VMware Certified Design Expert (VCDX) is the highest level of certification offered by VMware. The VCDX Program allows candidates to validate enterprise-class skills in VMware Solution design and implementation. Certification is achieved through the Design Defense where all candidates must submit and successfully defend a production-ready VMware Solution before a panel of veteran VCDX-holders. This unique testing process ensures that those who achieve VCDX are peer-vetted and ready to join an elite group of world-class consulting architects.

VMware Certified Design Experts are part of an elite group of architects leading virtualization implementations around the world. Join this community of experts by earning your VCDX certification for Datacenter Virtualization, Cloud, or Desktop.
