4. Delivering modern web applications with Kubernetes and OpenSource Technologies
5. Objective: Understand WHY Rather than HOW! Container Orchestration Azure Container Registry DEMO Release automation tools Containers 101 Azure Kubernetes Service (AKS) Kubernetes Concepts
6. Through the presentation we will be creating some resources If you want to replicate the demos of this talk plz refer to: On GitHub search for vcach user to access the repo: GAB2018-Kubernetes https://github.com/vcach/GAB2018-Kubernetes AKS Workshop: https://github.com/Azure/blackbelt-aks-hackfest
7. Containers 101 Containers 101
8. From Traditional App to Modern App Existing Application APP Modern Microservices Add new services or start peeling off services from monolithic code. Modern Infrastructure Rehost as VMs or refresh to modern container platform. Containerize Applications Re-architect apps for scale with containers. Containers Container Platform On-Premises Infrastructure Platform PaaS Application Platform Serverless IaaS Infrastructure Platform “lift & shift”
9. What we hear from Developers I need to create applications at a competitive rate without worrying about IT New applications run smoothly on my machine but malfunction on traditional IT servers My productivity and application innovation become suspended when I have to wait on IT
10. What we hear from IT I need to manage servers and maintain compliance with little disruption I’m unsure of how to integrate unfamiliar applications, and I require help from developers I’m unable to focus on both server protection and application compliance
11. What is a Container? Containers = operating system virtualization OS Kernel Applications Container Container Container Hardware Traditional virtual machines = hardware virtualization Hardware OS Application VM VM VM App OS App OS App OS
12. VMs versus Containers Virtualization Containerization Type 1 Hardware Hypervisor 1 VM VM VM Hardware Type 2 Host OS Hypervisor 2 VM VM VM Virtual machine Guest OS Dependencies Application Hardware Host OS Docker Engine Dependency 1 Dependency 2 C C C C C Container App dependencies Application XYZ
13. The Container advantage Hardware Host OS Docker Engine VM VM Con. Con. Con. Con. Containerized environment Migrate containers and their dependencies to underutilized VMs for improved density and isolation Decommission unused resources for efficiency gains and cost savings
14. The Container advantage Fast iteration Agile delivery Immutability Cost savings Elastic bursting Efficient deployment For IT For developers
15. Azure Container Registry (ACR) Azure Container Registry
16. Azure Container Registry (ACR) Manage a Docker private registry as a first-class Azure resource Use familiar, open- source Docker CLI tools Azure Container Registry geo-replication Manage images for all types of containers
17. Container Orchestration Container orchestration
18. The elements of Orchestration Scheduling Affinity/anti- affinity Health monitoring Failover Scaling Networking Service discovery Coordinated app upgrades
19. Orchestrator Options
20. Kubernetes Concepts Kubernetes Concepts
21. Kubernetes, The de-facto orchestrator Portable Public, private, hybrid, multi-cloud Extensible Modular, pluggable, hookable, composable Self-healing Auto-placement, auto-restart, auto-replication, auto-scaling
22. Kubernetes, Empowering you to do more Deploy your applications quickly and predictably Scale your applications on the fly Roll out new features seamlessly Limit hardware usage to required resources only
23. Kubernetes Architecture api-server etcd controller-manager scheduler kubelet kube-proxy docker dns master components node components * Azure Managed
24. Main Kubernetes concepts Services are an abstraction for a logical set of Pods. Pods are the smallest deployable units of computing Deployments provide declarative updates for Pods and RCs. Replica Sets ensure specified number of Pods are running Labels are key/value pairs attached to objects used for identification
25. Azure Kubernetes Service (AKS) Azure Kubernetes Service (AKS)
26. Azure Kubernetes Service (AKS) Simplify the deployment, management, and operations of Kubernetes Work how you want with open- source APIs Scale and run applications with confidence Focus on your containers not the infrastructure
27. Azure Kubernetes Service (AKS) A fully managed Kubernetes cluster Managed Azure infrastructure services Docker Kubernetes • Managed control pane • Automated upgrades, patches • Easy cluster scaling • Self-healing • Cost savings Application architect Infrastructure architect Applications Operations
28. Release Automation Tools - DevOps Release automation tools
29. DevOps Why? Deploy 200 times more frequently Go from code check-in to production 2,555 times faster Recover from failure 24 times faster Spent 50% less time remediating security challenges Spent 22% less time on unplanned work 2.2 times more likely to believe their places a great place to work Source: https://puppet.com/resources/white-paper/2016-state-of-devops-report
30. DevOps Toolset
31. Release Automation Tools Simplifying the Kubernetes experience Streamlined Kubernetes development The package manager for Kubernetes Event-driven scripting for Kubernetes Visualization dashboard for Brigade
32. Demo Time DEMO
33. DEMO Architecture What we already create: - Docker Image - Resource Group - Azure Container Registry - Kubernetes Cluster - Brigade and Kashti
34. Thanks! Any questions?
