How to Implement Region Failover Config in Python with Primary and Secondary Mock

import time

class RegionFailoverConfig:
    def __init__(self, primary, secondary):
        self.primary = primary
        self.secondary = secondary
        self.active = primary
        self.failover_count = 0
        self.healthy = True

    def check_health(self):
        """Mock health check - returns True if active region is alive."""
        return self.healthy

    def failover(self):
        """Switch active region to the secondary if primary fails."""
        if not self.check_health():
            self.active = self.secondary
            self.failover_count += 1
            return f"Failover triggered -> Active region: {self.active}"
        return f"No failover needed - Active region: {self.active}"

    def recover(self):
        """Recover primary and switch back if it's healthy."""
        self.healthy = True
        self.active = self.primary
        return f"Recovered -> Active region: {self.active}"


if __name__ == "__main__":
    config = RegionFailoverConfig(primary="us-east-1", secondary="eu-west-1")

    print(config.failover())   # No failover (healthy)
    config.healthy = False     # Simulate primary outage
    print(config.failover())   # Failover to secondary
    print(config.failover())   # No failover (secondary healthy)
    print(config.recover())    # Recover primary
    print(f"Total failovers: {config.failover_count}")
