Let’s take a closer look at how Spinnaker works:

# Example Spinnaker pipeline configuration
pipelines:
  - name: Deploy to Production
    stages:
      - type: bake
        name: Bake AMI
        baseOs: ubuntu
        baseLabel: release
      - type: deploy
        name: Deploy to Cluster
        clusters:
          - account: prod
            application: myapp
            strategy: red-black
            capacity: 
              desired: 2
              min: 1
              max: 3

This YAML configuration defines a simple pipeline that bakes an Amazon Machine Image (AMI) and deploys it using a red-black (blue-green) strategy, ensuring zero-downtime deployments.

4. Developing internal tools that later evolved into AWS services

One of the key tools in Amazon’s DevOps arsenal is AWS CodePipeline. Here’s a simple example of how it can be configured:

{
  "pipeline": {
    "name": "MyFirstPipeline",
    "roleArn": "arn:aws:iam::123456789012:role/AWSCodePipelineServiceRole-us-east-1-MyFirstPipeline",
    "stages": [
      {
        "name": "Source",
        "actions": [
          {
            "name": "Source",
            "actionTypeId": {
              "category": "Source",
              "owner": "AWS",
              "provider": "CodeCommit",
              "version": "1"
            },
            "configuration": {
              "RepositoryName": "MyCodeRepo",
              "BranchName": "main"
            },
            "outputArtifacts": [
              {
                "name": "SourceArtifact"
              }
            ]
          }
        ]
      },
      {
        "name": "Build",
        "actions": [
          {
            "name": "Build",
            "actionTypeId": {
              "category": "Build",
              "owner": "AWS",
              "provider": "CodeBuild",
              "version": "1"
            },
            "configuration": {
              "ProjectName": "MyBuildProject"
            },
            "inputArtifacts": [
              {
                "name": "SourceArtifact"
              }
            ],
            "outputArtifacts": [
              {
                "name": "BuildArtifact"
              }
            ]
          }
        ]
      }
    ]
  }
}

This JSON configuration defines a simple pipeline that pulls code from a CodeCommit repository and runs a build process using CodeBuild.

Etsy’s DevOps journey focused on three key areas:

1. Continuous Deployment: Implementing tools and practices to deploy code multiple times a day
2. Monitoring and Observability: Developing robust systems to track performance and quickly identify issues
3. Blameless Post-Mortems: Fostering a culture of learning from failures without pointing fingers

One of the tools Etsy developed to support their DevOps practices is Deployinator, a deployment dashboard that makes it easy for any engineer to deploy code. Here’s a simplified example of how Deployinator might be configured:

# Example Deployinator configuration
Deployinator.app do
  # Define your stacks
  stack "web" do
    # Define deployment steps
    run "bundle install"
    run "rake db:migrate"
    run "restart_web_servers"
  end

  stack "background_jobs" do
    run "bundle install"
    run "restart_workers"
  end

  # Define hooks
  before_deploy do
    notify_team
  end

  after_deploy do
    run_smoke_tests
  end
end

This Ruby-based configuration defines deployment steps for different parts of the application and includes hooks for notifications and post-deployment checks.

The Results:
Etsy’s DevOps transformation led to remarkable improvements:

• Deployment frequency increased from twice a week to over 50 times a day
• Mean time to recovery decreased significantly
• Employee satisfaction improved as the fear of deployments dissipated
