• Clear physical boundaries between projects and services.
• One-to-one mapping of source control repositories and services or projects.
• It is easy to map deployments of services to source control repositories.
• Uniform treatment of all dependencies—internal and third party.

However, there are significant costs to this approach, especially as the number of services and projects grows and the dependency graphs between them become more complicated:

• Applying changes often requires changes across ...
