In this talk we will talk about the design of our Mesos framework and the scheduler. We will focus on the following aspects of the scheduler – Bin packing algorithms, Scaling in and out of clusters, fault tolerance of processes via reconciliation and processing life cycle events, multi-geography/cross data center redundancy.
This talk will leverage the experience of introducing reactive programming into existing imperative, blocking codebases to demonstrate how it can be done and when it can make sense to do so. Not all benefits of reactive programming can be obtained without a greenfield, fully async architecture, but many can. Subjects to be covered will include the mental shift from imperative to declarative, working with blocking IO such as JDBC and RPC, service composition, debugging and unit testing.
In this talk we’ll be exploring the Reactive Extensions (Rx) library which allows us to treat events as collections. You’ll learn about how Netflix uses Rx on the client and the server, allowing us to build end-to-end reactive systems. We’ll also contrast Rx with Promises, another popular approach to building asynchronous programs in Javascript.
