Google recently started the Credential Holder Directory initiative for Google Cloud Certified Professionals. Google Cloud Certifications are around for a while, but Google didn’t have a centralized listing of certified professionals in the past. With the Credential Holder Directory initiative, Google gives an option for professionals to maintain their own personal directories with all relevant certifications.
At the time of this writing, there are about 2000 professionals listed in the Directory, covering handful of certifications offered by Google Cloud Platform. That number is going to grow within a short time. One good feature of this directory is that each professional can maintain a short profile and links to Twitter and LinkedIn, along with all Google Cloud Certifications the person holds.
