AWS Private Virtual Cloud


 






AWS VPC integrates with numerous integrated services.




·       Each AWS account can create multiple vpcs

·       A VPC defines an IP address space that is then divided by subnets.

·       Subnets are deployed within the availability zones. U can create many. Fewer is recommended to limit the network complexity.

·       You can configure route tables to the subnets. - to control the traffic between subnet and the internet.

·       By default all subnets in vpc can communicate with each other.

·       2 types of subnets. Public has direct access to the internet. Private doesn’t have direct access.

·       To make the subject public you have to attach the gateway to the vpc and update the route table.

·       EC2 instance also needs public ip to route to internet gateway.

·       Example have HA

  • o   Private subnet is isolated from the internet.
