Continuous Delivery in 2015
Development
• Commit• Merge• Trigger pipeline
Build
• Create artifact• Assign version
Testing
• Journey across environments• Quality criteria
Production
• Canary deployment• Release != deployment
Continuous Delivery in 2015
Development
• Commit• Merge• Trigger pipeline
Build
• Create artifact• Assign version
Infrastructure
• Infrastructure as a code• Automated• On-demand
Testing
• Journey across environments
• Quality criteria
Production
• Canary deployment• Release != deployment
Declarative vs Imperative
Declarative• I want this server in this state
Imperative• I want you to apply this sequence of actions
Mutable (reusable) vs Immutable (disposable)Reusable• I want to use the same server during the life of the project.
Immutable • I want to provision a new server when I need to change something.

Case 1
Challenges• Projects require environments to be created• A lot of environments are similar• Takes time for admins to provision and configure them
Private cloud enables automation
What we did• VMware vSphere to provide on-demand VMs• Puppet to configure environments• Hiera to separate data from the code• Jenkins to control the lifecycle
Continuous Delivery• Huge time savings and code reuse• Developers are enabled to create configurations• Deployments are scripted

Challenges• Control the state of the environments• Release new versions of applications safely• Automate the procedures to save time
Case 2
What we did• Puppet to control the state of the servers• Package artifact and assign version• Deploy specific version to specific environment• Rebuild the whole environment on deploy
Continuous Delivery• Visibility• Repeatable process• Scripted deployments

Case 3
Challenge• Software needs to be tested in different configurations• Test environments are multi-server• Environments take days to provision manually
Environments as a service
Solution• Amazon Web Services to provision infrastructure• Ansible to create procedures for each configuration• REST API service to coordinate requests
Continuous Delivery • Ready for both human and robots • 20 minutes to create any environment• Reduced feedback time
