VPCs Flashcards
What are VPCs?
Virtual Private Clouds. Enables you to launch your resources in a private network most likely for what you’d have in your physical data center but with the vantage that it will scale based on your needs.
What are subnets?
Subnets are isolated local networks inside the VPC’s that are used to launch our resources. For instance, you can’t directly apply an EC2 instance in a VPC, we need a subnet for it.
What is routing in VPCs?
it defines the traffic between subnets and in/out the public internet.
How can I configure my security groups to allow communication with the public internet?
By allowing traffic through ports, protocols, or IPs
What is a route table?
A route table is a set of rules called routes that are used to determine where traffic from subnet or gateway is directed.
