Vpc Peering Full Mesh
You can use vpc peering to create a full mesh network that uses individual connections between all networks.
Vpc peering full mesh. You can create vpc peering between your vpc with the vpc in the same region. There are two broad architectures with transit vpcs. The choice of which to use depends on the use case.
The accepter vpc can be owned by you or another aws account and cannot have a cidr block that overlaps with the requester vpc s cidr block. Vpn tunnels between vpcs in different aws regions are arranged in a full mesh architecture where every vpc is connected to every other vpc though an ipsec tunnel. Hub and spoke and fully meshed.
Vpc peering offers point to point network connectivity between two vpcs. Since a full mesh connectivity is created between vm instances subnets in the peered vpc networks can t have overlapping ip ranges as this would. With vpc peering you connect your vpc to another vpc.
You have a vpc peering connection pcx 11112222 between vpc a and vpc b which are in the same aws account and do not have overlapping cidr blocks. You can create vpc peering between your own vpc with the vpc in the same region or a different region or with other vpcs in a different aws account in a different region. Aws create peering connection by using the existing infrastructure of the vpc.
The owner of the requester vpc sends a request to the owner of the accepter vpc to create the vpc peering connection. Vpc peering is not based on a standard protocol like bgp or ipsec. Amazon vpc peering enables the network connection between the private vpcs to route the traffic from one vpc to another.
A full mesh of 30 vpc peers mean 435 peering connections. Two vpcs peered together. Not only that but vpc peering only works between aws vpcs.
