11. 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.

14. 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
