Sample Architecture: HTTP and SOAP Adapters

  • Makale

This topic describes the sample architecture when you use the HTTP and SOAP adapters to send and receive messages.

The following figure shows the components of the BizTalk Server sample architecture when you use the HTTP or SOAP adapters.

Figure 1 Sample architecture that shows HTTP or SOAP adapters

Sample architecture for HTTP or SOAP adapter

This sample architecture contains the components as discussed in the following sections.

Perimeter network―Internet

When you use the SOAP and HTTP adapters, we recommend that you use reverse proxy rules (the TMG Server implementation is called Web Publishing) to relay the message from the Internet-facing firewall (Firewall 1) to the firewall that helps protect the E-Business domain (Firewall 2), and from this firewall to the BizTalk Server that runs the isolated host. For more information about Web Publishing rules, see the Microsoft Web site at https://go.microsoft.com/fwlink/?LinkID=205340 (https://go.microsoft.com/fwlink/?LinkID=205340).

Note

When you use reverse proxy, you do not need Web servers in the perimeter network.

Perimeter network―intranet

Companies commonly use the HTTP and SOAP protocols for Internet-based communications, and therefore you do not need any servers in the intranet perimeter network to support this scenario. If you have an internal application in the intranet that integrates with BizTalk Server through the HTTP or SOAP protocols, you should follow the recommendations for the Internet perimeter network.

E-Business domain

This domain contains all the infrastructure and applications used by your BizTalk Server implementation. The servers in this domain are:

  • BizTalk Server (processing and tracking hosts). This server has an installation of the BizTalk Server runtime, and has instances of the hosts that contain the BizTalk orchestrations, pipelines, Business Rule Engine, and other business processes. This server also has a host instance of a host that supports tracking of health monitoring and business monitoring data.

    Note

    As your performance needs increase, you can add more BizTalk Servers to your environment for host instances of your processing hosts.

  • BizTalk Server (isolated hosts for SOAP and HTTP adapters). This server has an installation of the BizTalk Server runtime, and has only instances of the hosts that contain the HTTP and SOAP adapters. These hosts run in a separate server because these adapters require that you install Internet Information Services (IIS) on the computer where they run.

    Note

    As your performance needs increase, you can add more BizTalk Servers to your environment for host instances of your HTTP and SOAP adapter hosts. When you do this, you must also configure Network Load Balancing (NLB). For more information about how to configure BizTalk Server for high availability, see Planning for High Availability.
