A hybrid cloud is any modernized infrastructure that involves two or more delivery models: a private cloud, a managed private cloud and public cloud resources, including coordinated management/service provisioning.
Who uses hybrid clouds and why?
Organizations leverage hybrid cloud to enable greater simplicity, lower operating costs and increase the agility of their IT services.
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 consists of 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 the 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, and the business knows what its 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 Cloud resources with 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 or company growth
• 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
