VAC versions and Varnish

VAC version Varnish version Varnish agent
3.9.3 latest 6.x latest 6.0 latest
3.8.3 6.x 6.0
3.8.3 or lower 4.1.x 4.1.x
3.8.3 or lower 4.0.x 4.0.x
3.8.3 or lower 3.x 3.x.x.

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.
