Study Notes

AWS Cloud Networking

Virtual Private Cloud (VPC)

  • A virtual private cloud (VPC) is a virtual network dedicated to your AWS account, allowing for customized networking configurations.
  • Supports IPv4 and IPv6 and allows you to create a virtual private cloud (VPC) with a range of IP addresses.

Subnets

  • A subnet is a range of IP addresses in your VPC, allowing for organized and isolated networks within the VPC.
  • Multiple subnets can be created within a VPC, and each subnet must be a subset of the VPC's IP address range.
  • Supports public and private subnets, offering flexibility in network architecture.

Route 53

  • Route 53 is a highly available and scalable Domain Name System (DNS) service, allowing you to register domain names and route internet traffic to your resources.
  • Supports health checking, traffic flow control, and domain name registration.

Elastic IP Addresses

  • Elastic IP addresses are static, public IP addresses that can be allocated to an instance or a network interface.
  • Supports IPv4 and IPv6, and allows you to maintain a consistent IP address even if the underlying instance is replaced.

Elastic Load Balancer (ELB)

  • Elastic Load Balancer (ELB) is a load balancer that automatically distributes incoming traffic across multiple instances.
  • Supports multiple protocols (HTTP, HTTPS, TCP, and UDP), health checking, and auto scaling.

Network Access Control Lists (NACLs)

  • NACLs are a set of rules that control incoming and outgoing traffic at the subnet level.
  • Supports allow and deny rules for specific protocols and ports, and are evaluated in order with the last rule being the default deny rule.

Security Groups

  • Security Groups are a set of rules that control incoming and outgoing traffic at the instance level.
  • Supports allow rules for specific protocols and ports, and are evaluated in order with the last rule being the default deny rule.

Direct Connect

  • Direct Connect is a dedicated, high-speed network connection from your premises to AWS.
  • Supports multiple connections and locations, and allows you to bypass the internet and establish a secure, private connection to AWS.

VPN

  • VPN is a secure, dedicated network connection from your premises to AWS over the internet.
  • Supports multiple connections and locations, and allows you to establish a secure, private connection to AWS over the internet.
