Welcome to Apache Agila Wiki

Agila is centered around Business Process Management, Workflow and Web Service Orchestration. It's composed of two specialized modules: Agila BPM and Agila BPEL.

Agila BPM is basically handling tasks and users who have to complete these tasks. It's a very flexible and lightweight workflow component.

Agila BPEL is a BPEL-compliant Web Services Orchestration solution. Here is a short description of what BPEL is good and bad for (from Paul Brown's presentation "BPEL for Programmers and Architects")

  • BPEL is not workflow: there are no explicit abstractions for people, roles, work items, or inboxes in BPEL (among other things).
  • BPEL is also not BPM: no specified data model for measurement, reporting, or management.
  • BPEL is not integration: there is no explicit support for transformation, semantic interpolation, or specific protocols.
  • BPEL is not all-encompassing: there are some patterns that are difficult to model with BPEL.
  • BPEL (i.e., an implementation) abstracts the common, non-process-level concerns of business process execution.
  • As a service-tier composition language, BPEL is a key ingredient in a service-oriented architecture.
  • BPEL provides a deployment-level interface for higher-level tools (e.g., modeling).
  • "Low-hanging" innovation does not create sustainable competitive advantage.
  • Complexity will remain an unavoidable part of the enterprise technology landscape. Managing and minimizing that complexity will create leaders.
  • Defining the organizational processes around BPEL, i.e., who uses BPEL and how, is of paramount importance to the role and success of service oriented architecture.
