The recent explosion of DevOps tools and techniques means that releasing new features doesn’t need to be a stressful all-weekend slumber party. Rouan will give you a set of steps you can take to move your release process from zero to hero. He’ll show you how to gain confidence in your changes with automated testing and a build pipeline. He’ll share his experience of implementing push-button deployments to production, so that you can shrink your margin of error right down. He’ll tell you about Infrastructure as Code and how you can have your very own phoenix servers, so that disaster recovery is built into your release process. Finally, he’ll share techniques for blue-green deployment so that you can deploy with no impact to your customers.
