• Enterprise Manager 12c comes with an out-of-box self-service application that lets end-users deploy a wide range of these services.
End users can choose to manage and monitor all applications along with databases and platforms/OS, all in an on-demand fashion. For each request, they can specify the amount of underlying resources (CPU, memory, etc.) that they require for each component.
• Enterprise Manager automatically provisions the requested service and the appropriate resources. The self-service application also lets users define policies to scale out or scale back resources based on schedule or performance metrics.
For example, one can set a policy to elastically scale out a web server if the processor load on existing web servers exceeds a certain threshold value.
• It allows management of sophisticated Oracle applications, like Oracle E-Business, Siebel, and PeopleSoft, aiding in many administrative activities of these apps, like real user monitoring of any web application.• Enterprise Manager 12c has the ability to define contractual Service Level Agreements (SLAs) that govern the contract between the application owner and the provider of the Cloud. Administrators, as well as users, can also define management policies that automatically adjust the service resources, to ensure that SLAs are met.• Enterprise Manager enables the application for the end-user via a self-service interface, both in graphical (GUI) .
Room for Improvement:
The only con is that we may need to install patches provided by Oracle from time to time for its upgrades or bug fixes. This is an activity that occurs quite frequently.

It offers a simple scalable solution for running Oracle applications. It enables you to manage everything in your datacenter, from the hypervisor to the operating system, database, and application tier. I have used this technology for quite a long time and found that Oracle Enterprise Manager is the industry’s first solution that has the ability model, not only infrastructure as- a-service (IaaS), but also platform-as-a-service and database-as-a-service Clouds, from a single console.
The extent of usage of Oracle Enterprise Manager depends upon nature & the size of the organization and management’s concerns. However, Oracle Enterprise Manager provides a full board of controlling & monitoring as per your needs.
