An XML-based language called BPEL (Business Process Execution Language) enables web services, APIs, and human procedures in a service-oriented architecture (SOA) to communicate with one another and share data in a business workflow.
Orchestration versus Choreography
Web services can be combined in two ways:
A central process (which could be another Web service) takes control of the associated Web services in orchestration, which is typically used in private business processes, and organises the execution of various activities on the Web services engaged in the operation.
In contrast, there is no single coordinator for choreography. Instead, every Web service taking part in the choreography is aware of exactly when to carry out its actions and who to engage with.
In the past, many companies developed and operated business operations using a single, enormous monolithic program. These would frequently deteriorate and be challenging to maintain.
Many firms are now increasingly handling business tasks using smaller web services or microservices in response to these difficulties. To enable various services to collaborate and work towards a single objective, BPEL serves as the binding agent or the common language.
