1 Alan Smith – KnowIT Consulting

2 Agenda  Oslo Repository Database “M” Language “Quadrant” modelling tool  “3 Dubs” Windows Communication Foundation 4.0 Windows Workflow Foundation 4.0 Dublin Application Server  How will this affect BizTalk? Dublin and BizTalk

3 About Alan Smith  Connected Systems Consultant – KnowIT Developer, Trainer, Mentor, Evangelist  MVP – “Connected Systems Developer” Former MVP for BizTalk Server  Microsoft Connected Technology Advisor Strong contacts with CSD development team in Redmond  bloggersguides.net bloggersguides.net Connected Systems community portal Bloggers Guide to Connected Systems Bloggers Guide to BizTalk Webcasts & Articles  Community address, feel free to bug me with questions!

4 “Connected Systems”  Connected Systems Division (CSD) One of the largest divisions in Microsoft  “Connected Systems” products and technologies BizTalk Server WCF/WF 4.0 Codename “Dublin” Codename “Oslo” Windows Azure

5 Current Connected Systems Story .net 3.5 WCF ○ Foundation for developing connected applications WF ○ Foundation for developing workflow based applications  BizTalk Server 2006 R2 Integration Server ○ Messaging Engine ○ Orchestration Engine ○ Trading Partner Management ○ EDI ○ Adapters

6 Emerging Connected Systems Technologies  Oslo Modeling platform Repository database, graphical editor, modeling language  WCF/WF 4.0 Tighter integration between WCF and WF Ability to create declarative services Major changes in WF class library Great improvements in XAML support Improved activity designers  Dublin Application server Host for WCF Services and WF Workflows  Azure Windows “in the cloud” Provides a number of services hosted by Microsoft  BizTalk Server 2009 Integration Server

7 Oslo – October 2007  Modeling tool  Repository database  Process runtime  BizTalk Server vNext  Systems Center components  WCF vNext  WF vNext  Visual Studio vNext  Cloud based services

8 Oslo – September 2008  Repository Database Built on SQL Server 2008 Stores model definitions (structure) Stores model instances (data)  “M” language Declarative text-based modeling language Can be used to define models for repository database  “Quadrant” modeling tool Graphical tool used to edit model instances Targeted at “Business Analysts” and architects

9 Repository Database  Storage for model definitions and model instances  SQL Server 2008 database  Transparent data access Various tools can be used to query repository

10 Repository Database Content  Tables in the Repository database represent different technologies  Currently included: Common language runtime Windows Communication Foundation Windows Workflow Foundation Identity  Future technologies will be “Schematized” BizTalk Server

11 Types of Models  Structural Models Model definitions Represented by table structure  Instance Models Model instances Represented by data in structural model tables

12 Structural Models  Database structure is used to define models  The WCF artefacts are represented as tables in the repository database Service contracts Operation contracts Endpoints Bindings

13 System.ServiceModel partial structure

14 Instance Models  Data is used to define models  Rows are inserted in structural model tables  A service application can be modelled by Adding a service contract Adding service operations Adding endpoints and bindings

15 “M” Language  Textural based modelling language Aimed at “Curly-brace” programmers “Because graphical tools slow us down.” – Don Box  Different types of “M” MSchema – Used to define database schemas MGrammar – Used to define domian specific languages MService – Used to define service implementations

16 Using “M” to Model BizTalk Server // module is equivalent to.net NameSpace module Microsoft.BizTalk { // type is a declaration of an entity type BizTalkGroup { Id : Integer32; Name : Text; MgmtDbServer : Text; MgmtDbDatabase : Text; } where identity Id; // An extent of zero or more types BizTalkGroups : BizTalkGroup*; type BizTalkServer { Id : Integer32; Name : Text; Group : BizTalkGroup; } where identity Id; BizTalkServers : BizTalkServer* where item.Group in BizTalkGroups; }  MSchema is used to model data structures, storage, views and constraints  BizTalk artefacts are “Schematized”  “M” code is compiled to a module  Module is imported into repository database

