5.4In-scope services for networking and content delivery
A roundup of in-scope SOA-C03 services for networking and content delivery—VPC, connectivity, DNS, and delivery.
5.4.1In-scope services for networking and content delivery
For networking and content delivery, focus on the VPC and its components, connectivity, and DNS. VPC and components: Amazon VPC (virtual network), Amazon VPC IP Address Manager (centralized IP planning), Elastic IP addresses (static public IPs), VPC Endpoints (private access to AWS services), VPC peering (direct VPC-to-VPC), and VPC Reachability Analyzer (connectivity diagnostics). Connectivity: AWS Site-to-Site VPN (site-to-site), AWS Client VPN (user devices), AWS Transit Gateway (hub many VPCs), AWS PrivateLink (private access to services), and AWS Global Accelerator (speed up over the AWS network). DNS/delivery: Amazon Route 53 (authoritative DNS) and Amazon Route 53 Resolver DNS Firewall (DNS threat protection).

- Connectivity/DNS: Site-to-Site VPN, Client VPN, Transit Gateway, PrivateLink, Global Accelerator / Route 53, Route 53 Resolver DNS Firewall
