What It Does

Amazon Chime SDK is a development kit for embedding real-time voice calls, video conferencing, screen sharing, and messaging into your own applications. It provides a high-quality communication infrastructure powered by AWS's global network, accessible through APIs and SDKs. It offers enterprise-grade communication features as a fully managed service, including WebRTC-based real-time communication, PSTN (public switched telephone network) connectivity, SIP trunking, and media pipelines for recording and transcription.

Use Cases

Chime SDK is used for embedding video consultation features in telehealth platforms, adding live class capabilities to online education services, integrating voice and video calling into customer support apps, implementing real-time messaging in internal collaboration tools, and building call center systems with PSTN connectivity and call recording.

Everyday Analogy

Think of it like LEGO blocks. Building a video calling system from scratch is like constructing a house from the foundation up. Chime SDK provides communication building blocks for calls, video, and chat, so you just pick the blocks you need and assemble them to quickly build your own communication app.

What Is Chime SDK?

Amazon Chime SDK is a developer-focused service that exposes the communication infrastructure of Amazon Chime. While Amazon Chime itself is a complete video conferencing service, Chime SDK provides its communication engine as building blocks that developers can freely integrate into their own applications. SDKs are available for JavaScript, iOS, and Android, enabling use from web browsers and mobile apps.

Voice, Video, and Messaging

Chime SDK provides three core communication features. The meeting feature supports video conferences with up to 250 participants, including screen sharing and content sharing. The messaging feature enables real-time text chat, file sharing, and push notifications. The PSTN Audio feature allows connectivity with the public telephone network, including phone number provisioning, call routing, and IVR (interactive voice response) setup. For design patterns and operational practices for voice, video, and messaging, you can also find detailed explanations in reference books (Amazon).

Media Pipelines and AI Integration

With Chime SDK's media pipeline feature, you can incorporate advanced processing such as meeting recording, audio transcription, and real-time sentiment analysis. Real-time transcription with Amazon Transcribe, sentiment analysis of speech content with Amazon Comprehend, and automatic meeting recording to S3 are all possible. This lets you build intelligent communication platforms that go beyond simple communication tools.

Things to Watch Out For

  • Pricing is usage-based depending on the number of video conference participants and media pipeline usage, so perform cost estimates in advance for large-scale deployments.
  • PSTN features have restrictions on available regions and phone number types, so check supported countries and regions beforehand.
