Development Staging Production

● Local machine, single user

● Runs tip of everything

● One instance of each service

● Controlled environment

● Sometimes auto-rollout from tip

● A few machines

● A few instances of each service

● Stable, tested code

● Minimal downtime

● Many more machines

● Many more services

● Must be easily scalable

Dev Ops

DevOps

● Reuse existing deployment charms in an openly-accessible repository of shared

expertise

● Reproduce deployments for test and staging purposes

● Rapid deployment of your dependencies for development purposes

● Compose whole systems from individual application components and describe the entire deployment

● Explicit control over deployment,

configuration and upgrade options

● See what’s deployed and track usage in the

cloud

● Create and share charms for new applications

● Monitor, scale, shrink and adjust deployment

parameters in real time

● Explicitly connect different components and maintain those relationships over time

● Collaborate with developers on the exact deployment and upgrade processes

● Get more done: implement decisions immediately regardless of infrastructure scale

adding more units

● juju add-unit <service>
