Configuring a VPC and subnets in AWS can seem a bit daunting at first, but once you understand the core components, it gets easier. Here’s a quick rundown of the process:
Create a VPC:
You start by creating a Virtual Private Cloud (VPC), which essentially acts as your network in the AWS cloud. During the VPC creation, you’ll define the CIDR block (e.g., 10.0.0.0/16), which will allocate a range of IP addresses for your VPC. Set up Subnets:
Subnets allow you to organize your resources within the VPC. You can create public subnets (for resources that need internet access) and private subnets (for backend resources). When creating subnets, you’ll specify which Availability Zone (AZ) they will reside in, which can help with high availability. Internet Gateway & Routing:
Attach an Internet Gateway to your VPC to enable communication with the internet. Then, set up routing rules, ensuring that the public subnets have a route to the Internet Gateway for internet access. Security Groups:
Security Groups act as virtual firewalls for your resources. You’ll want to configure them to allow the necessary inbound and outbound traffic. If you’re new to AWS, it can help to see a hands-on demonstration of how to set this up. I’ve created a video tutorial where I walk through the entire process of setting up a VPC with subnets, security groups, and routing, which could be helpful if you want a step-by-step visual guide.
