When you deploy Cloud Foundry the

following sequence of steps occur:

1.  Target a BOSH director using CLI

2.  Upload a Stemcell

3.  Get a Release from a repo

4.  Create a deployment manifest

5.  BOSH Deploy Cloud Foundry:

• Prepare deployment

• Compile packages

• Create and bind VMs

• Pull in job configurations

• Create needed job
