Amazon VPC: A Quick Introduction
A simple introduction to Amazon VPC and the key networking components used to connect AWS resources.
Amazon VPC (Virtual Private Cloud) lets you create a private network for your AWS resources.
With a VPC, you can control how resources such as EC2 instances communicate with each other and with the internet.
Key Components
- Subnets: Divide a VPC into smaller networks. They can be public or private.
- Route Tables: Control where network traffic is sent.
- Internet Gateway: Allows resources in a public subnet to communicate with the internet.
- Security Groups: Act as virtual firewalls and control inbound and outbound traffic.
For example, a typical application can have its web servers in a public subnet while keeping databases in private subnets.
Conclusion
VPC is the foundation of networking in AWS. Understanding its basic components helps you build applications that are more secure and easier to manage.
