  • Hi Vivek, it's hard to say something without know some details of your infrastructure. But before run some performance or diagnosis tool, I suggest that you ready carefully this article and check every detail:

    http://msdn.microsoft.com/en-us/library/hh397322.aspx

    About your question, all services in AX2012 are processed at AOS, that hosts the WCF endpoints. For external users connecting to ports through HTTP/web-services, IIS just send the requests to AOS process via WCF routing service.

    So, we have two key points to start: if your NLB are configured properly and if your servers (AOS/SQL) are sized enough to deal with this number of parallel users.

    Cheers.

  • Hi Fabio,

    Nice article explaining the WCF services support in Dynamics AX, but can you help me understand one particular scenario. In my project I have 4 front end servers hosting Sharepoint 2010 customer website and 2 servers for DAX 2012, all the servers are in NLB, and the WCF services are hosted in AOS (using net.tcp adapter), but the performance is really killing us as the websites are not supporting even 100 users parallely, so should we host WCF in IIS or continue hosting it on AOS directly?

  • 2. Services Overview Lesson 1: Service Groups Lesson 2: Ports and Adapters Lesson 3: Infra & Deployment Lesson 4: Custom Services Lesson 5: Consuming Web Services Lesson 6: Transformations Lesson 7: Office Add-in
  • 3. Overview  In Microsoft Dynamics AX 2012, the Application Integration Framework (AIF) underwent a number of dramatic changes, starting with its name. The AIF is now known as Services. In the application you will see it listed as Services and Application Integration Framework.  In Microsoft Dynamics AX 2012, the module offers more options for WCF service hosts, a reduction in the number of forms and concepts, an increase in the performance of service calls and more flexibility in the classes on which services can be built.
  • 4. Lesson 1: Service GroupsThis lesson defines the term Service Group and describes what it contains What is and advantages  Service Groups is a new node added to the AOT and they are hosted on the AOS.  A single service group consists of a set of services deployed together.  Besides having services consistently managed and deployed together, there are other advantages to service groups:  All the services are contained within the same WSDL;  You only need to add one service reference in Microsoft Visual Studio to access all of the objects from the services in the service group;  You can use the types exposed in the services throughout your .NET code.
  • 5. Lesson 2: Ports and AdaptersThis lesson defines the terms Basic and Enhanced Ports and Adapter types Introduction  A port represents a Windows Communication Foundation (WCF) service host, and all services that it hosts are WCF endpoints. By default, a port is hosted on the Application Object Server (AOS) or on Internet Information Services (IIS) if HTTP is chosen as the adapter.  In Microsoft Dynamics AX 2009, the configuration of AIF involved several concepts including local endpoints, adapters, channels and endpoints. Each concept had multiple steps and its own form. In Microsoft Dynamics AX 2012, the user interface for the Services module is dramatically restructured resulting in the introduction of ports and most of the concepts are generated for you and they are configured in a single form.
  • 6. Lesson 2: Ports and AdaptersThis lesson defines the terms Basic and Enhanced Ports and Adapter types Types  There are both Inbound and Outbound ports that have similar functionality. Inbound ports handle incoming requests. Outbound ports handle requests that are outbound only, such as when the Send electronically is clicked on a form within the application.  Inbound ports can be Basic or Enhanced. When a service group is deployed, basic ports are generated and configured automatically. Enhanced ports are port you create manually. They give you several options around hosting, adapter types, document processing, error handling and security.
  • 7. Lesson 2: Ports and AdaptersThis lesson defines the terms Basic and Enhanced Ports and Adapter types Basic Port  After a service group is deployed, a basic port is generated to represent the service group. The port will have the same name as the service group it represents, is deployed as a WCF service hosted on your AOS instances and you call these services using the NetTcp adapter.
  • 8. Lesson 2: Ports and AdaptersThis lesson defines the terms Basic and Enhanced Ports and Adapter types Enhanced Ports  Enhanced ports allow many more configuration options than are possible with a basic port. For example, basic ports are deployed as WCF services only to the AOS and use the NetTcp adapter. With an enhanced port, you can choose between an AOS or an IIS host and have several choices for adapter types.  The options for adapters type are: File System, HTTP, MSMQ and NetTcp  Services in Microsoft Dynamics AX 2012 are hosted on the AOS by default, but can also be hosted on IIS. To consume services over the Internet, you must use the HTTP Adapter and host services on IIS. IIS routes all service requests to the AOS. Regardless of the origin of the service request, Internet or Intranet, all the service requests are processed on the AOS.

