Hey Venkyyes, sure...wanted to investigate the way Plivo cloud is being architected. The design/configuration decisions being made, along with the choice of cloud/IaaS provider and what are some of the parameters, tuning and tweaking that might be needed for it to work better in clouds like EC2, Rackspace etc., considering by definition, these public cloud providers rely on over-subscription of physical resources by implementing multi-tenancy models.
