ARCHITECTURE
PROCESSING ENGINE
Enables complex task management
Package of micro-services executing flows of tasks in a variety of platforms
Each flow can be fully configured, allowing sequential or parallel tasks
Features three main classes of components:
RECEPTOR
- Main entry point of any request
- Capability to perform technical validations
- Provides several services (endpoints) to be invoked based on user configuration
ORCHESTRATOR
- Oversees the control of the flow of tasks
- Tracks the evolution of each task
- Message-enabled communication between components
EXECUTOR
- Responsible for the actual running of the work tasks
- Self-scaling within its available resources
- Each component is dedicated to a work domain dependent on customer requirements and constraints
PAYMENTS is packaged as a set of micro-services, each responsible for a certain domain of actions
Allows new components to be added or old ones removed without jeopardizing its consistency
New micro-services can be incorporated without disrupting the existing platform
Customers can grow and adapt without fearing loss of service
