Use this section to learn about the overall architecture of BMC Remedy AR System and understand the conceptual overview of the components in BMC Remedy AR System.

BMC Remedy AR System is based on a multitiered client/server architecture that includes the client tier, the mid tier, the server tier, and the data tier. The following figure shows the different tiers of BMC Remedy AR System.

  • Client tier — Contains AR System clients. Most clients present information to application users and receive input from them, but the tools for migration and application development are also clients.
  • Mid tier — Contains components and add-in services that run on a web server, enabling users to view applications on the web.
  • Server tier — Contains the BMC Remedy AR System server, which controls workflow processes and access to databases and other data sources in the data tier. This tier also contains server-side applications (such as Approval Server, Email Engine, and the BMC Remedy Flashboards server) and the C and Oracle Java plug-in servers with plug-ins.
  • Data tier — Contains database servers and other data sources that can be accessed by the BMC Remedy AR System server. The database server acts as the data storage and retrieval engine.

AR System clients provide the user interface. The BMC Remedy Mid Tier makes the user interface available in browsers. The AR System server implements the workflow functions, access control, and flow of data into and out of the database. The database server acts as a data storage and retrieval engine. (For information about supported platforms, see Compatibility matrix in the BMC Remedy ITSM Deployment online documentation.)
