Cloud Connector
Zerto Cloud Connectors are custom, very thin, Linux-based virtual machines with a small footprint and disk – memory and CPU – that have been hardened to limit the number of running services to the bare minimum. By default they run only the Zerto protocols and SSH. All other protocols and services, such as the Cron services and ICMP redirects, are either not installed or are turned off.
Zerto uses different types of network services and was designed to work in conjunction with existing network security elements.
• | Firewall |
Zerto components can be deployed behind standard firewalls.
Note: | Zerto does not support NAT (Network Address Translation) firewalls. |
• | SSH |
The Zerto components do not require SSH for remote access and access can be closed via the firewall software, only allowing SSH access from authorized clients.
The Zerto Virtual Manager communicates, as a client, with ESX/ESXi hosts securely either via HTTPS, running Zerto with VMware vSphere 4.x or SSH when running Zerto with VMware vSphere 5.x.
