19. PHP • Most apps primarily were LAMP stack • Modern PHP frameworks ◦ Later started adopting Laravel • Virtual Machine ◦ Deploys to VMs, apache vhosts
20. 2016 • Build ◦ Docker images • Deploy ◦ Kubernetes • Microservices ◦ Decompose based on capability
21. How Bold uses Go • Labs project (~2016) ◦ Wifi marketing ◦ Firmware, compile to arch (32 bit MIPS)
22. How Bold uses Go • Command line interfaces ◦ CLI to help automate Rackspace Cloud Infrastructure ◦ Dev cli to bootstrap dev envs https://github.com/spf13/cobra
23. How Bold uses Go • Async Processing ◦ Jobs and queues ◦ Issues w/ Laravel jobs and RabbitMQ ◦ Performance (slow to trigger, process) • PHP process model ◦ req / response ◦ Not suited for long running processes
24. Go + PHP Web server backend Worker Database queue i.e. process webhook
25. How Bold uses Go • APIs ◦ Move to more API centric model & micro services ◦ Less of a benefit to using a PHP + Laravel for APIs ◦ Newer services tend to be written in Go ◦ Move to gRPC for our service definitions
26. How Bold uses Go api gateway API 1 API 2 API 3 API 4 API (n) https gRPC Database
27. How Bold uses Go • Unit testing ◦ Ginkgo: https://github.com/onsi/ginkgo • Database / SQL ◦ Not using an ORM (like Active Record) ◦ Use squirrel for SQL building • Shopify Go Client (official) ◦ https://github.com/bold-commerce/go-shopify
28. Wrap Up
29. Summary • Pros: ◦ Simple, relatively easy to learn ◦ Standard library vs. frameworks ◦ Concurrency ◦ Low footprint ▪ Memory, go routines, docker image size • Cons ◦ general purpose vs. less framework-y (ala Rails)
31. Resources • A Tour of Go ◦ https://tour.golang.org • Go by Example ◦ https://gobyexample.com • Go Playground ◦ https://play.golang.org • Boldly Going (our technical blog) ◦ https://medium.com/boldly-going
