Setting Up Nutanix Calm Software-as-a-Service

Calm (cloud application lifecycle manager) was and still is a function within the Prism Central management plane. However, as customers needs grow and there is a push towards consuming more SaaS (software-as-a-service) solutions Nutanix now allows us to run Calm as a SaaS product. This will provide continuous upgrades and availability to the Calm management plane to now decouple hybrid cloud application deployments, scaling, and management from the underlying HCI infrastructure. This also opens up the ability to fractionally consume Calm as a per month license based on consumption of managed machines within the applications.

For a quick overview of Calm see the video below.
