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.

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

"IBM WebSphere Application Server is easy to use."

"The solution is very stable and robust."

"The integration between IBM tools and applications is very well executed, and the support from IBM is quite good, providing a solid support structure."

"The solution is robust, and the connection management and the scalability which IBM provides to the stack are also valuable."

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

"Once you deploy your application, it will be very stable with no issues at all."

"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."

"The solution is very stable and robust."

More IBM WebSphere Application Server pros

"I think NGINX Plus is one of the most powerful and fittest solutions in this area, and I'd recommend it to others."

"This solution has everything."

"NGINX is the best available tool today for the tasks it covers."

"The load balancing module, which is equivalent to LTM, is the focus of the PSE, and so far, the features of both are identical, and I believe NGINX has more features for securing these services, but in terms of load balancing, both are massive solutions."

"It's lightweight software that can handle heavy loads efficiently."

"The web proxy and the database proxy are excellent."

"Using NGINX Plus for web traffic distribution is fantastic. It offers performance similar to physical load balancers but with added flexibility."

"NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps."

More NGINX Plus pros

Cons

"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."

"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."

"It should be able to serve more concurrent requests like Oracle. Oracle has more powerful stability, availability, and real-time serving."

"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."

"The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7."

"As the license cost is quite expensive, I'm rating it two out of five."

"The licensing could be improved, and I would like it to give the longevity of the lifespan of the visions."

"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."

More IBM WebSphere Application Server cons

"The KPI should be more focused on load balancing and the latency in application calling from the end system."

"The user interface could be improved."

"The solution needs to be easier to setup and deploy."

"The scaling should be built into the software rather than configured from an outside source."

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

"Initially, I experienced hiccups whenever I installed the application."

"NGINX Plus is moderately priced, but it could give better value for money."

"There is room for improvement in the pricing model."

More NGINX Plus cons

Pricing and Cost Advice

"We pay around $200,000 annually."

"It is very expensive."

"It's expensive."

"The licensing policy is based on the PVU base."

"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."

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

"WebSphere Application Server is expensive, so it may not be a good option for small companies."

"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."

More IBM WebSphere Application Server pricing and cost advice

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

"There's an open-source version of NGINX that is free."

"HAProxy is cheaper than NGINX."

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

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

"The price is the cost to contract support with a specialized company, usually during consulting hours."

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

"The list price of NGINX Plus is close to $5,500."
