New Course ! Microservices Interview: Essential Questions and Answers

I have just published a new course — Microservices Interview: Essential Questions and Answers.

This is a practical test that will Ace Your Next Microservices Interview with essential interview questions that are more than 250+ questions, including design patterns and best practices.

Microservices are adopted many projects in many enterprise companies with using cloud-native approaches and Microservices Architecture knowledge is key crucial skill that companies are demanding critically.

For that reason, I have prepared this course to Prepare for Software Architecture Interviews that demanding Microservices Skills.

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.

In this course, We have 6 different practical tests about Microservices Vertical Considerations:

Microservices Fundamentals and Decomposition
Microservices Communications (Sync / Async Message-Based Communication, API Gateways)
Microservices Data Management (Databases / Query / Commands / Distributed Transactions)
Microservices Distributed Transactions
Microservices Deployments with Containers and Orchestrators
Microservices Resilience and Advanced Topics like Microservices Security, Testing

This course will be 100% microservices interview questions, and you’ll test and learn about Microservices Interview Questions (250+) with advanced explanations.

Course Details

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 companies with 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.

For that reason, I have prepared this course to Prepare for Software Architecture Interviews that demanding Microservices Skills.

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.

In this course, We have 6 different practical tests about Microservices Vertical Considerations:

Microservices Fundamentals and Decomposition
Microservices Communications (Sync / Async Message-Based Communication, API Gateways)
Microservices Data Management (Databases / Query / Commands / Distributed Transactions)
Microservices Distributed Transactions
Microservices Deployments with Containers and Orchestrators
Microservices Resilience and Advanced Topics like Microservices Security, Testing

This course will be 100% microservices interview questions, and you’ll test and learn about Microservices Interview Questions (250+) with advanced explanations.

Patterns & Best Practices for Microservices Interviews

Let me write some microservices pattern which we covered in this courses;

Microservices Sync Communication Patterns

API Gateway Pattern, Gateway Routing Pattern, Gateway Aggregation Pattern, Gateway Offloading Pattern, Backends for Frontends Pattern-BFF, Service Aggregator Pattern, Service Registry/Discovery Pattern.

Microservices Async Communication Patterns

Single-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 Pattern.

Microservices Data Management Patterns — Choosing Database

The Shared Database Anti-pattern, Relational and NoSQL Databases, CAP Theorem–Consistency, Availability, Partition Tolerance, Data Partitioning: Horizontal, Vertical and Functional Data Partitioning, Database Sharding Pattern.

Microservices Data Management Patterns— Commands & Queries

Materialized View Pattern, CQRS Design Pattern, Event Sourcing Pattern, Eventual Consistency Principle.

Microservices Distributed Transactions Patterns

The Saga Pattern, Choreography-based SAGA, Orchestration-based SAGA, Compensating Transaction Pattern, Dual write problem, Transactional Outbox Pattern, CDC — Change Data Capture.

Microservices Deployments Patterns

Containers and Orchestrators, Kubernetes Patterns, KEDA — Kubernetes Event-driven Autoscaler, Sidecar pattern, Service Mesh, Infrastructure as code (IaC), CI/CD pipelines.

Microservices Resilience Patterns

Microservices Observability Patterns (distributed logging, health monitoring, distributed tracing), Resilience Patterns; Retry pattern, Circuit Breaker Pattern, Bulkhead Pattern, Fallback Pattern.

Microservices Modernization Patterns

Strangler Fig Pattern.

Also we will cover other advanced topics like Microservices Testing Patterns and Microservices Security Patterns.

Example of Microservices Data Management — Main Topics

Here you can see that, we can divide by 3 for Microservices Data Management Topics:

You can see the parts and related patterns that we will cover during the Practical Test for Microservices Data Managements.

Sample Questions of this Practical Test

Here you can find the Sample Questions of this Practical Test that you can face these question during the course and you will get very detailed extensive answers for every questions.

How to maximize benefit of this practical test ?

In order to maximize benefit of this course, After taking this practical test, you should read all answers of every questions even you replied correctly. Because every question has extensive detailed explanations that you can learn all aspects of that topics. Here you can see example question:

Here you can find Example Answer for above question:

As you can see that answers are includes extensive explanation of topics and related topics for microservices. So to understand every topics, I high recommended to check all detailed answer after taking all practical tests.

Conclusion

By the end of this course, you’ll have a deep understanding of microservices and the ability to articulate their benefits, drawbacks. Also, you’ll gain the confidence and skills to hack your next software architecture microservices interview and take your career to the next level.

By practicing with this test, You will learn how to demonstrate your knowledge and expertise in microservices with real-world experience and projects, and create strategy for how to effectively communicate and collaborate with the interviewers.

I hope you’ll join me on this journey.
