comment Optimising busy website with Varnish and lots of ram
By removing cookies on static content in vcl_recv - if you ever have a missing image/css/js file; the cookie will be stripped, the request redirected to the Magento bootstrap - and the subsequent customer session will be lost. This is A Bad Idea. Similarly, the max memory that Apache can use is the maximum PHP memory setting multiplied by number of children. Which if its a Magento store, is probably around 1GB ~= 200GB. The OP is probably massively over allocating on RAM. There isn't a use case for more than 2x CPU cores for Apache threads if its only handling dynamic content.

comment Use HAProxy or Nginx to Load Balance between VPS
And you cannot float a single IP between different providers without the use of either an MPLS network or BGP announcement. Either of which are far out of reach of the OP's capability and understanding. DNS is neither suitable for load balancing nor High Availability and your answer is just plain inaccurate.

comment Use HAProxy or Nginx to Load Balance between VPS
I'm not mistaking either. The OP was looking for a way to use multiple VPS's to load balance amongst multiple back ends. But was mentioning the use of a virtual IP, which means they were looking at UltraMonkey/Heartbeat or otherwise, in conjunction with HAProxy. The OP asked for load balancing plus failover - something you wouldn't get with a single load balancer, nor would you get with "DNS load balancing". You can't be highly available using a single load balancer, nor using DNS to load balance.

comment Use HAProxy or Nginx to Load Balance between VPS
It makes sense - you just don't understand. With MPLS or BGP - yes. With a bunch of VPS's from different providers - no. You would never be able to "float" a virtual IP between different providers. The best you could get is DNS to balance between those, then each of those balance between the backends - but then you're reliant on DNS - which isn't remotely appropriate for load balancing.
