3. What we Will Cover What is Azure Our “Enterprise” Application to Migrate Migrating to Infrastructure as a Service Migrating to Platform as a Service Migrating your data tier Migrating your app tier

4. What is the Microsoft Cloud: Azure Global Physical Infrastructure servers / network / datacenters Infrastructure N Central US, S Central US, N Europe, W Europe, E Asia, SE Asia + 24 Edge CDN Locations Automated Managed Resources Elastic Usage Based Services computestoragenetworking virtual machines web sitescloud services SQL database noSQL database blob storageconnectvirtual network traffic manager...... Fabric..............................

5. Option 1 – Infrastructure as a Service (IaaS) computestoragenetworking virtual machines web sitescloud services SQL database noSQL database blob storageconnectvirtual network traffic manager...... Fabric..............................

6. IaaS Costs Per Month Egress Costs (outgoing) 11.40 per 100GB in NA and Europe $18.05 per 100GB other locations Top package is over $55k a year Pre pay schemes can bring cost down by ~30% New High Memory options available (Sept 2013)

7. The IaaS performance story

8. Using IaaS – Pros and Cons Pros You can tell the CTO you have something in the cloud! Migration is easy Good resilience Fast provisioning Elastic resources No need to chat to the SAN guys ;-) Cons Not exactly “enterprise” class performance 100MB/Sec. Capped at 1,000 IOPS or 200MB/Sec Higher than on premise disk latency Limited Scale Up (8 cores) Your managing OS and binaries Not exactly “cheap” Sales guys will go straight to “TCO” and opex v capex discussions

9. Option 2 – Cloud Services computestoragenetworking virtual machines web sitescloud services SQL database noSQL database blob storageconnectvirtual network traffic manager...... Fabric.............................. Service Definition

10. Option 3 – Web Sites (PaaS) computestoragenetworking virtual machines web sitescloud services SQL database noSQL database blob storageconnectvirtual network traffic manager...... Fabric.............................. Web Site

11. Windows Azure SQL Databases (WASD) (AKA SQL Azure) Application Internet Azure Cloud Internet Azure Cloud LB TDS (tcp) Applications use standard SQL client libraries: ODBC, ADO.Net, PHP, … Load balancer forwards ‘sticky’ sessions to TDS protocol tier Security Boundary SQL Gateway Scalability and Availability: Fabric, Failover, Replication, and Load balancing Gateway: TDS protocol gateway, enforces AUTHN/AUTHZ policy; proxy to backend SQL

12. Objects NOT Supported Heap Table Types Change Data Capture Data Auditing Data Compression Extended Events Extension of spatial types and methods through Common Language Runtime (CLR) External Key Management / Extensible Key Management FILESTREAM Data Integrated Full-Text Search Large User-Defined Aggregates (UDAs) Large User-Defined Types (UDTs) Performance Data Collection (Data Collector) Policy-Based Management Resource Governor USE X Extended Properties Extended Stored Procedures SQL Server Agent/Jobs Common Language Runtime (CLR) and CLR User-Defined Types Database Mirroring Trace Flags System Tables Service Broker Table Partitioning Typed XML and XML indexing is not supported. (The XML data type is supported by SQL Azure Database) Global Temporary Tables Sp_configure SQL Server Replication Transparent Data Encryption SQL Server PowerShell Provider Backup and Restore Replication File Groups

13. Common Tools for Schema Migration Dacbac built into SSMS Migration Wizard (Codeplex) Generate TSQL Script SSDT (Visual Studio)

14. Common Tools for Data Migration BACPAC Deploy to Azure Wizard in SSMS BCPSSIS Third Party Tools

15. Suggested Approach For small databases use Migration Wizard For Medium databases use SSDT to validate Then BCP or bacpac For large databases use SSDT to validate Then BCP out, compress, transfer to cloud and bcp in A lot of benefit from making your on site version compatible with Azure Features Do try and go for parallel loading

16. Pricing and Sizes Size$/Month 0-100MB4.995 Up to 1GB9.99 1-10GB3.996 per GB over 1 10-50GB45.95 for first 10GB 1.996 per GB after that 50-150GB125.874 for 50GB 0.999 per GB after that * Plus Egress Network traffic costs

17. WASD – The Performance story

18. Why is WASD slightly slower than IaaS? In IaaS we hit a wall with disk performance In WASD slightly earlier wall Caused by change in table design (latch contention)

19. Option 3 – Scalability Next Steps

20. Azure Performance – Data Caching
