Oracle Application Database Administrator at RP Sanjiv Goenka Group

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.

Offers high availability, straightforward deployment and easy to use

Tomcat could be a little bit more innovative. Tomcat could come up with a framework that's more lightweight and purely targeted at Java applications. Some other solutions are doing better right now, maybe because they have come up with MicroProfile, which I think is moving forward. It may actually beat Tomcat because of the lightweight nature of the framework, the MicroProfile. They're coming up with new solutions. So, for the future of Tomcat and to maintain the market share they might be looking for, they need to come up with initiatives to ensure that several of us have a lightweight framework to deploy applications on.
