All Google Cloud Bigtable client requests go through a front-end server ______ they are sent to a Cloud Bigtable node.
Answer(s): A
In a Cloud Bigtable architecture all client requests go through a front-end server before they are sent to a Cloud Bigtable node.The nodes are organized into a Cloud Bigtable cluster, which belongs to a Cloud Bigtable instance, which is a container for the cluster. Each node in the cluster handles a subset of the requests to the cluster.When additional nodes are added to a cluster, you can increase the number of simultaneous requests that the cluster can handle, as well as the maximum throughput for the entire cluster.
