Abstract:
Cloud computing has evolved from a risky and confusing concept to a strategy that organizations large and small are beginning to adopt as part of their overall computing strategy. Cloud computing turns traditional siloed computing assets into shared pools of resources that are based on an underlying Internet foundation. Cloud computing makes these resources easier to use by providing standardization and automation. A private cloud provides a flexible environment with a higher level of security than would be available in a public cloud. Combining public services with private clouds and the data center as a hybrid is the new definition of corporate computing. To really comprehend the cloud, you need to understand the three foundational delivery models: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). In this paper, we examine the different models that are available to deliver cloud services â€“ both public and private.
