The success or failure of public cloud services can be measured by whether they deliver high levels of performance, security and reliability that are on par with, or better than, those available within enterprise-owned data centers.
Gartner predicts that the global public cloud computing market is set to reach US$131 billion in 2013, up from $111 billion last year. To serve this market with the performance, security and reliability needed, cloud providers are moving quickly to build a virtualized multi-data center service architecture, or a “data center without walls.”
