Download as PPTX, PDF0 likes641 views
The document discusses building cloud-native applications using containers, functions, and managed services, emphasizing Microsoft's mission to empower organizations. It covers developer experience enhancements such as Azure Dev Spaces, CI/CD integration, and application packaging with the CNAB specification, alongside scaling mechanisms using KEDA for Kubernetes workloads. Resources and tools like Azure Monitor and VS Code Live Share are mentioned to facilitate development and collaboration.
KubeCon China 2019 - Building Apps with Containers, Functions and Managed Services
- 1. Building cloud native apps with Containers, Functions and Managed Services Scott Coulton @scottcoulton, Microsoft Patrick Chanezon @chanezon, Microsoft x
- 3. About me
- 4. Agenda • Developer experience • Application packaging • Making your application scale
- 5. Microsoft’s mission “Our mission is to empower every person and every organization on the planet to achieve more.” https://www.microsoft.com/en-us/about
- 6. 3 abstractions • Containers • Functions, triggered by Events • Managed Cloud Services
- 7. Portable Serverless Platforms on top of Kubernetes Fn Nuclio OpenFaaS Galactic Fog OpenWhisk KNative Keda
- 8. Azure Functions is an open- source project Functions runtime and all extensions are fully open source https://github.com/Azure/Azure-Functions
- 9. Dev experience: Azure Dev Spaces Capabilities 1. Use Azure Dev Spaces to iteratively develop, test, and debug microservices targeted for AKS clusters. 2. Azure DevOps has native integration with Helm and helps simplifying continuous integration/continuous delivery (CI/CD) 3. Virtual node—a Virtual Kubelet implementation—allows fast scaling of services for unpredictable traffic. 4. Azure Monitor provides a single pane of glass for monitoring over app telemetry, cluster-to-container level health analytics.

- 15. Azure Dev Spaces + VS Code Liveshare VS Code Live Share: you just need VS Code locally. • Code and all setup on your collaborator’s machine • Code together without setting anything up • Access services on remote machine from localhost • Access terminal on remote machine from VS Code • Works with Azure Dev Spaces on machine sharing the session: double jump to AKS
- 16. VS Code Remote Extension for Containers

- 20. Application packaging CNAB is a specification for building apps • CNAB is not a platform-specific tool • Standard packaging format for multi-component distributed applications • Is agnostic to the cloud or runtime • Uses tools and code you already have https://cnab.io
- 21. Application packaging Microsoft’s implementation of the spec Porter • Porter abstracts the complexity of resources via mixins • Porter uses yaml to define the bundles • Uses containers for the invocation image • Mixin’s can be written for any resources • Supports Kubernetes, Helm, exec and Terraform https://porter.sh
- 24. Scaling your application KEDA allows for fine grained autoscaling (including to/from zero) for event driven Kubernetes workloads. KEDA serves as a Kubernetes Metrics Server and allows users to define autoscaling rules using a dedicated Kubernetes custom resource definition. https://github.com/kedacore/keda
- 25. Scaling your application KEDA can run on both the cloud and the edge, integrates natively with Kubernetes components such as the Horizontal Pod Autoscaler, and has no external dependencies. https://github.com/kedacore/keda
