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.

Migration to a modern interface enhances AI integration and cloud capabilities
Presently, Oracle recommends migrating to Oracle Fusion since it's a hot product now. e-Business Suite may soon be sunsetted and has an outdated UI, with few upgrades. In contrast, Oracle Fusion offers modern features, such as AI, cloud-based applications, and customization options like Redwood features. Oracle Fusion AI chatbots are embedded, benefiting projects.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a stable solution compared to other vendors."
"The flexibility to create different services in different environments using IBM Open Liberty was important."
"The scalability is good."
"We can advise any enterprise organization to use this product because you can trust this product."
"The solution is very easy to install."
"One good thing, which is a little bit common across all middleware products, is that you can build asynchronous as well as synchronous processes. The SOA part is where it can maintain your state for any state-full integrations. If you have failures, you can replay all that, which is a good part."
"Oracle Service Bus is the most valuable feature of the solution."
"The solution is extendable so you can start with two cores and add more at any time."
"It's like an umbrella under which we're using a group of products."
"The initial setup is easy. There are many self-tutorial videos are on the Internet, and then the Oracle documents are self-explanatory."
 

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."
"The product should improve BPEL features."
"An improvement for Oracle's Fusion Middleware could definitely be found in the SOA component."
"For improvements, I think Oracle Fusion Middleware could be better at connecting to third-party applications. While it works well with Oracle products, it's more limited to non-Oracle systems than other middleware solutions like MuleSoft."
"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 price could always be better."
"The solution's technical support needs to be improved."
"Oracle rapidly releases new features, and I may not be ready to adopt them."
"The main improvement must be made on the user interface."
 

Pricing and Cost Advice

"It is less costly than one of its competitors."
"The tool is best suited for large companies due to high licensing costs."
"It is expensive. We are looking for a cheaper solution."
"The licensing costs are reasonable."
"My advice is to buy the basic modules first, gain the most benefit from them, then buy the advanced modules."
"The solution is quite expensive so is only used by larger organizations."
"The pricing is moderate. It's fine."
"We pay annually for the solution."
"The solution is expensive so pricing is rated a six out of ten."
