Recommended: Cloud computing is the delivery of computing resources over the internet based on cloud consumer demand

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.
Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of resources and services over the internet. Cloud is a huge group of interconnected systems, which is a major change in how we store the large information and run application in time.
Cloud computing is a shared pool of configurable and well advanced computing resources, on-demand network access and is provisioned by the cloud service provider. The main advantage of cloud computing is a cost effective, Cloud computing is used by many software IT industries.
Clouds have a large pool configured easily available resources which are well accessible and usable resources such as hardware like desktops, hard disks, platform and services. These resources in the cloud can dynamically reconfigured adjust to variable scale, allowing for optimum resource utilization.
Cloud computing is a new dimension information technology (IT) and paradigm, which main aims to provide cost effective, reliable, customized and well guaranteed dynamic computing environment on “Pay-per-use” basis for the clients or end users....

...equire fewer maintenance because there is no need to install or upgrade software or hardware each and every time. Cloud mainly improves compatibility between the operating systems. It requires always on and high-speed internet connectivity for a single accessing also each and every time.

In cloud sometimes the data stored in the cloud server is so important that the clients who store their important data must ensure that it is not lost or corrupted. While in cloud it is easy to check the data integrity that whether their data is correct or not after completely downloading the outsourced data to be checked, downloading huge amounts of data just for checking data integrity is a waste of time for the client communication bandwidth along with this it also brings new challenging security vulnerability threats towards users outsourced data in the cloud computing system

    Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.

    Cloud Computing is more of a virtual computing interface, in which the environment where users work is not actually connected to a single machine. Cloud Computing involves the leasing of computing infrastructure and software via the internet, so that the virtual environment is completely maintained at a remote location. The users do not know where the infrastructure is or the paths their data takes. Because, of this, Cloud computing allows for greater accessibility, since users do not have to understand the tools and programs that create the interface whereas in Autonomic computing, at its most basic level, requires an understanding of the infrastructure

  • Cloud Computing Security

    Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.

    The fundamental idea behind a virtual machine is to remove the hardware of a single computer and make it a self-contained operating environment that behaves as it is a separate computer. Essentially, the virtual machine is software that executes an application and isolates it from the actual operating system and hardware. CPU scheduling and virtual-memory techniques are used so that an operating system can create the illusion that a process has its own processor with its own (virtual) memory. The virtual machine provides the ability to share the same hardware yet run several different operating systems concurrently, as shown in Figure 2-11.
