To satisfy the ever increasing demand for Cloud Computing resources from emerging applications such as Internet-of-Things IoTacademics and industry experts are now advocating for going from large-centralized Cloud Computing infrastructures to micro data centres located at the edge of the network. These micro data centres are often closer to a user geographically and in access latency compared to the centralised cloud data centre. This vision also acknowledges the variation in network latency from an end user to cloud data centre.
Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallels to this concept can be drawn with the electricity grid, where end-users consume power without needing to understand the component devices or infrastructure required to provide the service.
Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualized resources It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.
This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if they were programs installed locally on their own computers.
Most cloud computing infrastructures consist of services delivered through common centers and built-on servers. Clouds often appear as single points of access for consumers computing needs. Commercial offerings are generally expected to meet quality of service QoS requirements of customers, and typically include service level agreements SLAs.
In the traditional model of computing, both data and software are fully contained on the user s computer; in cloud computing, the user s computer may contain almost no software or data perhaps a minimal operating system and web browser onlyserving as little more than a display terminal for processes occurring on a network of computers far away.
A common shorthand for a provided cloud computing service or even an aggregation of all existing cloud services is The Cloud. The most common analogy to explain cloud computing is that of public utilities such as electricity, gas, and water. Just as centralized and standardized utilities free individuals from the difficulties of generating electricity or pumping water, cloud computing frees users from certain hardware and software installation and maintenance tasks through the use of simpler hardware that accesses a vast network of computing resources processors, hard drives, etc.
The sharing of resources reduces the cost to individuals. The phrase cloud computing originated from the cloud symbol that is usually used by flow charts and diagrams to symbolize the internet. The principle behind the cloud is that any computer connected to the internet is connected to the same pool of computing power, applications, and files.
Users can store and access personal files such as music, pictures, videos, and bookmarks or play games or use productivity applications on a remote server rather than physically carrying around a storage medium such as a DVD or thumb drive.
Almost all users of the internet may be using a form of cloud computing though few realize it. Those who use web-based email such as Gmail, Hotmail, Yahoo, a Company owned email, or even an e-mail client program such as Outlook, Evolution, Mozilla Thunderbird or Entourage that connects to a cloud email server.
Hence, utilizing desktop applications to connect to your cloud email, is still considered a cloud application. Related cloud-computing-research-paper-list Definition of Cloud Computing Cloud computing is becoming one of the next IT industry buzz words: This is again a central processing use case.
Similar scenario occurred around 50 years ago: Until 20 years ago when personal computers came to us, data and programs were mostly located in local resources. Certainly currently the Cloud computing paradigm is not a recurrence of the history. Nowadays the Cloud computing comes into fashion due to the need to build complex IT infrastructures.

Computing resources and other hardware are prone to be outdated very soon. Therefore outsourcing computing platforms is a smart solution for users to handle complex IT infrastructures.
