Standard Mode vs AutoPilot Mode

Network

VPC-native cluster (default)

  • A cluster that uses alias IP address ranges is called a VPC-native cluster.

  • Take advantage of VPC Subnet Secondary IPv4 ranges (aka IP alias).

    • Nodes use the subnet’s primary IP range.
    • Pods use one of the subnet’s secondary IP ranges.
    • Services use another secondary IP range.

  • Example VPC subnets in default VPC network:

VPC Native Network for default GKE cluster .

  • Benefits:
    • Pod IP address ranges do not depend on custom static routes. They do not consume the system-generated and custom static routes quota. Instead, automatically-generated subnet routes handle routing for VPC-native clusters.
    • You can create firewall rules that apply to just Pod IP address ranges instead of any IP address on the cluster’s nodes.
