Episode notes
Network Automation Goals
- Network automation aims to improve scale, complexity, frequency, and accuracy of changes.
- Focus on these goals, rather than simply adopting tools like CI/CD pipelines for their own sake.
Midnight Deployments
- Tony Bourke's previous sysadmin experience involved deploying code at midnight.
- This often resulted in system failures, highlighting the need for better deployment practices.
CI/CD Inseparability
- Continuous Integration (CI) and Continuous Deployment (CD) are tightly coupled concepts.
- They are difficult to separate and often used interchangeably, even being combined into 'CI' by some.
