A dedicated master node handles cluster administration but does not store any data or respond to data upload requests. By offloading cluster management duties, master nodes increase the dependability of your domain. In addition to all other node types, you pay for each dedicated master node on an hourly basis. A dedicated cluster is a finished private cloud exclusively for you. Web and database servers, load balancers, and other components can be included to satisfy your requirements. Redundancy and scalability are built right in to handle traffic spikes.
Final cut: A dedicated node is a single computer set up to participate in a blockchain network as a full or archive node. It stores the entire blockchain data and can be used to get that data via JSON RPC interface. On the other hand, a dedicated cluster is a group of blockchain nodes working together for a more robust and scalable Web3 infrastructure. A dedicated cluster offers advanced features such as load balancing, high availability, scalability and adjustable performance compared to a single dedicated node. The choice between a dedicated node and a dedicated cluster depends on the organization's specific needs and resources.
