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

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

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

"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."

"It has good stability of the application server in the long term compared to other solutions."

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

"WebSphere Application Server is very stable."

"They offer good help to help resolve the issue."

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

More IBM WebSphere Application Server pros

"The product is resilient."

"NGINX is much easier to deploy and configure, and the skillset required to handle NGINX is more available in the market compared to deploying F5, Radware, or Citrix."

"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."

"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."

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

"Nginx is extremely efficient in terms of the connection rate to the CPU cycles ratio, and in terms of the bandwidth to CPU cycles."

"When you use NGINX, you have more options and power."

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

More NGINX Plus pros

Cons

"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."

"When compared with WebLogic, Weblogic is lighter and consumes less memory."

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

"WebSphere Application Server doesn't have an automated deployment option, forcing us to use third-party tools like Jenkins UCD and Palo Automated Deployment."

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

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

More IBM WebSphere Application Server cons

"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."

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

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

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

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

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

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

"NGINX is not cost-effective, especially for few applications, and is considered higher-priced."

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

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

"It is very expensive."

"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."

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

"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."

More IBM WebSphere Application Server pricing and cost advice

"HAProxy is cheaper than NGINX."

"You pay for each feature that you want."

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

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

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

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

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

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