Taking Pivotal Cloud Foundry Small Footprint for a test drive

Pivotal Cloud Foundry (PCF) now has a small footprint edition. It features a deployment configuration with as few as 6 VMs. Review the documentation for download and installation instructions as follows

There was also a Pivotal blog post on this as follows:

As you can see from this image it's considerably smaller control plane that's obvious.

It is important to understand what the limitations of such an install are as per the docs link below.

Installing the small footprint looks identical from the Operations Manager UI in fact it's still labelled ERT and from the home page of Operations Manager UI your wouldn't even know you had the small footprint

If you dig a bit further and click on the "ERT tile" and then select "Resource Config" left hand link you will then clearly know it's the Small Footprint PCF install.

I choose to use internal MySQL database and if I didn't then it could be scaled back even more then the default 7 VM's I ended up with.

Lastly I was very curious to find out what jobs are placed on which service VM's. Here is what it looked like for me when I logged into bosh director and run some bosh CLI commands
ubuntu@ip-10-0-0-241:~$ bosh2 -e aws vms --column=Instance --column="Process State" --column=AZ --column="VM Type"
Using environment '' as user 'director' (bosh.*.read, openid, bosh.*.admin,, bosh.admin)
