Enabling a truly dynamic data center, cloud infrastructure is typically composed of the following hardware and software elements—all of which are integrated and optimized to achieve agility, scalability and superior manageability:
- Compute, storage and network equipment. Servers, storage devices, and network components (switches, routers, etc.) provide the physical foundation for a cloud infrastructure.
- Virtualization software. Through hypervisor technology, cloud computing virtualization is used to deploy, pool and allocate virtual machines on top of the physical resource layer, dramatically improving physical resource utilization and bringing new levels of agility and scalability to the data center.
- Cloud management software. A cloud management solution allows for the automation of workflows that align and configure virtual components, enabling on-demand, self-service provisioning of resources and simpler, more efficient management of the IT infrastructure.
Models of Cloud Infrastructure Deployment
The most common deployment models of cloud infrastructure are the public cloud, the private cloud, and the hybrid cloud, which is a mixture of public and private clouds. Public clouds are cloud infrastructures created and run by third parties to deliver infrastructures, platforms and applications "as-a-service" to multiple clients. Resources from a public cloud can be used to augment the IT capabilities of an organization as necessary, thereby shifting the burden of infrastructure purchasing and maintenance from the enterprise to cloud computing providers. Although easy to use and unlimited in scalability, the public cloud is not a suitable deployment model for all organizations and workloads.
Enterprises requiring greater visibility into and control over the cloud infrastructure and the utmost level of cloud computing security will be more comfortable with a private cloud, also known as an enterprise cloud. With this deployment model, the cloud infrastructure is designed and built exclusively for the use of a single client or enterprise. Because the client typically owns and maintains control over the cloud environment as well as the delivery and security of services, internal IT departments face significant challenges in the implementation and management of a private cloud infrastructure.
