• Cloud DNS

Enabling other network services. Considerations include:

• Enabling private API access
• Canary (A/B) releases
• Health checks for your instance groups
• Distributing backend instances using regional managed instance groups

4. Implementing hybrid interconnectivity

Configuring interconnect. Considerations include:

• Virtualizing using VLAN attachments
• Partner (e.g., layer 2 vs. layer 3 connectivity)
• Bulk storage uploads

Configuring a site-to-site IPsec VPN (e.g., route-based, policy-based, dynamic or static routing).

Configuring Cloud Router for reliability.

5. Implementing network security

Configuring identity and access management (IAM). Tasks include:

• Viewing account IAM assignments
• Using pre-defined IAM roles (e.g., network admin, network viewer, network user)
• Defining custom IAM roles
• Assigning IAM roles to accounts or Google Groups

Configuring Cloud Armor policies. Considerations include:

• IP-based access control

Configuring third-party device insertion into VPC using multi-nic (NGFW)

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:

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

Maintaining and troubleshooting connectivity issues. Considerations include:

• Cross-connect handoff for interconnect
• Monitoring ingress and egress traffic using flow logs
• Troubleshooting Cloud Router BGP peering issues
• Identifying traffic flow topology (e.g., load balancers, SSL offload, network endpoint groups)
• Draining and redirecting traffic flows
• Managing and troubleshooting VPNs
• Monitoring firewall logs

Monitoring, maintaining, and troubleshooting latency and traffic flow. Considerations include:

Network throughput and latency testing Routing issues Tracing traffic flow

7. Optimizing network resources

Optimizing traffic flow. Considerations include:

• Expanding subnet CIDR ranges in service
• Global vs. regional dynamic routing
• Load balancer and CDN location
• Accommodating workload increases (e.g., autoscaling vs. manual scaling)

Optimizing for cost and efficiency. Considerations include:

• Cost optimization (Network Service Tiers, Cloud CDN, autoscaler [max instances])
• Automation
• VPN vs. interconnect
• Bandwidth utilization (e.g., kernel sys tuning parameters)
