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

"What's most valuable in IBM WebSphere Application Server is its resilience. When you use the solution, you know that after the communication has been done, there will be no doubt that the data has reached its destination."

"IBM WebSphere Application Server is one of the best servers due to its stability and paid license."

"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."

"The product offers good performance."

"It does integrate well with the Tivoli Federated Identity Management system."

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

"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."

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

More IBM WebSphere Application Server pros

"The web application firewall feature has helped enhance security for our applications because most of the attacks which are performed on our website are being blocked by it, so the web application firewall is good."

"I need to highlight that the number one thing about NGINX is that it is free."

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

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

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

"Recently, we’ve needed to deploy sites over a number of servers to balance the load, which was not only painless but also super valuable."

"I would recommend this solution."

"This is a great product, it has everything."

More NGINX Plus pros

Cons

"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 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."

"The solution consumes hardware."

"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 installation is not straightforward and it can take three days."

"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."

"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive."

"The security could be better."

More IBM WebSphere Application Server cons

"NGINX is a very basic load balancer and cannot do as many customizations as F5."

"The center management system was not very good, maybe their new NGINX manager product is better."

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

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

"Only improvement needed that I would point to is scalability. With it, I mean clusterized organisation on a low level. At the moment, the best alternative is RHEL HA."

"The biggest room for improvement would be to allow NGINX Core machines to cluster for memory zones in some way with a plug and play module. "

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

"They should do in the open source version of what they did to Advanced HTTP, TCP, and UDP load balancing."

More NGINX Plus cons

Pricing and Cost Advice

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

"We pay around $200,000 annually."

"I don't remember the price, but there are no additional costs."

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

"The solution is quite expensive."

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

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

"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."

More IBM WebSphere Application Server pricing and cost advice

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

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

"HAProxy is cheaper than NGINX."

"It's an open source solution, so it's free."

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

"You pay for each feature that you want."

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

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