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

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

"As compared to other applications, it has tremendous support. We have built internal capability so that we use it extensively internally. It is also easier to use with the outside data. You can write in ESQL, Java, or any other technology that you want to use for development. So, it is a lot more flexible in the language that it supports."

"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."

"The most valuable features are its user-friendliness and reliability in terms of application hosting."

"IBM WebSphere Application Server is easy to use."

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

"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."

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

More IBM WebSphere Application Server pros

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

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

"Essentially, we get the best performance at very affordable costing."

"This solution is really easy for me to use."

"Zend Engine is the core of PHP. It makes PHP fast, efficient, and basically, the language of choice for web applications."

"It offers good support for various types of classes, along with many open source libraries that we can readily utilize in our application development process. This gives us a lot of options when it comes to custom development solutions, without having to worry about licensing or other programming-related issues."

"Zend Engine gives the flexibility to use external modules to easily expand the functionalities you need for your web project."

"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."

More Zend PHP Engine pros

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."

"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."

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

"The support could be a bit more responsive."

"The solution could improve the integration."

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

"The main issue we faced was its limited compatibility with non-Java technologies, which can result in difficulty detecting potential bugs and requiring additional integration efforts."

"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)."

More IBM WebSphere Application Server cons

"The platform is not satisfying to me -- it is just not up to standards performance wise."

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

"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."

"Its object oriented programming language needs improvement."

"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."

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

"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."

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

"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."

"We pay around $200,000 annually."

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

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

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

"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."

More IBM WebSphere Application Server pricing and cost advice

"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."

"Its pricing depends on the number of users."

"Zend PHP Engine is not an expensive solution."

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