Amazon CloudFront Design Patterns
Using Amazon Route 53
The course is part of this learning path
In this section of the AWS Certified Advanced Networking - Specialty learning path, we introduce you to the various design patterns for content distribution and DNS from an AWS networking perspective that are relevant to the ANS-C01 exam.
- Identify how to leverage Amazon CloudFront for the usage of a content distribution network (CDN)
- Explain how Amazon Route 53 is used to design solutions that meet public, private, and hybrid DNS requirements
- Describe how Route 53 can be used within internet-based architectures to route end users to public-facing applications
The AWS Certified Advanced Networking - Specialty certification has been designed for anyone with experience designing, implementing, and operating complex AWS and hybrid networking architectures. Ideally, you’ll also have some exposure to the nuances of AWS networking, particularly regarding the integration of AWS services and AWS security best practices. Many exam questions will require advanced level knowledge of many AWS services, including AWS networking services. The AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.
Route 53 application recovery controller is a set of capabilities that continuously monitors an application’s ability to recover from failures and controls application recovery across multiple availability zones, regions, and possibly your own data center environments.
You can define a readiness check to monitor AWS resource configurations, capacity, and network routing policies. They can check the configuration of Auto Scaling Groups, Amazon EC2 instances, Amazon EBS volumes, Elastic Load Balancers, RDS instances, and DynamoDB tables among others.
These readiness checks ensure that the recovery environment is scaled and configured to take over when needed. You can check AWS service limits to verify that enough capacity can be deployed. You can also verify that capacity and scaling setups for applications are exactly the same across regions before a failover takes place.
Readiness Checks work with Routing Controls to give you a way to failover an entire application based on custom conditions like application metrics, partial failures, increased error rates, or latency. You can also failover manually. With Routing Controls you can shift traffic for maintenance purposes or during a real failure scenario. You can also apply safety rules to routing controls as a way to prevent a failover to an unprepared replica.
A control panel is a group of routing controls for an application. As mentioned earlier, A routing control is used to turn traffic flow ON or OFF to individual cells in Regions or Availability Zones.
This will permit you to define custom traffic re-direction for your applications during failover or maintenance cycles. Amazon Route 53 Application recovery controller allows you to configure fine-grain failover and verification steps to implement applications requiring very high availability.
