  1. LightSwitch 2011 with Azure Andrew Butenko http://andrewbutenko.wordpress.com @andrew_butenko Intermediate level

  2. Objectives and Takeaways Session Objectives • You will understand the existing and upcoming capabilities of Microsoft Azure cloud and LightSwitcn 2011 • Know how to choose you architecture blocks • Restrictions • LightSwitcncombined with Azure benefits Goals • Understand at the end the existing and upcoming deployment aspects of Lightswitcn and Azure • Learn how to optimize your design. • Do it as simple as possible

  3. Architecture Decision Matrix

  4. Infrastructure as a Service

  5. Platform as a Service

  6. Platform as Service Security Model

  7. Hybrid solutions

  8. Private or Public?

  9. Windows Azure Service Model • A windows Azure application is called a “service” • Definition information • Configuration information • At least one “role” • Roles are like DLLs in the service “process” • Collection of code with an entry point that runs in its own virtual machine • Windows Azure compute SLA requires two instances of each role • 99.95$ for connectivity to two instances • Achieved with update and fault domain Data Centre’s Node Virtual Machine Windows Azure Roles

  10. Multi-Instance approach • Automated, consistent application update • Automated, consistent configuration changes • Multi-instant management • Scale out • High availability • Automated, consistent OS security

  11. Application Security • Session Management • Cryptography • Parameter Manipulation • Exception Management • Auditing and Logging • Input Validation • Authentication • Configuration Management • Sensitive Data

  12. Identity in the cloud

  13. Federated Security

  14. Transport security

  15. Windows Azure Code Access Security

  16. AppFabric Access Control Service • Provides rules-driven, claim-based authorization • Web application • REST Web service • SOAP Web service • Key features • Broad identity providers support • AD Federation Services v2.0 • Live ID, Facebook, Google, Yahoo • Private Identity Store • WS-Trust and WS-Federation protocol support • Full integration with Windows Identity Foundation (WIF) • Configurable through new management web portal

  17. Access to data Transfer: • BCP • SSIS • SQL Azure Migration Wizard • SQL Server Migration Assistant Connect: • Windows Azure Connect (*) • Windows Azure AppFabric Access Control Service (ACS)

  18. Windows Azure Connect

  19. On-Premises Synchronisation

  20. SQL Types Restrictions

  21. Components

  22. Main Parts

  23. Web application model

  24. Windows Azure Storage

  25. Protection Against Data Loss

  26. BLOB Model

  27. Windows Azure Queues • Provide reliable message delivery • Simple, asynchronous work dispatch • Programming semantics ensure that a message can be processed at least once • Queues are highly available, durable and performance efficient • Maximum size is 64K • FIFO in general, but not guaranteed (compare with SQL Broker and MSMQ) • Pulling an item from the queue doesn’t delete it • It becomes invisible for a visibility timeout • Item must be deleted before timeout or else it becomes visible

  28. Deployment • VS publishing • Deploy DB wizard • PowerShell

  29. PowerShell Tasks • Deploy new hosted services • Upgrade services. Swap VIP between staging and production. • Remove Hosted Services .Automatically stop services and stop the billing cycle. • Manage Storage Accounts. Retrieve or recreate storage keys • Manage Certificates. Deploy certificates • Configure Diagnostics. Configure event sources to monitor (Event Logs, Tracing, IIS Logs and Performance Counters) • Transfer Diagnostic Information. Schedule diagnostics transfers or have them execute on demand. New-Deployment -serviceName <servicename> -subscriptionId <subscriptionid> -certificate <certificate> -slot staging -package <packagefile> -configuration <configfile> -label <servicelabel> | Get-OperationStatus –WaitToComplete

  30. Windows Azure changes Feb 2012 Pay-As-You-Go rates: • Windows Azure • Compute • Extra small instance: $0.02 per hour • Small instance (default): $0.12 per hour • Medium instance: $0.24 per hour • Large instance: $0.48 per hour • Extra large instance: $0.96 per hour • Storage • $0.125 per GB stored per month • $0.01 per 10,000 storage transactions • Content Delivery Network (CDN) • $0.12 per GB for data transfers under Zone 1 • $0.19 per GB for data transfers under Zone 2 • $0.01 per 10,000 transactions • Virtual Network • Windows Azure Connect - No charge during CTP • Access Control • $1.99 per 100,000 transactions • Service Bus • $0.10 per 100 relay hours • $0.01 per 10,000 messages • Caching • 128 MB cache for $45.00 • 256 MB cache for $55.00 • 512 MB cache for $75.00 • 1 GB cache for $110.00 • 2 GB cache for $180.00 • 4 GB cache for $325.00

  31. Azure Pricing • What we are paying for? • How to minimize cost? • How to avoid over limiting? • Hidden costs • Extension prices • What is on special? • Current price policy

  32. SQL and Transfer Pricing • SQL Azure • Database Size Price Per Database Per Month 0 to 100 MB Flat $4.995 Greater than 100 MB to 1 GB Flat $9.99 Greater than 1 GB to 10 GB $9.99 for first GB, $3.996 for each additional GB Greater than 10 GB to 50 GB $45.954 for first 10 GB, $1.998 for each additional GB Great than 50 GB to 150 GB $125.874 for first 50 GB, $0.999 for each additional GB • Data Transfers • Zone 1 • $0.12 per GB out • Zone 2 • $0.19 per GB out • All inbound data transfers are at no charge. • 1 Compute hours are calculated based on the number of hours that your application is deployed. Details on different compute sizes are summarized in the table below

  33. Billing • Pay as you go  • Pay as you grow  • Pay as you here 

  34. Billing statistics

  35. Monitoring

  36. Technical support

  37. Ready to cloud? • Check restrictions • Run script directly • Deploy from VS2010/11 • Compare schemas in VS11 SQL Database project

  38. LightSwitch 2011?

  39. Restrictions and limitations

  40. Keep in mind • No *nix/Android/IOs support. Moonlight plans to support SilverLight 4.0 but not 5.0 yet. • Migration LightSwitch project from VS 2010 to VS 11 is not straightforward. • Windows XP is not compatible with VS 11. • LS Extensions in VS 2010/11 and Desktop/Web are different • Excessive memory usage when you debug in VS (memory leaks) • Disable Export to Excel feature to improve performance • Table relationships in VS2010 are not allowed in external datasource (fixed in VS 11). Views are not editable (without PK) • Linqdoes not always pick up external datasource. Use iterators  • For security purposes, you can’t buy a certificate mapping to the yourapp.cloudapp.net. Only Microsoft can issue certificates for cloudapp.net, though you can create your own self-signed certificate for development purposes. • Computed fields are not directly available in queries and relationships • No deny, only allow permissions - User.HasPermission()

  41. Development aspects • LightSwitchproject architecture (logical vs physical) • Customisation and extension (grab-and-go) • Logical /physical structure of project (Client, Common, Server) • Relationships(1-1|0; 1|0-*; *-*) • Adding pages with parameters (binary encoding) • Localisation. Display names, Money symbols, Languages • Accessing security data (from API or external datasource) • Desktop (works good) -> Web (partially) -> Azure (does not work) • Validation (check input data, prevent big pictures, etc) • Audit, exception handling • Permissions as an application security blocks, User.HasPermission() • Screen navigation

  42. Demo1 • LS application anatomy
