CLOUD COMPUTING Introduction

CLOUD COMPUTING
Introduction: Cloud computing is a type of computing that relies on shared computing resources rather than having local servers or personal devices to handle applications. Simple description is, cloud computing is taking services and moving them outside an organization’s firewall. Applications, storage and other services are accessed via the Web. The services are delivered and used over the Internet and are paid for by the cloud customer on an as-needed or pay-per-use business model.
The U.S. National Institute of Standards and Technology (NIST) defines cloud computing as ” a model for enabling convenient and on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications and services that can be rapidly provisioned and released with minimal management effort or service provider interaction”.And Wikipedia website defines cloud computing as “an Internet based computing, whereby shared resources, software and information are provided to computers and other devices on demand, like a public utility”.
There are benefits in utilizing cloud computing. For one, these remote servers or computers are tasked with all the heavy lifting in terms of storage. As such, there isn’t an unequivocal need to purchase a more powerful and expensive device. The consumer can then utilize these services without breaking the proverbial bank.And Secondly, all that’s required to access cloud computing options is an internet connection.

Having access to cloud computing can be highly beneficial for consumers and businesses. In terms of a consumer, one can upload heavy amounts of music, word documents, and photos without tying up all available data/space on one’s personal device. From a business perspective, the cloud can work wonders when preserving documents and all sorts of significant information from decades of work. Duly, the said devices from a workplace can further be tied together. Co-workers could work together on the same assignment via the functionality of cloud computing.

This makes the remote collaboration easier for the users.
