Business Process Execution Language (BPEL) is an XML-based language for modeling and executing orchestrated web-service processes. It defines control flow, data mappings and fault handling between services. BPEL is used for service-oriented integration to specify automated, repeatable business processes and requires architecture decisions about transactions,…

BPEL is an XML-based language for defining and executing orchestrated web-service processes.
BPEL emerged from the need to describe long-running web-service interactions as executable process logic rather than as loose interface contracts. Its roots lie in IBM WSFL and Microsoft XLANG; in 2001/2003 related approaches were combined as BPEL4WS before OASIS standardized the language as WS-BPEL and published version 2.0 in 2007. It addresses "programming in the large" for service-oriented workflows.
Think of BPEL as an execution director for services. A process connects partner links to services, stores data in variables, and runs activities such as receive, invoke, assign, if, while, or flow in a defined order. Correlation tells the engine which instance a message belongs to; faults and compensation describe how the process ends cleanly or partially rolls back when something fails.
The process logic centrally directs service calls and coordinates multiple parties into one flow.
Partner links connect the process with external services and name the roles used in the exchange.
Building blocks such as receive, invoke, reply, assign, sequence, flow, if, and while shape the executable process.
Messages are routed to the correct running process instance even when many instances exist at once.
Error paths and compensation actions define how the process handles failures and undoes partial work.
Executable processes are run by an engine; abstract processes describe observable behavior without full implementation details.
BPEL is useful when multiple services must be coordinated into a repeatable, centrally controlled business process, especially in service-oriented integration. The trade-off is added complexity around transaction boundaries, state management, interoperability, and governance. Without stable interfaces and clear error or compensation rules, the model becomes hard to maintain.
