Day 14: AWS Outposts, Wavelength, and Local Zones

A shorter revision today — three AWS edge computing offerings that all bring AWS infrastructure closer to where it's actually needed, each for a different reason.

AWS Outposts

A fully managed service that delivers AWS infrastructure, services, and tools so you can build and run your own applications on-premises as if you were in the cloud. AWS sets up and manages physical server racks within your own premises, letting you start using AWS services on-premises.
Benefits:
  • Low latency access for on-premises systems
  • Local data processing
  • Data residency — keeping data within a specific physical location to satisfy regulatory or compliance requirements
  • Easier migration path from on-premises to the cloud
  • Fully managed by AWS

AWS Wavelength

AWS infrastructure deployments embedded directly within telecommunications providers' data centers, at the edge of their 5G network — enabling ultra-low-latency applications for 5G users. Because application traffic never has to leave the telecom provider's own network to reach it, Wavelength gets high bandwidth and a secure connection back to its parent AWS Region. Note that this specialized placement comes at a cost: EC2, EBS, and data transfer in a Wavelength Zone are priced at a premium compared to a standard AWS Region.
Common use cases: real-time ML inference, connected vehicles, IoT diagnostics, and interactive live video streaming.

AWS Local Zones

An extension of an AWS Region into additional locations, placing select AWS services — compute, storage, database, and more — physically closer to end users to serve latency-sensitive applications.

Coming up: Global Architecture Patterns

A quick preview for next time — four common ways to architect a global application:
  1. Single region, single AZ
  2. Single region, multi-AZ
  3. Multi-region, active-passive
  4. Multi-region, active-active
