Challenge Overview

Competition Introduction

Welcome to the AlefEdge & Topcoder Challenge Series!

This challenge series aims to create new opportunities for you to learn and use AlefEdge's 5G Private Edge. Throughout the series, we will be launching several types of challenges (Educational, Topcoder Skill Builder's, and Code Challenges) to help learn and succeed with AlefEdge's platform, SDKs, and APIs. You will get a chance to learn how to create new apps and enhance existing apps that take advantage of the Edge. We also have leaderboards and educational webinars, and of course, great prizes and cool Private Edge & Topcoder T-Shirts.

Alef is the 5G Edge API company. They leverage 5G networks to bring processing power as close to the user as possible, allowing for extremely low latency applications. This decentralization of the internet is an exciting new frontier and there are so many possible applications of Edge technology. In this Skill Builder, we will learn the use case--video streaming using Private Edge Video Enablement API.

Problem Statement

A Media Enterprise named Galaxy is a big enterprise with over 100k employees around the world. These employees either work out of one of the 10k office locations or remotely from their home.

With 100s of business verticals, they have tons of video content to stream to their employees in terms of training, webinars, onboarding, team calls, and whatnot.

With the current state of the internet same around the world. They are wondering whether or not they want to make the move to Private Edge, which can provide 5G type speeds to anyone anywhere in the world.

The Enterprise has hired you to learn the Alef Edge platform, learn how you can use Alef's Private Edge services to host and stream an HD video using the Private Edge 5G Edge APIs and create an application to compare the Video Streaming in Edge and Cloud, with the end goal being to be able to show how fast a video can stream using Edge when compared to the cloud.

In this Skill Builder, we go step by step (Easy, Medium, and Hard) to help you set up, stream a video on Private Edge, and then create a comparison application to compare the stream latency with a video streamed from the cloud.
