So your ready to take your network off the ground and into the cloud — but which type of cloud deployment is the best approach for your organization’s IT needs? The first step is to ensure you have a solid understanding of the various cloud options available to you. Below are the most common types of cloud deployment models.
Most people associate cloud computing with the public cloud. A public cloud consists of a service provider offering resources, such as applications and infrastructure (server, operating system, network connectivity, storage, etc.) to an organization, a group of organizations and/or individuals, or the general public via the Internet. Well-known examples include Amazon EC2, Microsoft Windows Azure, Google App Engine and RackSpace. These services can also include, but not be limited to, business applications (i.e., ERP and CRM) accounting, data backup, and document management and enterprise content management (ECM) systems. Public cloud services may be free or offered on a pay-per-use model.
A private cloud (also sometimes referred to as an internal or corporate cloud) is cloud infrastructure operated for a single organization or a limited group or organizations, whether managed internally or by a third-party, and hosted internally or externally. A ‘private cloud’ typically appeals to an organization that requires a greater level of control over their data.
A hybrid cloud environment can combine private or public clouds as well as on-premise implementations that are connected together to deliver the benefits of multiple deployment models. The hybrid cloud model enables organizations to better utilize existing resources, provides a more customized degree of fault tolerance and security, and delivers local access without being entirely dependent on Internet connectivity. If an organization requires that certain business services and/or sensitive information must reside on-premise, but wants to leverage the benefits of hosted solutions to ease the burden on existing IT infrastructure, a hybrid cloud deployment offers an effective approach. In fact, GigaOM notes that 60% of businesses plan to implement a hybrid cloud model, combining cloud and on-premise deployments.
In addition to defining various cloud-based models, the new M-File white paper, Shaping Your IT Cloud, addresses the considerations and questions enterprises should take into account as they evaluate which cloud deployment model is ideal for supporting their specific IT requirements.
