With API Gateway and Lambda, you’re forced to use relatively short timeouts on the server-side: API Gateway. Users can also invoke functions on-demand, using, for example, a mobile app with the AWS SDK to execute an exposed AWS Lambda API. js, Python or Java. The steps will be explained below. The Lambda Function itself includes source code and runtime configuration. TimerCheck. This code downloads the price information from AWS using the AWS Price List API, filters and sorts the data, then uploads the interesting parts (for this example, only on-demand Linux pricing for each region) to the S3 bucket. With AWS Lambda, computing infrastructure is entirely managed by AWS, meaning developers can write code and immediately upload and run it in the cloud, without launching EC2 instances or any type of computing infrastructure. They are being caused by Slack. Not only SQS is a valid trigger nowadays but it's also better to start the Fargate service only and if it's necessary.
