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.

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

"I would say that the clustering, achieved by using the deployment manager, is valuable, as there is a load balancing feature that uses different nodes, handled by the deployment manager, and this functionality helps with the load balancing of applications."

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

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

"The solution is very stable and robust."

"The performance is good."

"The solution is robust, and the connection management and the scalability which IBM provides to the stack are also valuable."

"IBM WebSphere Application Server is the best in terms of scalability and performance, as well as the support for managing distributed transactions."

More IBM WebSphere Application Server pros

"It makes web design easy and quick and gives well finished websites."

"Zend PHP Engine is more secure than any other framework, and I usually prefer Zend PHP Engine for big applications."

"The fact that it is available open-source is the best feature."

"Scaling up is an important factor for large projects, and with PHP 7 and its performance improvements, this becomes even easier."

"We have not encountered issues with scalability as long as we effectively use caching to optimize performance of our web applications as well as a proper use of database connectivity."

"Offers a complete environment to develop PHP applications. It is valuable because it allows you to have a complete stack (PHP, MySQL, Zend Server) enabling the building of a development environment, and to deploy to the production system."

"The Zend Framework provides an easy, open source way to produce coding based on the needs of our customers."

"No issues with stability encountered."

More Zend PHP Engine pros

Cons

"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."

"The installation has room for improvement."

"WebSphere is very cumbersome and not user-friendly. It used to have its own JVM, which presented challenges such as different architecture and memory leaks."

"In spite of the solution's robustness, it is expensive and a bit difficult to support, which is why companies nowadays tend to use more lightweight products such as Tomcat or cloud versions of the products."

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

"The solution consumes hardware."

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

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

More IBM WebSphere Application Server cons

"The biggest problem with PHP is you have to write lot of conditions or have to use a framework."

"SQL queries have always been an issue with PHP, especially if you use large tables, which require caution from the side of the developer."

"The process of installing and configuring the product is a bit complex and could be improved."

"In terms of improvement, it doesn't support concurrent processing. When we want to process anything on a concurrent basis, we have to divide it into a number of things, like a queue, or we have to run it using Cron jobs. We would like to have the capability to run any thread or process in parallel."

"A general scripting language should be further developed and should be embedded into it."

"Zend PHP Engine needs to improve the loading time of its libraries and make it faster."

"Its object oriented programming language needs improvement."

"Integrating AI tools would make PHP more competitive, as other tools already have AI features."

More Zend PHP Engine cons

Pricing and Cost Advice

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

"The solution is quite expensive."

"The licensing cost is 1,000 of euros for a 30-year table."

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

"It's expensive."

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

"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."

More IBM WebSphere Application Server pricing and cost advice

"Zend PHP Engine is not an expensive solution."

"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."

"No problem with pricing and licensing, as tools are open source. You have to consider training cost, mindset setup cost, as part of the TCO."

"The solution is open source and you just pay for the server cost."

"Its pricing depends on the number of users."
