Motivation
How to build modern e-commerce applications

7.
more personalization &
targeted Content
= NO frontend caching

Don’t be “Standard”!
Differentiate!
= increased complexity,
more integrations,
multiple channels

How would you love to develop
commerce applications?
Is PHP still the right development
language for this?
??

14.
How would you love to develop commerce applications?
• Performance:
Highly dynamic fast content rendering Individual Personalization and Context aware
rendering
• Clean architecture
• Flexibility in a Microservice architecture:
Flexible to use in microservice oriented individual architectures. Useable with
„headless“ (commerce) services No Build and deploy overhead
• Frontend development flexibility:
Decouple frontend build pipeline from „backend“ logic
• Testability
• Developer Experience:
Effective and Fun to use * low learning curve
• Open Source

15.
Is PHP still the right development language for this?
• Fast Development cycles
• Easy onboarding
• Happy developers
• Focus on writing code. Not tooling.
• Small memory+cpu footprint

16.
Is PHP the right development language for this?
• Webserver included
• Compiled / Type Safe
• Concurrency
• Easy to learn - build to scale
• Supported by Google
• Increasing Interest and Success

17.
Introducing Go
• Founded 2009 at Google
• Motivated by the need to create a language
which is easy to learn, operate and scale
• Rapid grow in the last 3 years

18.
4 out of 6 graduated Cloud Native Computing Foundation
projects using Go

19.
The Go Programming Language
• Type safe
• No type confusion
• No inheritance
• Composition over inheritance
• Implicit interfaces
• If it quacks, it’s can be duck
• No complex exception handling
• You have to deal with your errors
• Easy concurrency
• Go routines and channels

20.
The Go Toolchain
• Build-in Dependency management
• “go modules”
• Minimal Version Selection
• Static and cross-platform compilation
• Linux, Windows, Mac, FreeBSd
• x86, arm, ppc, mips
• No additional tooling needed

21.
Getting started with Go
• Do the interactive tour at
https://tour.golang.org
• Take a look into the standard lib at
https://golang.org/pkg/
• Enjoy development with Flamingo J
