This document provides an overview of Cloud Foundry, including: 1. Cloud Foundry is an open source platform as a service that allows developers to build, test, deploy and scale applications. 2. Cloud Foundry uses a distributed architecture that is self-healing with no single point of failure to allow for horizontal scaling. 3. The Cloud Foundry architecture includes layers like the cloud controller, stager, DEA execution agents, services, router, and uses BOSH for automated virtual infrastructure deployment and management of Cloud Foundry clusters.

13. Cloud Controller
• Interfaces with VMC, STS
and Portal
• Rails Application
• Provides Rest Interfaces
for
• Apps
• Services
• Orgs
• Spaces

15. Stager
• Converts the App into a
standard binary
• Uses Pluggin Architecture
• Each Pluggin understands a
Framework or runtime
Thursday, February 21, 13

16. DEA - Execution Agent
• All the Apps run in this
container
• Monitors Apps memory
and disk usage
• Consistent view of the
App irrespective of
runtime
• App Isolation

18. Services
• Interfaces between the
Controller and the Service
Nodes.
• Service Gateway for each
type of Service
• Services deployed in
separate VMs
Thursday, February 21, 13

19. Router
• Responsible for routing
request from outside
world to external facing
components :
• UAA
• Controller
• User Apps in DEA

21. OuterShell : Cloud Foundry
Clusters
• 5000+ VMs
• 40+ unique node types
• 75+ software packages
• 24/7 Operations
• No downtimes

25. Cloud Provider Interface
• Provides abstraction to the
Infrastructure
• Implementation for
vSphere, OpenStack and
AWS
• Pluggable architecture
allows other stack to be
added like vCloud

26. Deployment on vSphere
Thursday, February 21, 13

27. Steps to Deploy on
vSphere
1. Setup the Hardware -
1.1.ESXi boxes, vCenter, SAN based Storage, Private
Network with L2 / L3 Switch
1.2.Domain Name Server
2. Install Bosh CLI
3. Install Micro Bosh
4. Use Micro Bosh to Install Bosh - 6 VMs
5. Use Bosh to Install Cloud Foundry - 49 VMs

28. Summary
• Cloud Foundry is a Polyglot Open Source Paas
• Can be run on Public or Private Cloud
• It is Iaas agnostic : Supports vSphere, AWS,
OpenStack
• Avoids vendor lock-in
