IBM WebSphere Application Server is currently at version 9.0.5.23. In recent months, they released fix 23, as they periodically release fixes. Previously, they frequently increased versions, but now they maintain 9.0.5 with different releases. It's based on Java J2EE 7 and Java SDK 1.8. Oracle announced that 2030 will be the last year when Java SDK 1.8 will be supported. Oracle currently deploys Java 2.x in parallel, with the latest being version 25. The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7. I haven't found any white papers or official documentation from IBM outlining their trajectory post-2030.

Customization and flexibility enhance web applications while support effectively resolves queries
Regarding improvements in Tomcat, I personally haven't used it very extensively, but all Apache products are very useful for our web applications. Although the web server setup is a little different, it has everything we have been using, and as of now, everything is good with no deficiencies that need improvement. 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. This improvement would make error handling more user-friendly.

Quotes from Members

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

Pros

"IBM WebSphere Application Server is the ultimate product; there is nothing superior to IBM WebSphere Application Server, and while there are other options such as Tomcat, JBoss, and Oracle's solution, IBM WebSphere Application Server stands above them all."
"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."
"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."
"I find IBM support to be very nice."
"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."
"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."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"We use Tomcat for various purposes, and our company finds it to be perfect; we are getting all the solutions out of that."
"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."
"It is easy to set up."
"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."
"The product's most valuable feature is the ability to host applications."
"I like the solution’s ease of use."
"We can use Apache Tomcat for Java server applications."
 

Cons

"It should be able to serve more concurrent requests like Oracle. Oracle has more powerful stability, availability, and real-time serving."
"I think in some moments, the security was a little bit more complex to configure when it was delegated to other systems, making it an area where improvements are required."
"The availability of the solution needs improvement."
"In the next release of this solution, I would like to see support for the Arabic language."
"The licensing could be improved, and I would like it to give the longevity of the lifespan of the visions. In the next release, I would like to be able to download and extract the files so that I can just use my application server."
"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."
"IBM WebSphere Application Server hasn't changed much. It's still a heavyweight for any company compared to what you get. Unless your code base is deeply linked with it, I don't think it's a great idea to go with this solution. The current trend is toward modularity and containerization, and given the product's requirements, containerization will be difficult. There is a memory requirement as well."
"They should make the solution more lightweight and not bundle everything into a single product."
"I have no recommendations for improvements."
"Sometimes we face issues with the private and public networks and ensuring that once Tomcat is installed, that it is secure."
"Tomcat needs to improve its user interface."
"The setup is complex and could be improved."
"The solution cannot host .NET applications."
"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."
"The solution's interface and backup features could be better."
"The product needs to have more updates."
 

Pricing and Cost Advice

"We pay around $200,000 annually."
"The pricing is a little expensive."
"The licensing policy is based on the PVU base."
"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."
"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."
"The price of this product is higher than that of competitors."
"The solution is quite expensive."
"It costs more than some of the others, but, you get what you pay for."
"The price of the solution is good."
"We are using the open-source version."
"We are currently using the open-source version."
"It is an open-source tool and is free of cost."
"Tomcat is an open source solution."
"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."
"The solution is open source so is free."
"Tomcat is an open-source server."
