Stop fearing Friday and late-night deployments!
Discover how the most painful part of software development—deploying to production—can become routine, safe, and even boring.

In this episode, I sit down with Valentina Servile (ThoughtWorks lead developer and author of “Continuous Deployment”) to discuss the principles, practices, and mindset shift required to achieve true Continuous Deployment.

Key topics discussed:

The key differences between Continuous Integration, Continuous Delivery, and Continuous Deployment
Why “if it hurts, do it more often” is the secret to safer, faster releases
Applying Lean principles like one-piece flow and reducing batch size for higher quality and speed
The importance of removing the final manual deployment gate and automating everything
Essential minimum practices: robust automated testing, feature flags, static analysis, and zero-downtime deployments
Separating deployment from release with feature flags and expand/contract patterns
Overcoming challenges in regulated industries, technical hurdles, and third-party integrations
The critical mindset shift: treating production as a first-class citizen and embracing “shift left” for quality and security
Cautions and advice on using AI tools in a continuous deployment workflow

Tune in to level up your software delivery and learn how to make deployments so routine that you’ll never dread another release.
