The Challenges of building Cloud Native Platforms
1 like716 views
This document discusses the challenges of building cloud native platforms on top of Kubernetes and demonstrates tools that can help, including Crossplane, VCluster, and Knative Serving. It notes that Kubernetes alone is not enough and platforms are needed to reduce complexity for development teams. The demo shows how Crossplane can provision resources, VCluster can provide isolated clusters without cost, and Knative Serving can automate scaling. Together these tools allow platforms to self-service provision environments and deploy tools for teams in a standardized way.

- 6. Agenda • The need for building platforms on top of Kubernetes • The challenges of building platforms • DEMO 🤓
- 7. The need for building platforms • Kubernetes is not enough • One Kubernetes cluster is not enough • Organisations and Teams have di ff erent requirements, di ff erent needs • Avoiding App Dev teams cognitive overload
- 8. What is a platform and why we need one? • Platform == Collection of services (APIs) focused on automating and providing a self-service approach to consume complex infrastructure + tools • By building platforms we: • Reduce the cognitive load on teams • Provide a self-service API to abstract complexity • Improve your software delivery practices by treating the platform as a product
- 9. Platform team An organisational change Platform Kubernetes Infrastructure App App App App Dev Teams Platform Team Infrastructure Team https://teamtopologies.com/ APIs
- 10. Challenges • Multi Cluster & Multi Cloud setups are complex • Installing & maintaining platform-wide tools • CNCF landscape 🤯
- 11. Let’s build a platform • Expectations • App Dev teams can create environments to do their work • Without needing to know all the details about how tools are installed, cluster created and things con fi gured • They need isolation from di ff erent teams • Platform team de fi nes which tools are going to be used and how they will be con fi gured • Platform decisions are encapsulated behind a clearly de fi ned API
- 12. Tools that we will be using • Crossplane • Crossplane Helm Provider • VCluster • Knative Serving • Knative Functions
- 13. Crossplane Provisioning Cloud Resources • Reuses the Kubernetes Resource model to provision cloud resources • Compose and con fi gure resources together • Support for multi-cloud providers
- 14. With Crossplane Creating cloud resources is easy Platform Cluster GKE Cluster EKS Cluster AKS Cluster GCP Credentials Azure Credentials AWS Credentials S3 Bucket Cloud SQL Azure Function cluster.yaml … … …
- 15. <<My Thing>> With Crossplane Compose cloud resources Platform Cluster GKE Cluster GCP Credentials Cloud SQL mything.yaml Blob Storage Cloud Function
- 16. Crossplane Is awesome but.. • Creating Cloud Resources cost $$$ • You need to manage Crossplane • You probably need a separate cluster for running Crossplane
- 17. VCluster Isolated Clusters inside a Cluster • Isolated API Server per namespace and automatic sync of resources • API Server isolation where a namespace is not enough • It is simple as installing a Helm Chart Kubernetes VCluster A API Server API Server VCluster B API Server
- 18. Namespace vs VCluster vs Cluster Isolation without the $$$
- 19. Development Environment Example Platform API Can I have a Dev Environment? Development Environment Sure you can, let me create one for you …
- 20. Staging Environment Example Crossplane + Cloud Provider Platform Cluster Can I have a Staging Environment? Staging Environment Sure you can, let me create one for you …
- 21. Development Environment Example Crossplane + VCluster Platform Cluster Can I have a Dev Environment? Development Environment Sure you can, let me create one for you … https://salaboy.com/2022/08/03/building-platforms-on-top-of-kubernetes-vcluster-and-crossplane/
- 22. Our platform can create clusters! 🥳 🥳 🥳 🥳 🥳 🥳 🥳
- 23. Quick recap • We can create clusters using a declarative approach • We can compose cloud resources • We can use VCluster to avoid paying for full-blown Kubernetes clusters • But… this is just the beginning
- 24. What about Tools? 🛠🪚
- 25. Knative Serving • Knative Serving provides • Scaling up and down (to zero) based on tra ffi c • Advanced tra ffi c management • Simpli fi ed developer experience (less yaml) • You need to install Knative Serving on your clusters
- 26. Multiple Environments Using resources Platform Cluster Development Environment B Development Environment A Staging Environment Development Environment C Development Environments Production Environment
- 27. Development Environments Welcome VCluster Plugins Using resources wisely Platform Cluster Development Environment B Development Environment A Development Environment C
- 28. Crossplane + VCluster + Knative Serving DEMO TIME
- 29. Demo recap Developer Experience is important Platform Cluster Development Environment Let’s create and deploy a function to our freshly created Development Environment! Function
- 30. Demo recap Deploying to production Platform Cluster Development Environment Let’s create and deploy a function to our freshly created Development Environment! Function GIT Production Cluster Function
