Cloud native is about how an application is built and deployed, not where it resides.

A History Lesson Late 90’s Enterprise Application (EAI) Services and Models Addressed integration and transactional challenges primarily by using message oriented middleware. Mostly proprietary systems needing a proliferation of custom interfaces. Mid 00’s Service Oriented Architectures Based on open protocols like SOAP and WSDL making integration and adoption easier. Usually deployed on an Enterprise ESB which is hard to manage and scale. Early 10’s API Platforms and API Management REST and JSON become the defacto standard for consuming backend data. Mobile apps become major consumers of backend data. New Open protocols like OAuth become available further simplifying API development . 2015 and beyond Cloud Native and Microservice Architecture Applications are composed of small, independently deployable processes communicating with each other using language-agnostic APIs and protocols.

Cloud Native Building Blocks 7 Microservices Automated DevOps Containers Results in a lightweight, modular, highly automated approach

Key tenets of a cloud native application 1. Packaged as light weight containers 2. Developed with best-of-breed languages and frameworks 3. Designed as loosely coupled microservices 4. Centered around APIs for interaction and collaboration 5. Architected with a clean separation of stateless and stateful services 6. Isolated from server and operating system dependencies 7. Deployed on self-service, elastic, cloud infrastructure 8. Managed through agile DevOps processes 9. Automated capabilities 10. Defined, policy-driven resource allocation https://thenewstack.io/10-key-attributes-of-cloud-native-applications/ https://cloudnative101.dev/concepts/cloud-native/

Lab

• Open source governed by Continuous Delivery Foundation • Contributors from IBM, Google, Red Hat, and more • Cloud-native built upon Kubernetes • Pipelines, Tasks, PipelineRuns, etc. are CRDs • Formerly known as “Knative Build” and “Knative build- pipelines” • Parallel workflows, triggers, every step isolated in a container, etc. • Pipeline-as-code (yaml) • Pipeline portability across clouds and vendors • Trigger on Git commits, pull (merge) requests, webhook, manually, or specific times. • Fostering ecosystem of common pipelines and tasks, e.g. tool integrations, compliance process https://tekton.dev Tekton 22 IBM Cloud / © 2020 IBM Corporation

Tekton Concept: Step • The smallest building block • Specify images, commands, arguments • Is a container steps: - name: echo image: ubuntu command: - echo args: - "hello world"

Tekton CRD: Task • New CRD • Sequence of Steps • Run in sequential order • Reusable • Perform a specific task • Runs on the same k8s node apiVersion: tekton.dev/v1alpha1 kind: Task metadata: name: echo-hello-world spec: steps: - name: echo image: ubuntu command: - echo args: - "hello world"

Tekton CRD: Pipeline • Expresses Tasks • Sequentially • Concurrently • Links input and output • Execute Tasks on different nodes apiVersion: tekton.dev/v1alpha1 kind: Pipeline metadata: name: tutorial-pipeline spec: - name: build-app taskRef: name: build-push resources: outputs: - name: image resource: my-image - name: deploy-app taskRef: name: deploy-kubectl resources: inputs: - name: image resource: my-image from: - build-app

Tekton Runtime CRDs • Instances of Pipelines and Tasks: • PipelineRun • TaskRun • Runtime info such as registry information and git repo apiVersion: tekton.dev/v1alpha1 kind: PipelineRun metadata: name: tutorial-pipeline-run-1 spec: serviceAccountName: tutorial-service pipelineRef: name: tutorial-pipeline resources: - name: source-repo resourceRef: name: skaffold-git - name: web-image resourceRef: name: skaffold-image-leeroy-web
