Microservices

In most cases, the monolith you create is not going to be able to achieve web scale. As you break off pieces to refactor, you'll develop smaller services. This allows for the decoupling of components upgrade schedules, which speeds up product development. By adopting the continuous delivery pattern espoused by Jez Humble, you can deploy new features and measure their success quickly. We'll take a peek at these architectures in Chapter 5, Continuous Deployment - Introducing New Features with Minimal Risk. Isolation of your microservices will be the subject of Chapter 4, Security - Ensuring the Integrity of Your Systems. 

By providing easy to use, low cost SaaS options, AWS lets you focus on building software. High value feature development replaces low level toil. In Chapter 6, Ephemeral Environments - Sandboxes for Experiments, we'll present patterns that help foster collaboration between developers and operators. AWS composable services empower all team members to participate in the product development they know best.
