Misadventures in monoliths and microservices

My career so far...

The Gordian knot that is Relay Foods

Start with groceries...

  • Thin margins

  • Long tail of products

  • Expiring inventory

Add a bunch of local products...

  • 150 local vendors

  • Across 5 states

  • Tech savviness issues

Promise a tight delivery window

  • Thousands of orders

  • Midnight order cutoff

  • Next day delivery

Differentiate the product

  • Behavioral change

  • Convenience not enough

  • Grocery focused UX

Build an acquisition engine

  • Min user base size

  • Team of canvassers

  • Cowbells...

Behold, the Monolith!

Measured Microservices

Microservices allowed us to:

  • Move quickly & confidently to create biz value

  • Isolate & then mitigate technical risk points

  • Tame complexity by simplifying interfaces

But, microservices were not:

  • without their own issues

  • an excuse to build everything differently

  • a panacea

And for one last story...

Thanks for listening!
