Costica Florea

Senior Manager, MW & DB Automation at a computer software company with 11-50 employees

Has worked seamlessly in complex clustered environments and supports long-term development efforts

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.

Nadeem-Inamdar

Senior Information Security Engineer at a tech company with 10,001+ employees

Advanced policies and web firewall have strengthened application protection and reduced attack traffic

There were some vulnerabilities in F5. They tried to fix it, but the fixes were not available at the time because they were zero days, so they attempted to fix it, but their support was not proper. Their support should be improved because sometimes features which we need for customization take time, and they are sometimes feasible and sometimes not feasible by the team, so their support and the engineering team should improve their product. I would like to see more features regarding customization which should be built into the application, and the tool optimization should be good, and the dashboard should be more crisp and clear.

Quotes from Members

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

Pros

"The solution has good performance."

"This solution is very good in terms of stability."

"It integrates well with the Tivoli Federated Identity Management system, which works as a single sign-on mechanism for other e-services that we have shared with other clients."

"IBM WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers."

"WebSphere Application Server's best features include the data subscription and connection viewer."

"This solution is easy to use with a GUI that is intuitive and very helpful."

"High availability, alert management, and deployments are the most valuable features for us. We have the ND version so we can do deployments."

"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."

More IBM WebSphere Application Server pros

"Application Gateway with application-level firewall tool and load distributor and balancer (also serves for A/B testing)."

"The primary valuable feature of NGINX for me is its ability to provide a reverse proxy."

"This solution has everything."

"Load-balancer feature, because I tried to do same with Apache 2.0 and HAProxy without sucess."

"The robust software architecture allows for it to be scalable and very stable."

"I would recommend this solution."

"-"

"NGINX works much better than HAProxy in our current hardware and architecture for HTTP/HTTPS load balancing. "

More NGINX Plus pros

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."

"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."

"Its price is a bit expensive. They should improve its price to compete with other applications that are out there, which we are also exploring."

"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 main issue we faced was its limited compatibility with non-Java technologies, which can result in difficulty detecting potential bugs and requiring additional integration efforts."

"I find the server okay, however, using the Maker instance, the Moving instance, and the Change instance is a little bit complicated without WebSphere knowledge."

"The solution is very expensive compared to an open-source stack."

"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."

More IBM WebSphere Application Server cons

"It would be good if NGINX provided a graphical user interface."

"The drawback is that you must obtain a license for everything."

"I would suggest adding GUI-based configuration panels to NGINX Plus to simplify setup and management tasks."

"I am not so happy with their pricing policy, but this is not the worse thing in my life."

"I would like to see the Grafana integration in NGINX which is already present in HAProxy. Grafana integration will help the solution visualize all the data analytics on the dashboard which is currently not present."

"Improvement needed in NGINX Plus could focus on optimizing memory usage for users."

"The scalability could be improved."

"The center management system could be improved."

More NGINX Plus cons

Pricing and Cost Advice

"The solution is quite expensive."

"When you purchase Maximo, you get WebSphere for free."

"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."

"It costs more than some of the others, but, you get what you pay for."

"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 is very expensive."

"The licensing cost is 1,000 of euros for a 30-year table."

"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."

More IBM WebSphere Application Server pricing and cost advice

"NGINX Plus is an open-source solution with limited additional features. When you try to get additional features in the solution, then you need to pay an extra amount to NGINX Plus."

"NGINX is a free tool in Brazil. There are some companies which do support it."

"I am not so happy with their pricing policy, but this is not the worse thing in my life. I can tolerate it."

"You pay for each feature that you want."

"I use the solution's community edition which is free of cost."

"Compared to other similar solutions on the market, I think it's over-priced."

"Nginx is free. I don't have experience with the Plus version."

"The solution is free, but you can spend a lot of money with a complex solution."
