In this section, you'll explore AWS network connectivity and hybrid networking solutions that enable secure communication between VPCs, AWS services, and on-premises environments. You'll begin by comparing NAT gateways and NAT instances and understanding how they provide outbound internet connectivity for resources in private subnets. As you progress, you'll learn about VPC peering, VPC endpoints, and AWS PrivateLink, including how they enable private communication between networks and AWS services. You'll also explore AWS Transit Gateway and how it simplifies connectivity across multiple VPCs and networks. The section further introduces AWS VPN and AWS Direct Connect, helping you understand how to establish secure and reliable connectivity between on-premises infrastructure and AWS environments. By the end of this section, you'll have a solid understanding of AWS network connectivity and hybrid networking solutions, enabling you to select appropriate connectivity options based on security, scalability, and network requirements.

In this section, you'll explore global application delivery and traffic optimization services in AWS. You'll begin by learning about AWS API Gateway and AWS Global Accelerator and understanding how they support application connectivity, routing, and performance. As you progress, you'll explore Amazon CloudFront and its global edge locations, including how content delivery networks improve application performance by delivering content closer to users. You'll also gain practical insights into creating CloudFront distributions, configuring caching and geographic restrictions, and using Origin Access Control (OAC) to secure access to Amazon S3 origins. The section further introduces S3 presigned URLs and CloudFront signed URLs, helping you understand how to provide controlled access to private content. You'll also explore Time to Live (TTL) settings and CloudFront pricing to understand their impact on caching behavior and content delivery costs. By the end of this section, you'll have a solid understanding of global traffic management and content delivery in AWS, enabling you to improve application performance, security, and delivery efficiency.

In this section, you'll explore Amazon Route 53 and its role in Domain Name System (DNS) management and intelligent traffic routing. You'll begin by learning how to register a domain, create DNS records, and connect domain names to AWS resources. As you progress, you'll explore Route 53 routing policies, including simple, weighted, latency-based, failover, and multivalue answer routing. Through practical demonstrations, you'll understand how these policies direct user traffic based on application requirements, performance, and availability. The section further covers integrating third-party domains with Route 53 and the steps involved in managing and cleaning up DNS configurations. By the end of this section, you'll have a solid understanding of Route 53 and DNS routing policies, enabling you to manage domain configurations and direct application traffic effectively.
