[AWS SAA-C02 Study Note] Global Acceleration: CloudFront & S3 Acceleration
CloundFront
Content Distribution Network (CDN)
Creates cached copies of your website at various edge locations around the world.
CloudFront support both dynamic and static application.
Intro to CloudFront
Core Componets
Origin, Edge Location and Distribution
Distributions
A distributions is a collection of Edge Locations. You can specific the origin eg. S3, EC2, ELB, Route53
It replicates copies bases on your Price Class
There are 2 types of Distrobutions:
- Web (for websites)
- RTMP (for streaming media)
Lambda@Edge
Protection
By default a Distribution allows everyone to have access
OAI, Signed URLs, Signed Cookies
CloudFront Cheat Sheet
Global Accelerator
Improves the availability and performance of your applications with local and global users.
It provides static IP address that act as a fixed entry point to your application endpoint (ALB or EC2 instances).
set static IP in Route53, and it will return static IP to redirect user to specific edge location

S3 Transfer Acceleration
Amazon S3 Transfer Acceleration can speed up content transfers to and from Amazon S3 by as much as 50-500% for long-distance transfer of larger objects. Customers who have either web or mobile applications with widespread users or applications hosted far away from their S3 bucket can experience long and variable upload and download speeds over the Internet.
！！！加速访问S3和上传到S3的速度！！！
S3 Transfer Acceleration (S3TA) reduces the variability in Internet routing, congestion and speeds that can affect transfers, and logically shortens the distance to S3 for remote applications.
S3TA improves transfer performance by routing traffic through Amazon CloudFront’s globally distributed Edge Locations and over AWS backbone networks, and by using network protocol optimizations. You can turn on S3TA with a few clicks in the S3 console, and test its benefits from your location with a speed comparison tool. With S3TA, you pay only for transfers that are accelerated.
