Question about the licencing of CF9 Eterprise vs Standard.

Hello,

Many thanks for your answers, it helps clarifying a lot !

As Adam I've never run a true "cluster", we always have loadbalancers to do the hard work. Store the client data in a centralised database and Bob's your uncle, loadbalanced CF without needing any kind of true clustering.

We used to run standalone machines but due to the virtualisation licensing mentioned we now run one physical machine with VMWare ESXi, then install as many Windows VMs on as we need. Once CF Enterprise licence covers you for all of that and any more you wish to deploy on that physical header.

Because CF's bottleneck tends to be its heap size and memory management, you'll get infinitely better results from using four VMs each running a 512MB-1GB heap rather than one beast of a machine with a 2-4GB heap.

Once you've deployed your fifth machine the Enterprise licence has paid for itself anyway, plus you've got all the extra security and monitoring features which come with it.

Do it, you know you want to.

Well an Enterprise licence will allow one to run as many CF instances (on one machine) as one likes: it's licensed by CPU not by instance.  A standard licence only allows for a single install.

That would be a major consideration for me, if I was looking at what you're doing.

I have no experience using the CF clustering, so cannae answer you on that one.
