Serverless PHP @ WDI 2019

#serverless wasn't a hot topic for PHP as none of the major cloud providers is offering native PHP support, but the new AWS Lambda runtime API and layers capabilities give us the ability to build a clean, supportable implementation of PHP on Lambda of our own. In this talk, we’ll take a brief look at the overall workflow and runtime lifecycle, and then I’ll show you how to run PHP on AWS Lambda.

5. Serverless • storage as a service (e.g. Amazon S3), • database as a service (e.g. Amazon Aurora), • message queue as a service (e.g. Amazon SQS), • etc.
6. Serverless replaces the traditional approaches to running applications.
7. Platform options Physical servers Virtual machines Containers Platform Serverless Abstraction Control
8. Why serverless? • We don't manage, update, configure, provision servers or containers, • We don't reserve or scale servers or containers, instead they are scaled automatically and transparently for us, • We don't pay for fixed resources, instead we pay for what we actually use (e.g. execution time).
9. Serverless can provide more scalable, affordable and reliable architectures for less effort.
