Private Cloud Computing
Enterprises looking to reap the benefits of cloud computing while minimizing the risks are increasingly settling on private cloud computing as the optimal solution. Many of these organizations have also concluded that the best way to implement a private cloud is by using VCE's Vblock™ Systems, the world's most advanced converged infrastructure. Vblock Systems combine EMC storage, Cisco server and networking components, and VMware virtualization technology into pre-integrated, pre-validated cloud infrastructure stacks that enable fast, simple, and dependable private cloud computing roll-outs.
What Is Private Cloud Computing?
A private cloud (also known as an enterprise cloud) is a cloud computing service deployed and operated for the exclusive use of a single organization. At first blush this notion seems at odds with the original ideal of cloud computing as embodied by cloud computing providers such as Amazon Web Services or Salesforce.com whose clouds are accessed through the internet by many different customers. If a private cloud is for the exclusive use of a single organization, what makes it a "cloud"?
Private cloud computing has several important things in common with public clouds, which together can be considered the core defining attributes of a cloud service:
- A high degree of virtualization of compute, storage, and networking resources, so that resources can be pooled and easily allocated across heterogeneous and shifting demands. With Vblock Systems, industry-leading VMware technology provides the pre-integrated virtualization layer.
- Support for multi-tenancy, whereby different tenants' applications and data are securely segregated and each tenant's service usage can be tracked and charged for. In a private cloud computing context, the multiple tenants are different groups within the organization, such as departments, project groups, or branch offices. Vblock Systems support secure multi-tenancy.
- Support for self-service by cloud users, through a portal and/or a set of web services APIs.
What Are the Benefits of Private Cloud Computing?
The benefits of private cloud computing are best seen in comparison to public clouds on one hand, and conventional IT architectures on the other. Compared to public clouds, private cloud computing provides enterprises a greater degree of control over and visibility into their systems and data. Many enterprises also believe private clouds to afford a greater degree of cloud computing security for mission-critical workloads.
Compared to traditional IT infrastructures, private cloud computing provides two overriding benefits:
- Marked improvement in IT efficiency.
- Enhanced IT agility in support of ever-changing business needs.
