How to Build the Greatest and Best Pipeline in the World - JAX 2023

The Heart of any well-performing team is it‘s own hand-crafted Engineering process. But a heart would be useless without veins that pass along the blood and can take the pressure that the heart builds. In a similar manner a team needs it’s own hand-crafted pipeline. Most teams today have one but only few teams have a pipeline that can take the pressure and not collapse. This talk is how to build this Greatest and Best Pipeline in the world.

To be realistic though, it‘s more of a tribute to the greatest and best pipeline in the world. Not because we couldn’t remember but because we want to show you how you can build your greatest and best pipeline.

Since your process is different from ours we‘ll show you how to hand-craft your pipeline and not prescripe a solution that won't fit.

The examples will cover building, bundling, testing and securing your deployment artifact. They'll be written in Gitlab-Ci format and deploy to Kubernetes, but you can apply the same principles and patterns to any other pipeline and any other environment.

5. Slides by richargh.de and 5 Why How Who
6. Slides by richargh.de and Big bang releases only lead to big bangs 6
7. Slides by richargh.de and (1 We are more often wrong then right about which features produce value 7 1 https://blackswanfarming.com/how-to-tilt-the-innovation-playing-field 1
8. Slides by richargh.de and (2) Big Releases are High-Risk • The effect of sth big is extremely hard to anticipate, way too many variables • If something goes wrong • You have a huge change to sift through • It’s hard to roll-back 8 2
9. Slides by richargh.de and (2) Big Releases are Expensive 9 3 Cost Batch Size Transaction Cost Holding Cost Total Cost Optimal Batch Size What if we could bring the transaction costs way down? 1 https://hbr.org/2012/05/six-myths-of-product-development

20. Slides by richargh.de and 20 Why How Who Prepare Build Optimize
21. Slides by richargh.de and Make it economic to work in small batches • Good pipelines require good architecture • Uncouple your code • Test on multiple levels • Version everything à EverythingAsCode • Convince your Stakeholders 21
22. Slides by richargh.de and Uncouple your Code High Coupling Low Cohesion Low Coupling High Cohesion 22 Dependency Unknown Source
23. Slides by richargh.de and Write and test focused modules • Systems consist of modules • Modules • Provide a simple api • Hide their internals • Are deep, not shallow1 • Call api of other modules 23 1 A Philosophy of Software Design Dependency
24. Slides by richargh.de and Make it clear what your module does, what the api is and what is internal src/features/core/ ├── renting/ │ ├── internal/ │ │ ├── a.service.ts │ │ ├── a.repository.ts │ │ └── ... │ ├── exposed-types/ │ │ ├── a.type.ts │ │ └── ... │ ├── a.renting.facade.ts │ └── another.renting.facade.ts ├── paying/ │ ├── internal/ │ ├── exposed-types/ │ └── a.paying.facade.ts src/commons/── paying/ │ ├── internal/ 24 ✘ The focus of a module is declared via verb Internals are declared via your convention Facade and types define the module api Great place to test • Test is structure-insensitive • If the test is simple to write, the api is also simple Great place to test • If it’s a leaf • If the test is simple to write, the code simple Bad place to test • If it composes multiple other internals • The test now locks down your internal structure

66. Slides by richargh.de and A Set of Unit Testing Rules A test is not a unit test if: • It talks to a database • It communicates across the network • It touches the file system • It can't run at the same time as any of your other unit tests • You have to do special things to your environment (such as editing config files) to run it. Tests that do these things aren't bad. Often they are worth writing, and they can be written in a unit test harness. However, it is important to be able to separate them from true unit tests so that we can keep a set of tests that we can run fast whenever we make our changes. 66 1 A Set of Unit Testing Rules https://www.artima.com/weblogs/viewpost.jsp?thread=126923
