Answer 1

ANSWER: Cloud services usually have the following features in common:
* on-demand-Services, applications, and storage in a cloud are available to users at any time, upon the user's request.
* cross-platform-Clients of all types, including smartphones, laptops, desktops, thin clients, and tablet computers, can access services, applications, and storage in a cloud, no matter what operating system they run or where they are located, as long as they have a network connection.
* consolidated-Host computers in the cloud provide multiple virtual machines, resources such as disk space, applications, and services that are pooled, or consolidated. For example, a single cloud computing provider can host hundreds of websites for hundreds of different customers on just a few servers. This is called a multi-tenant service model.
* metered-Everything offered by a cloud computing provider, including applications, desktops, storage, and other services, is measured. A provider might limit or charge by the amount of bandwidth, processing power, storage space, or client connections available to customers.
* elastic-Services and storage capacity can be quickly and dynamically-sometimes even automatically-scaled up or down. In other words, they are elastic. The elasticity of cloud computing means that storage space can be increased or reduced, and that applications and clients can be added or removed, as needed. For example, if your database server in the cloud is running out of hard disk space, you can upgrade your subscription to expand it yourself, without your having to alert the service provider. The amount of space you can add and the flexibility with which it can be added depend on your agreement with the service provider.
