Leveraging AWS Global Infrastructure

Question 1

CloudFront

Answer 1

CDN Content Delivery Network
* Improves read performance, content is cached at the edge
* 216 point of presence (edge location)
* DDoS protection integration with Shield, AWS Web App Firewall

Question 2

CloudFront - Origins

Answer 2

• S3 bucket (Origin Access Control OAC)
• Custom Origin (HTTP)

Question 3

CloudFront vs S3 Cross Regions Replication

Answer 3

CloudFront:
* Global Edge network
* Files cached for a TTL (maybe day)
* Great for static content that must be available world wide

S3 Cross Region Replication:
* Must be setup for each region you want replication to happen
* Files updated in near real-time
* Read only
* Great for dynamic content that needs to be available at low latency in few regions
Copy an entire bucket into another region

Question 4

S3 Transfer Acceleration

Answer 4

• Increase transfer speed
• Transfer to an edge location
• Forward the to the S3 bucket in target region

Question 5

Global Accelerator

Answer 5

• Improve global application availability and performance using AWS global network
• Optimize route by 60%
• 2 Anycast IP are created for an app
• Traffic is sent through Edge Locations
• Edge location sends traffic to app

Question 6

Global Accelerator vs. CloudFront

Answer 6

• Both use the AWS global network and edge locations
• Both intergrate with AWS Shield for DDoS protection

CloudFront Content Delivery network
* Improve cahceable content perormance
* Content served at the edge

Global Accelerator
* No Caching
* Proxy packet at eged to apps running in one or more region
* Improve performance for a variety of apps over TCP/UDP
* HTTP use case req static IP
* HTTP use case req deterministic, fast regional failover

Question 7

Outposts

Answer 7

• Hybrid Cloud
• Server racks that offer same AWS infrastructure, APIs, and tools
• AWS will setup and manage “Outposts Racks”
• Extend AWS services to on-prem
• You are responsible for the physical security

Question 8

Benefits of Outposts

Answer 8

• Low latency to on-prem
• Local data processing may never leave
• Data residency
• Easier to migrate to cloud
• Full managed service
• Lots of services work on Outposts

Question 9

WaveLength

Answer 9

• Bring AWS service to the edge of the 5G network
• Low latency through 5G
• Traffic doesn’t leave the communication service providers network.

Question 10

Local Zones

Answer 10

• Places AWS compute, storage, database, and other services closer to the end user to run latency-sensitive applications
• Extend you VPC to more locations - Extension of an AWS Region
• Teir below AZ

Question 11

WaveLength Zones

Answer 11

Infrastructure deployments embedded withi the telecom providers datacentera at the edge ofthe 5G networks
