I was lucky enough to be on VUPaaS recently. It is hosted by GS Khalsa, Josh Atwell and Chris Wahl. I have found it very useful for hearing about how other customers are using virtualisation and cloud automation technologies to solve their operational issues and then applying those lessons within my own organisation. This series of podcasts was also a very important part of my VCDX preparation, particularly in developing use-cases and alternate design scenarios for my defence.
So if you have not subscribed to the show on iTunes, then you should do yourself a favour and give it a go!
