Cloud computing, also known as 'on-demand computing', is a kind of Internet-based computing, where shared resources, data and information are provided to computers and other devices on-demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources.Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers. It relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
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. 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

The benefits of Cloud Computing as well as the application of a day in the life – day
After a brief definition of the translation above is certainly the use of technology with the system makes it easy for users in addition to cloud fairly in terms of the efficiency of the data, as well as cost savings. The following benefits are benefits that can be learned through cloud-based system technology.
1. All Data stored on a Centralized Server
One of the advantages of cloud technology is allowing users to save data is centralized in one server based on services provided by providers of Cloud Computing itself. In addition, users also need not bother bother again provides infrastructure such as data centers, media storage/storage etc because all available virtually.
2. Data Security
Security of user data can be securely stored via the server provided by your service provider Cloud Computing such as guarantees, warranties ISO technology platforms, personal data, etc.
3. high flexibility and scalability
Cloud technology offers versatility with ease of data access, when and wherever we are with a note that the user (user) to connect to the internet. In addition, users can easily increase or decrease the data storage capacity without the need to purchase additional equipment such as a hard drive. Even one of the IT world notable practitioners, the late Steve Jobs says that buying the physical memory to store data such as the hard drive is useless if we can keep him virtually/via the internet.
4. Long-term investments
Cost savings will be the purchase of inventory, such as infrastructure, hard drive, etc. will be reduced because the user will be charged the regular compensation per month in accordance with the agreed service package with service providers Cloud Computing. The cost of royalties upon software license can also be reduced since all have been run through Cloud-based computing.
The application of Cloud Computing has been done by some of the world's renowned IT companies such as Google through the Google Apps Drive, IBM via the Blue Cord Microsoft Initiative, through its operating system-based Cloud Computing, Windows Azure, etc. On the national scene its own Cloud application of technology can also be seen through the use of Point of Sale/cash register program.
One of the companies that develop products based on a Cloud is DealPOS. The working method of Point of Sale (POS) is to distribute retail sales data has been input by the cashier to retail store owners over the internet regardless of where located shop owners. In addition, well-known national telecommunications company, Telkom also develop Cloud-based computing systems via Telkom Cloud VPS with Telkom and Telkom Collaboration directed to SME customers (small-medium).

The Workings Of Cloud Computing Systems
Cloud system of work using the internet as a server in the process data. This system allows users to log into the internet connected to the program required to run applications without installation. Infrastructure such as data storage media and also the instructions/commands from the user stored virtually through the internet network command then the command – proceed to application servers. After orders are received at the server application then the data processed and the final user will be presented with a page that has been updated in accordance with the instructions received earlier so that consumers can feel its benefits.
For example through the use of email like Yahoo or Gmail. Data on multiple servers are integrated globally without having to download any software to use it. Users require only an internet connection and all data maintained directly by Yahoo and Google. Software and also the memory over the user data are not at the computer but integrated directly through the Cloud system using a computer connected to the internet.
