2 Key Components to Pivotal Cloud Foundry
• Ops Manager/ Operations Manager: A web application that
you use to deploy and manage a Pivotal Cloud Foundry
PaaS
• Elastic Runtime: The set of core Cloud Foundry services that
are installed, upgraded and scaled via Ops Manager

Orgs, Spaces, Users and Quotas"

Organizations"
Logical division within a Pivotal CF
install / Foundation.
Each organization has its own users
and assigned quota
User permissions / roles are specified
per space within an organization
Sub-divided into Spaces

Quotas and Plans"
Different quota limits (e.g. “small”,
“enterprise”, “default”, “runaway”)
can be assigned per Organization
Quota defines
•  Total Memory
•  Total # of Services
•  Total # of Routes

Spaces"
Logical sub-division within an
organization
Services and Applications are
created / specified per Space
Users authorized at an organization
level can have different roles per
space
Same Service can have different
meanings per space

Platform Monitoring"
How do I know when to scale DEAs?
How many requests each Router is servicing?
What is the current load of my Cloud Controllers?

Pivotal Ops Metrics provides a single
JMX interface to access metrics for
each Pivotal CF component
•  DEAs
•  Cloud Controllers
•  Routers
•  Health Managers
•  NATS, UAA, Login Server, …
