Oracle WebLogic Server needs better integration, microservices support, stability, memory management, customer support, and simpler configurations.

Using scripting allows for the creation of resources.

Oracle WebLogic Server's per-core pricing can be costly, especially compared to free alternatives like JBoss or Tomcat.

Provides integration with Eggplant but problems with stability
We use Windows Server only for Eggplant Manager. Otherwise, I'm not using it   At the moment, we have big problems with stability, and I'm not very happy at the moment. So, the stability could be improved. I have been using it for a few years.  The initial setup is complex.  We have an…
Saikat Nag - PeerSpot reviewer
Offers efficient load distribution with a scope of high scalability
Our organization configures Oracle WebLogic Server in such a way that a load balancer becomes available. The network requests are segregated to the Oracle WebLogic Server as the managing server and different nodes are configured. Using the product as a load balancer helps automate request transfer from one non-functional node to another functional node. Due to Oracle WebLogic Server, the endpoints remain unaffected whenever a node goes down. The clustering feature enhances our organization's performance and reliability. In our organization, the health of the Oracle WebLogic Server environment is maintained and managed using Oracle Enterprise Manager (OEM). I would definitely recommend others to use Oracle WebLogic Server. Overall, I would rate the solution an eight out of ten.
