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

"The solution is very stable and robust."

"IBM WAS is the backbone for our enterprise content management suite which delivers the primary processes for our customers."

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

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

"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."

"Network Deployment is the most useful feature for scalability. It has many features within the standard WebSphere Application Server edition."

"The technical support from IBM is very good and responsive."

"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."

More IBM WebSphere Application Server pros

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

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

"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."

"The most valuable features are the gateway and the ability to publish to sites."

"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."

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

"I would recommend this solution."

More NGINX Plus pros

Cons

"The installation has room for improvement."

"Its price is a bit expensive. They should improve its price to compete with other applications that are out there, which we are also exploring."

"I'd like to see the ability to build clusters made a little bit easier. It is kind of a manual process right now and this would just help save time and reduce resources."

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

"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 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."

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

"The solution is very expensive compared to an open-source stack."

More IBM WebSphere Application Server cons

"Improvement needed in NGINX Plus could focus on optimizing memory usage for users."

"The drawback is that you must obtain a license for everything."

"The solution must improve its performance."

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

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

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

"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."

"Make modules easier to enable or disable. The beauty and ugly side of the NGINX modules is you have to know how to compile the module. For beginners or non-very technical aspirant(s) going for NGINX, they have to learn how to compile the modules."

More NGINX Plus cons

Pricing and Cost Advice

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

"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."

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

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

"We pay around $200,000 annually."

"The solution is quite expensive."

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

"The price of this product is higher than that of competitors."

More IBM WebSphere Application Server pricing and cost advice

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

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

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

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

"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."

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

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