Welcome! How to Use This Course Effectively1:09
What Is Coupling?3:02
To understand why microservices architecture can help with building flexible and scalable applications, we must understand the concept of Dependency in software engineering and its relevance to the microservices architecture.
Types of Coupling6:56
Two components or modules can be coupled in several ways. Some types of coupling are tighter than the other. We must understand these types of couplings so that in a real world problem we can do an educated trade off.
What is Cohesion?1:44
Practice Code for Coupling and Cohesion0:47

What are the differences between Monolithic, SOA and Microservices1:48
Benefits and Drawbacks of Monolithic Applications2:53
What are the alternatives of Monolith Applications?4:51
What are benefits of microservices architecture?4:44
What are the drawbacks of microservices?2:49

Explain Testing Strategies in Microservices1:49
What is Mike Cohn’s Test Pyramid?1:33
What is Semantic Monitoring?2:13
Explain continuous monitoring2:00
Explain the Role of Observability in Microservices2:55
Observability is a critical part of a microservices ecosystem. It gives us a clear view about the health of the infrastructure, individual microservices, and the system as a whole. Without an effective observability system, identifying system bottlenecks, errors and performance issues is difficult if not impossible.

Description

Excel in your next job interview by mastering this course's expertly curated microservices interview questions and answers.

Learning the complex microservices architecture concepts and design patterns can take considerable time. You will need these guided interview questions for two main reasons: first, to assess your learning outcomes after studying microservices architecture, and second, to learn through a question-and-answer technique, which yields similar results in a much shorter time.

Whether you want to check your readiness for job interviews or speed up your learning process, this course is tailor-made to help you deeply understand Microservices Architecture's core concepts, architectural patterns, and techniques.

With 50 meticulously curated questions and detailed explanations, you'll swiftly grasp essential architectural patterns, ensuring you're well-prepared for any interview scenario. When answering each interview question, more than one option is often mentioned, and comparisons between options are made to help the students understand what pattern is best for a given context and what the trade-offs are.

Whether you're proficient in Java, Python, C#, or any other programming language, this course caters to all developers, irrespective of their tech stack preferences. However, it notably excludes specific frameworks like Spring Boot.

Topics covered include:

Microservices Design & Architectural Patterns
Events vs. Messages vs. APIs
Microservices Examples
Microservices on AWS, Azure, and Google Cloud Platforms
Containers and Docker
Monolith-to-Microservices Transformation
Integration Patterns, i.e., API Gateways.
Cloud-Native Microservices
Monitoring Strategies

As you progress through the course, you'll have the opportunity to gauge your readiness with a quizes and mock AI interviews (Role Plays), which will empower you to approach even the most daunting job interviews confidently.

Whether you aspire to become a seasoned software architect, ace technical interviews, or deepen your microservices expertise, enroll today and embark on your journey towards success!
