As of April 1, 2017, the cost of the VCDX certification will increase from US$1,200 to US$3,995. Unfortunately for most candidates, this means the VCDX journey will now be an employer sponsored process.
Update: The VMware Education blog post on this subject states that you can purchase a voucher now to be used later and VCDX candidates defending May/June will be charged the current fees. It also mentions prices for “Developing” countries, which is the first I have heard of it, so definitely ask about it.
If you are into HCI, then the zero-fee Nutanix Platform Expert program is also an option.
