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 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."

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

"It is very stable, safe, and secure."

"The performance is good."

"It's an awesome solution. Compared to everything else that's out there in the market right now, IBM MQ is hands down the best solution available and that's based on 40 years of IT experience."

"The scalability of the product is quite good."

"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's data consistency is great and very reliable, which is critical for us in a transitional scenario and the most important feature that we count on."

More IBM WebSphere Application Server pros

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

"NGINX Plus' most valuable feature is the ingress controller."

"Supports IMAP, POP and SMTP protocols for the reverse proxy."

"The overall product rating is ten out of ten."

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

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

"Its most valuable features are load balancing and application delivery. This is the most efficient application for these features because of stability and its efficiency."

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

More NGINX Plus pros

Cons

"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."

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

"The footprint could be reduced so that we can use a smaller virtual machine to run the application. We could also use more scripts. I would like this solution to be more script oriented, rather than GUI oriented."

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

"The solution consumes hardware."

"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."

"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."

More IBM WebSphere Application Server cons

"Initially, I experienced hiccups whenever I installed the application. As with any application, there were initial issues, however, after receiving support, everything was rectified."

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

"Instance service health check on the NGINX load balancer feature could be improved."

"I would like it to have a more user-friendly graphical interface."

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

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

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

More NGINX Plus cons

Pricing and Cost Advice

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

"It's expensive."

"We pay around $200,000 annually."

"It is very expensive."

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

"The pricing is a little expensive."

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

"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."

More IBM WebSphere Application Server pricing and cost advice

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

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

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

"The cost is reasonable."

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

"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 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."

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