What is unique about the Swarm architecture that simplifies

Swarm's core design is to be self-managing and self-healing. Swarm sends client requests to nodes that are best suited to handle requests and constantly checks existing content. These checks are done to ensure that the correct numbers of replicas exist and that they are optimally distributed across the cluster.

Secondly, Swarm is a massively scalable cluster. Nodes may be added to Swarm clusters one or more at a time and the coordination with the existing nodes is handled automatically by Swarm without administrator interaction.
