Windows Azure Conference 2014 Running Docker on Windows Azure

Windows Azure Conference 2014 The Current State of Cloud IaaS has rapidly evolved in the last 3 years PaaS has matured into enterprise PaaS VMs are not portable across the IaaS vendors Every PaaS vendor follows a different deployment format IaaS needs Ops support DevOps is picking momentum There is an opportunity to make deployments more efficient 2

Windows Azure Conference 2014 Docker is the Shipping Container for Code 10

Windows Azure Conference 2014 Introducing Docker Open source engine to automate the deployment of any application as a lightweight, portable, self-sufficient container to run virtually anywhere Containers encapsulate any payload and consistently run on any server Common use cases for Docker include: – Automating the packaging and deployment of applications – Creation of lightweight, private PAAS environments – Automated testing and continuous integration/deployment – Deploying and scaling web apps, databases and backend services 11

Windows Azure Conference 2014 Separation of Concerns 12 Developers worry about what’s inside the container Code Libraries Package Manner Apps Data All Linux servers look the same Developers worry about what’s inside the container Code Libraries Package Manner Apps Data All Linux servers look the same Ops worry about what’s outside the container Logging Remote Access Monitoring Network configuration All containers start, stop, attach and migrate the same way Ops worry about what’s outside the container Logging Remote Access Monitoring Network configuration All containers start, stop, attach and migrate the same way

Windows Azure Conference 2014 What’s in it for Developers? Build once run anywhere – Clean, safe, hygienic and portable runtime for your app – No worries about missing dependencies and packages during deployment – Safely isolate applications in their own containers without worrying about conflicting versions, dependencies and packages – Automate everything – integration, packaging and deployment – Eliminate concerns about OS, platform and runtimes – Deploy in a VM without the overhead of VM – Instant replay and reset of image snapshots 15

Windows Azure Conference 2014 What’s in it for DevOps? Configure once…run everywhere – Make the lifecycle more efficient, consistent and repeatable – Increased the quality of code produced by developers – Efficiently manage development, test, staging and production environments – Separate roles & responsibilities – Significantly improve the reliability of continuous integration and continuous delivery – Simpler than managing VMs in terms of cost, performance, deployment and portability 16

Windows Azure Conference 2014 Virtual Machine and Containers Virtual Machine – Allow Multiple Guest OS to run together on a single machine – Each Guest OS abstracts Compute, Storage and Network Components – Hypervisor itself could run on bare-metal (ESXi) or be part of an OS (KVM) – Guest ISA is translated to Host ISA using multiple techniques like Hardware Virtualization or Binary Translation 17

Windows Azure Conference 2014 Virtual Machine and Containers Containers – Light weight containment system running – Runs instructions native to the core CPU – Container shares the Kernel and Process scheduler with the Host OS – No Binary Translation or VM exits – Containers can be run either directly on the Host OS or in a Guest VM 18

Windows Azure Conference 2014 Container vs. Virtual Machines 19 Containers are isolated but share OS and, where appropriate, binaries and libraries Containers offer significantly faster deployment, lesser overhead, easier migration and faster restart

Windows Azure Conference 2014 Why are Docker Containers Lightweight? 20 VMs Every app, every copy of an app and modifications of the app requires a new image Original App (No OS to take up space) Copy of the App (No OS. Shares Bins/Libs) Modified App Contains the diff between original container Containers
