VAC communicates with the Varnish Cache server(s) trough the Varnish Agent.
It is distributed as Debian/Ubuntu deb packages, Red Hat RPMs.
VAC has modest hardware requirements. A virtual machine with 1GB RAM and 10 GB disk space is sufficient for ordinary installations. As a rule of thumb estimate each instance to add around 300MB overhead
From version 3.0.3 and above the VAC requires Java Runtime Environment version 7 or above.
Note that VAC 3.0.0 and above will require varnish-agent 2.2.0 and above.
Earlier versions of the VAC, such as 2.0.x, is dependent on varnish-agent 1.16. Both are no longer supported.
