In-Depth Information
The cloud admin (the administrator of the cloud infrastructure) monitors the health of the overall cloud
application-to-disk stack by using Oracle Enterprise Manager to track resource flux, tenants, policy violations,
and other incidents. The Oracle Enterprise Manager Incident Manager, shown in Figure
5-12
, provides cloud
administrators with a single interface that can be used to view, manage, resolve, and track all types of issues that have
occurred within their monitored environments. Incident Manager is covered in more detail in Chapter 12.

In addition, the cloud administrator performs ongoing monitoring of requests and failure rates and identifies
potential performance bottlenecks to remediate. Cloud administrators can automatically monitor cloud targets by
using an administration group that defines dynamic criteria to group together cloud targets and auto-assign monitoring
settings and policies. These groups can be created based on properties such as location, department, test, or production.
Self-service admins, who administer the common resources used by application owners at the line of businesses,
monitor the application stack, the service levels and dependencies on the infrastructure, the end-user experience,
and many other areas.
Self-service users or application owners monitor the health and quota aspects for their own applications hosted
in the cloud environment. They can perform basic monitoring of provisioned resources including virtual machines,
hosts, and databases. They can also monitor the end-user application experience.
Chapter 7 provides more details and best practices for the monitoring and management phases.
Managing the Cloud
You just learned about cloud monitoring, which is a process of being aware of the state of the applications and underlying
cloud infrastructure. Monitoring typically results in uncorrelated sets of data.
Cloud management
is a set of functionalities
and processes that use this data to deliver a desired objective for the cloud infrastructure and the applications deployed
in the cloud. It involves managing and allocating cloud resources to produce useful outcomes.
EM12c provides comprehensive cloud stack management and business-driven application management
functionalities. The Enterprise Manager approach is to move away from bolt-on and piecemeal management; embed
management into the core solution; and deliver a complete, unified, and integrated solution for managing the entire
stack. With EM12c, you have a single point of control for the entire infrastructure stack, including performance
management, configuration management, and automated lifecycle operations such as provisioning and patching.
