Dealing with Availability and Recoverability requirements in a VCDX design
I’m going to take a big risk here by trying to address the topics Availability and Recoverability in a VCDX design. This is arguably both the most important and most challenging topic of any VCDX design. I would say VCDX candidates get grilled on meeting SLAs, RPO and RTO times the most during the mocks ...

Finally … VCDX6-NV and Double VCDX! A reflection

How to delete protected NSX-T objects created by PKS
In my previous blogpost, I explained how to remove a failed PKS cluster by removing the BOSH deployment using the BOSH CLI. Removing the BOSH deployment does not remove the NSX-T objects however. Manually deleting these NSX-T objects using the GUI is prohibited because these objects are supposed to be managed by PKS and are ...
How to delete a failed PKS Cluster using the BOSH CLI
UPDATE: I received some feedback on this blogpost from some of my ITQ colleagues.

This is easily fixed by Bosh by applying changes ...
