Figure 5-2. Complete cloud lifecycle
EM12c helps you manage the entire cloud lifecycle from a single tool. Let's look at the phases of this lifecycle in
more detail.
Planning the Cloud
Moving to the cloud from your existing IT infrastructure is transformational in nature. It requires extensive planning to
consider various design and operational criteria for successful deployment and operation of the cloud infrastructure.
First, you need to determine all the applications and infrastructure assets in the environment. You also need
to understand the relationships between them so you can decide what to keep as is, what to update, and what to
retire. Consolidating your applications and underlying infrastructure before, or as part of, moving to the cloud is
considered an industry best practice. Over the years, data centers have accumulated excess servers that occupy rack
space, consume a lot of power for cooling, and require system maintenance such as patching, and many of them are
underutilized.
EM12c provides automated capabilities that allow IT departments to discover existing applications and
infrastructure assets along with the relationships between them. This blueprint of the data center provides a baseline
for cloud transformation planning. Additionally, EM12c offers a tool called Consolidation Planner, discussed in detail
later in this chapter, that can simulate various consolidation scenarios based on usage data stored in OEM's repository
and projected capabilities of future consolidation platforms. In the example shown in Figure 5-3 , databases running
on seven servers are being analyzed for consolidation to a quarter rack of Oracle Exadata.
