This image shows an Apache Cassandra cluster consisting of three non-seed nodes and three seed nodes running on Oracle Cloud Infrastructure compute instances distributed across the fault domains within an availability domain in a region. The image also shows Cassandra Gossip connections among all the nodes, which are attached to a single regional subnet 10.0.1.0/24 in the VCN 10.0.0.0/6. Security lists are used to control network traffic to and from the subnet. A route table & an internet gateway are included for connectivity to the public internet.
