*Use cases of AWS Lambda

  1. Another popular use case for AWS Lambda is event-driven data processing. Whenever new data is available, an event is generated. The event triggers the data processing needed to extract or transform the data. Figure 7.23 shows an example. 1 The load balancer collects access logs and uploads them to an object store periodically. 2 Whenever an object is created or modified, the object store triggers a Lambda function automatically. 3 The Lambda function downloads the file including the access logs from the object store, and sends the data to an Elasticsearch database to be available for analytics.
