Team organization

When teams of engineers are working on separate code bases with separate deployments, they are able to make a lot of decisions independently, without the need to coordinate with other teams in the organization. This means that engineers are free to commit code, design their own code review processes, and deploy to production without always needing to coordinate. In a monolith, it's not uncommon for engineers to have to get their changes into a queue that is then deployed at a set time with changes from other teams. If something goes wrong (poison deploys are one of the most common causes of outages), then the whole change set gets rolled back, delaying work by multiple teams. Microservices help you avoid this by allowing teams to move with more autonomy.
