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.

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."

"Its price can be improved. We are currently looking for more cost-efficiency. It should also have a little bit more flexibility for customizations. The customizations should be quicker."

"One thing that I would like to see is if this product can be containerized. We are moving away from virtual servers and moving more towards containerization to be able to quickly set up environments or have the flexibility of scaling them. It would be good if it can be containerized, and it works well in containerized platforms."

"The main improvement must be made on the user interface. You need to use another Oracle cross in this product. It must be improved and some features of the connectors must be changed."

"The solution's technical support needs to be improved."

"There could be improvements in the installation and integration parts of Oracle Fusion Middleware. The guides often have errors, such as web scripting issues, and can be difficult to follow."

"The documentation might not be good enough for new users."
