CLOUD COMPUTING

What does cloud computing imply ?

                                                Cloud computing is computing in which huge groups of remote servers are networked to permit centralized data storage and online access to computer services or resources with five special characteristics : On-demand self-service , Broad network access , Resource pooling , Rapid elasticity and Measured service.

                                                Cloudcomputing/Salesforce includes saving and gathering data and programs over the Internet instead of your computer's hard drive.

 Details on Cloud Computing :

                                                In a cloud computing system, there's a significant distribution of workload. So the computers no longer have to do all the heavy lifting when it comes to running applications as it is handled by the multiple network of computers that make up the cloud. Cloud computing systems require at least twice the number of storage devices it requires to keep all its clients' information stored.

                                                Cloud computing is traditionally defined as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.

Features / Advantages /Merits of Cloud computing :

       1.    Agility 

       2.   Cost reductions

       3.   Device and location independence

       4.   Maintenance

       5.   Multitenancy : It enables sharing resources and costs across a large pool of users thus allowing for 

6. Centralization of infrastructure in locations with lower costs .
7. Peak-load capacity increases (users need not engineer for highest possible load-levels).
8. Utilisation and efficiency improvements for systems that are often only 10–20% utilized.

     9.   Performance :  Performance is consistent and loosely coupled architectures are constructed using web services as the system interface

    10.  Productivity :  Productivity is increased as multiple users can work on the same data at a time, instead of waiting till the time it is saved and emailed. As a result of which time may be saved as neither the users need to install application software upgrades to their computer nor the information is to be re-entered when fields are matched.

    11.  Reliability :  Improves with the use of multiple sites, which makes well-designed cloud computing suitable for business continuity and disaster recovery

    12.  Security :  Providers are able to devote resources to solving security issues that many customers cannot afford to tackle

    13.  Hardware and software demands on the user's side decrease.

    14.  To do this, cloud computing uses networks of large groups of servers typically running low-cost consumer PC technology with specialized connections to spread data-processing trials across them. This shared IT infrastructure contains large pools of systems that are linked together . Usually, virtualization methods are used to maximize the power of cloud computing.

   15.  Focuses on maximizing the effectiveness of the shared resources.

   16.  Cloud computing, or in simpler shorthand just "the cloud ,  allows companies to avoid upfront groundwork costs, and concentrates on projects that differentiate their businesses instead of on            infrastructure/ground work.

   17.  Cloud computing allows enterprises to get their applications up and operating faster, with better manageability and reduced maintenance, and thus enables IT to more rapidly and quickly adapt resources to meet fluctuating and unpredictable business demand.

How cloud computing works ?

            The aim of cloud computing is to implement traditional supercomputing, or high-performance computing power, normally used by military and research facilities, to perform tens of trillions of computations per second, in consumer-oriented applications such as financial portfolios, to deliver personalized information, to provide data storage or to power large, immersive computer games. 

            To do this, cloud computing uses networks of large groups of servers typically running low-cost consumer PC technology with specialized connections to spread data-processing trials across them. This infrastructure consist of  huge ocean of systems that are coupled together. Many times,  cloud computing techniques are used to maximize the power of cloud computing.

Market value for Cloud computing :

                 A recent report from market research firm Markets and Markets reveals that the cloud market is expected to grow to $121 billion dollars by 2015: a 26% compound annual growth rate from the $37 billion value in 2010 .

          The worldwide cloud computing market will grow at a 36% compound annual growth rate (CAGR) through 2016, reaching a market value of $19.5B by 2016.
