Is there any certification for DevOps?

I am interested in getting stronger in DevOps,

and what better guidance than a certification preparation to muscle up in DevOps.

Ops is a wide topic.

• Here a list of some "official" certification programs.
• Amazon Web Services certification
• Microsoft Azure certification
• Google Cloud Certifications
• Chef certification
• Ansible Certification
• Saltstack Certification
• Puppet Certification
• Jenkins Certification
• Nginx Certification
• Docker Certification
• Kubernetes Certification
• OpenShift Certification
• Splunk Certification
• AppDynamics Certification
• NewRelic Certification
• Dynatrace Certification
• Elastic Certification
• Pivotal Cloud Foundry Certification
• Atlassian Certification - Jira & Confluence
• Apache Kafka Developer Certification | Confluent
• PagerDuty Course
• signalfx
• HashiCorp - Terraform Certification

It's quite a long list, and each item is deep.

I think having an introductory knowledge of each would be nice,

and an extensive understanding of one or two of these would be fair.
