Ronald Schmelzer is a Managing Partner at ZapThink LLC. His article addresses the debate about private clouds. There are many companies that are afraid of deploying critical applications and/or data in a public cloud environment. Instead, many are contemplating building their own internal cloud which goes against much of the value proposition of cloud computing and keeps their dependency on expensive commercial software. Ron argues that the concept of private clouds is a marketing term used by vendors rebranding their products.
Tom Lounibos, CEO for SOASTA, discusses how the pay-as-you-go cloud computing model allows SOASTA to simulate performance tests with loads that were simply not feasible in the on-premise world.
