Lesson 1 — Minimizing downtime and risk with advanced deployment strategies
Prerequisites and goals
Prerequisites
Theoretical prerequisites
This lesson assumes that you already know the following:
- The difference between and benefits of differentiated testing, staging, and production/live environments
- Understand how and why to separate environments, including the isolation of changes and the progressive steps toward live deployment
- Understand the challenges associated with database versioning and migration
- How to perform database schema and data migrations in TYPO3 as part of a CD workflow
- Know the theoretical best practices for handling these changes seamlessly
Practical prerequisites
Before you start this lesson, please have the following things ready:
- Configured TYPO3 differently for development, testing, staging, and production environments
- Implemented scripts or tools that manage database changes
- Ensure that migrations are smoothly and automatically handled during deployments
- Demonstrated the setup of each environment and validated that each configuration and migration strategy works as expected
Goals
Theoretical goals
By the end of this lesson, you should know the following:
