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.

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."

"It has helped us to have different clusters within different servers, which allows us to identify hacker attacks."

"Oracle WebLogic Server is a stable product."

"There are many valuable features in Oracle WebLogic Server, for sure, production redeployment is one of the best in order to deploy the new version of your application without removing the old one."

"We've got the support we require. If ever there is an issue, can just call on Oracle and they will assist us."

"It is good because it's easy to use. It doesn't crash frequently like other servers."

"I would rate Oracle WebLogic Server nine out of ten, possibly even ten points."

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

"The tool's technical support is very good."

More Oracle WebLogic Server pros

Cons

"To improve IBM Open Liberty, more integration with Kafka and message systems, and asynchronous messaging would be beneficial."

"Its support documentation could have detailed information on database integration."

"The solution is very expensive, and its pricing could be improved."

"Managing and monitoring the WebLogic server environment has been challenging because most monitoring tools don't support it."

"There are always ways to improve."

"In terms of what could be improved, maybe something related to the processes automation or starting and stopping the processes, because often WebLogic comes with something called Node Manager. Node Manager needs to be configured and administrated manually."

"Licensing fees need improvement."

"Having clearer mechanisms to directly map a database-level connection problem to the corresponding WebLogic thread would greatly enhance the administrator's convenience."

"The tool's implementation should be easier. The product is also expensive."

"The logs consultant, since it tends to be more in the server, we do need complete consult logs for a lot of different files."

More Oracle WebLogic Server cons

Pricing and Cost Advice

"It is less costly than one of its competitors."

"Fees are paid on a yearly basis."

"The licensing of the product is expensive"

"I would not compare WebSphere and WebLogic because both servers are really good. The only difference is that Weblogic is lighter and consumes less memory."

"The tool's pricing is yearly."

"It is expensive."

"Its high expense is a significant drawback"

"The solution's licensing is high-priced."

"The solution’s pricing is affordable."
