1 Application Migration Best Practices Gregory Shepard Senior Consultant InCycle Software

2 We Help Organizations Get to the Next Level ALM MVPs and ALM consultants in six locations

3 Application Migration Best Practices You should be able to answer these questions: Cloud Service or Web Site (App Service)? What Azure features drive code refactoring? How should I monitor and identify problems in my deployed application? What three proven security measures show up in secure Cloud applications?

6 Cloud Service or App Service?

7 App Service (Websites) Simple to complex scenarios, streamlined mgt. tools. Custom Web Apps Non-web WebJobs Prod / Staging Slots

8 Cloud Service App Service workloads+ Web/Worker Role entry, app lifecycle Complex workloads, task oriented processes

9 Leverage Azure Features: Messaging Cheap Storage Fast Data Access Async Operations

10 Use Azure Active Directory Access Control Authentication & Authorization out of your code! Standards support: WIF, LiveID Google, Yahoo, Facebook JWT, SAML, SWT Odata

11 Leverage Azure Storage Loosely couple components Use Messaging Queues with Worker Roles or WebJobs for tasked base or fire-forget processes Favor Blob Storage over local file system Use Table Service for reference data vs MSSQL

12 Use External Configuration Store(s) Centralize application configuration data Reachable by all instances Minimize management workload Use pattern to keep Web Instances stateless, moving session to external provider(s)

13 Use Azure CDN for Static Content Content Delivery Network is reachable by all instances Reduces compute usage (cpu) Globally distributed Centrally managed Minimize management workload

14 Retry for Success Request 1 Fails Retry 2 Fails Retry 3 Succeeds Request Succeeds

16 Identity and Authentication For Emphasis: Remove Authentication & Authorization from your code base Use Standards or standards based services Odata, Azure ACS

17 Use Secure Communications Use Azure VNet to connect cloud services, web apps, databases, etc. Connect on premise to Azure using a VPN (Point, Site) or ExpressRoute Use Azure Security Groups to control traffic to/from VNet

18 Protect data Use SSL with sensitive data Encrypt application data and config. Values like connection strings Consider encrypting SQL data

19 Azure Application Insights Logging Tracing Debugging Diagnostics Code Refactoring

20 Availability Scalability Instrumentation Health Monitoring Scale: Bigger, Better, Faster Script repeatable operational tasks Test Load Test

21 Instrument your app Use Tracing and Debug statements in code Use Diagnostics in Role Instances Enable RDP in Roles Enable App / Role Monitoring in Azure Portal

22 Use Azure Application Insight Great Analytic Tools Easy to leverage What you can get Performance and usage analytics for ASP.Net or Java application Get Additional Azure web app telemetry SDK for development Portal for Management What to do Application Insights SDK to your web project Enable Insights in your Azure web app Usage analytics for web pages from any server Monitor availability of your website Insert the Application Insights script into your web pages Create web tests

23 Use Azure Application Insight

24 Scale Out your application

25 Optimize Web Requests

26

27 Best Practices: Summary Favor App Service over Cloud Service Refactor for: Storage, Message Queue, Chunky Data, Caching and Azure Table Service Instrument your code trace/debug/diagnostic logging and leverage Application Insights Secure data communications, encrypt your data, secure connection strings

28 Better, Faster, Smarter Automate everything! Adopt Continuous Integration Use source control
