Serverless PHP @ PHPCon Poland 2019

#serverless nie był do tej pory gorącym tematem w świecie PHP, ponieważ żaden z dostawców usług chmurowych nie wspiera natywnie PHP w środowisku tego typu. Pod koniec zeszłego roku AWS udostępniło dwie nowe usługi (Lambda Runtime API oraz Lambda Layers), które pozwalają na samodzielne dodanie PHP do środowiska typu #serveless. Podczas prezentacji omówię poszczególne elementy takiej architektury oraz pokażę kod PHP działąjacy na AWS Lambda.

14. Why serverless?
15. Why serverless? • We don't manage, update, configure, provision servers or containers,
16. 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,
17. 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).
18. Serverless can provide more scalable, affordable and reliable architectures for less effort.
