In this course, you’ll learn everything you need to know to confidently tackle any microservices-related questions that come your way in your next interview. With 250+ questions and advanced explanations, we’ll cover key concepts, principles, and design patterns, as well as common pitfalls and best practices of microservices architectures. Over the years, software development moved away from traditional monolithic architectures, because of the complexities with tightly coupled, interconnected code. As a result, microservices are adopted many projects in many enterprise companieswith using cloud-native approaches that enable distributed computing through multiple smaller services. And Microservices Architecture knowledge is key crucial skill that companies are demanding critically. With this course, you’ll test and learn about Microservices Interview Questions (250+) with topics listed below: Microservices DecompositionMicroservices Communications (Sync / Async Message-Based Communication, API Gateways)Microservices Data Management (Databases / Query / Commands / Distributed Transactions)Microservices Distributed TransactionsMicroservices Deployments with Containers and OrchestratorsMicroservices ResiliencePatterns & Best Practices that we will cover during the course: API Gateway Pattern, Gateway Routing Pattern, Gateway Aggregation Pattern, Gateway Offloading Pattern, Backends for Frontends Pattern-BFF, Service Aggregator Pattern, Service Registry/Discovery PatternSingle-receiver Message-based Communication (one-to-one model), Multiple-receiver Message-based Communication (one-to-many model-topic), Fan-Out Publish/Subscribe Messaging Pattern, Topic-Queue Chaining & Load Balancing PatternThe Shared Database Anti-pattern, Relational and NoSQL Databases, CAP TheoremConsistency, Availability, Partition Tolerance, Data Partitioning: Horizontal, Vertical and Functional Data Partitioning, Database Sharding PatternMaterialized View Pattern, CQRS Design Pattern, Event Sourcing Pattern, Eventual Consistency PrincipleSidecar pattern, Service Mesh, Infrastructure as code (IaC), CI/CD pipelinesRetry pattern, Circuit Breaker Pattern, Bulkhead Pattern, Fallback Pattern, Strangler Fig PatternAnd you’ll learn how to discuss these topics in the context of real-world scenarios. We’ll cover common interview questions. Sample Questions: What does “design for failure” mean in a Microservices Architecture?

Why is the Shared Database principle considered an anti-pattern for microservices? Which type of database is best suited for a microservice that handles orders and transactions in an e-commerce system? How can the CAP theorem be applied in the design and implementation of microservices? How is database sharding pattern used to improve the performance and scalability of databases in microservices? When should the materialized view pattern be used in microservices? How can read and write databases be kept in sync in a CQRS architecture? Which of the following can be real-world use cases of microservices that use CQRS and Event Sourcing? How does distributed caching improve the performance of a system that uses microservices? What is the main disadvantage of cache miss in a distributed caching system for microservices? What is the advantage of using the saga pattern for implementing distributed transactions in microservices architecture? Which is the example of a real-world scenario where the saga pattern could be used in a microservices architecture?In a choreography-based saga, who is responsible for coordinating the updates to the databases? What is the key responsibility of the central orchestrator service in an orchestration-based saga implementation? How can CDC and the transactional outbox pattern be used together in a microservice architecture? What is the role of service meshes in the communic
