    Setting

    Requirements

    Volume

    • EBS volume that is not root.

    • Minimum size: Enough for 5-10 minutes of runtime (minimum 30 GB)

    Tags

    • Tag key: ZestyDisk

    • Tag value: True

    • Resource type: Volumes (not Instances)

    Network settings

    Outbound security group

    • Type = HTTPS

    • Destination = Anywhere-IPv4 (0.0.0.0/0 is the one that is needed, despite the AWS warning.)
      If you must provide a specific destination for outbound HTTPS traffic, the target URL is https://api.cloudvisor.io

    Required infrastructure

    • Your VPC must have outbound access to the internet. If this is not possible, Zesty Disk supports secured connectivity using AWS PrivateLink. For more information, see Enable PrivateLink for Zesty Disk.

    • Zesty Disk requires minimal CPU resources to operate. You are required to maintain at least 3% of free CPU usage to allow the Zesty Disk agent to operate. If your CPU usage exceeds 97%, the Zesty Disk Agent may not perform.
