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.
