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

"IBM WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers. Without a good application server, it would be hard to provide a secure layer of midddleware upon which the other applications run. IBM WAS improves the stability of the entire solution and provides a high quality platform for running web-based solutions."

"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."

"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."

"The solution is very stable and robust."

"If you want a product you can have confidence in, and a product with good availability, then IBM WebSphere Application Server is for you."

"I would not compare WebSphere and WebLogic because both servers are really good."

"IBM WebSphere Application Server works well and fulfills all of the requirements that are demanded of it, so it is a product that I recommend."

"The scalability of the product is quite good."

More IBM WebSphere Application Server pros

"NGINX provides a cost advantage, value addition, and effective support."

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

"I utilize NGINX for its capability to provide visibility and discovery options, helping discover and identify networks, which is crucial for ensuring application performance, managing latency, and checking server reachability."

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

"Valuable features include authentication, caching, reverse proxy routing, and load balancing."

"When I worked in a security research center, we tested NGINX to support DoS and DDoS attacks, and its results were great."

"The most valuable feature of the solution is that it is simple to configure."

"With NGINX, I appreciate its ability to route traffic geographically."

More NGINX Plus pros

Cons

"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."

"I think IBM WebSphere Application Server is a dead solution and will probably fade out."

"While WebSphere mostly supports IBM HTTP Server (IHS) as the web server plugin, I think it would be beneficial if it also supported Apache and NGINX web servers. That would give customers more flexibility in their choices."

"The support could be a bit more responsive."

"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."

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

"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."

"I would note that the response time is something IBM's support team needs to improve."

More IBM WebSphere Application Server cons

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

"Lack of a feature to print data on the terminal for verification of network traffic during debugging and testing."

"Our most challenging part was to run an older PHP website reverse-proxied through NGINX. That was not fun."

"The scalability could be improved."

"The solution's GUI is an area with certain shortcomings that need improvement."

"The center management system could be improved."

"One area of improvement could be that NGINX could provide a means to generate self-signed SSL certificates."

"It would be great if there was even more automation to make it even easier to maintain."

More NGINX Plus cons

Pricing and Cost Advice

"The pricing is a little expensive."

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

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

"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 solution is quite expensive."

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

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

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

More IBM WebSphere Application Server pricing and cost advice

"HAProxy is cheaper than NGINX."

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

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

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

"NGINX Plus is worth it, if you need it. If you do not need the features or support, the free and open source package is more than capable. "

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

"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."

"The cost is reasonable."
