Description: NServiceBus is an enterprise service bus (ESB) that supports workflows and integrations in .NET. This technology uses event-driven and standards-based message-oriented middleware, provides publish and subscribe functionality, handles message queues, and provides remote procedure call capabilities. NServiceBus provides a generic host similar to generic application servers on the Java platform. The NServiceBus Host provides standardized installation and manageability as well as providing a lightweight sandbox where all infrastructure components automatically switch to in-memory mode.

NServiceBus may be built from source code or may be ran within the Particular Service Platform. The source code is provided via open source licensing and may be built with Microsoft Visual Studio. To run this technology within the Particular Service Platform, users must first purchase a license for the platform. When configured with the Particular Service Platform, there is a free trial option as well as the option to deploy NServiceBus on-premise, in the cloud, or as a hybrid solution.

This technology uses a Microsoft SQL Server database to store data.

The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g. VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e. SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at: https://dvagov.sharepoint.com/sites/OITEPMOECSO
