It is a widely acknowledged fact that systematic storing, managing and retrieving of data is quite crucial for any organization to operate smoothly, without a glitch. Hence, enter cloud computing- the all new way of backing up data. The system of cloud computing involves storage of data using a web based remote server. This is advantageous, provided one chooses the apt model for the purpose.
Cloud Deployment Models
How does cloud computing work with respect to securing and preserving data? Let us take a closer look at the various cloud deployment models to understand the whole process. Needless to say, each of these deployment models caters to the requirements of a specific group of people:
Public Cloud Deployment Model
The cloud computing resources made available to the general public over the internet by cloud service organization is termed as Public cloud deployment. This cloud deployment model allows clients to provide services to themselves by means of a web server without capital investment in a data center. The expenses are instead shared among customers availing the services.
Private Cloud Deployment Model
The private cloud deployment model, on the other hand, is meant for a specific group with the infrastructure and utilization being restricted to a certain organization. Since this cloud deployment model is subject to the physical, procedural and electronic security of the organization, there cannot be any question about the high security coverage of the model. The improved performance of the physical hardware in this system means enhanced efficiency both in terms of expenses and performance.
Hybrid Cloud Deployment Model
As evident by the term, hybrid cloud computing refers to the blend of both the private and public cloud deployment models- the security of the private cloud and the cost efficiency of the public cloud.
What Is Public Cloud Deployment?
Also known as the multi-tenant cloud, the public cloud deployment model can be said to be the definition for the mainstream cloud computing model. In this model, multiple clients make use of a single cloud wherein the expenses of operational IT get reduced. The resources are typically deployed by means of the web-based server from a third party service provider. The service is hosted by a cloud vendor and is made available for use to the common public and large scale industries.
The public cloud deployment model is most compatible with business requirements which require spike loading, make use of temporary infrastructure meant for development and trial of applications, hosting SaaS applications and the like. Google can be said to be one such cloud deployment.
The Pros of Public Cloud Deployment
Let us examine the most desired aspects and characteristics of public cloud deployment model that makes it popularly opted for:
Reduced expenses are perhaps one of the greatest advantages of public cloud deployment model. With the model being made available to a vast section of clients, the cost of the model, too, gets divided and thus, reduced.
The resources, too, are available as and when required with fluctuating demands. Not to mention, the high scalability of the model makes it the ideal deal.
Perhaps the best part of the model is pay-as-you-go system. You pay only for what you have used.
