http://stiller.co.il/blog/2014/01/upcoming-event-from-alm-to-devops/ 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),

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

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

Practically infinite resources on demand
• You need, they provide
• Lower costs
– Hardware
– Location-based

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

14. Introduction to Windows Azure
• Microsoft’s cloud
platform
• Windows Azure
provides IaaS & PaaS
• Microsoft also
provides SaaS with
Office 365 & Bing

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

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

• 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

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!

21. The Big Monitor in the Cloud
• Cloud-Services provide a build-in diagnostics module
– Azure Diagnostics API
Role Instance
Application

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

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! 
