AWS Wavelength Specialized2019年〜
Place compute resources at the edge of 5G networks for ultra-low-latency applications
What It Does
AWS Wavelength places AWS compute resources (EC2, ECS, EKS) inside telecom carrier 5G networks. Traffic from mobile devices is processed within the carrier network, achieving single-digit millisecond latency without traversing the internet.
Use Cases
Real-time AR/VR rendering, cloud gaming, real-time data processing for autonomous vehicles, remote control of industrial robots, and real-time live video processing.
Everyday Analogy
Think of an in-store kitchen at a convenience store. Normally, meals are made at a factory (AWS Region) and delivered, but Wavelength puts a kitchen (compute) inside the store (5G base station) to cook (process) orders (requests) on the spot for instant delivery.
What Is Wavelength?
AWS Wavelength is a service for 5G edge computing. A Wavelength Zone is AWS infrastructure installed inside a telecom carrier's data center, used as a subnet in your VPC. Traffic from 5G devices reaches the Wavelength Zone within the carrier network, eliminating internet hops and achieving ultra-low latency.
Wavelength Zones and Architecture
Wavelength Zones are added as subnets to a parent region's VPC. Deploy EC2 instances or ECS tasks to a Wavelength Zone subnet, and traffic from 5G devices reaches them directly. Backend databases and storage are typically placed in the parent region, accessed from Wavelength Zone compute. For technical background on Wavelength Zones and architecture, books on Amazon are a useful resource.
Getting Started
Enable a Wavelength Zone in the EC2 console and create a subnet in your VPC. Deploy an EC2 instance to the Wavelength Zone subnet and assign a carrier IP address. When 5G devices access the carrier IP, they reach the Wavelength Zone instance directly.
Things to Watch Out For
- Wavelength Zones are available only with specific carriers in specific cities. In Japan, KDDI is supported
- Wavelength Zone instance pricing is comparable to standard EC2, but data transfer charges may differ
