🚀Day 18 - AWS Networks: Taking a Look at VPC Diagrams and CIDR⭐

✅Key concepts of VPC diagrams and CIDR notation to simplify understanding.

➡ VPC (Virtual Private Cloud): Representing your isolated network segment within AWS.
➡Subnets: Neighborhoods within the VPC, each with its own CIDR block (address range). Public subnets allow internet access, while private subnets offer secure internal communication.
➡Resources: Buildings within the subnets. These can be EC2 instances (virtual servers), databases, and more.
➡Security Groups: Traffic lights that control inbound and outbound traffic for your resources.
➡CIDR: (Classless Inter-Domain Routing) is a way to define IP address blocks within your VPC. Think of it as the numbering system for your virtual city's streets.
➡IP Address: The unique identifier for each resource, like a house address.
➡CIDR Block: A range of IP addresses allocated to a subnet, similar to a zip code.
➡CIDR Notation: Combines the IP address with a forward slash and a number (e.g., 10.0.0.0/16). This number indicates how many bits in the IP address define the network portion, determining the number of usable addresses within the block.

✅Benefits of a Well-Designed Network
Understanding VPC diagrams and CIDR empowers you to:
Visualize your network architecture for better management and troubleshooting.
Allocate IP addresses efficiently to avoid waste and ensure scalability.
Implement security best practices by isolating resources in private subnets and controlling traffic flow.

Happy Learning !!
