Cloudify 4.5 Release Notes

What’s New

Agents Improvements – new commands for listing agents are now available, simplifying tracking agents and their status including filtering options during installation.
Snapshots Improvements – snapshots are used to backup Cloudify’s state for upgrade and DR purposes. The process, including restoration from snapshot, has been improved and is now more robust, performant, and includes more options (such as queuing and skipping some failures)
Microservices Architecture – as part of Cloudify’s progression towards a micro services architecture an external DB is enabled. This setup is currently only supported for a single manager, and will be enhanced to support a cluster in the next release.
Actionable Events – pluggable framework enabling taking actions upon Cloudify events, with an OOTB implementation of SNMP traps for workflow related events
Deployment Wizard – UI guidance for blueprint deployment, enabling users to get to a running deployment quickly and efficiently
Multi management network post-bootstrap configuration – Added ability to add new environments on the fly via manager networks configuration.
K8S integration – enhanced support for bare metal and a variety of network implementations
Openstack networking enhancements
Azure support improvements