17 Compiling to “Reach” SQL  “M” models can be compiled to TSQL ““M” is to TSQL what C is to assembly” – Don Box  TSQL can be used to create repository structure or standard database structure Repository TSQL is more complex // module is equivalent to.net NameSpace module Microsoft.BizTalk { // type is a declaration of an entity type BizTalkGroup { Id : Integer32; Name : Text; MgmtDbServer : Text; MgmtDbDatabase : Text; } where identity Id; // An extend of zero or more types BizTalkGroups : BizTalkGroup*; type BizTalkServer { Id : Integer32; Name : Text; Group : BizTalkGroup; } where identity Id; BizTalkServers : BizTalkServer* where item.Group in BizTalkGroups; } set xact_abort on; go begin transaction; go set ansi_nulls on; go create schema [Microsoft.BizTalk]; go create table [Microsoft.BizTalk].[BizTalkGroups] ( [Id] int not null, [MgmtDbDatabase] nvarchar(max) not null, [MgmtDbServer] nvarchar(max) not null, [Name] nvarchar(max) not null, constraint [PK_BizTalkGroups] primary key clustered ([Id]) ); go create table [Microsoft.BizTalk].[BizTalkServers] ( [Id] int not null, [Group] int not null, [Name] nvarchar(max) not null, constraint [PK_BizTalkServers] primary key clustered ([Id]), constraint [FK_BizTalkServers_Group_Microsoft.BizTalk_BizTalkGroups] foreign key ([Group]) references [Microsoft.BizTalk].[BizTalkGroups] ([Id]) ); go commit transaction; go Compile

18 IntelliPad Editing Tool  Simple text based code editor  Supports “M” languages  Provides instant feedback of code compilation Great for learning “M” languages  Visual Studio can also be used for “M” Most likely scenario in real projects

19 IntelliPad Editing Tool  Modelling data in IntelliPad  TSQL code is created instantly

20 Visual Studio – Oslo “M” Project Template  “M” data models can be developed in Visual Studio Projects are better structured Source control integration Visual Studio can build projects More suitable for larger projects  Repository “M” Source code Product.mproj in Oslo SDK Contains “M” models used to create repository structure

21 Demo: Modelling BizTalk Server using “M”  In this demo you will see IntelliPad text editor Basic “M” syntax Generating TSQL Compiling “M” to a module Importing content into Repository database

22 My Opinions on the Repository Database Camelot! It’s only a model

23 The Repository Contains Models  Alan's opinion... The repository database contains models Models can be structural (tables) Models can be instances (data)  I could be wrong though...

24 The Repository Contains Models  Alan's opinion... Runtime configuration information will not be stored in the repository ○ Applications will be modelled in the repository database ○ The repository models will be used to create running applications ○ Running applications will have their own runtime database ○ The runtime database structure may well mirror the repository structure  I could be wrong though...

25 The Repository Contains Models  Alan's opinion... Business data will not be stored in the repository ○ Business models will be defined in “M” ○ The “M” models will be used to add the business model definition to the repository ○ These models will be used to help design applications ○ On deployment, the business data will have it’s own database ○ The “M” models could be used to create the application database structure  I could be wrong though...

26 Learning “M”  Oslo SDK Available for download  The “Oslo” Modelling Language Langworthy, Lovering, Box – Addison-Wesley  Learning MSchema will take a C# developer about a day

27 Quadrant Modelling Tool  Graphical tool used for managing instance models Targeted at architects and business analysts  Uses “Office Style” ribbon toolbar Everyone uses office  Loads model definitions from repository database Allows management of instances Changes are saved to database immediately

28 Oslo Architecture Repository MSchema Adds Structure Quadrant IDDataIdData 1Value 2Info

29 Quadrant Modelling Tool

30 Demo: Modelling in Quadrant  In this demo you will see: Using Quadrant to model a runtime environment Using Quadrant to design a service contract Quadrant workflow designer Publishing an application to the Dublin application server

31 Possible Future Oslo Scenario: Modelling a BizTalk Environment in Oslo  Design Use Quadrant to model production environment Groups, Servers, Hosts and Host Instances can be modelled Model is stored in repository database  Deployment Quadrant model can be used to create production environment Virtualization could make this easy  Note, this is just a possible scenario...

