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
instances – this is where
things get pushed live
