A hybrid cloud is a combination of public and private clouds allowing IT organizations to become a broker of services—some they provide on their own and some they procure from public cloud sources.
Who uses hybrid clouds and why?
Enterprise IT organizations and government entities are leveraging hybrid cloud to enable greater simplicity, choice, agility, lower costs, improved SLAs, visibility, and control.
Cloud computing enables access to a variety of IT resources in minutes to hours and aligns costs to actual consumption. A hybrid cloud is the most flexible and cost-effective cloud computing model, combining what the internal IT department does best with the capabilities of external IT providers.
By enabling the organization to initiate projects faster, capitalize quickly on new capabilities and revenue opportunities, and respond nimbly to market changes, moving to a cloud infrastructure elevates IT from cost center to strategic partner.
How does the hybrid cloud work?
The foundation of a hybrid cloud is a virtualized infrastructure upon which a self-service portal is layered that uses automation to accelerate delivery of applications and services. Those applications and services can originate from private and public clouds, but are all presented through a single self-service portal. The self-service portal also delivers financial transparency and operational management to ensure the entire environment can be managed to specific service levels defined by IT, while the business knows what it’s paying for and how much.
Private clouds provide fast, on-demand access to off premise, enterprise-class services and resources at a competitive price. By connecting private and public cloud resources, IT can manage both traditional and next-gen applications together in a way that is consistent and seamless to the end user.
Among the many types of cloud computing services, the most common are:
• Software as a Service (SaaS)
• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
What are the benefits of a hybrid cloud?
• Greater agility – IT resources can be provisioned on demand and returned to the resource pool easily
• Rapid scalability – instantly allocate additional computing resources to meet business demands due to peak seasons, company growth, or decline
• Lower costs - infrastructure, energy, and facility costs become a “pay as you use” model
• Greater IT staff productivity – automated provisioning through self-service portal
• Reduce wasted resources – transparent pricing and metering and chargeback tools allow IT admins to pinpoint where costs can be reduced
• Higher utilization of IT investments
• Enhanced security and protection of information assets
• Ability to broker services from public cloud sources rather than having to build them as a private cloud model would require
• Regain visibility into IT purchases made by lines-of-business operating outside the visibility of Enterprise IT
