Cloud Foundry High Level Usage
Here is my source code, run it on the cloud for me, I don’t care how.

Tenancy Management
Logical isolation
• Cloud Foundry supports
organizations for tenancy
management
• Organizations contain spaces
that further divides the
organization
• Organization can be limited with
quotas and billed based on their
usage

Organisations
Logical isolation
• Organisations have users with
different roles: Manager / Billing
Manager / Auditor
• Organization can have quotas
assigned that limits the total
resource consumption
• Organizations can be self-
maintained by the organization
admin

Spaces
Logical isolation
• Spaces have users with different
roles: Manager, Developer,
Auditor
• Spaces can have additional
quotas assigned that limit the
total resource consumption
• Services and applications are
scoped to a space

stage Droplet
cf push store
• Add frameworks, libraries and runtimes
• Add APM tools
• Put certificates in place
• Configure security
• Optimize runtime (e.g. memory flags)

Scaling
Horizontal or vertical
• Applications can be horizontally
scaled out with more instances
(without down-time and
recommended)
• Applications can be vertically scaled
up with more memory / disk space
• Pivotal CF auto-scaler can
automatically scale based on CPU
load
20

Logging & Monitoring
Insights for your app
• Cloud Foundry supports the collection of all logs
and metrics (components, apps) into a unified
stream
• Logs can be retrieved from the platform via
Ø Command Line
Ø Syslog
Ø 3rd Party Systems (e.g. Datadog, Instana)

Services
24

Services
Self-service for spicing up your app with services
• Cloud Foundry provides a service abstraction for service
providers and consumer applications
• Service Broker provides possibility to provision services (e.g.
persistent services) through a centralized API
• Application can use the services by inspecting the environment
variable VCAP_SERVICES
25

Marketplace
Offers a wide variety of different services
• Services can be registered in
the marketplace (either
manually or during
installation with bosh)
• Services can offer service
plans (e.g. 1 GB, 10 GB,
dedicated)
• Administrator can configure
service plans
26

Open Service Broker API
Integrate any service
27
• Open API
specification to
provision and bind
service instances
• Platform-agnostic to
foster reuse of
service broker
implementations
across different
platforms.
