Chapter 9. Advanced Continuous Delivery
In the last chapter, we covered how server clustering works and how we can use it together with Docker and Jenkins. In this chapter, we will see a mixture of different aspects that are very important in the Continuous Delivery process but have not been described yet.
This chapter covers the following points:
- Explaining how to approach database changes in the context of Continuous Delivery
- Introducing the idea of database migration and related tools
- Exploring different approaches to backwards-compatible and backwards-incompatible database updates
- Using parallel steps in the Jenkins pipeline
- Creating a Jenkins shared library
- Presenting a way to roll back production changes
- Introducing Continuous Delivery for legacy systems
- Exploring how to prepare zero-downtime deployments
- Presenting Continuous Delivery best practices
