Brian Chambers is the Chief Architect at Chick-Fil-A, which is one of the fastest growing fast food restaurants in the US. Brian has been with Chick-Fil-A for 19 years, where the company has gone from $1B to $19B in sales (a nice 19x in 19 years). He’s seen the software architecture evolve from through various technology shifts such as datacenter to cloud, mobile, edge compute, and much more. He joins us today to talk about Chick-Fil-As architecture, how the backend technology maps to real business use cases, and how Architects approach impacting the tech stack especially as waves of technology are occurring. In this episode we talk about managing legacy and cloud systems, when to use new technology vs when to keep something running the same, real edge compute use cases, experimenting with LLMs, and many more areas. For those who are curious as to how a software org works and affects business outcomes in a large enterprise, this is the episode for you.
