Pulumi makes it easy to build cloud applications that use a combination of containers, lambdas, and connected data services and infrastructure: Colada apps.
An example of a Colada app is extracting a thumbnail from a video. A serverless function can only run for 5 minutes, so we'll run a container in AWS Fargate to do the video processing.
In this app, a Lambda function is triggered whenever a new video is uploaded to S3. This function launches a task in Fargate that uses FFmpeg to extract a video thumbnail. A second Lambda function is triggered when a new thumbnail has been created.
