Openstack and the service delivery challenge

Openstack offers an infrastructure to deploy and scale virtual servers instantly...

...but complexity in configuring, integrating and scaling services makes deployments harder.

.

Openstack typically requires deep knowledge of components that comprise it such as glance,

rabbit-mq, cinder, etc. and configuring the inter-relationships between them. In addition, you have to

deal with the workloads/applications you will deliver and their inter-relationships which further

increases complexity and time in deployment.

The solution:

The next generation service orchestration framework

Juju and Charms

●Juju utilizes service formulas called Charms”

● Charms are building blocks

●Charms contain instructions :

Deploy, Install, and Configure

●Charms can be instantiated one or many times

Juju environment

●Juju maintains the relations between the services

●Eliminates complex configuration management
