Overview of this book

The world of software delivery and deployment has come a long way in the last few decades. From waterfall methods to Agile practices, every company that develops its own software has to overcome various challenges in delivery and deployment to meet customer and market demands. This book will guide you through common industry practices for software delivery and deployment. Throughout the book, you'll follow the journey of a DevOps team that matures their software release process from quarterly deployments to continuous delivery using GitOps. With the help of hands-on tutorials, projects, and self-assessment questions, you'll build your knowledge of GitOps basics, different types of GitOps practices, and how to decide which GitOps practice is the best for your company. As you progress, you'll cover everything from building declarative language files to the pitfalls in performing continuous deployment with GitOps. By the end of this book, you'll be well-versed with the fundamentals of delivery and deployment, the different schools of GitOps, and how to best leverage GitOps in your teams.

Continuous deployment considerations

The DevOps team began breaking down the different parts of their deployment process. They also started gathering complaints and concerns from developers, and figuring out what industry practices should be implemented to achieve continuous deployment.

One of the major concerns that they had heard from the different teams was that every deployment was a black box for them. From the moment the deployment was triggered, the team had no understanding or insight into how it was behaving. A failed deployment could take hours to find and fix. Although the resolution to this would be increasing the log output, the core issue is the lack of transparency. The ability to achieve a continuous deployment practice relies heavily on transparency into what is happening and shortening the overall feedback loop to the teams. The DevOps team would need to implement transparency and feedback as a best practice for deployments.
