Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet and temporarily stored on the user's computer (client) including the desktop, tablet computers, notebooks, wall computers, handhelds, sensors, monitors, etc. .

Cloud computing will soon become reality, and this will force the IT professionals to quickly adapt the meaning of this technology. As a result of socio-economic situation which continues to experience very rapid revolution that gave birth to cloud computing, where technology is needed for speed and reliability are more than technology will advance so that the technology would eventually reach the level of investment in terms of cloud service is quick and easy.

Cloud was present before us today, but what is cloud? where tujuanya? and what are the risks? and how IT organizations prepare for this? That question will be present at least by some practitioners or IT enthusiasts, the dasaranya Cloud computing is to use Internet-based services for support to business process. Cloud service usually has several characteristics, including:
Very quickly deployed, so that means instant for quick implementation.

    * Later start-up costs of this technology may be very low or absent and no capital investment.
    * Cost of service and usage will be based on a commitment that does not fix.
    * This service can easily upgrade or downgrade quickly without a Penalty.
    * This service will use the method of multi-tenant (Many customers within a platform).
    * The ability to customize the service will be limited.
Cloud technology will give the contract to the user for the service on three levels:

    * Infrastructure as Service, this includes Grid for virtualized server, storage & network. Examples such as Amazon's Elastic Compute Cloud and Simple Storage Service.
    * Platform-as-a-service: it focuses on the application which in this case allows developers to not think about the hardware and keep its focus on application development without having to worry about operating systems, infrastructure scaling, load balancing and so on. Examples that have been include Force.com and Microsoft's Azure investments.
    * Software-as-a-service: This focuses on the application premises Web-based interface that is accessed through Web Services and Web 2.0. example is Google Apps, SalesForce.com and social networks like FaceBook application.
Some investors are still trying to explore the adoption of this technology cloud to be business as Amazon and Google already has a special offer on for the cloud, Microsoft and IBM have also invested millions of dollars for this.
Judging from this trend we can predict the future, the technology standards will be simpler because of the availability of many cloud services.
