BharathirajaSukumar - PeerSpot reviewer
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.
Erick  Karanja - PeerSpot reviewer
Offers high availability, straightforward deployment and easy to use
Tomcat could be a little bit more innovative. Tomcat could come up with a framework that's more lightweight and purely targeted at Java applications. Some other solutions are doing better right now, maybe because they have come up with MicroProfile, which I think is moving forward. It may actually beat Tomcat because of the lightweight nature of the framework, the MicroProfile. They're coming up with new solutions. So, for the future of Tomcat and to maintain the market share they might be looking for, they need to come up with initiatives to ensure that several of us have a lightweight framework to deploy applications on.

Quotes from Members

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

Pros

"WebSphere Application Server's best features include the data subscription and connection viewer."
"The only reason why we're currently using WebSphere is that the integration of the authentication with Azure is very quick. WebSphere has something that can immediately connect with Azure Active Directory."
"This solution is easy to use with a GUI that is intuitive and very helpful."
"The most valuable feature of this solution is Portal Virtualization."
"It has good stability of the application server in the long term compared to other solutions."
"The thing about WebSphere, as opposed to other ones that I am aware of such as JBoss and Liberty, is that WebSphere has the most comprehensive scaffolding available to it."
"Starting with version 8, WAS provides a special folder called monitor deployment. Once you put the .war or .ear file in there, it is deployed automatically without human intervention. This greatly helps us in our continuous integration server. Once the deployment binary is ready, we write a script to copy it to that folder and then, voila! The application is up and running and accessible from its context root."
"The solution is very stable and robust."
"Our company doesn't face any stability issues while using Tomcat."
"The ease of use of Tomcat is its most valuable feature. Once we grade particular software, we simply download it and we keep an eye on if Tomcat is working."
"The most valuable feature is the free EE server."
"I love Tomcat for its scalability, reliability, availability, and steadiness."
"The most valuable feature of this solution is that it supports Java Enterprise."
"It's very stable. No problems at all. I would rate the stability a ten out of ten."
"Tomcat is user-friendly and easy to set up, especially compared to WebLogic or JBoss where some specialty is required. If you are going for Tomcat, you can use their guidelines and can set it up easily."
"Tomcat's ease of use has positively impacted project timelines. Tomcat already has high availability – it doesn't go down so often and doesn't require a lot of maintenance. As long as your application works, you can depend on Tomcat."
 

Cons

"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."
"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."
"Sometimes, I feel WebSphere runs a bit slow. It might be loading unnecessary libraries, impacting its performance compared to other application servers."
"I think that this is a good product but I think that the cloud environment could be improved. I think that the future is in the utilization of the product in a product as a service way which is something that is lacking at this moment."
"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."
"The solution consumes hardware."
"It should be able to serve more concurrent requests like Oracle. Oracle has more powerful stability, availability, and real-time serving."
"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."
"Tomcat's stability could be improved, especially when handling more memory-intensive, large-scale applications."
"The solution's interface and backup features could be better."
"I think that Tomcat needs a more robust logging error details feature; the current logging feature is available, but it should be more user-friendly."
"Tomcat is not user-friendly. I would also like to be able to have multiple applications run at the same time."
"Deployment in Tomcat should be done through a GUI. We deploy applications from the backend using commands."
"Java functions should be built better into the solution."
"Tomcat needs to improve its stability."
"Our biggest challenge is that the Tomcat servers are not hosted locally."
 

Pricing and Cost Advice

"It's expensive."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"It is very expensive."
"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"The licensing policy is based on the PVU base."
"The pricing is a little expensive."
"It costs more than some of the others, but, you get what you pay for."
"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive. Bargain well and try to get as much discount as possible. Discounts of 85% are possible. Without the discount, I think the product is overrated."
"This is an open-source product and it's free to use."
"I rate the product's price an eight on a scale of one to ten, where one is a high price, and ten is a low price."
"It is an expensive product."
"The price of the solution is good."
"Tomcat is not costlier than other solutions."
"There are no additional costs apart from the standard license."
"The solution is open source so is free."
"It's open-source. We don't pay for the license."
