This can be further expanded upon to also include availability monitoring of the other vCloud components, however this can also be achieved simply by having all these vCloud Management VMs running in a Management Cluster vCenter as per the vCloud Architecture Toolkit and using a vCenter […]
Taking on a new challenge
After two years at VMware working in the Centre of Excellence (CoE) I can now officially announce that I will be starting a new role in April. I will be staying in Global Technology Solutions (GTS), but moving over to the Solutions and Services Engineering team working as a Senior Solutions Architect.

This is going to be another exciting challenge, working with new people (most of whom I already know). I have loved my time in the CoE (and made some really good friends), so it is with a heavy heart I am leaving. However I will not be moving far staying in […]
