How to set up a Load Balancer on AWS

In this tutorial we are going to embark on a journey of setting up a Load Balancer on AWS.

Load Balancer does exactly what it says it does — it balances the load between your Callaba instances to ensure that none of the servers get overloaded with requests and all of your viewers can receive the video content without any issues. For production ingest and monitoring, see continuous streaming. For playback integration and analytics, use video api. Recommended product path: Ingest & route, Player & embed. For this workflow, Player & embed is the most direct fit., and scaling guide. For this workflow, Paywall & access is the most direct fit. For implementation details, continue with How to set up CloudFront on AWS and optimize data transfer and Creating a Test App to manage Callaba Engine on AWS using a RESTful API. Before full production rollout, run a Test and QA pass with Generate test videos and streaming quality check and video preview.

This tutorial will take 10–15 minutes to complete.

You’ll see your Load Balancer being created.

14. In EC2 Console, navigate to the Target Groups
