The invention belongs to the field of cloud computing, and especially relates to a cloud computing framework method and system based on big data. The cloud computing framework method based on the big data comprises following steps of firstly, carrying out lightweight virtualization processing to each cloud computing node, thus realizing pooling of bottom layer resources and constructing a management layer; secondly, framing a big data platform on the virtualized nodes; constructing a service layer by utilizing the advantages of distributed storage and parallel computing of the big data; moreover, carrying out logic judgment to demands of a user by an application layer; and transmitting data computing and reading instructions to the service layer for task processing through an interface in real time. According to the method and the system provided by the invention, a cloud computing node operation system is virtualized by utilizing a Docker engine and an LXC mechanism; the virtualization is lightweight virtualization; the bottom layer resources are virtualized rapidly; moreover, isolation performance and mobility among the virtualized resources are high; the resource utilization rate is improved; and the resource management complexity is reduced.
