scaling on demand

Explanation:

Cloud computing is the on demand real time delivery of computing resources such as data storage, software’s, and server to subscriber using internet as the medium. A subscriber need not have any IT infrastructure at its location to use computer computing services. They can subscribe for the computing services as and when required and use it through internet only. It helps in flexibility of resources i.e use only those resources and pay for those resources only which one has used. One of the advantages is scalability meaning that as the business grows, need for bigger IT infrastructure grows, at that time one can simply subscribe for more services and pay for the added computing resources.

problem stated mentions about matching resource at any given time which is simply scaling up the resources based on need and demand hence it can be concluded that scaling on demand is most suitable answer.
