CIOs, CXO, and CTOs are all chirping the word ‘Cloud Computing. Marking a reality to the Internet and its new game-changing possibilities, Cloud in recent times has been all over. Today, Cloud computing is the standard way for technology companies to access IT infrastructure, software and hardware resources. With IT operations and infrastructures spread its wings to almost every sector the need for adaptable and scalable software and hardware has also witnessed a demand. And Cloud Computing seems to have all the answers with it. What is so hysteric about this technology that in a short span of time it has taken over every business? Hence, in this article, we will explain to you types of Cloud Computing and how it became a multibillion-dollar industry.
Private Cloud has a marginal difference to Public Cloud. Private Cloud as the name suggests uses dedicated private hardware. A single organisation using or operating a complete cloud infrastructure or often said ‘Network’ is mainly stated as a private cloud. It is not shared with others, yet it is remotely located. Businesses use options on-premise cloud in private cloud which is said to be a major drawback as the complete infrastructure i.e. management, maintenance, and data center is complete responsibility of the company. Over time, it’s expected that your servers will need to be replaced, which can get very expensive and hit budgets of companies massively. On the other hand, private clouds offer an increased level of security and they share very few, if any, resources with other organizations.
Why public cloud took over all other cloud computing offerings is their lucrative sense of ‘pay as you go’ billing model. Public cloud refers to a computing service model used for the provisioning of storage and computational services to the general public over the internet. In this service, a service provider manages a public cloud solution’s core infrastructure, software and other back-end architecture in a multitenant environment allowing business to focus in their respective work. This term is almost redundant as, by definition, something on the cloud is generally available. There is however a differentiation between the public cloud and private cloud. The delivery model of a private cloud is pretty much the same – it is still cloud computing. However, the services in a private cloud are provided behind a firewall and are only accessible to the users or partners of a single organization. Gartner predicts the worldwide public cloud service market will grow from $182.4B in 2018 to $331.2B in 2022, attaining a compound annual growth rate (CAGR) of 12.6%.
Hybrid Cloud is a team-up of private and public cloud. It delivers the private cloud’s high-security features coupled with the fast connection and easy-to-access features of the public cloud. The hybrid cloud’s popularity rose due to its benefits to enterprises. Hybrid Cloud capitalizes on a similar low-cost approach as the public cloud. Alike private cloud, hybrid clouds behind a firewall offers scalability to handle fluctuating computing demands. In other words, the hybrid cloud may scale up to use the public cloud or down to the private cloud.
The other above three services have been for a long time, Community Cloud is been evolving to derive more tailored services for businesses. Wherein, the cloud has always been blamed of security hindrances. Community cloud, in other hand, says to simplify the term as community cloud refers to a shared cloud computing service environment. It simply means communities in it share similar security, privacy, performance and compliance requirements. Companies with regulatory compliance and strict business provinces are attracted to this model. Sectors like health, financial or legal. They are also apt to managing joint projects that benefit from sharing community-specific software applications or development platforms.
