Building Composable Services

Short Form


Composable services and tools have been a hot topic lately. Learn why microservices can help bring your ideas to life faster while being more reliable and resilient. We'll show what frameworks and techniques you can use to build composable services and infrastructure, and help you avoid some of the common pitfalls.


This talk covers the major points of why microservices are becoming an increasingly powerful trend and how to get starting both as a builder and as a consumer of services.

  • Defining composability
  • Availability and scaling
  • Frameworks and databases
  • Service discovery
  • Deployment and operability
  • Immutable applications
  • Cascade failures and visibility

Speaking experience

I've got the last year or so of my talks up at with slides and video when available. I'm a frequent speaker at PyCon as well at local meetups in San Francisco. I gave a shorter version of this talk at the Cloud Identity Summit, you can find the slides at (there is no video that I'm aware of).

        The Internet runs the world; it connects our devices, powers our businesses, and even talks to our thermostats. But how does it all happen? We will follow an adventurous young web browser from the moment a hapless user presses “enter” and witness the trials and tribulations of many packets. Ride alongside the most fearsome syscalls as we learn how the Internet works!
