Setting up AWS Networking
Using the AWS Management Console
This article explains how to set up a basic AWS Virtual Private Cloud (VPC) network using the AWS Management Console. We'll cover key networking components such as subnets, internet gateways, NAT gateways, and route tables.
Setting up AWS Networking using the AWS Management Console
Subnets (Public and Private)
Public subnets are connected to the internet gateway, allowing instances launched within them to access the internet directly. Private subnets, on the other hand, do not have direct internet access and require a NAT gateway or VPN for outbound connectivity.
Public subnet: Access to internet. Private subnet: No direct internet access.
Internet Gateways and NAT Gateways
An internet gateway is a required component for your VPC to communicate with the internet. NAT Gateways enable instances in private subnets to access the internet without exposing their private IP addresses.
Internet Gateway: Connects VPC to internet. NAT Gateway: Enables outbound internet access from private subnets.
Route Tables and their importance
Route tables control how network traffic is directed within your VPC. Each subnet is associated with one or more route tables, specifying the destination and the next hop (e.g., internet gateway, NAT gateway).
Route Table: Controls network traffic within the VPC.
Summary
- Public subnets provide direct internet access.
- Private subnets require NAT Gateways for internet access.
- Route tables are crucial for network routing.
- AWS Management Console provides a user-friendly interface for VPC configuration.
