1.Break engineering into smaller teams.2.Engineer a software architecture to

support this organization.

The traditional n-tier architecture makes it hard for smaller teams to iterate.

We need a cloud architecture that

supports continuous uptime distributed

development.

Each component must be hot swappable.

Architecture must be resilient to network, machine, and people failures.

Summary

● Microservices is an architecture for distributed development of cloud applications.

● A resilient architecture is one of the three key components required to successfully adopt microservices (the other two are CD workflow and loose coupling)
