How do companies like Microsoft, Twitter, Facebook and LinkedIn achieve high levels of execution which allow implementing hundreds and even thousands of lines of code every day, while maintaining a high & consistent level of performance, security and availability? How can the development and operation environments work together to create a meaningful competitive edge for the organization?

In an era where time-to-market and product quality have a critical meaning, the DevOps methodology offers simple and effective ways to shorten schedules, improve the product quality and maintain a competitive edge.

In this presentation, which is part of the "From ALM to DevOps" day, I explain and demonstrate the principles of DevOps in Windows Azure. Also demonstrated is the possible synchronization between Team Foundation Server (TFS) and Microsoft System Center (SCOM),

  • 5. About OzCode • • • • • • An innovative debugging extension for Visual-Studio Simplify & visualize complex statements Compare objects and collections Search and filter collections Focus on relevant data http://oz-code.com 5
  • 6. Introduction to Cloud Computing Cloud Computing - A Game Changing Technology • Infinite shared resources & services – Infrastructure is not a limiting factor – No need to equip for peak-load requirements • Elasticity on demand – Anytime, anywhere • Efficient scalability and high availability • Suitable pricing models – Pay for what you use 6 DevOps in the Cloud
  • 7. Cloud Computing Evolution of Computing - The Next (Current) Big Thing • Virtualization and Abstraction – Details are abstracted from consumers • Reduces complexity • Not necessarily the Internet, can be on premises – Private cloud • Automation, Monitoring, Deployment – Reduce cost, shift risk, shorten time-to-market, focus on business functionality 7 DevOps in the Cloud
  • 8. Less Worries Focus on functionality • Let others take care of: – – – – – – – – 8 Resource management Security Environments (staging, production) High availability, scalability, load balancing Fault tolerance OS - installation, licensing, updates, patches Network Maintenance DevOps in the Cloud
  • 9. Cloud Containers Practically infinite resources on demand • You need, they provide • Lower costs – Hardware – Location-based • • • • 9 Power (electricity) Cooling Networking Good coverage DevOps in the Cloud
  • 10. Cloud Containers 10 Cloud Architecture Challenges
  • 11. Cloud Fundamentals • Infrastructure as a Service (IaaS): – Compute, network, storage resources – On-demand servers – E.g. Amazon EC2, Rackspace, HP Cloud, Windows Azure • Platform as a Service (PaaS): – Operating systems and application infrastructure – On-demand application-hosting environment – E.g. Google AppEngine, Salesforce.com, Windows Azure, Amazon • Software as a Service (SaaS): – On-demand cloud applications – E.g. Gmail, Office 365, Facebook 11 DevOps in the Cloud
  • 12. The Benefits of the Cloud The Cloud is about cheap, on-demand capacity = Managed for you Standalone Servers IaaS Applications Runtimes Database Operating System Virtualization Server Storage Networking 12 Cloud Architecture Challenges PaaS SaaS
  • 13. Cloud Computing Overview Summary Cloud Computing is the natural computing evolution • Deliver high end quality applications – In cheaper costs – In shorter time – In less risks 13 DevOps in the Cloud
  • 14. Introduction to Windows Azure • Microsoft’s cloud platform • Windows Azure provides IaaS & PaaS • Microsoft also provides SaaS with Office 365 & Bing 14 DevOps in the Cloud
  • 15. Introduction to Windows Azure • Three ways to host a web application – Azure Web-Sites (PaaS) – Azure Cloud-Services (PaaS) – Azure Virtual-Machines (IaaS) • Not all PaaS services are born equal – Cloud-Services allow more control than Web-Sites 15 DevOps in the Cloud
  • 16. ALM In-Practice • Our demo comprises of a simple Web-Application – Hosted in an Azure Cloud Service • Source code managed in Team Foundation Server (TFS) • Continuous integration provided by TFS build server • Separate code branches for various software stages – Development – Staging (QA) – Production 16 DevOps in the Cloud
  • 17. ALM In-Practice Dev TFS “Dev” Branch TFS Build Continuous Integration Local Dev Tests QA TFS “Staging” Branch TFS Build Continuous Deployment Azure Staging Env. IT TFS “Prod.” Branch TFS Build Continuous Deployment Azure Production Env. 17 DevOps in the Cloud
  • 18. ALM In-Practice • Staging & Production environments deployed in the cloud – Continuous Deployment to the cloud • Automatic one-click deployment – Provided by TFS Build Server – Use Release Management for more complex scenarios 18 DevOps in the Cloud
  • 19. DevOps in the Cloud ALM IN THE CLOUD
  • 20. Monitor Your Application • Cloud hosted application are not immune to crashes – The physical host can fail • Deploy multiple instances • Guarantee SLA – The OS can crash • Windows/Linux – Your application MIGHT have bugs… • QA can’t always help • You should monitor your application! 20 DevOps in the Cloud
  • 21. The Big Monitor in the Cloud • Cloud-Services provide a build-in diagnostics module – Azure Diagnostics API Role Instance Application Code Local Storage 21 Diagnostics Monitor IIS Logs Event Logs Perf. Counters DevOps in the Cloud Azure Storage
  • 22. The Big Monitor in the Cloud • Various tools exist which can read Azure diagnostics – – – – – Visual Studio Azure Management Portal Azure Storage Explorer Azure Diagnostics Manager Microsoft System Center Operation Manager (SCOM) • Choose the tools most appropriate for you 22 DevOps in the Cloud
  • 23. DevOps with TFS & SCOM • TFS & SCOM can synchronize “Production Issues” • Allows for coordination between IT and Development – Close issues quickly & easily – Less friction – Everybody is happy!  23 DevOps in the Cloud
