The basic characteristics of Cloud computing mentioned below:

• Scalability: Infrastructure capacity scale up for traffic spikes in real time
• Resiliency: Cloud providers have MIRRORED images in more than one location to minimize downtime in the event of a disaster. This type of resiliency can give businesses the SUSTAINABILITY they need during unanticipated events.
• On-demand self-service: Self service portal allowing cloud end users to provision compute, network, storage and DATABASES services any time any where without human intervention automatically.
• Broad network ACCESS: Cloud services are accessible over internet from any where any time. End users can connect to cloud services using laptop, tab or mobile phones over internet.
• Resource pooling: Foundation of Cloud service model is multi tenancy to enable sharing of resources amongst end users of different organization scattered over multiple region. Clients are free to choose compute, storage, network, database resources available at many location depending upon their business function. The cloud service provider Data centre is located all over the globe.
• Rapid elasticity: Resource provision to meet business function as per demand can be scale up and scale down rapidly and elastically as resource is available for usage appear to be unlimited and can be purchased in any quantity at any time.
• Measured Service: The services or resources used by users are measured CORRECTLY and displayed in dash board of cloud portal to enable users to track their consumption pattern against every resource and to keep a tab on cost on resource consumption.
