Overview of this book

This practical guide to DevOps uses GitHub as the DevOps platform and shows how you can leverage the power of GitHub for collaboration, lean management, and secure and fast software delivery. The chapters provide simple solutions to common problems, thereby helping teams that are already on their DevOps journey to further advance into DevOps and speed up their software delivery performance. From finding the right metrics to measure your success to learning from other teams’ success stories without merely copying what they’ve done, this book has it all in one place. As you advance, you’ll find out how you can leverage the power of GitHub to accelerate your value delivery – by making work visible with GitHub Projects, measuring the right metrics with GitHub Insights, using solid and proven engineering practices with GitHub Actions and Advanced Security, and moving to event-based and loosely coupled software architecture. By the end of this GitHub book, you'll have understood what factors influence software delivery performance and how you can measure your capabilities, thus realizing where you stand in your journey and how you can move forward.

Inverse Conway Maneuver

Now that we know the optimal size for our teams, we can perform something that is called the Inverse Conway Maneuver (Forsgren N., Humble, J., and Kim, G., 2018, page 102). If you evolve your organization structure to autonomous two-pizza teams, your architecture evolves into a more loosely coupled one.

But it's not just the team size! If you create your teams around functionalities, it will result in a layered or multi-tier architecture. If you put frontend developers and database specialists in teams, your architecture will decouple at these communication points (see Figure 17.5):

Figure 17.5 – Functional teams lead to a layered architecture

To achieve a deployable and testable architecture that empowers the teams, you must create cross-functional teams responsible for business outcomes. This will lead to the desired architecture that helps you to move fast (see Figure 17.6):
