In recent years, a different way to build applications has arisen called serverless computing. This term is not a good name; I’m reminded of the adage that there are two hard problems in programming: naming things, cache invalidation, and off-by-one errors. Serverless computing as a name implies no servers, but there are servers—you don’t think about them though. A better way to think about it is that the servers and the management of them are abstracted away and the provider manages the allocation of resources, not the application architect. In this article, I’m going to walk through how to use Lambda with PHP to execute a function.
