aws vpc networking:- in aws vpc networking there are many types of Gateway which we should follow in networking
They are 1. internet gateway 2. NAT gateway
- internet gateway:- it is a scalable , reducent , and highly avilability aws vpc networking allows you to communication between instances in vpc and internet
internet gateway servers have two purposes
- It provides target in your VPC route tables for internet-routable traffic
- to perform network address translation for instances that were assigne public IPv4 addresses.
2. NAT gateway:- enables in instances in a private subnet with the internet connection with the aws or console
Creation of NAT gateway:- for the first creation of the nat gateway we should reside public subnet with the NAT gateway
create a NAT gateway, you must update the routing table that’s associate with one or more of your private subnets to point internet-bound traffic to the NAT gateway.
VPC sharing offers several benefits:-
Separation of duties:- when controlled by vpc structure routing, and IP address, also the allocation point
Ownership:- although owners continue to own resources, also accounts, and security groups
security groups:- in addition with the sharing participants can reference sharing of the security of each other
NAT gateway services provide the availability of better availability, higher bandwidth, and less administrative effort.
