An elastic node is highly scalable public network node infrastructure accessed through your exclusive endpoint. With an elastic node, you pay for JSON-RPC requests to the node and do not pay for the compute and storage resources used by the node.
A dedicated node is a public network node deployed exclusively for you. With a dedicated node, you pay for the compute and storage resources used by the node and do not pay for JSON-RPC requests to the node.
In offering two options, Chainstack offers great flexibility in choosing the right node type for your requirements.
