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.

The fact that it is available open-source is the best feature
The fact that it is available open-source is the best feature.  A general scripting language should be further developed and should be embedded into it. I have been Zend PHP Engine for nine years.  Multiple people are using the solution.  Overall, I rate the solution a seven out of ten.…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product offers good performance."
"This solution is easy to use with a GUI that is intuitive and very helpful."
"The solution has good performance."
"The scalability of the product is quite good."
"Ease of administration: It has an Integrated Solutions Console, what we call the administrative console, with very detailed configurations and Help pages for each configurable item."
"Starting with version 8, WAS provides a special folder called monitor deployment. Once you put the .war or .ear file in there, it is deployed automatically without human intervention. This greatly helps us in our continuous integration server. Once the deployment binary is ready, we write a script to copy it to that folder and then, voila! The application is up and running and accessible from its context root."
"IBM WebSphere Application Server is the ultimate product; there is nothing superior to IBM WebSphere Application Server, and while there are other options such as Tomcat, JBoss, and Oracle's solution, IBM WebSphere Application Server stands above them all."
"IBM WebSphere Application Server is one of the best servers due to its stability and paid license."
"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 solution's initial setup process is easy."
"The cache modules that Zend provides have been able to optimize and accelerate the loading of the pages when there was exponential growth in data volume and quantity of requests. At the same time, the monitoring console allowed us to have a real-time understanding of the resources and to make decisions when they were at the limit."
"​Zend Engine is the core of PHP. It makes PHP fast, efficient, and basically, the language of choice for web applications."
"The Zend Framework provides an easy, open source way to produce coding based on the needs of our customers.​"
"Zend Engine gives the flexibility to use external modules to easily expand the functionalities you need for your web project."
"Zend PHP Engine is more secure than any other framework, and I usually prefer Zend PHP Engine for big applications."
"This solution is really easy for me to use."
 

Cons

"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."
"Based on the field and based on the build that was provided, we've noticed a lot of constraints in terms of the performance now."
"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."
"The installation has room for improvement."
"Installing or configuring a WAS server instance as a Windows Service causes a lot of problems, especially when the server needs credentials to stop."
"In the next release of this solution, I would like to see support for the Arabic language."
"When compared with WebLogic, Weblogic is lighter and consumes less memory."
"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."
"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."
"The solution can be quicker."
"Although it offers a complete environment to develop and deploy PHP applications, it has some limitations. For example, when the volume of data increased exponentially, I had problems scaling the system."
"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.​"
"Integration of MVC with ORM tools for PHP is okay, but lacking a short list of decent ORM tools for PHP to choose from; there is ample room for improvement in both areas."
"Zend PHP Engine needs to improve the loading time of its libraries and make it faster."
"The main area that Zend needs to improve is to support asynchronous programming tasks, which is facilitated in PHP 7, but not at the same degree as HHVM.​​"
 

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."
"We pay around $200,000 annually."
"It's expensive."
"There is an Eclipse Plugin provided by IBM, so no need to buy IBM Rational Application Developer or Rational Software Architect tools."
"The licensing policy is based on the PVU base."
"The solution is quite expensive."
"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."
"The licensing cost is 1,000 of euros for a 30-year table."
"Its pricing depends on the number of users."
"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."
"The solution is open source and you just pay for the server cost."
"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."
"Zend PHP Engine is not an expensive solution."
