Cloud computing may be a confusing subject because of the number of different businesses offering what they call “cloud computing,” but it's not as complicated as it sounds. There are three types of cloud computing infrastructures, each with its own benefits. Three types of Cloud Computing Public Clouds: Always accessible, but low in security The mainstream version of cloud computing is the public cloud. The public cloud has been popularized by various consumer-oriented service providers. • Public cloud is delivered through a third- party service provider. • Public cloud services are billed on a per use model. • Services are offered on a self-service subscription basis and are dynamically provisioned for customers. • Customers manage their own services. • Everything runs over the public Internet, which means good accessibility but lower security. • More ideal for consumers rather than businesses. • Have a fairly standardized set of specs with limited capability to customize infrastructure. • Save on opex and have zero capex. Private Clouds (or virtual private clouds): Greater control and security Private cloud environments take the benefits of public cloud computing technologies and place them on a private network, whether it's hosted internally on a company's physical infrastructure or by a third-party service provider. • Private IPs and firewalls offer greater corporate data security and privacy. • Virtual and external private clouds are delivered through third-party service providers, usually on a common platform. • Value-added services like managed backups and greater flexibility and security make private cloud services better suited to business applications than the public cloud. • Data security is a priority, so it offers more peace of mind. • Greater control over the environment is available. Hybrid Clouds: Best of both worlds Most business cloud deployments today are being done in hybrid environments, which integrate private clouds with other infrastructures, whether they are public clouds or physical systems. • More complexity means additional benefits around enhanced security and integration. • Businesses can opt to put more sensitive data on physical servers for increased security but still get the benefits of cloud computing. • Keep costs down by utilizing existing physical infrastructure that are integrated with a private cloud. • Application portability means shifting apps from the cloud to servers and back again as needed. The most common cloud computing services can be described as Infrastructure as a Service (IaaS), which is a utility computing model that provides customers with on-demand virtual servers and storage. Applications in the cloud are generally available through a standard web browser, and cloud computing is priced on a usage-based subscription service.
