. However, it would be preferable to have native tools for debugging this type of problem."
"Initial setup is very simple. Just use the IBM Installation Manager and add the packages. The install wizard takes care of the rest. The only thing that can be difficult is to find the right packages on the IBM website, because of all the changes that IBM does on its website(s)."
"When compared with WebLogic, Weblogic is lighter and consumes less memory."
"The availability of the solution needs improvement."
"While WebSphere mostly supports IBM HTTP Server (IHS) as the web server plugin, I think it would be beneficial if it also supported Apache and NGINX web servers. That would give customers more flexibility in their choices."
"Based on the field and based on the build that was provided, we've noticed a lot of constraints in terms of the performance now."
"The platform's stability could be better."
"IIS needs to improve its security. Its support needs to be faster and clear. The tool's licensing could be cheaper as well."
"The visibility feature of the product is an area with certain shortcomings where improvements are required."
"The solution is slow and could have better performance."
"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."
"The initial setup could be made easier."
"The solution should improve the cluster environment and load balancing."
"The solution's scalability needs improvement."
 

Pricing and Cost Advice

"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"The pricing is a little expensive."
"I don't remember the price, but there are no additional costs."
"We pay around $200,000 annually."
"The licensing cost is 1,000 of euros for a 30-year table."
"My company is on a perpetual or permanent license agreement with IBM WebSphere Application Server. There's also a pay-per-use option, but customers rarely choose that option. Most of the customers are on the perpetual license deal that's all-inclusive. As the license cost is quite expensive, I'm rating it two out of five."
"If your application is just a web app that does not need to scale big, you can obtain a single core license of WAS Express edition, which has almost the same features with limited processing cores. If you manage a very big application farm (i.e. need to run 10 or more WAS servers) it is better to get IBM WAS Hypervisor Edition."
"It costs more than some of the others, but, you get what you pay for."
"The tool's pricing is on a yearly basis."
"They offer a one-time payment model for the product license, and we pay annually for support."
"The price of the cloud system is a bit high."
"I was using the trial version of IIS inside my virtual machines."
"IIS's pricing is reasonable."
"Users can get a subscription-based license or a perpetual license for IIS."
"IIS comes along with an OS license from Microsoft. Others can opt for a perpetual-based licensing model to be able to use the system."
"We pay a yearly licensing fee for the solution."