32 Oslo SDK  Available now msdn.microsoft.com/oslo  SDK Contains Repository database “M” modeling language (MSchema, MGrammar) IntelliPad editor  Does not include “Quadrant” Quadrant is available on the PDC08-CSD virtual PC image

33 “3 Dubs” – WCF/WF & Dublin  Windows Communication Foundation (WCF) Unified communications foundation  Windows Workflow Foundation (WF) Foundation for developing workflow based applications  Dublin Application server extensions for IIS7

34 Communication & Workflow Foundations  Windows Communication Foundation 4.0  Windows Workflow Foundation 4.0  Closely integrated in.net 4.0 “WCF/WF” can be considered as one technology  Extended use of eXtensible Application Markup Language (XAML).net VersionIntegration 3.0WCF | WF 3.5WCF + WF 4.0WCF/WF

35 eXtensible Application Markup Language (XAML)  Used in.net 3.0/3.5 WPF uses XAML to define user interfaces WF uses XAML to define Workflows  Use in.net 4.0 Extended support in WF Used in WCF for declarative services

36 Windows Communication Foundation  Unified communication framework  More than just SOA  Extensive functionality One to rule them all  Very extensible  Challenging to develop with “WCF is too complex for the average developer.” – Various sources

37 WCF 4.0  Services can be declared using XAML You can create a service with zero lines of code  Much tighter integration with WF  Tighter integration with Dublin application server  Improved REST support  Improved discovery support

38 Declarative Services  WCF Services can be declared entirely in XAML  Services are implemented using workflow designer  XAML can be stored as a file or in a database  No code required  No compilation required

39 Declarative Service Designer  Sequential Workflow designer used to model service implementation  Service is pure XAML

40 XAML Service Representation

41 Learn WCF!  “Om du inte har börjat titta på WCF eller XAML och WF då är jag rädd att säga att du är tvåa just nu.”  “Primärt WCF, absolut WCF, det finns ingen ursäkt kvar alls att ligga kvar på någonting annat än WCF just nu.” Johan Lindfors – Microsoft (MSDN Radio)  Resources Learning WCF: A Hands-on Guide – Michele Bustamente QuickLearn 3 day WCF Course - Hosted at Informator early 2009 Exam TS: “Microsoft.NET Framework 3.5 – Windows Communication Foundation Application Development”

42 Demo: Service Broker Implementation  In this demo you will see: Building standard WCF services Building declarative WCF services

43 Windows Workflow Foundation  Workflow foundation technology WF is a foundation, not a product  Used in Microsoft Server products Windows SharePoint Services 3.0 Microsoft Office SharePoint Server 2007 Microsoft Speech Server  Not used in BizTalk Server! Will not be used in BizTalk Server!  Used in 3 rd Party Products EpiServer K2.net Workflow

44 WF 4.0  Core WF class library has been re-written  Flowchart workflow model  10x – 100x performance increased  XAML has been greatly improved XAML is now default authoring mode  Designers have been re-written to use WPF 10x easier to add activity designers You may love it, you may hate it  Designer re-hosting is 10x easier

45 WF 3.5 vs. WF 4.0 Designers

46 Flowchart Workflow Model  Freeform workflow design model Activities can be placed anywhere  Less restrictive than Sequential model Flow can be routed between activities in workflow

47 Flowchart Workflow Model

48 Demo: WF 4.0 Designers  In this demo you will see: Creating a Sequential Workflow Creating a Flowchart Workflow

49 Dublin  Application Server Add in for IIS7 & WAS in Windows Server 2008 Will probably be free to license  Features Host for WCF 4.0 services Host for WF 4.0 workflows Basic service and workflow tracking (CTP version) Management tools hosted in IIS manager

