Helpful information about cloud computing, cyber security and more, all at a glance.
Whether a public, hybrid, virtual private or private cloud, everyone agrees that cloud computing key benefits include scalability, instant provisioning, virtualized resources and ability to expand the server base quickly.
The majority of public cloud deployments are generally used for quality assurance testing, or where user demand peaks and falls at certain times of the day, month or year. Generally, security and compliance requirements is not an issue. Private cloud computing, on the other hand, by definition is a single-tenant environment where the hardware, storage and network are bought by and dedicated to a single client or company. Hybrid cloud offers a mix of public and private cloud computing, where public cloud resources are integrated with private or virtual private cloud services to create a unique hybrid environment.
We’ve just launched our latest white paper on building and managing a cost-effective Hybrid Cloud! This white paper is ideal for executives and IT decision-makers seeking a primer as well as up-to-date information regarding the advantages of hybrid cloud and specific technology recommendations.
Read below for an excerpt about private, public and hybrid cloud:
The public cloud is defined as a multi-tenant environment, where you buy a “server slice” in a cloud computing environment that is shared with a number of other clients or tenants.
Most public cloud deployments are generally used for web servers or development systems where security and compliance requirements of larger organizations and their customers is less of an issue.
Private cloud hosting by definition is a single-tenant environment where the hardware, storage and network are dedicated to a single client or company. A more common type of private cloud computing solution is virtual private cloud hosting, a multi-tenant environment where companies achieve networking isolation while keeping costs down by buying hardware slices with other tenants and creating private subnets.
As opposed to public clouds, fully private clouds are not delivered through a utility model or pay-as-you-go basis because the hardware is dedicated. However, Virtual Private Clouds offer the same pay-as-you-go model as public clouds, with the added bonus of specifically provisioned hardware, network and storage configurations. Private clouds, including Virtual Private Clouds, are generally preferred by mid and large size enterprises because they meet the security and compliance requirements of these larger organizations and their customers.
