WebTo address this, FASTER supports asynchronous non-blocking checkpoint-based recovery. The user invokes a checkpoint periodically. Every new checkpoint persists (or makes durable) the effects of all operations (Read, Upsert, RMW) until that point. FASTER allows clients to keep track of which operations have persisted using a session-based API.

This internal load balancer is configured with HA Ports rules, so that every TCP/UDP port is redirected to the NVA instances.
