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.

Stable and scalable enterprise deployment with Cloud-Native support

Oracle WebLogic Server helps with my deployment strategy in both monolithic as well as Cloud-Native ways. I think it is useful; this Cloud-Native support helps with deployment in both on-prem and cloud. For container deployment, we are not very rich. We are in the process of moving our business logic to containerization. But in terms of this being a big product, a core banking system, I prefer on-prem rather than cloud. The use cases and the scrum help me a lot in an iterative, incremental manner. I would recommend this product; it is an enterprise, large volume, and of course, it is worth it to deploy. I am providing this review with a rating of 9.
