Content Delivery Services Review Flashcards
What are the Content Delivery services?
CloudFront
Global Accelerator
S3 Transfer Acceleration
CloudFront
A CDN that delivers data and apps globally with low latency
Uses Edge locations
Uses DNS (I think)
static AND dynamic
Security: Shield (DDoS) and AWS WAF (Web App Firewall)
Global Accelerator
Sends users thru the AWS global network to get content rather than public internet
Uses IP addresses (not DNS) = faster
Can route requests to: NLB, ALB, EC2 instance,elastic IP addr
Distance is minimized due to edge locations
How is Global Accelerator different from Cloud Front?
Uses IP instead of DNS routing
Better fault tolerance b/c using IP’s is more instantaneous as IP’s are not cached
CloudFront uses Edge locations to cash content whereas Global Accelerator uses edge locations to find an optimal pathway
When would you choose Global Accelerator?
When you have non-http protocol(VOIP, UDP (gaming/video), MQTT(IoT)
When you require a static IP address
When you need instantaneous failover
S3 Transfer Acceleration
Improves content uploads and downloads to and from S3 buckets
