Private Cloud for the Public Sector
by David Baum
Cloud computing is a model for enabling convenient, on-demand access to a shared pool of configurable computing resources. It is easy to make adjustments to the overall computing capacity, thanks to the cloud’s shared and elastically scalable architecture. There are two basic cloud models: public and private.
While a public cloud includes applications, storage, and other resources that are available to the general public, a private cloud provides those same capabilities but is operated solely for a single organization, such as Local Government Information Systems (LOGIS) and its members. It can be managed internally or by a third party, and can be accessed via the internet or a virtual private network.
According to Mike Garris, executive director at LOGIS, private cloud technology has become progressively more viable as wide-area networks get faster, bandwidth becomes more plentiful, and elastic scaling technologies support business growth. Cloud users simply need a client device such as a laptop, desktop, tablet, or smartphone to access a cloud system via the Web. The cloud provides server-based functionality and data services to the user, with output displayed on each client device.
Oracle enables many types of cloud models using proven technologies that have been evolving for years, including clustering, virtualization, service-oriented architecture, and management automation. These technologies allow LOGIS to scale its cloud incrementally and adjust resources to meet dynamic business priorities, bolstered by advanced methods for cloud maintenance, access, and authentication.
“Utilizing a private cloud is a good middle ground between placing assets in a public cloud, where you don’t have much security or control, versus doing everything on your own,” Garris says. “Our shift to a cloud model, SaaS [software as a service], and managed services are the newest services available to our members.”
