VPC Network
Google Cloud VPC Network:
Google Cloud Networking l Google Cloud VPC Basics:-
— VPC Network is just like your Physical Network except that it is Virtualised within Google Cloud.
— A VPC Network is a global resource that Consists of a list of Regional Virtual Subnetworks in Data Centres, all connected by a global Wide Area Network.
A VPC Network provides:-
- Provides connectivity for your VM, including GKE and app Engine instances.
- Offers Native Internal TCP/UDP Load Balancing.
- Connects to on-premises network using Cloud VPN Tunnels and Cloud Interconnect attachments.
- Distributes traffic from Google Cloud external Load Balances to Backends.
- VPC always lies inside a Project, One project can Contain multiple VPC Network.
- New Project start with a default VPC that has one subnet in each Region.
VPC Networks has following properties:-
— VPC Networks, including their associated routes and firewalls rules are global resources. They are not associated with any particular region or zone.
— Subnets are regional resources. Each Subnet is associated with a region. You can create more than One Subnet per region.
— Each Subnet is having unique network range inside a Project.
— Inside and Outside traffic can be Controlled by firewall rules.
— Resources within a VPC, can communicate with one another by using IPv4 and IPv6 address.
— An Organisation can use shared VPC to keep a VPC network in a Common host Project.
— VPC networks can be Connected to Other VPC networks in different Projects or Organisations by using VPC Network Peering.
— VPC Network do not support Broadcast or Multicast address within the Network.
— Auto Mode VPC networks create Subnets in each region automatically.
— You Cannot Connect directly Auto Mode VPC Network to one another because they uses Same ranges 10.128.0.0/9
Creating Automatic Mode VPC using Console & Cloud-shell:-
Step1. Login to GCP Console:
— VPC Network
— Name — my-auto-vpc
— VPC ULA IPv6 — Disabled
— Subnets — Automatic
IPv4 Firewall Rules — Allow TCP: 22
Dynamic Routing Mode — Regional
MTU — 1460/1500/8896
— Create.
Step2. Go to Compute Engine:
— Create two VM’s in different regions (for example US-Central1 & Asia-southeast-1)
Step3. Do As Below:
— Take SSH of both VM’s and ping each other with their Private IP.
Creating Automatic Mode VPC using Cloud-shell:-
— Here we’ll get command during creation of Automatic VPC via Console
— Just copy and change name accordingly and run it.
