Leveraging AWS Global Infrastructure Flashcards
CloudFront
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
CloudFront - Origins
- S3 bucket (Origin Access Control OAC)
- Custom Origin (HTTP)
CloudFront vs S3 Cross Regions Replication
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
S3 Transfer Acceleration
- Increase transfer speed
- Transfer to an edge location
- Forward the to the S3 bucket in target region
Global Accelerator
- 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
Global Accelerator vs. CloudFront
- 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
Outposts
- 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
Benefits of Outposts
- 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
WaveLength
- Bring AWS service to the edge of the 5G network
- Low latency through 5G
- Traffic doesn’t leave the communication service providers network.
Local Zones
- 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
WaveLength Zones
Infrastructure deployments embedded withi the telecom providers datacentera at the edge ofthe 5G networks
