Talk: Escape the lock-in: How Our Functions Run on AWS, Azure and Google Cloud

Can your code be reused when moving from one cloud vendor to another? Yes! We’ve faced a related problem: The open-source projects we provide to our customers must run on AWS, Azure, and Google Cloud at the same time.


In this session we will live demo two functions: one reacting to HTTP requests and another for an event from a Message Queue (AWS SNS, Azure Service Bus, GC Pub/Sub). Next, we’ll show how the same code implementing our business logic runs on Lambda, Azure Functions and GC Functions with a small adapter.


Based on this, we’ll look at what you can easily do today to avoid vendor lock-in, but also discuss when it’s difficult to do so.
