Going Global with Serverless!

Do you have 50min to spare? Great! I just want 50min of your time to show you how you can deploy a global-scale, multi-region, active-active serverless backend. Oh, and we will do that in less than one hour! You are probably thinking that a few years ago it would have taken six months and a team of ten engineers to do that, and you are right, but serverless has changed the game!

In this session, I walk you through building and deploying a global-scale, multi-region, active-active serverless backend. Demo and hands-on code guaranteed!

Every request is non-failing. Service still responds as expected if some nodes crash. Distributed System In the presence of a network partition, you must choose between consistency and availability!

Embrase eventual consistency … if no new updates are made to a given data item, eventually all accesses to that item will return the last updated value. Availability An eventually consistent system can return any value before it converges!! https://en.wikipedia.org/wiki/Eventual_consistency Distributed System Every request is non-failing.
