Managing keys for SSH access

6. Managing and monitoring network operations

Logging and monitoring with Stackdriver or GCP Console

Managing and maintaining security. Considerations include:

Diagnosing and resolving IAM issues (shared VPC, security/network admin)
Firewalls (e.g., cloud-based, private)

Maintaining and troubleshooting connectivity issues. Considerations include:

Draining and redirecting traffic flows
Monitoring firewall logs
