Infrastructure First Development

Cloud Native is code for “Rewrite the world”

What if you could defer infrastructure

decisions until runtime?

HabitatApplication automation that enables modern

application teams to build, deploy, and run any application in any environment - from traditional

data-centers to containerized microservices.

Build Service

Plan Artifact DepotBuild

Service

A Build Service with a workflow to describe the software and behavior for Habitat applications

Explicit about dependenciesIncludes what is configurable about the application

Packages are developed and built in an isolated build environment (hab studio)

Built Artifacts are post-processed in one step to multiple formats including Docker Images

Source Code Repo

Applications run as distributed, fully automated, and capable autonomous actors

Immutable applications, but flexible and easy to manage because automation travels with the application

Bundles what your apps need to run and nothing else (new and legacy)

Embedded automation choreographs application cluster topology/behavior

A network with no reliance on external services and no single-point-of-failure

Provides continuous deployment without traditional Application Release Automation (ARA) tooling
