create VPC

• VPCs → create VPC → VPC and more
• IPv4 + IPv6 → CIDR block → starting IP/block size
• Availability Zones → define number + customize
• Public Subnets → CIDR block, 1 per availability zone
• Private Subnets →CIDR block, ≥ 1 per availability zone
• NAT Gateways → regional, zonal
• VPC Endpoints → access S3 directly from VPC, S3 Gateway

internet gateways

• internet gateways → allows communication between instances in VPC + Internet
• horizontally scaled, redundant, highly available
• no availability risks or bandwidth constraints on network traffic
• internet gateway for lab-vpc

subnets

• subnets → subset of a VPC
• Belongs to a specific VPC
• Exists in a single Availability Zone (while a VPC can span multiple Availability Zones)
