Overview of this book

The surge in connected edge devices has driven organizations to capitalize on the opportunities presented by the massive amounts of data generated by these devices. However, adapting to this landscape demands significant changes in application architectures. This book serves as your guide to edge computing fundamentals, shedding light on the constraints and risks inherent in selecting solutions within this domain. You’ll explore an extensive suite of edge computing services from AWS, gaining insights into when and how to use AWS Outposts, AWS Wavelength, AWS Local Zones, AWS Snow Family, and AWS IoT Greengrass. With detailed use cases, technical requirements, and architectural patterns, you’ll master the practical implementation of these services and see how they work in real life through step-by-step examples, using the AWS CLI and AWS Management Console. To conclude, you’ll delve into essential security and operational considerations to maximize the value delivered by AWS services. By the end of this book, you'll be ready to design powerful edge computing architectures and handle complex edge computing use cases across multiple AWS services.

Routing internet traffic into AWS Local Zones

So far, we’ve covered use cases that involve traffic to and from an existing on-premises data center. This section will review options to address situations where the traffic originates from various locations on the internet.

Application Load Balancer

When an Elastic Load Balancer is set up in an AWS Local Zone, it is done in much the same way as it is in any standard availability zone. First, unlike in a standard region, you only need to assign one subnet. Second, only the layer 7 Application Load Balancer (ALB) variant is available. Layer 4, or network load balancers (NLB), cannot be deployed to an AWS Local Zone.

Amazon Route53 for load balancing

Although ALB addresses layer 7 load-balancing use cases, some low-latency applications that get deployed in AWS Local Zones rely on UDP-based protocols, such as QUIC, WebRTC, and SRT, which can’t be load-balanced by layer 7 load balancers.
