Has enabled flexible deployment of modular services with high availability and smooth dynamic updates
The best features of IBM Open Liberty are the implementation of MicroProfile and Jakarta EE, along with fault tolerance and high availability. It's easy to use and deploy new features. The profile is easy to configure and set up features. For example, using fault tolerance from MicroProfile or using servlets or JAX-RS allows for easy configuration and creation of modular applications. The configuration is modular. The main point for us in this project was high availability, high performance, and the implementation of MicroProfile and Jakarta EE. We utilized the modular architecture of IBM Open Liberty by creating different microservices using different environments. We created different configurations for different services using the configuration of IBM Open Liberty. This was very beneficial. We created different environments only by changing the configuration, depending on the functionality we needed. It was good and very flexible for us. I used the dynamic updates feature of IBM Open Liberty and different configurations in different services and servers, based on the functionality we provided for our clients. The flexibility to create different services in different environments using IBM Open Liberty was important. The high availability is guaranteed by the architecture of IBM Open Liberty, Java, and MicroProfile. The architecture guaranteed high availability, and the flexibility comes from being able to configure needed features. There's no need to load all WebSphere or functionalities in all environments. I can configure it and create a more highly available and scalable process. I implemented monitoring tools for IBM Open Liberty using Grafana and OpenTracing using the functionalities from MicroProfile and IBM Open Liberty. The monitoring tools helped with managing system performance.

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.

Pros

"The flexibility to create different services in different environments using IBM Open Liberty was important."
"It is a stable solution compared to other vendors."
"IBM WebSphere Application Server is easy to use."
"Security: It is compatible with the latest Java 8 security features, supports FIPS 140-2 and NIST SP 800-53 with strong ciphers and cryptography keys, and supports TLS 1.2 completely. Also, configuring client and server certificates is relatively easy."
"It does integrate well with the Tivoli Federated Identity Management system."
"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."
"WebSphere Application Server's best features include the data subscription and connection viewer."
"We needed this type of integration and WebShepere is the best tool for it."
"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."
 

Cons

"Its support documentation could have detailed information on database integration."
"To improve IBM Open Liberty, more integration with Kafka and message systems, and asynchronous messaging would be beneficial."
"Sometimes, I feel WebSphere runs a bit slow. It might be loading unnecessary libraries, impacting its performance compared to other application servers."
"The availability of the solution needs improvement."
"The current trend is to move to Liberty because of the portability of its cloud and its Kubernetes, which containerize the application."
"They should make the solution more lightweight and not bundle everything into a single product."
"What could be improved in IBM WebSphere Application Server is its interconnection with other products, for example, Kafka. What I'd like to see in the next release of the solution is a better graphical user interface."
"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."
"WebSphere Application Server doesn't have an automated deployment option, forcing us to use third-party tools like Jenkins UCD and Palo Automated Deployment."
"In spite of the solution's robustness, it is expensive and a bit difficult to support."
 

Pricing and Cost Advice

"It is less costly than one of its competitors."
"The price of this product is higher than that of competitors."
"It's expensive."
"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"IBM WAS base is part of the deal when you purchase IBM FileNet P8 Content Engine."
"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."
"When you purchase Maximo, you get WebSphere for free."
"WebSphere Application Server is expensive, so it may not be a good option for small companies."
"It is very expensive."
