Cloud Computing?

CLOUD COMPUTING

Let's Start With the Cloud Computing--

Cloud Computing provides us means by which we can access the applications as utilities over the internet. It allow us to create, configure and customize the business applications online.

CLOUD  + COMPUTING

CLOUD-->Refers to a Network or Internet. Cloud Provide Services over public and private networks, i.e; WAN, LAN and VPN.

Applications such as E-mail, Web conferencing, Customer relationship management(CRM) execute on cloud.

We can store our data over the cloud because it's provides/offer an online data storage, infrastructure and application.

 

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort.

Proponents claim that cloud computing allows companies to avoid upfront infrastructure costs, and focus on projects that differentiate their businesses instead of on infrastructure. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand. Cloud providers typically use a "pay as you go" model. This can lead to unexpectedly high charges if administrators do not adapt to the cloud pricing model.

The present availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture, and autonomic and utility computing have led to a growth in cloud computing. Companies can scale up as computing needs increase and then scale down again as demands decrease.

Cloud computing has now become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability, accessibility as well as availability. Cloud vendors are experiencing growth rates of 50% per annum.^[11] But due to being in a stage of infancy, it still has some pitfalls which need to be given proper attention to make cloud computing services more reliable and user friendly.
