Bounded context concept in Microservices - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a bounded context in microservices.

Microservices

class [1]Context:
    def __init__(self):
        self.services = []

Drag options to blanks, or click blank then click option'

BPayment

CInventory

💡 Hint

Common Mistakes

Choosing a generic term like Database which is not a bounded context.

The User context represents a bounded context focusing on user-related services.

2fill in blank

medium

Complete the code to show communication between two bounded contexts.

Microservices

def communicate(context_a, context_b):
    return context_a.send_message_to([1])

Drag options to blanks, or click blank then click option'

Acontext_b

Bnetwork

Cdatabase

Dcontext_a

💡 Hint

Common Mistakes

Using context_a which is the sender itself.

Bounded contexts communicate directly with each other, so context_b is the correct target.

3fill in blank

hard

Fix the error in the code to correctly isolate bounded contexts.

Microservices

class OrderContext:
    def __init__(self):
        self.data = [1]

    def add_order(self, order):
        self.data.append(order)

Drag options to blanks, or click blank then click option'

CNone

D[]

💡 Hint

Common Mistakes

Using {} which is a dictionary and does not support append.

The data should be a list [] to append orders properly.

4fill in blank

hard

Fill both blanks to define two bounded contexts with clear separation.

Microservices

class [1]Context:
    pass

class [2]Context:
    pass

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing the same context name twice.

User and Order are two distinct bounded contexts representing different business domains.

5fill in blank

hard

Fill all three blanks to complete the microservice architecture with bounded contexts.

Microservices

services = {
    '[1]': ['AuthService', 'ProfileService'],
    '[2]': ['OrderService', '[3]']
}

Drag options to blanks, or click blank then click option'

BPaymentService

COrderContext

💡 Hint

Common Mistakes

Mixing service names with context names.

The UserContext contains user-related services, OrderContext contains order-related services including PaymentService.
