Building Live Streaming Workflows With AWS Cloud

Live streaming requires consideration of various factors like ingesting, encoding, bandwidth and delivering a hassle-free playback experience. To deliver a smooth live streaming experience with AWS Cloud, you can use several services and tools to provide seamless content to a large audience.

Live streaming workflows have many goals, like capturing durable messages, delivering them in ordered queues for the system to process, aggregating records, keeping up with the pace of new data arriving, and loading results into other downstream systems for further analysis. To tackle these challenges, here are some steps to building live streaming workflows with AWS Cloud.

  • Plan your architecture
    Streaming large quantities of data may present design and architectural challenges for developers. Determine the requirements of your live streaming workflow and choose the AWS services that best suit your needs. AWS offers a range of services for live streaming, including Amazon Elastic Compute Cloud (EC2), Amazon Simple Storage Service (S3), Amazon CloudFront, Amazon Elastic Transcoder, and Amazon Kinesis Video Streams.

  • Set up your encoder
    An encoder is a hardware or software tool that converts video and audio content into a format you can stream online. You can use open-source software encoders like OBS or paid encoders like Wirecast or vMix. Configure your encoder to stream to AWS MediaLive or AWS Elemental Live.

  • Create an AWS MediaLive channel
    AWS MediaLive is a managed service that provides a reliable and scalable platform for live video encoding. Create a channel in AWS MediaLive that will receive the incoming stream from your encoder.

  • Configure AWS MediaPackage
    AWS MediaPackage is a video origination and just-in-time packaging service that lets you securely and reliably deliver streaming content at scale. Configure MediaPackage to receive the output from MediaLive and package it into the appropriate streaming formats.

  • Set up Amazon CloudFront
    Amazon CloudFront is a content delivery network that securely delivers data, videos, applications, and APIs to viewers globally with low latency and high transfer speeds. Configure CloudFront to deliver your live stream to viewers.

  • Scale the workflow
    The workflow needs to be scaled to handle a large number of viewers. AWS Auto Scaling can automatically adjust the resources based on the viewer’s demand.

  • Monitor the workflow
    You must monitor the workflow to ensure it is working as expected. You can use AWS CloudWatch for monitoring. CloudWatch provides metrics and logs that you can use to detect and diagnose issues.

  • Monitor your live stream
    AWS offers a range of tools to help you monitor your live stream, including Amazon CloudWatch and Amazon SNS. Use these tools to monitor the health of your workflow and receive alerts if there are any issues.

  • Analyze the video
    You can analyze the videos you stream to gain insights about the viewers. You can further use these insights and analytics to modify and enhance the experience for users. AWS Elemental MediaTailor is a service you can use to get video analytics. MediaTailor provides metrics such as the number of viewers, the devices used to watch the video, and the geographic location of the viewers.

Building a live streaming workflow with AWS Cloud requires careful planning and configuration. By following the abovementioned steps, you can create a reliable and scalable live streaming workflow that can deliver high-quality video to viewers around the world.
