A massively scalable architecture is defined as a cloud implementation that is either a very large deployment, such as one that would be built by a commercial service provider, or one that has the capability to support user requests for large amounts of cloud resources. An example would be an infrastructure in which requests to service 500 instances or more at a time is not uncommon. In a massively scalable infrastructure, such a request is fulfilled without completely consuming all of the available cloud infrastructure resources. While the high capital cost of implementing such a cloud architecture makes it cost prohibitive and is only spearheaded by few organizations, many organizations are planning for massive scalability moving toward the future.
