Differences associees
Question 16. Explain the principles of the Twelve-Factor App in the context of microservices.
The Twelve-Factor App is a set of best practices for building scalable and maintainable web applications. In microservices, these factors guide the development and deployment of individual services.
Example:
One factor is 'Config,' emphasizing storing configurations in the environment to enable portability.
Question 17. What is the role of a API Gateway in handling security in microservices?
API Gateways can enforce security measures such as authentication, authorization, and encryption for incoming requests before they reach the microservices.
Example:
Implementing JWT-based authentication at the API Gateway level.
Question 18. Explain the concept of 'Chaos Engineering' in microservices.
Chaos Engineering is the practice of intentionally injecting failures and disruptions into a system to observe how it responds. This helps identify weaknesses and improve resilience.
Example:
Simulating a sudden increase in traffic to observe how microservices handle the load.
Question 19. How can microservices ensure data privacy and compliance with regulations like GDPR?
Microservices should implement proper data encryption, access controls, and auditing mechanisms to ensure data privacy. Compliance can be achieved through careful data handling practices.
Example:
Encrypting sensitive customer information in transit and at rest.
Question 20. What is the 'Saga Pattern' in microservices, and how does it address distributed transactions?
The Saga Pattern is a way to manage distributed transactions in a microservices architecture by breaking them into a series of smaller, more manageable transactions.
Example:
When placing an order, a saga may involve reserving the item, charging the customer, and updating the inventory in separate transactions.
