“Cloud is about how you do computing, not where you do computing.”
~ Paul Maritz, CEO of VMware
With the ever growing demand of the data and production, constant innovations, the demand for data and storage increased exponentially. This resulted into the greater demand for the expensive hardware. The tables were consumed in the cluster of metal and silicon. Companies used to spend fortune in order to get the apt hardware and well as the place to store such enormous metal bodies, carrying all sorts of information. The data stored in such arrangements often used to crash, which caused irreversible damage to data. Also, it was really difficult to make the changes or update the data and software with the development. Also, the data was fixed at a location and wasn’t available as per our requirement, i.e. it lacked portability.
With the deployment of “cloud” in the mainstream, many factors such as security, productivity, cost efficiency, speed enhanced with leaps and bound in the field of computers and networking.
Cloud computing is basically a delivery apparatus for computing services which include – storage, database,software,analytics and also intelligence. The main objective behind this is to offer faster, flexible and economically friendly development and innovations for your business. It reduces the overall operational cost ,executes the framework and adapt as and when the business demands an update. The reason why it is called the “cloud” because it employs THE INTERNET in order to carry out its functionalities.
TYPES OF CLOUD COMPUTING
We need to decide what is the purpose of the cloud, consider the usage and purpose and then decide which cloud we want because not all clouds are same and not every cloud is for everyone.
1.PUBLIC CLOUD: In public cloud, all the services, setup and the skeleton is provided by the service provider and all these are owned by them only. All the hardware, software and the services are under the management of the owner (cloud service provider) and the user, access these services using the web browser. Eg: MICROSOFT AZURE
2.PRIVATE CLOUD: Unlike public cloud, private cloud is owner, controlled and managed by an organisation or business, exclusively. A private cloud can be physically located on the company’s on-site data center.Entire infrastructure of the cloud and its services is maintained on a private network. Eg: MEGHADOOT (SBI)
3.HYBRID CLOUD: Hybrid cloud merges both, public as well as private cloud and its respective services. Both are ties together by the technology they are utilizing and they are able to share application and data between them. Hybrid cloud is more preferred over the other cloud services because they provide us with more flexibility and more options to develop the existing skeleton. Its an enhancement in the security measures as well as submission. Eg: AMAZON WEB SERVICES (AWS)
PURPOSE CLOUD COMPUTING
1.DELIVER SOFTWARE ON DEMAND
2.STREAM AUDIO AND VIDEO
3.ANALYSIS OF THE DATA
4.TEST AND BUILD APPLICATIONS
6.STORAGE, BACKUP AND RECOVERY
7.CREATE CLOUD NATIVE APPLICATIONS
