DNS & Content Delivery on AWS
The course is part of this learning path
This section of the Solution Architect Associate learning path introduces you to the core networking concepts and services relevant to the SAA-C03 exam. We start with an introduction to the AWS Virtual Private Network (VPC) and networking services. We then understand the options available and learn how to select and apply AWS networking services to meet specific design scenarios relevant to the Solution Architect Associate exam.
- Get a foundational understanding of VPCs, their security, and connectivity
- Understand the basics of networking including Elastic IP addresses, Elastic Network Interfaces, networking with EC2, VPC endpoints, and AWS Global Accelerator
- Learn about the DNS and content delivery services Amazon Route 53 and Amazon CloudFront
Traffic flow simplifies the process of creating and maintaining records in large and complex configurations. This is useful when you have a group of resources that perform the same operation, such as a fleet of web servers for the same domain.
The traffic flow visual editor lets you create complex sets of records and see the relationships among them. You can combine multiple routing policies and health checks in a single configuration. Each configuration is called a traffic policy and it’s automatically versioned so you don’t have to start all over again when your configuration changes. Old versions of traffic policies continue to be available until you delete them.
A traffic policy can define hundreds of records. Traffic flow creates all those records automatically when you create a policy record. You create policy records to associate traffic policies with a domain or subdomain name records. The traffic policy record appears in the list of records for the hosted zone. You can use the same traffic policy to create records in multiple public-hosted zones. This is useful when you’re using the same hosts for multiple domains.
Please note that the Geo-proximity routing policy is available only if you use traffic flow.
