Business Central Component and System Topology
The Business Central deployment includes three core components for serving the application to users. It also includes various tools and components for managing, developing, extending, and testing the application.
Multi-Tier System Topology
To understand the components is useful to first look at the base topology of a Business Central deployment, as illustrated in the following diagram:
Components
Main components
Every deployment must include the core components: Web server, Server, and SQL Database.
| Component | Description | More Information |
|---|---|---|
| SQL Database | A SQL database (SQL Server, SQL Server on Azure VM, Azure SQL Managed Instance, or Azure SQL Database) that contains application object definitions and business data. In a multitenant deployment, the application and business data are separated into different databases. In this case, a single application database can be associated with one or more tenants where the tenant database contains the business data. | Creating Databases Deploy a Business Central Database to Azure SQL Database |
| Server | Business Central Server is a .NET-based Microsoft service application that uses Windows Communication Framework to handle communication between clients and databases. It controls authentication, event logging, scheduled tasks, reporting, and more. | Configuring Business Central Server |
| Web Server | An Internet Information Server (IIS) web site, provisioned with the Business Central Web Server components, that enables access from the Business Central Web client and mobile apps. | Business Central Web Server |
| Business Central App | A desktop, phone, and tablet app for Business Central. | Get the Mobile App Get the Desktop App |
| Web services | SOAP and OData Web Services for exposing application functionality to external systems and users. Developers can create and publish functionality as web services. They expose pages, codeunits, or queries, and even enhance a page web service by using an extension codeunit. | Web Services |
