HA and Elastic Scaling... It's Easy on Azure

Azure is a fast growing collection of integrated cloud services. With these powerful services, it is easy to achieve high availability and elastic scaling. During this talk, I will show you exactly just how easy it is. He will be sharing a few tips and tricks that he picked up during his journey as well as any stumbling blocks he hit on the way.

4. Azure Is Coming To South Africa!!!
5. What Is Azure? § Microsoft Azure is a growing collection of integrated cloud services that developers and IT professionals use to build, deploy, and manage applications through their global network of datacenters.
7. On Premises You scale, make resilient and manage Infrastructure (as a Service) Managed by vendor You scale, make resilient & manage Platform (as a Service) Scale, resilience and management by vendor You manage Software (as a Service) Applications Scale, resilience and management by vendor Why The Cloud?
8. Common Scaling Problems
9. § By default, PHP stores sessions in files § This does not carry across multiple servers Common Scaling Problems #1 Session Storage
10. § Cloud servers should be thought of as utility resources § They can be created and destroyed as required § Use a share-nothing design § Each node is independent and self-sufficient Common Scaling Problems #2 Thinking Servers Will Run Forever
11. § Local storage should only be used as temporary storage § Use network storage for configuration or long-lived files Common Scaling Problems #3 Using Local Storage
12. § Multiple approaches § Read replicas § Multi-masters Common Scaling Problems #4 Not Scaling DB
13. § Monolithic application handles requests as well as all background processing § Separate concerns by moving background processing to worker queue Common Scaling Problems #5 No Distributed Processing
14. § Elasticity requires proper deployment plan § Runtime errors during deployment § All hosts require same version to prevent requests from behaving differently Common Scaling Problems #6 Deployment
15. § Session Storage § Servers Are Utility Resources § Local Storage § Scaling DB § Distributed Processing § Deployment Common Scaling Problems Summary
16. Going HA and Elastic With Azure…
18. § Elasticity for free § Deployment for free § Easy to manually scale up or out § Scaling up = Vertical Scaling § Scaling out = Horizontal Scaling § Easy deployment Azure Components #1 Introducing App Services
19. § App Service For Linux uses Docker containers § Code is deployed to “/home/sites/wwwroot” § Kudu mounts “/home/sites” into the container § Default containers for PHP 5.6 and 7.0 § https://github.com/Azure-App-Service/php § Tangent Solutions Containers § Laravel § Symfony Getting Your Application Ready #1.1 Using App Services
20. § Session Storage § Servers Are Utility Resources § Local Storage § Scaling DB § Distributed Processing § Deployment Common Scaling Problems Checklist
21. § DB as a service § Easy to scale § Managed: § Patching § Backups § Monitoring § Security Azure Components #2 Introducing Azure DB For MySQL
22. § Session Storage § Servers Are Utility Resources § Local Storage § Scaling DB § Distributed Processing § Deployment Common Scaling Problems Checklist
23. § Serverless § Multiple languages § Amazing integration Azure Components #3 Introducing Azure Functions
24. § Replaces Cron Jobs § + More § Examples: § Monitor Blob Storage for a new file and create required thumbnails § Run scheduled imports from external DB § Run scheduled complex computations such as pricing changes etc… § Send scheduled reports from application DB Azure Components #3.1 Using Azure Functions
