A general comparison between private be seen in the following table. Private Cloud Defined A compiled definition of private cloud or internal cloud based on is an environment which is capable of running and implementing characteristics of cloud computing like virtualization and layered services over the network but at the same time also applies stricter policies and requirements like security, latencies, SLAs and also usage of existing datacenter resources. The rest of this article will briefly summarize private cloud, a type of cloud environment which is designed to be run with stringent requirements that may fit the enterprise-level SLAs. The notion of offloading data and process to third party infrastructure or software providers in cloud computing may not be a sound idea in the enterprise realm. Concerns raised over the cloud computing are mainly related on how secure and reliable the cloud is to support enterprise-level requirements. However, decision over implementation of certain technology in companies should have passed due feasibility study. Some success stories of technology shift from legacy system to the cloud may have tempted institutions or companies to leverage cloud computing paradigm in their organization. An existing cloud user may have been familiar with Amazon EC2, Amazon S3, Google App Engine, Apache Hadoop, Cloudera and other products from companies providing cloud infrastructure or cloud-based software and service. An Introduction to Private Cloud As the word “cloud computing” becomes more ubiquitous these days, several questions can be raised ranging from basic question like the definitions of a cloud and cloud computing to more tempting questions like architecture of cloud infrastructure and implementation of cloud computing to solve complex, data-intensive compute problems.
