Kubernetes VS. App Service: When the orchestrator challenges the platform
Download as PPTX, PDF1 like350 views
The document discusses Kubernetes and how it can be used with Azure to deploy and manage containerized applications. It provides an overview of Kubernetes and how it works, then discusses how Azure services like Azure Kubernetes Service (AKS) can simplify tasks like provisioning clusters, upgrading, scaling, and providing additional capabilities for development, deployment, security and management without having to manage the underlying infrastructure.

- 11. How Kubernetes works 1. Kubernetes users communicate with API server and apply desired state 2. Master nodes actively enforce desired state on worker nodes 3. Worker nodes support communication between containers 4. Worker nodes support communication from the Internet Kubernetes control API server replication, namespace, serviceaccounts, etc. -controller- manager -scheduler etcd Master node Worker node kubelet kube-proxy Docker Pod Pod Containers Containers Worker node kubelet kube-proxy Docker Pod Pod Containers Containers Internet Internet
- 12. Kubernetes on its own is not enough Save time from infrastructure management and roll out updates faster without compromising security Unlock the agility for containerized applications using: • Infrastructure automation that simplifies provisioning, patching, and upgrading • Tools for containerized app development and CI/CD workflows • Services that support security, governance, and identity and access management IDE container support Registry supporting Helm CI/CD Monitoring Microservice debugging NetworkingVirtual machines Security Governance Identity Source code repository<> Kubernetes Storage Data Infrastructure automation
- 14. Manage Kubernetes with ease • Automated provisioning, upgrades, patches • High reliability, availability • Easy, secure cluster scaling • Self-healing • API server monitoring • At no charge (you don’t pay the managed control plane) Infrastructure automation API server Controller ManagerScheduler etcd Store Cloud Controller Self-managed master node(s) Customer VMs App/ workload definitionUser Docker Pods Docker Pods Docker Pods Docker Pods Docker Pods Schedule pods over private tunnel Kubernetes API endpoint Azure managed control plane

Azure makes Kubernetes easy Accelerate containerized application development Task The Old Way With Azure Build a containerized app and deploy to Kubernetes Build the app Write a Dockerfile Build the container image Push the container to a registry Write Kubernetes manifests/Helm chart Deploy to Kubernetes draft init to configure your environment draft create to auto-create Dockerfile/Helm chart draft up to deploy to Kubernetes Inner loop development Set up a local dev environment using Minikube Determine the transitive closure of your dependencies Identify behavior of dependencies for key test cases Stub out dependent services with expected behavior Make local changes, check-in, and hope things work Validate with application logs Use Dev Spaces Do breakpoint debugging in your IDE Expose web apps to the internet with a DNS entry Deploy an ingress controller Create a load-balanced IP for it Add an ingress resource to your deployment Acquire a custom domain Create a DNS A-record for your service Turn HTTP application routing on in your cluster Add an ingress resource to your deployment
