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 e-Business Suite may soon be sunsetted and has an outdated UI, with few upgrades.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."
"On the whole, if you are looking for one product that is flexible, easy to use, and versatile for many different scenarios, then I would definitely recommend Oracle Fusion Middleware."
"Fusion Middleware's main feature for me is that it is quite flexible, and, as middleware, it provides us with all sorts of technology and application adapters, which makes it very handy to use."
"The solution is extendable so you can start with two cores and add more at any time."
"The most valuable features are Oracle Unified Directory and unified identity access management."
"I rate Oracle Fusion Middleware as ten out of ten."
"This solution has improved the way our organization functions because it does the issuing of BOs, purchasing orders, purchasing requests, and we monitor the cost for projects on it, and we use it for making the payroll for employees."
"The solution is very easy to install."
"It is really good in terms of features, and it is stable."
 

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."
"Oracle Fusion Middleware is based on the regulations in Saudi Arabia and the legislation changes. There is a need to be improvements all the time. It needs to adapt quickly in this market. Additionally, there could be some improvements in the construction sector."
"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."
"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."
"An improvement for Oracle's Fusion Middleware could definitely be found in the SOA component. It's a heavyweight container and, if you ask me, if a product is available as a docker image where we can easily port it in to another Kubernetes platform, that would be perfect. But as for the current situation in the market, nobody is really willing to deploy this on premises."
"The product should improve BPEL features."
"The documentation might not be good enough for new users."
"The price could always be better."
"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."
 

Pricing and Cost Advice

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