22. Edge Cases
ND0063 C1 L1 17 Edge Case- [#1] Video
AWS networking does have some limitations that your own data center network would not.
- You cannot use multicast in a VPC
- You cannot put network cards into "promiscuous" mode to sniff ethernet packets.
- There are some restrictions on opening up ports for SMTP
- You cannot have network scans run against your account without discussing with AWS
You can connect VPCs together to enable:
- Cross VPC connections
- Cross region connections
- Cross account connections
Intuition
SOLUTION:
- Creating a permanent connection to an existing datacenter
- Connecting two of your VPCs
- Connecting two VPCs in different regions
- Connecting two VPCs in different AWS accounts
