Case Study - Continuous Deployment

Concord is the tool of choice for most continuous deployment needs at Walmart. Rich, powerful pipelines with numerous features are implemented by DevOps teams across the organization.

A simple example flow could be a multi-stage zero downtime deployment of a cloud application:

• Looper CI builds new release binary
• Concord flow is kicked off
• Deployment to QA environment
• Run of a number of tests and verifications on QA
• Slack and email notification to release approvers
• Concord form requires sign in and is used as final manual release gate
• Concord manages zero downtime deployment to production
  • Status changes of multiple clouds
  • Controlled release roll out to clouds
  • Automated smoke test verification
• Final success notifications

Numerous projects at Walmart use this with different deployment cloud platforms including usage of OneOps, Ansible and k8s.
