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

"This solution is very good in terms of stability."

"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 the best in terms of scalability and performance, as well as the support for managing distributed transactions."

"I find IBM support to be very nice."

"The scalability of the product is quite good."

"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."

"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."

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

More IBM WebSphere Application Server pros

"The product is lightweight and fast."

"The flexibility of its modules allow it to be scalable."

"I receive very good support."

"Zero Downtime has always been a strength in recommending infrastructure web services, and NGINX allows me to execute such infrastructure with less complications and the ability to switch from server to server easily."

"The product is resilient."

"NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps."

"The best solution, by far, for web traffic control for things in production and just around the house."

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

More NGINX Plus pros

Cons

"Initial setup is very simple. Just use the IBM Installation Manager and add the packages. The install wizard takes care of the rest. The only thing that can be difficult is to find the right packages on the IBM website, because of all the changes that IBM does on its website(s)."

"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."

"Some things are very difficult to do, so the interface and usage could be more intuitive for those."

"The main problem is the licensing cost of the product. The product can scale but the budget cannot."

"Stability is frustrating. It goes down after a specific number of user connections."

"The solution consumes hardware."

"WebSphere is very cumbersome and not user-friendly."

"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."

More IBM WebSphere Application Server cons

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

"The solution must improve its performance."

"The scalability could be improved."

"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."

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

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

"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."

"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

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

"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."

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

"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."

"When you purchase Maximo, you get WebSphere for free."

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

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

"It is very expensive."

More IBM WebSphere Application Server pricing and cost advice

"NGINX is a free tool in Brazil. There are some companies which do support it."

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

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

"HAProxy is cheaper than NGINX."

"The cost is reasonable."

"You pay for each feature that you want."

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