Question
Which of the following best describes 'microservices architecture'?
Solution
Microservices decompose applications into loosely coupled services (e.g., separate services for authentication, account management, payments, notifications), each with its own database, deployable independently, and communicating via APIs or message queues (Kafka, RabbitMQ). Benefits: independent scaling, technology flexibility, fault isolation, faster deployment. Many large banks (HDFC, SBI) are migrating from monolithic core banking systems to microservices for digital agility.
