Hey this is Brian and I wrote the article. Personally I don't love "hand waving" so I'd love to answer your question. Its a personal mission now :) Can you help me understand what you mean by "more traditional archi

Hey this is Brian and I wrote the article. Great question. 1) MQTT -- we have a lot of cases where we want to share data between physical or "software" devices in-restaurant, without internet connections. MQTT is our primary chann

This is Brian and I wrote the article, and I am taking this as a massive compliment ;)

You hit on a great point -- Edge infrastructure buffers outbound internet traffic but does not replace the need for a good circuit.

We use K8s in the cloud as well! Our entire control plane for the IOT activity runs there. The rest of the engineering teams have a mix of solutions, but many are moving to K8s as well.

Hey this is Brian -- I wrote the article. I do want to add that Chick-fil-A isnt looking to replace jobs with "robots". We really want to assign our restaurant team members to tasks that add maximum value to customers, which are g

Hey this is Brian -- I wrote the article. It really is an interesting time, especially when you have the scale that Chick-fil-A has. While traditionally a fairly archaic industry (POS registers, ERP at corp, thats about it), the volumes and

Hey, this is Brian and I wrote the article. I have worked at Chick-fil-A for over 17 years. I will volunteer time to take a phone call with anyone that is interested in hearing my first-hand experience with Chick-fil-A and its culture over

Hey this is Brian -- I wrote the article. I have heard the term a lot over the years. I think you could call it that -- the idea being its the "foggy" area between the user and the cloud. The reason we like "micro private clo

Hi Jay -- this is Brian (I wrote the article). There are constant tradeoffs. I am leery to say we are the most sophisticated bare metal setup. I think all of us that are close to the work would love for many parts to be much more sophistica

We should have a Medium post about this soon, but we built a set of tools called Fleet, Atlas, and Vessel. The simple premise is that Fleet generates code for 1..n clusters. By code I just mean yaml files. Atlas is a git repo per cluster th

Most retailers don't have the challenges of scale that we have and I think thats why its weird to see tech innovation in a restaurant. That said, we need it to scale and are grateful to the k8s community for making what we are working

This is Brian -- I wrote the article. We are closed on Sunday but its not dogmatic in nature. We want to make sure that everyone at Chick-fil-A has a great work/life balance. Occasionally we need to do some work on a Sunday but we try

This was a good learning experience for our engineers at our Innovation Center at Georgia Tech in Atlanta. It may bear fruit in the form of a useful solution in the future, though. What is unique to Chick-fil-A is 'volume'. We do

This is Brian -- I wrote the article. For what its worth, we considered trying to run our clusters on an array of cell phones since they would natively support connectivity fallback and pack a real effecient resource punch in a small footpr

This is Brian -- I wrote the article. Super cool use for a NUC! I'm going to follow the links and check out what you did some more.

This is Brian -- I wrote the article (I suspect I will be typing that a lot tonight). We do clusters with 3 nodes per restaurant, so at full scale (when we have rolled out to every restaurant in the chain) that will be ~6000 nodes, and grow
