On-demand self-service Broad network access Resource poolingRapid elasticityMeasured service Five Essential Cloud Characteristics Allows business units to get the computing resources they need without having to go through IT for equipment. Enables applications to be built in ways that align with how businesses operate today - mobile, multi-device, etc. Allows for pooling of computing resources to serve multiple consumers. Allows for quick scalability or downsizing of resources depending on demand. Business units only pay for the computational resources they use. www.engineersportal.in

16. Conclusion Companies have to pick and choose and be careful with what data they allow to be out there in a cloud. Cloud computing can be a useful resource to help companies save money but can also have downfalls. As companies perfect their cloud computing services, I think that more companies will be open to using these services. This service will provide new inventive ways to use computers and provide services. www.engineersportal.in
