Unit 1 Curriculum Overview: Advanced AWS Network Design

This curriculum provides a comprehensive path to mastering Domain 1 of the AWS Certified Advanced Networking – Specialty (ANS-C01). It focuses on the architectural principles required to design scalable, secure, and high-performance network infrastructures on AWS.

Prerequisites

Before beginning this unit, candidates should possess the following foundational knowledge:

• AWS Core Services: Proficiency equivalent to the AWS Certified Solutions Architect – Associate level, specifically regarding VPCs, Subnets, and Security Groups.
• Networking Fundamentals: Deep understanding of the OSI model, TCP/IP, and CIDR notation.
• Routing Protocols: Basic knowledge of static vs. dynamic routing and the purpose of BGP (Border Gateway Protocol).
• Security Basics: Understanding of SSL/TLS encryption and Public Key Infrastructure (PKI).

Learning Objectives per Module

Module 1.1: Edge Network Services

• Design global architectures using CloudFront to optimize content delivery through edge locations and regional edge caches.
• Configure AWS Global Accelerator to leverage the AWS global network for improved latency using Anycast IP addresses.
• Implement edge security using SSL/TLS termination and AWS WAF integration.

Module 1.2: DNS & Load Balancing

• Design hybrid DNS solutions that resolve queries across public, private, and on-premises environments.
• Select the appropriate Elastic Load Balancer (ELB): Application (L7), Network (L4), or Gateway (Next-Gen Firewall integration).

Module 1.3: Connectivity Strategies

• Architect redundant hybrid connections using AWS Direct Connect and Site-to-Site VPN.
• Manipulate BGP Attributes (e.g., AS Path, Local Preference) to influence inbound and outbound traffic patterns for load sharing or active/passive failover.
• Design multi-account and multi-region connectivity patterns using Transit Gateway and VPC Peering.

Success Metrics

To ensure mastery of Unit 1, learners must demonstrate:

1. Architectural Selection: The ability to choose between CloudFront and Global Accelerator based on the protocol (HTTP vs. TCP/UDP).
2. Traffic Engineering: Successful configuration of BGP attributes to prefer a high-bandwidth Direct Connect path over a backup VPN.
3. Security Compliance: Designing a zero-trust edge architecture using Lambda@Edge for authentication and WAF for threat mitigation.
4. Scaling Proficiency: Configuring Auto-Scaling groups behind an ALB with health check integration that prevents "black-holing" traffic.

Real-World Application

[!IMPORTANT] Why this matters: In a professional setting, efficient Network Design directly impacts a company's bottom line through cost optimization and user retention.

• FinTech: Using Global Accelerator to reduce latency for high-frequency trading platforms or global banking apps.
• Media/Streaming: Leveraging CloudFront invalidations and edge caching to deliver 4K video content globally with minimal buffering.
• Enterprise IT: Building a "Global Transit Hub" using Transit Gateway to connect hundreds of VPCs across multiple AWS accounts, replacing complex mesh peering.
