1. A method, implemented on at least one machine, each of the at least one machine having at least one processor, storage, and a communication platform connected to a network for automatically deploying a plurality of distributed application stacks on a target machine, the method comprising the steps of: in each of a plurality of clusters, deploying at least one cluster-side software artifact of one of the plurality of distributed application stacks, wherein the at least one cluster-side software artifact is associated with a version that uniquely identifies the distributed application stack which the at least one cluster-side software artifact belongs to; creating a plurality of virtual environments on the target machine through which a user has access to the plurality of clusters remotely, wherein the plurality of virtual environments are isolated from each other; in each of the plurality of virtual environments, deploying at least one target-side software artifact of one of the plurality of distributed application stacks, wherein the at least one target-side software artifact is associated with a version that uniquely identifies the distributed application stack which the at least one target-side software artifact belongs to; and associating each of the plurality of virtual environments with one of the plurality of clusters by matching the version of the at least one target-side software artifact deployed in the virtual environment with the version of the at least one cluster-side software artifact deployed in the cluster, wherein deploying at least one target-side software artifact comprises: receiving an instruction to be used to direct the target machine to deploy the at least one target-side software artifact in the virtual environment; identifying the at least one target-side software artifact from the plurality of target-side software artifacts for the virtual environment based on the instruction; determining the version of the at least one target-side software artifact for the virtual environment based on the instruction; fetching the at least one target-side software artifact in the determined version to the target machine; and installing the at least one target-side software artifact in the determined version in the virtual environment of the target machine.