  • 10. Lesson 3: Infra & DeploymentThis lesson describes the changes in infrastructure and deployment Performance and Scalability Improvements  The limitations around file sizes (10 MB) no longer exist;  X++ services classes compile into CIL;  Intranet deployment does not require IIS, services are hosted on the AOS by default;  .NET Business Connector is not used by services hosted on the AOS and in IIS;  Session pooling is used to reduce the overhead on operation calls.
  • 11. Lesson 3: Infra & DeploymentThis lesson describes the changes in infrastructure and deployment Services Hosted and Deployed on the AOS There are a some steps for the service to be exposed on the AOS:  A new .NET service assembly is built and copied to the Microsoft Dynamics AX application share.  If re-deploying, the previous service host on the AOS is stopped and the old service assembly is unloaded.  A new service host is created/instantiated on the AOS instance.  When the AOS starts, the AOS startup code loads the new service assembly from the application share.  A new service assembly generated is hosted only in the current AOS, other AOS instances pick up only at startup time.
  • 12. Lesson 3: Infra & DeploymentThis lesson describes the changes in infrastructure and deployment Services Hosted and Deployed in IIS Changes in hosting services on IIS for requests originating from the Internet:  In MS DAX 2009, IIS hosted services used the .NET Business Connector (BC) to communicate with the AOS.  In MS DAX 2012, IIS hosted services use the WCF routing service to send service requests to the AOS.  The WCF routing service does use the Business connector proxy account only to pass the calling users context to the AOS.  All service requests, regardless of their origin, are processed on the AOS.
  • 13. Lesson 4 - Custom ServicesThis lesson describes changes to create custom document services Custom Document Services The steps for creating and updating custom document services are the same as they were in DAX 2009. A difference in the process in DAX 2012, is where you implement your defaulting code. In all previous versions of DAX, defaulting logic for services was implemented in AxBC classes like AxSalesTable or AxSalesLine. The same logic for interactive scenarios was repeated in locations that could not be used by services like the methods on forms. In Microsoft Dynamics AX 2012, in order to avoid duplicating logic, defaulting code can be put on the table in the defaultField() method.
  • 14. Lesson 4 - Custom ServicesThis lesson describes changes to create custom document services Custom Document Services Example of defaultField() usage:
  • 15. Lesson 4 - Custom ServicesThis lesson describes changes to create custom document services Custom Document Services Changes in creating the query used by custom document services:  It is not necessary to include tables for foreign key references in your query. The document services framework will provide foreign key substitution.  If the tables in your service include dimension key values, it is not necessary to include the dimension framework tables in your query.
  • 16. Lesson 4 - Custom ServicesThis lesson describes changes to create custom document services Custom Services As in previous versions of Microsoft Dynamics AX, non-document custom services can be created. In Dynamics AX 2012, the process for creating a non-document service class is easier because classes can be decorated as DataContract classes. The use of non-document classes is more common in 2012.
  • 17. Lesson 4 - Custom ServicesThis lesson describes changes to create custom document services Data and Service Contract Classes A data contract can be either an X++ or a .NET class that has getters, setters and the DataContractAttribute attribute. Example:
  • 18. Lesson 4 - Custom ServicesThis lesson describes changes to create custom document services Data and Service Contract Classes After you have created a data contract class, you create the service contract class. The service contract class is the class that is exposed as a service. It consumes the data contract class. Example:
  • 19. Lesson 5: Consuming Web ServicesThis lesson describes the improvements in consuming web services 2012 vs 2009 In DAX 2009, you could consume an external web service from X++ code by adding a Service reference under the References node of the AOT. The issue with this functionality was that the service references ran in a separate application domain compared to the X++ code. In DAX 2012, this was replaced by a new model for consuming external Web service, where you can add your Visual Studio projects into AOT. In Visual Studio, with a reference to the same web service and an instance of the same proxy class, Intellisense displays many more properties and methods.
  • 20. Lesson 6: TransformationsThis lesson shows the improvements in transformation of incoming data Improvements In DAX 2009, you were able to transform incoming data through the use of pipeline components. The application shipped with two pipeline components:  Value substitution: allow users to substitute an incoming value with a destination value.  XSLT transformation: allowed users to create XSLT transformations that converted an inbound document format to the required schema of the DAX document. In order to implement any other transformations you were required to create a custom pipeline component class. We are still able to use value substitution and xslt transformations similar to that implemented in DAX 2009. In addition, DAX 2012 now allows you to implement custom transformation assemblies using the .Net and Visual Studio 2010.
  • 21. Lesson 7: Office Add-inThis lesson shows how to use Office with Dynamics AX Word & Excel The Office Add-ins for Microsoft Dynamics AX 2012 enable queries and AIF Document services to be integrated into Excel or Word. Only services that have Create or Update methods can be used as data sources to modify data in excel. In order to use the services, you must first add them to an AIF Services port and activate the port. To use a service or query within Microsoft Excel or Word, you must expose these services and queries as a data source.
