- 28. What are some strategies for Continuous Delivery?
- 29. The Continuum of Strategies for Continuous Delivery Continuous Delivery - Enabling organizations to roll-out frequent updates of applications to address business needs while minimizing risk of disruptions. Application delivery is a spectrum… Where are you on it? Manual Delivery Basic Automated Delivery Blue-Green Delivery Dynamic Delivery
- 30. Delivery Strategies: Manual Delivery Approach • Build an app package with latest updates – Perhaps via a CI process • Deployments are rollups of small and large changes • Use a maintenance window to turn app off during upgrade • Staff pushes app updates onto live servers from their own machines Risks • Time to delivery – Are you getting enhancements deployed regularly? • Integrity – How do you know what got pushed and where it came from? • Reproducibility – How if you need to reproduce this version later, how can you do it? • Reliability – Humans are involved, so mistakes will (eventually) happen My developers are pushing things live from their boxes – I’m terrified all the time
- 31. Delivery Strategies: Basic Automated Delivery Approach • Use a CI system for building and testing packages – Jenkins • Use a maintenance window to turn app off during upgrade • Use automation scripts to update primary application environment – Chef, Puppet or custom scripts Advantages • Deploy faster and with better reliability and repeatability Considerations • History - How do you track what got pushed and where it came from? • Verification - How do you know the application is working properly? • Disruption - How long are apps down for maintenance? • Rollbacks - How do you revert back to a known working version? We’ve automated our deployments, but we struggle with downtime and rollbacks
- 32. Delivery Strategies: Blue-Green Delivery Approach • Avoid maintenance windows by maintaining separate primary and secondary app environments • Use automation to upgrade secondary environment • After verification, secondary is promoted to primary • Old primary is demoted to secondary – stays around as last-known-good environment Advantages • Seamless updates with verifications • Rollbacks are simple – just switch the primary back to the secondary Considerations • History - How do you track what got pushed and where it came from? • Maintenance – How do keep two long-running app environments up and stable? Our delivery is automated and supports pushing + verifying deployments to long- running environments with easy rollbacks
- 33. Delivery Strategies: Dynamic Delivery Approach • Use CI to produce app packages • Provision new application environment as part of delivery • Run verification tests against the new environment • Promote the new environment to become the primary environment Advantages • Seamless updates with verifications • Rollbacks are simple – just switch the primary back to the secondary • Reliably reproducible app environment Considerations • History - How do you track what got pushed and where it came from? • Requires cloud-like provisioning layer Our delivery is automated end-to-end, including setting up new Cloud environments or using Configuration-in-Code and full verification before changes go live

- 41. How Can CloudBees Jenkins Enterprise Help with Your CD Strategy? Jenkins Workflow Created by CloudBees to provide Jenkins with a way to define flexible delivery pipelines that allow for a rich set of new delivery scenarios Deployment History Tracking • Track the history of your deployments – including who kicked off a deployment and what code changes were included in it Deployment Verification • Create pipelines that leverage verification tests to determine the quality of a new deployment Automated Rollbacks • Define rollback strategies to handle cases where deployment verification fails Blue-Green Deployments • Leverage the power of workflow to coordinate zero-downtime deployments Dynamic Environment Creation • Spin up new deployment environments automatically as part of your delivery pipeline.

- 43. How can the CloudBees Jenkins Enterprise help? Workflow Stage View • Provides deep insight into the execution of your workflow stages so you can detect problems and performance issues Restart deployments where they break • Leverage workflow checkpoints to restart delivery pipelines without a full (expensive) rebuild Cluster Operations • Separate building from delivery, and coordinate job execution across multiple Jenkins masters Jenkins Analytics • Monitor and analyze performance across all your Jenkins instances
