[Freeswitch-dev] High Availability Communication Project #1

[Nathan Neulinger]

In our case, we didn't have the "two machines" requirement, but had the same 'didn't want to deal with services on the 
same box issue). We're using:

Real Hardware:
	x-p1 / x-p2 (Keepalived for one floating IP for each of internal/external networks) - serves provisioning http(s), 
tftp, and FS itself

Virtual Machines on another cluster (not jitter/drift sensitive):
	x-db-p1, x-db-p2, x-db-p3 (Percona XTraDB Cluster + keepalived for single floating IP)
	x-gfs-p1, x-gfs-p3, x-gfs-p3 (Glustre Filesystem) - only using this for a loosely consistent persistent store for 
voicemail, logs, etc. Could easily be merged with other instances.
	x-web-p1, x-web-p2  (end user accessible web, frontended with existing on-prem load balancer and ssl offload)


The actual setup and resource requirements are quite low other than having a bunch of smaller VMs.
