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

"Security: It is compatible with the latest Java 8 security features, supports FIPS 140-2 and NIST SP 800-53 with strong ciphers and cryptography keys, and supports TLS 1.2 completely. Also, configuring client and server certificates is relatively easy."
"The solution is very stable and robust."
"I find IBM support to be very nice."
"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."
"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."
"This solution is easy to use with a GUI that is intuitive and very helpful."
"The integration between IBM tools and applications is very well executed."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"The most valuable features of this solution are the general web server features."
"We can use Apache Tomcat for Java server applications."
"One of the most valuable features of Tomcat is its compatibility with the Apache web server and its ease of configuration. It is simple to set up and maintain and allows for easy management of database connections, transactions, and isolation. Overall, Tomcat is a user-friendly application server that makes it easy to manage various aspects of database interactions."
"The solution integrates smoothly with the development environment. The integration process is straightforward. You only need to configure the project in your IDE. With intelligent features, the integration becomes even easier. Once integrated, deployment into our application is straightforward. Previously, we sometimes relied on manual deployment processes or used a separate application manager. However, with this solution, deployment is simplified."
"Tomcat is a simple, light environment, whereas the full Red Hat Fuse solution is heavier."
"It's very stable. No problems at all. I would rate the stability a ten out of ten."
"Web apps are very easy to deploy."
"Tomcat is easy to handle, its installation process does not take much time, and its server speed is also very good compared to other servers."
 

Cons

"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."
"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."
"Sometimes, I feel WebSphere runs a bit slow. It might be loading unnecessary libraries, impacting its performance compared to other application servers."
"WebSphere is very cumbersome and not user-friendly."
"The solution consumes hardware."
"What could be improved in IBM WebSphere Application Server is its interconnection with other products, for example, Kafka. What I'd like to see in the next release of the solution is a better graphical user interface."
"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."
"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."
"The high availability is not as robust as the competition is such as WebLogic and Jboss."
"I have no recommendations for improvements."
"Tomcat is not user-friendly. I would also like to be able to have multiple applications run at the same time."
"Java functions should be built better into the solution."
"The stability must be improved."
"It would be great if they offered more integration of monitoring tools."
"The solution's interface and backup features could be better."
"The setup is complex and could be improved."
 

Pricing and Cost Advice

"The solution is quite expensive."
"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."
"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."
"It is very expensive."
"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."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"I give the pricing an eight out of ten."
"Tomcat is open-source and free to use."
"If it is a community version of the solution, no payment is required. However, if it is a Linux version, we must buy the solution from JBoss."
"We are using the open-source version."
"This is an open-source product and it's free to use."
"The solution is free."
"The tool is free."
"The solution is open source so is free."
