Alexa Skill Kits and Alexa Home also have events that can trigger Lambda functions! Where does this piece of code live, if we aren’t deploying a server? Well, that’s where AWS Lambda comes into play.ĪWS Lambda is the glue that binds many AWS services together, including S3, API Gateway, and DynamoDB. You could most definitely handle this task using the traditional model, but since this code runs based on an event (the file upload), Amazon S3 can fire an event and trigger the execution of code to handle the image resize. Now, say you want to resize the image to a max resolution. The application stores these images in Amazon S3.

For example, let’s say you have an application that allows users to upload a photo for a profile image. While this is still the right way to handle a lot of scenarios, sometimes you just need to run a bit of code to handle some kind of event. In a traditional cloud usage model, you provision servers, deploy code to the server, and manage resource usage and scaling, along with other traditional server activities. Serverless, or Why you don’t need a server!
