The internal developer platform: Scaffolding for cloud-native development @ We Are Developers Berlin 2023

Abstract

Learn how Backstage and golden paths supply a complete foundation for cloud-native development with a microservices-based architecture app. This end-to-end developer experience demo will focus on the Red Hat OpenShift Container Platform.

We'll show how Backstage will support you with immediate signposts to components, resources, and relevant documentation. Your team can deploy the right tools and components to get to work immediately.

Discover how Backstage tools help you mount your team's scaffolding and apply best practices atop. View and change source code in Red Hat OpenShift Dev Spaces, a web-based integrated development environment (IDE) built on Visual Studio Code (VSC).

Automate the build-test-deploy cycle using GitOps and build-test pipeline modules as you iterate your application with new features and fixes.

1. Scaffolding for Cloud-Native Development The Internal Developer Platform Hans-Peter Grahsl Developer Advocate @ Red Hat 1 @hpgrahsl
2. This shouldn’t be too hard… 2 Let’s build an application!
3. Let’s build an application! 3 We’ll just grab our editor and write the code… period.
4. Let’s build an application! 4 We’ll just grab our editor and write the code. Seriously dude?
5. 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 …
6. 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 🙈.
7. I’ll just quickly grab this and only add one more little thing… 7 https://twitter.com/dastbe/status/1303858170155081728
8. CNCF Landscape Evolution “Explosion” 8 https://datamattsson.tumblr.com/post/634050924099272704/remember-2017
9. 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
10. Is “shifting left” (still) a good thing going forward? 10 <<
11. 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
12. Probably better to start “shifting down” … 12 But how ? <<
13. Internal Developer Platforms 13
14. 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
15. Golden Paths Golden Path 15 pre-architected and supported approach to building and deploying a particular piece of software
16. 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. 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
18. 18 Introducing…
19. What is Red Hat Developer Hub? 19 An enterprise-grade, open developer platform for building developer portals, containing a supported and opinionated framework.
