Cross-Site Large-Scale Software Delivery with Enhanced Git Branch Model

As the organization grows onto multiple countries, several feature deliveries become more complex and introduce interactive impact. Since the widely used Git branch model could not well support cross-site concurrent development, this paper points out the challenges of large-scale software delivery for engineering teams across sites and propose an enhanced Git branch model, including geographic branch hierarchy and weekly release cycle to reduce Git merge complexity and ease feature planning. The theoretical model and practical historical data are provided to prove the effect.
