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 possibility of having several servers running, so we do not lose the service."

"WebLogic is reliable, and it's easy to use for development."

"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."

"It is efficient, not redundant, usable, scalable, and meant for enterprise applications."

"The only difference is that Weblogic is lighter and consumes less memory."

"In WebLogic, the most useful feature is the UI administration console from where we can configure everything, such as security access, and we can start and stop it graphically. That's the best feature of WebLogic Server."

"Helps in efficient load distribution"

"It's a very stable solution."
