But nowadays, if the service needs more computing resources, we just has to deliver new server for it automatically. Service 1 Several solutions exist for deploying machines/servers such as Puppet , Chef automatically. However, even if the deployment of a machine becomes simpler, the deployment of the business product composed of services stay complex. Problematic: Why its complex: Service 2 Service 3 Business Product

So, it has a high level of abstraction. Goal: Service 2 Service 3 Business Product For managing services, Juju is based on events and so it can do orchestration unlike machine deployment solutions such as Puppet or Chef. How:

Consequently, juju answer several cloud concept such as: - elasticity / dynamicity, resiliency … However, juju does not share resource, that’s why a such solution could be coupled with other tools to be more efficient (e.g: docker). In our example, we use juju with Amazon, but it could works with other clouds or its own cloud composed of virtual or physical machines. At last, this easy use of cloud is well adapt for automation and deliver easily new components in production and so allow us to work more efficiently with agile methods also.
