Functional Architecture (Sydney)

YOW! Nights

Functional Programming has shown the benefits of removing mutation and side-effects, resulting in programs fundamentally simpler and more composable. Nonetheless, many of these programs still rely on applying side-effects to external systems such as databases, file-systems or external services. What happens if we apply these ideas to systems and application architecture, can it make whole systems fundamentally simpler to reason about, build and operate.

Functional approaches to architecture have other key benefits such as being naturally suited to audit and reversion of state to previous versions. They tend to have lower operational risk associated with them. Functional architectures significantly reduce complexity in distributed systems.

This talk looks at the history of systems and applications built with an underlying functional architectures such as journaled file-systems and databases, event sourcing, and content-addressable storage, as well as how these ideas enable.

We’ll see that there is an underlying philosophy of FP that can be brought to most aspects of system design and architecture, even while presenting a mutable face to the world.

Jed Wesley-Smith is a programming philosopher, concerned with how software behaves, scales and composes. He has been a functional programmer for the last 10 years, having discovered FP as a technique to simplify intractable concurrency problems, and then became such an enthusiastic proponent he was nicknamed Captain Immutable at Atlassian. Jed is currently Director of Engineering at Simple Machines, is a YOW! Evangelist, as well as a co-organiser of the FP-Syd and ScalaSyd user-groups.
