Complete the code to define a microservice based on business capability.
class [1]Service: def __init__(self): pass def execute(self): print("Executing business logic")
The microservice should be named after a business capability, such as 'Order'.
Complete the code to implement a microservice that communicates asynchronously using {{BLANK_1}}.
def send_event(event): [1].publish(event) send_event({'type': 'OrderCreated'})
Message queues are used for asynchronous communication between microservices.
Fix the error in the code to correctly implement database per service pattern with {{BLANK_1}} isolation.
class PaymentService: def __init__(self): self.db = [1]('payment_db') def save_payment(self, payment): self.db.insert(payment)
Each microservice should have its own dedicated database to ensure loose coupling and data isolation.
Fill both blanks to implement API Gateway pattern with {{BLANK_1}} routing and {{BLANK_2}} aggregation.
class APIGateway: def route_request(self, path): if path == '/orders': return self.[1]('OrderService') def aggregate_responses(self, responses): return [2](responses)
API Gateway routes requests by forwarding them and aggregates responses by combining them.
Fill all three blanks to implement event-driven communication with {{BLANK_1}} publishing, {{BLANK_2}} subscribing, and {{BLANK_3}} processing.
class InventoryService: def publish_event(self, event): [1].send(event) def subscribe_events(self): [2].listen(self.process_event) def process_event(self, event): [3].process(event)
EventBus is used to publish events, EventListener subscribes to events, and Callback processes them.
