Node in Cloud Computing is a connection point, either a redistribution point or an end point for data transmissions in general. Node in Cloud Computing is not a neologism. Node is actually a terminology that is derived from Networking. From Networking it was used in Grid Computing, then Virtualization and from from Virtualization in Cloud Computing.
Node in Cloud Computing can be confusing
If only Node is mentioned, it might not be synonymous with Node in Cloud Computing. This word Node we use in Cloud is of Networking. There is Goal node, which denotes criteria for success or termination of a job. Mesh node is used in Mesh Network, related to network transceiver. In Heuristical artificial intelligence, there is also a Node. In medical Science, there is also node with at least 3 meanings. Good example is Lymphatic Node.
More confusing is, Node exists in pure Computer Science.
The Basic Question : What is Node in Cloud Computing
Cloud Computing or Cloud in general term, is a fine tuned distributed system from end users’ point of view, Node in Cloud Computing are servers. Node in Cloud Computing may sometimes actually be a virtual node for circumventing heterogeneity of the nodes. But in general, Node in Cloud Computing means a physical server or another cloud that itself consists of nodes.
Node in Cloud Computing has special importance, the individual computers on the cloud system which are by architecture or geographically are at distant periphery of the internal network keeping the connection within the cloud nodes, often connect transiently to one or more clouds. The Node in Cloud Computing are called end nodes. Typically, within the cloud computing infrastructure, the individual like you or me connect with the end node. From security point of view these End Node in Cloud Computing has the highest risk to face various attacks, which can ultimately collapse the whole system.
