Basically, the runtime node features the Java Virtual Machine (JVM) and inflows run throughout the JVM node. It regulates the audit log and processes messages. Most frequently, it interacts with external systems through the load balancer.
On the other hand, the tenant management nodes help read the data and manage the runtime node that the runtime node is liable for writing. This node offers a front-end editor to developers and administrators performing a variety of tasks, like user creation and role management. Moreover, it acts as an agent between varying runtime parts of human users and CPI.
