The document discusses strategies for effectively running, improving, and maintaining web sites in real-world environments. It covers scaling, adapting to changes, and managing multiple environments, emphasizing solutions like using blob storage for static files, caching in Azure, and continuous integration for deployment. Specific scenarios described include managing database schemas, leveraging cloud services, and ensuring environment consistency across deployments.
Running, improving & maintaining a site in the real world
- 1. Running, improving and maintaining a site in the real world Dave Voyles Dvoyles@Microsoft.com
- 2. Agenda 1) Scenario: Scale 2) Scenario: Adapt to Change 3) Scenario: Environments
- 5. Scenario description Your site load varies over time. You need to adapt. Smoothly. 5
- 7. Step 1: Preserve server bandwidth PROBLEM: Your servers are wasting bandwidth serving static files. 7
- 8. Step 1: Preserve server bandwidth SOLUTION: Serve static files from blob storage. This is a step towards to delivering content from a content delivery network (CDN). 8
- 9. Step 2: Caching PROBLEM: Your servers have finite resources. You don’t want to repeat work you don’t have to. 9
- 10. Step 2: Caching SOLUTION: Store ASP.NET page output cache in Windows Azure Caching Service. 10
- 11. Step 3: Manual scale PROBLEM: You need more server resources. 11
- 12. Step 2: Manual Scale SOLUTION: Add more servers (horizontal scaling). Use more powerful servers (vertical scaling). 12
- 13. 13
- 14. Step 3: Auto-scale PROBLEM: Manual scaling reaction time means outages. Manual scaling is busy work. 14
- 15. Step 2: Auto-scale SOLUTION: Use auto-scale. 15
- 16. 16
- 18. Scenario: Change
- 19. Scenario description Your site isn’t done when you deploy to production. You need to add new features. Change adds risk. 19
- 20. Step 1: Manage database schema PROBLEM: Your database and application code need to stay in sync. 20
- 21. Step 1: Manage database schema SOLUTION: Use Entity Framework Data Migrations. 21
- 23. Step 2: Manage deployments PROBLEM: People sometimes make misteaks. 23
- 24. Step 2: Manage deployments SOLUTION: Use deployment rollback. 24
- 25. 25
- 27. Step 3: Leverage services PROBLEM: Large changes often require you to add new features quickly. 27
- 28. Step 3: Leverage services SOLUTION: Take advantage of available Windows Azure services. 28
- 29. Demo Scenario: Windows Azure Active Directory
- 31. Scenario description Running a real site requires multiple internal environments. Global availability requires multiple worldwide deployments. 31
- 32. Step 1: Dev / Test environments PROBLEM: Setting up development web server environments is time consuming. You need to see your code running somewhere other than deployment before deploying. 32
- 33. Step 1: Dev / Test environments SOLUTION: Environment consistency via deployment setup in Windows Azure Web Sites or VM images. Cost savings by paying only for what you need. 33
- 34. DISCOUNT VIRTUAL MACHINES 33% 25%DISCOUNT RESERVED WEB SITES CLOUD SERVICES, HDINSIGHT MONTHLY CREDIT VISUAL STUDIO ULTIMATE WITH MSDN $150 CREDIT CARD REQUIRED NO MONTHLY CREDIT VISUAL STUDIO PREMIUM WITH MSDN $100 MONTHLY CREDIT VISUAL STUDIO PROFESSIONAL WITH MSDN $50
- 35. Step 2: Global Reach PROBLEM: It’s hard to deploy a consistent environment in multiple datacenters. 35
- 36. Step 2: Global Reach SOLUTION: Use automated deployment workflow to ensure consistency in deployment process. 36
- 37. Step 3: Continuous Delivery PROBLEM: Bugs and issues in your code get harder to fix the longer it takes to find out about them. Deployment is a risky, error-prone operation. 37
- 38. Step 3: Continuous Delivery SOLUTION: Use continuous integration to automate build, unit & integration testing. Use automated deployment workflow to ensure consistency in deployment process. 38
Editor's Notes
- #35: Fastest Growing Hypervisor, taking share from VMWare” 2 releases of Hyper-V since ESX 5.1 (WS2012 and WS2012 R2) Hyper-V share is growing 3x that of VMW over the past 2 years Hyper-V steadily taking over a point of share per quarter Microsoft in the Gartner Virtualization Magic Quadrant for the 3rd straight year and is the only vendor moving up and to the right Over 50 new services released this year Compute & Storage Capacity doubling every 6 – 9 months
