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.

Offers efficient load distribution with a scope of high scalability

Our organization configures Oracle WebLogic Server in such a way that a load balancer becomes available. The network requests are segregated to the Oracle WebLogic Server as the managing server and different nodes are configured. Using the product as a load balancer helps automate request transfer from one non-functional node to another functional node. Due to Oracle WebLogic Server, the endpoints remain unaffected whenever a node goes down. The clustering feature enhances our organization's performance and reliability. In our organization, the health of the Oracle WebLogic Server environment is maintained and managed using Oracle Enterprise Manager (OEM). I would definitely recommend others to use Oracle WebLogic Server. Overall, I would rate the solution an eight out of ten.

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."

"Helps in efficient load distribution"

"It's a very stable solution."

"Oracle WebLogic Server has a bunch of ready features that are easy to use and understand."

"In the newer system, reconfigurability and the fact that it is easy to configure, make it very valuable."

"Oracle WebLogic Server is secure."

"What I find most valuable in Oracle WebLogic Server is its flexibility in administering and managing applications, along with the built-in dashboards that offer high visibility into vulnerabilities."

"The solution works well in load balancing."

"The technical support is responsive. They are always ready to help by various communication channels, such as Zoom calls. However, sometimes it will take a while because when we are dealing with a problem, they need to look at the logs and configuration. A lot of the issues are related to the configuration that they need to look at thoroughly before they can give us a solution and it can take a few days depending on the type of problem."
