  • Windows Azure Platform in 30mins by ericnel

    1. 1. Technology Drill Down: Windows Azure Platform Eric Nelson | ISV Application Architect | Microsoft UK | |
    2. 2. Page 2 Assumption • Most of you are pretty new to the Windows Azure Platform • If you are not, check out: – –
    3. 3. Page 3 Agenda Overview of the Windows Azure Platform • Overview of the platform • Compute • Data Summary and Next Steps
    4. 4. Page 4 Overview
    5. 5. Page 5 Windows Azure Platform makes it easy and cost effective to run your applications and store your data inside Microsoft Data Centres using existing skills and integrate with your existing on-premise applications
    6. 6. Page 6 Windows Azure Platform
    7. 7. Page 7 You do most of your development locally
    8. 8. Page 8 Your code runs in Hosted Services made up of Roles
    9. 9. Page 9 Your Roles are code + configuration
    10. 10. Page 10 You choose which type(s) of Role to run your code in
    11. 11. Page 11 Load Balancer At runtime you can have multiple instances of your Roles http://yourapp.cloudapp.net
    12. 12. Page 12 You store your data in Windows Azure Storage
    13. 13. Page 13 And/or you store your data in SQL Azure
    14. 14. Page 14 Demo
    15. 15. Page 15 You have many choices for data Relational Database Structured Storage Unstructured Storage NTFS Drive Service Communication

    17. 17. Page 17 Demo
    18. 18. Page 18 Summary • Very easy to get going… but lots to learn • Plenty of early adopters, therefore – Good best practice are now appearing – Plenty of detail to dig into • Lots more coming

    20. 20. Page 20 Appendix
    21. 21. Page 21 Azure Drive (X-Drive) • Access to a Local Drive in Azure • Enables existing applications using NTFS to easily migrate to the cloud • Essentially a Page Blob formatted as NTFS – Remote Access via Page Blob Interface • Durable NTFS volume [upto 1TB] for Windows Azure Applications • Drives in the Cloud are only mountable by VMs within Cloud – Mounted by one VM at a time for read/write – A VM can dynamically mount up to 16 drives
    22. 22. Page 22 Page Blob Azure Drive Local Cache Application Drive X: Azure Drive - Scenario • The Application Mounts a Drive • Mount obtains a Blob Lease • Mount specifies size of Local Cache • NTFS Writes update the – Blob Store & then the Local Cache • NTFS Reads can be served from – Local Cache or – Blob Store (cache miss)Lease
    23. 23. Page 23 Azure Table and SQL Azure Table Feature Azure Table SQL Azure Table Partitioning & Scale Implicit based on Partition Key Explicitly managed by the Application (Sharding – future feature) Index Capabilities Table indexed on Partition Key + Row Key 0 Secondary Indexes 1 Clustered Index on any column 999 Secondary Indexes Table Limits Row Size – 1 MB Column Limit – 255 Table Limit – 100TB Row Size – 8MB Column Limit – 1024 Table Limit - ~50GB Transactions Transactions on entities within partition No Transactions across tables or partitions Up to 100 operations in a Transaction Payload upto 4MB per Transaction Fully compatible transactional semantics with SQL Server. No cross Database transactions Consistency Model Transactionally Consistent Transactionally Consistent Concurrency Single Optimistic Concurrency Strategy Full range of isolation and concurrency models as supported by RDBMS
    24. 24. Page 24 Azure Table and SQL Azure Table Feature Azure Table SQL Azure Data Access REST API, ADO .NET, Client Library SDK Standard tools and APIs apply SSMS, Visual Studio, ADO .NET, ODBC Column Types Basic Types Usual SQL Server Data Types Portability Data portability coming with Windows Azure Appliance Data in SQL Azure similar to SQL Server -Easy migration in and out of the cloud -Use multi stream transfer to mitigate network latency. Queries Upto 1000 entities [token pagination] Beyond 5 sec – return continuation token Queries by partition & row key are fast No Custom Indexes Today Non key queries are scans Query capabilities as per standard SQL Server database expectations Offer Server Side Processing through Stored Procedures and Complex Queries (Aggregation, Joins, Sorts, Filters, etc.)
