FORGET IT INFRASTRUCTURE COST-MOVE TO CLOUD COMPUTING:

KNOWING ABOUT CLOUD COMPUTING:

Cloud computing is a term which we are hearing every now and then, whenever we discuss about data, database, storage of data we always hear a term associated with them is cloud computing because now a days companies are focusing to work on their core competencies and core business rather than expanding resource on computer infrastructure and its maintenance. What is cloud computing? How it works? What are benefits of cloud computing? How it advantage companies? To answer all these question here is a small blog which will make you understand about cloud computing.

Cloud computing is the pool of configurable computer system resources, which provides high level of service and rapid provision of service with minimal efforts required by management as it allows companies to consume computer resource such as storage applications, virtual machines (VM) rather than maintain this service in-house with infrastructure. The definition suggests that cloud sourcing enables companies to maintain a cloud of data to third-party and do focus on their core business rather than taking tension about managing space for data. This cloud computing can minimize the cost of in-house infrastructure.

Key characteristics of cloud computing is:

1.       Organizations can move easily and with a speed as cloud computing provides them flexibility and expanding technological infrastructure resource.

2.       Cost reduction for companies as when companies subscribe public-cloud model so they covert their capital expenditure to the operational expenditure.

3.       The maintenance of cloud computing is much easier as they should not be installed in every computers or something like that and can be access by different places, different working conditions.

4.       Multitenacy enables sharing of resources and cost across the pool of users.

5.       The performance I monitored by the IT experts from the service provider.

Deployment models:

1.       Private cloud: the private clouds are solely operated by single organization, it is capital intensive method which is managed internally or externally. These private clouds have criticism on them that they still have to be buy build and managed. But it has its benefits also.

2.       Public clouds: a cloud is called public cloud when the service is rendered over a network that is open for public, there is no difference between the architecture of public and private clouds, and however security consideration may differ in the service of storage application and other resources.

3.       Hybrid cloud: hybrid cloud is the composition of both clouds public and private, they remain distinct entities but bound together offering its benefits. Basically it allows one to extend the capabilities and capacities of cloud servicing by merging and expanding services to the other cloud type.

Security and privacy:

There are security and privacy concerns about cloud computing because the service provider can access data any time. It could accidentally and deliberately delete or alter the information which can be negative for company and service provider can share information with the third party. These are some of the security and privacy issues regarding cloud.

Disadvantages:

Companies have limited customization options, cloud computing is cheaper because of its economies of scales and you get what you get, they don’t work on your demands. Companies do cloud computing and take a risk and should match against benefits. Secondly privacy and confidentiality is a big concern that company is providing there all data to a cloud, so there is a concern of privacy and secrecy which can leads to serious issues.

In conclusion of this blog I will recommend that companies who cannot bear IT infrastructure cost they should go for cloud computing as it is beneficial in terms of economies of scale.
