Cloud Computing

Cloud computing traces its origins back to the 1960s, when the computer industry recognized the potential benefits of delivering computing as a service or a utility. But due to the lack of connectivity and the bandwidths in implementing the computing as a service It wasn't became practical. But withthe broad availability of internet bandwidth in the late 1990s the computing as a service bacame more practcal.

Cloud computing, Finally this can be generally define as delivery of hosted services over the internet.This is a computing paradigm, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. Applications such as e-mail,web conferencing,Customer relationship management(CRM) is run on cloud.

There are 03 types of clouds namely private, public and hybrid.Enterprises can choose to deploy applications from these 03.

These Cloud Integrators can play a vital part in determining the right cloud path for each organization. 

Private Cloud:

Private clouds are built exclusive for a single enterprise. Here the services are delivered from a business's data center to internal users.

Example:HP Data Centers

There are 02 variations to a private cloud.

01)On-premise Private Cloud: Also it is known as internal clouds and these are hosted within one‟s own data center. This model provides a more standardized process and protection, but is limited in aspects of size and scalability.For the applications which require complete control and configurability of the infrastructure and security this is best suited service.

02)Externally hosted Private Cloud: This type of private cloud is hosted externally with a cloud provider, where the provider facilitates an exclusive cloud environment with full guarantee of privacy. This is best suited for enterprises that don‟t prefer a public cloud due to sharing of physical resources

Public cloud: 

This is a third-party cloud service provider and delivers the cloud service over the internet.Example:Amazon

Hybrid Cloud:

This is a combination of public cloud services and an on-premises private cloud.This integrated cloud service utilize to perform distinct functions within the same organization. In an organization with hybrid cloud can maximize their efficiencies by employing public cloud services for all sensitive operations.

Example:ERP in private Cloud

Sales & Email on public

Cloud computing is a practical approach to experience direct cost benefits for both the business and the end user. And it has the potential to transform a data center from a capital-intensive set up to a variable priced environment.With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly.

Though these can be identified as the benefits of using this amazing technology.

-It reduce the complexity of the networks

-Do not have to buy software lisences.

-Cloud providers that have specialized in a particular area(such as e-mail) 

-can bring advanced services that a single company might not be able to afford or develop.

-informations at cloud are not easily lost also the unlimited storage capacity.

-Scalibility, reliability and efficiency

As the advantages there are disadvantages also to identify in cloud computing.

-This technology requires a constant internet connection

-Also not work well with low-speed connections

-Without the internet connection you cannot access atleast your own documet.

-Lack of control and there may be a challenge in the security and the privacy of Data.

Cloud services will demand expertise in distributed services, procurement, risk assessment and service negotiation areas that many enterprises are only modestly equipped to handle.In the next article we will look in to the services of the cloud computing.                         

Using HTML in creating Web pages.(Basics)
