Scaffolding for Cloud-Native Development The Internal Developer Platform Hans-Peter Grahsl Developer Advocate @ Red Hat 1 @hpgrahsl

This shouldn’t be too hard… 2 Let’s build an application!

Let’s build an application! 3 We’ll just grab our editor and write the code… period.

Let’s build an application! 4 We’ll just grab our editor and write the code. Seriously dude?

Yeah… We’ll just need … 5 … to create container images, and a container registry to share them, and a place to run all our containers …

Yeah… We’ll just need … 6 … oh, and a lot(!) of YAML 😱, and some CI/CD to build & deploy it, and a repository to store our code … and all our YAML 🙈.

I’ll just quickly grab this and only add one more little thing… 7 https://twitter.com/dastbe/status/1303858170155081728

What’s the problem? Lack of organization can lead to a lengthy and inconsistent onboarding experience - it’s costly and also frustrating for developers! 9

Is “shifting left” (still) a good thing going forward? 10 <<

We’re simply asking too much of developers … 11 “Today’s developers are asked to know web frameworks, architecture patterns, testing strategies, build systems, multiple types of databases, caches, automation tools, container orchestrators, L4-L7 networking concepts, SaaS APIs, monitoring systems, numerous public clouds, and oh, maybe a little machine learning.” https://cloud.google.com/blog/products/application-development/richard-seroter-on-shifting-down-vs-shifting-left — Richard Seroter

Probably better to start “shifting down” … 12 But how ? <<

Internal Developer Platforms 13

14 What is an Internal Developer Platform (IDP)? Internal Developer Platform ▸ built by a platform team to enable developer self-service ▸ provides developers with guided and supported paths to success ▸ typically composed of different technologies and tools

Golden Paths Golden Path 15 pre-architected and supported approach to building and deploying a particular piece of software

Golden Paths 16 What does a Golden Path contain? ▸ a templated repository hosting the initial code base ▸ a set of manifests for deploying applications and provisioning resources ▸ pre-configured but customizable CI/CD pipeline ▸ baked in observability with reasonable default settings

17 Why use an Internal Developer Platform (IDP)? Internal Developer Platform Operations ● Accounts for governance and standardization ● Handles logistics for automating deployment tasks Project Managers (PM) ● Project management tool consistency & organization ● Improved planning by defining a clear set of steps & dependencies Security ● Ensuring best practices are followed (vulnerability scanning, pen testing, etc) ● Visibility into security posture of applications Quality Assurance (QA) ● Automated testing integrated into Golden Path ● Visibility into testing process to help identify problems ▸ makes different & complex tech stacks approachable in a consistent way ▸ allows for faster adoption of new technologies by removing friction ▸ not only for developers → beneficial also to Ops, Security, PM & QA
