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.

Quotes from Members

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

Pros

"The products offers EE support."
"The only difference is that Weblogic is lighter and consumes less memory."
"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."
"Another valuable feature is the ability to automate tasks through scripts, making our environment highly efficient."
"Helps in efficient load distribution"
"WebLogic initial cost (acquisition and implementation) is relatively expensive, but I believe it's worth its price and the long-term benefits are enormous."
"The biggest benefit I see from Oracle WebLogic Server is that it is beneficial; we are stable through a large volume of transactions, I am able to have a highly scalable, highly demanding, enterprise deployment, and I am able to increase the volume based on the demand."
"The product's installation phase is easy."
"WebLogic is a mature Java application server and when compared to competitors, it excels in speed, scalability and stability."
 

Cons

"I would like to see integration with MQ systems."
"The tool's implementation should be easier. The product is also expensive."
"Licensing fees need improvement."
"There are always ways to improve."
"I'd like to have a lighter version for micro-service architecture. In my experience, it can sometimes take 15-30 minutes just to start the server if we deploy a lot of applications."
"We're now using a binary WebLogic server without coherence so the in-memory replication we are operating, sometimes fail."
"The full license is costly."
"They should improve the solution's garbage collection feature."
"Stability was an issue in earlier versions, it was sometimes difficult to bring up the server whenever it goes down, which seldom happens."
