@eljuanchosf@eljuanchosf

BOSH

“... unifies release engineering, deployment, and lifecycle management of small and large-scale cloud software.”

Provision and deploy software

Monitoring

Failure recovery

Software updates with zero-to-minimal downtime

@eljuanchosf@eljuanchosf

BOSH

Complies with the four principles of Release Engineering:

Identifiability

Reproducibility

Consistency

Agility

Well suited for large, distributed systems

Support many IaaS providers

Very active, friendly and responsive community

Born to deploy Cloud Foundry, now used to deploy all kinds of software

@eljuanchosf@eljuanchosf

When use BOSH?

When you want to avoid coupling with IaaS.

When you are working with a distributed system.

When you want lifecycle management.

When you want to manage and test deployments upgrades/rollbacks on different environments.
