By &quot;Serverless&quot; we mean the developer does not have to think about servers.  They exist, but Amazon manages them.<p>Instead, the developers deals only with Lambda, an event-driven compute resource.  You upload your code and it runs when triggered, scaling horizontally and massively, out-of-the-box.<p>The workflow rocks because it&#x27;s endpoint&#x2F;function isolation, not just application isolation.  Every piece of logic is in its own container.  Best of all, you only get charged when that code is run (!!!).
