Review of GCP Networking Services

Review of Key Networking Concepts

Virtual private cloud
- Global resource
- Create subnets in regions (in all by default)
- Resources can communicate using private IP adressing
- You can share VPCs within organizations
- You can peer VPCs across organizations
Virtual private network
- Links VPC networks to on-premise networks
- Implemented with IPSec
- Traffic routed over public internet (encrypted)
- Up to 3 Gbps
Cloud interconnect
- Google networking service
- Connect directly (> 10 Gbps, < 100 Gbps)
- Connect through third party (> 50 Mbps, < 10 Gbps)
Peering
- Low level network connection
- Linking networks
- Traffic routed using Border Gateway Protocol
- Does not use GCP objects
Load balancers
- Global or regional
- Internal or external
- Traffic type
  - Global (all external)
    - HTTPS
    - TCP
    - SSL
  - Regional
    - Internal TCP/UPD
    - Network TCP/UPD
