Deployment Options

Use

Depending on your preferred system landscape, different deployment options are available for SAP Gateway:

  • Central Hub Deployment (service development in the SAP Business Suite backend system)

  • Central Hub Deployment (service development in SAP Gateway hub system)

  • Embedded Deployment (service development in the SAP Business Suite system)

The following graphic provides a simplified overview of the different deployment options available to you.

Central Hub Deployment

Central hub deployment of SAP Gateway has the following advantages:

  • Routing and composition of multiple systems is supported.

  • Dedicated SAP Gateway content is available.

  • Content can be deployed without touching the SAP Business Suite system.

  • Decoupled lifecycle of consumer applications from the SAP Business Suite system.

  • Central management of routing and connectivity with SAP Business Suite systems.

  • SAP Gateway capabilities need to be deployed only once within the landscape.

  • Better security, as a request is validated at the dedicated box and consequently attacks on the SAP Gateway system will not automatically affect the SAP Business Suite system.

  • A separate SAP Gateway system can be implemented in a demilitarized zone (DMZ) for external access.

  • Independent innovation speed of SAP Gateway and the connected SAP Business Suite systems.

  • Development of context specific to SAP Business Suite system within the SAP Business Suite system enables you to reuse data stored in the SAP Business Suite system easily since development takes place in the system in which your data is stored. This development is bound to the lifecycle of the SAP Business Suite system.

However, note that there will be a redundant deployment of metadata or ABAP Dictionary structures. If you want to use the Screen Scraping generator, you must install the component IW_SCS in the SAP Business Suite system.

The following diagram shows an example of central hub deployment in a standalone system based on SAP NetWeaver 7.4.

Embedded Deployment

Deployment embedded in the SAP Business Suite system has the following advantages:

  • Direct local access to metadata and business data, meaning easy reuse of data.

  • Less runtime overhead as one remote call is reduced.

  • No content merge for different applications required.

  • No additional, separate SAP Gateway system required.

  • Lower total cost of ownership as there is one less system to maintain.

However, note the following considerations:

  • The innovation speed of SAP Gateway and the SAP Business Suite system need to be synchronized.

  • Devices need to be integrated with the SAP Business Suite system on a point-to-point basis.

  • Cross-system composition is not advisable.

  • Central SAP Gateway content is not available. Content specific to SAP Business Suite is used in SAP Business Suite system.

The following diagram show an example of embedded deployment in an SAP Business Suite system based on SAP NetWeaver 7.4.
