AWS IoT — Twitter Bridge
This post gives a quick overview one of our applications listed under AWS Serverless Application Repository. Its free, try it!
This serverless application provides a bridge between AWS IoT and Twitter for your devices to send messages to Twitter. The code and details are available at https://github.com/TensorIoT/sar-iot-twitter-bridge
What is AWS Serverless Application Repository?
The AWS Serverless Application Repository is a collection of serverless applications ranging from code samples and components for building web and mobile applications to back-end processing services and complete applications. Each application is packaged with an AWS Serverless Application Model (SAM) template that defines the AWS resources used. The Serverless Application Repository enables you to quickly deploy these code samples, components, and applications for common use cases such as web and mobile back-ends, data processing, chatbots, IoT, and more. There is no charge to use the Serverless Application Repository — you only pay for the AWS resources used in the applications you deploy.