50 Dublin Administration Tools  Built into IIS 7 Manager

51 Service and Workflow Configuration  Persistence Store SQL Server database for persisted instances Workflows and declarative workflow based services can persist  Throttling Maximum concurrent calls, instances and sessions can be configured  Tracking SQL Server database used for tracking Service and workflow execution can be tracked Options to track user data  Security Certificate configuration

52 Service and Workflow Configuration

53 Service and Workflow Management  Persisted workflow management Instances can be resumed or terminated  Application export and import Export from dev Import to test or production

54 Service and Workflow Management

55

56 Demo: Dublin Management Tools  In this demo you will see: Dublin configuration wizard Dublin management tools Dublin service configuration Viewing and managing service instances “DublinER” error reporting tool

57 Will {insert product} Replace BizTalk?  Windows Workflow Foundation Offers similar functionality to BizTalk Orchestrations Free to use Closer to.net than BizTalk Server Users can create custom activities  SQL Server Integration Services Features adapters and pipelines Very performant ETL processing Included in SQL 2005 licence  Dublin Application server hosting WCF/WF services Adds to functionality of IIS7 Will probably be free to use

58 BizTalk Strengths  Reliability Highly reliable messaging Highly reliable orchestration engine  Scalability Easily sailable to large environment  Management Tools Central management console for server group  Integration specific features More comprehensive range of adapters Strong EDI, Swift, HIPPA support BAM Trading partner management  Price Very competitive in integration space Standard edition for $8,499 (65,000 SEK)

59 BizTalk Server Weaknesses  Heavy ELT Data Integration BizTalk is more suited to many small messages than very large batches ETL can work in BizTalk, but performance is not optimal  Low-Latency SOA Solutions Multiple message box hops make latency an issue User interfaces scenarios are always an issue BizTalk can be tuned to reduce latency  Human Workflow Services Introduced in BizTalk Server 2004 Far too complex to justify implementation Even Microsoft BizTalk sales people said “Use something else for human workflow...”

60 Windows Workflow Foundation  Announced in 2005 “WWF will replace BizTalk Orchestration Engine” ○ Not true  Development History Included in.net 3.0 Improved in.net 3.5 Re-written in.net 4.0  Current usage Not gained traction amongst developers Re-write in.net 4.0 will affect 3.5 adoption Most used for human workflow scenarios in SharePoint projects

61 SQL Server Integration Services  Included in SQL Server 2005 Re-write of Data Transform Services (DTS)  Adapters & Pipelines FTP adapter SSIS Pipeline  Outperforms BizTalk for ETL operations Recommended to use instead of BizTalk Often used for ETL tasks in BizTalk projects

62 Dublin  Expected 2010 release No date confirmed “3 months after Visual Studio 2010” Free add-in for IIS7  Simple Functionality Basic management tools More challenging to scale Messages and processes not “highly reliable”  Low Latency Messages are not persisted in data store

63 Dublin vs. BizTalk BizTalkDublin $34,999 per proc ($8,499 Std Edn)Possible included in Windows Server 2008 License Hosts message channels and orchestrationsHosts services and workflows Uses message box for highly reliable messaging WS-RM can be used, messages not persisted Comprehensive range of receive endpoints (HTTP, TCP, File, FTP, MSMQ, MQSeries, POP3 etc.) Limited receive endpoints Fully supported for large scale deploymentsSome scalability is available Comprehensive management and diagnostics tools Basic management and diagnostics tools Tried and tested extensively in large scale deployments Currently “Pre-Alpha” Supports broad range of LOB applications (EDI, Swift, HIPPA) Not a supported scenario Latency can be an issue as messages are persisted Low latency achieved easily

64 Dublin Scenario  Portal application needs to provide users with low latency response from LOB system Low latency achieved  BizTalk Adapter Pack costs $5,000 Not much price difference with BizTalk Standard Edition MOSSDublinSAP HTTPSAP Adapter

65 Projects use more that one Technology  Human workflow based integration WF can be used in MOSS BizTalk can handle integration aspects  Integration with some ETL tasks SSIS used for ETL “heavy lifting” BizTalk used for messages based integration  SOA Based Integration BizTalk used where reliability is required Dublin used where low-latency is required
