Hence, the given statement that 'Cloud computing uses Server virtualization. ' is TRUE.
The correct option is b. It allows users to use only those applications that are there on their computers. Statement b) b. It allows users to use only those applications that are present on their computers are not true for cloud computing.
Cloud Computing. the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
main poblem with cloud is secuirity and payment. especially in IT services it is very difficult to estimate the cost of the cloud as it involves "pay as use". Scalability is also one of the bigg issue in IT cloud.
2. Cloud is not server virtualization. Despite what many believe, and what many will tell you, the cloud is not the same as next-gen server virtualization. It doesn't surprise me that many believe that by virtualizing their data center they will create a private cloud.
Explanation: Logging, auditing, and regulatory compliance are all features that require planning in cloud computing systems.
Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.
Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services. Cloud infrastructure involves the hardware and software components required for proper implementation of a cloud computing model.

In cloud computing, resources are treated independently; in cluster computing, the resources are seen as a single system. In cloud computing, resources are not as reliable as in cluster computing because cluster computing has redundant nodes for high availability.
