AWS Wavelength is a service that brings AWS compute and storage capabilities to the edge of 5G networks. It allows application traffic to reach application servers without leaving the telecommunications network, minimizing latency and enhancing user experiences. By embedding AWS infrastructure within communications service providers' datacenters, Wavelength enables developers to build and deploy applications that require ultra-low latency.

Edge computing is crucial for 5G networks because it allows applications to run closer to end users, significantly reducing latency. While 5G networks offer high bandwidth and reliability, many applications still rely on servers located far away, which can introduce delays. By processing data at the edge, businesses can improve response times and support new applications in areas like industrial automation, connected vehicles, and augmented reality.

To get started with AWS Wavelength, you need to log into the AWS Management Console and enable Wavelength Zones. Then, create a Virtual Private Cloud (VPC) and subnet in the Wavelength Zone, configure a carrier gateway, and set up a route table to direct traffic to the telecom provider. Finally, you can launch AWS resources, such as Amazon EC2 instances, available in the Wavelength Zone to test connectivity and deploy your application.
