Part 4 Interview Questions on Monitoring & Logging and Deployment & DevOps related topics in Micros

Hello everyone! Welcome back to CodeAdmirer! In today’s session, we’ll explore microservices related interview questions on Monitoring & Logging and Deployment & DevOps related topics. If you have a specific topic related to interview questions that you’d like us to cover, please let us know in the comments! Let’s get started! 61-70: Monitoring & Logging 61. How do you implement logging in ASP.NET Core? Use the built-in logging framework, configuring different logging providers such as Console, Debug, and third-party logging frameworks like Serilog. 62. What is distributed tracing in microservices? A method for monitoring applications, capturing the flow of requests through various services and tracking performance bottlenecks. 63. How can you monitor the health of microservices? Implement health checks using the `HealthChecks` API in ASP.NET Core, allowing you to query the health status of your services. 64. What are the best practices for logging in microservices? Maintain a consistent logging format, use structured logging, and centralize logs for easier management. 65. What is Application Insights? A Microsoft Azure service that provides application performance management and monitoring capabilities, offering telemetry data for diagnosing issues. 66. How can you implement metrics collection in microservices? Utilize libraries like Prometheus or Grafana to collect and aggregate metrics, providing insights into service performance. 67. What is a logging aggregation tool? A tool that consolidates logs from multiple services into a central system for analysis. Examples include ELK Stack (Elasticsearch, Logstash, Kibana) and Splunk. 68. How do you alert on specific events or errors in microservices? Set up monitoring alerts based on log data or metrics collected by monitoring tools. 69. What is Serilog and how is it used? Serilog is a structured logging library for .NET applications that supports various output sinks and is often used for its rich logging capabilities. 70. What is sidecar proxy? A sidecar proxy is a pattern where a proxy service runs alongside a microservice to handle communication, security, and monitoring. 71-80: Deployment & DevOps 71. How do you deploy microservices in Docker? By creating a Dockerfile for each microservice, defining the application environment, and using Docker Compose or Kubernetes for orchestration. 72. What is Kubernetes? Kubernetes is an open-source container orchestration platform that automates deploying, scaling, and managing containerized applications. 73. How do you implement CI/CD for microservices? By setting up a CI/CD pipeline using tools like Azure DevOps, Jenkins, or GitHub Actions, enabling automated builds, tests, and deployments for microservices. 74. What is a service mesh, and why is it useful? A service mesh is an infrastructure layer that manages service-to-service communication, providing features like traffic management, resilience, and security. 75. What are Helm charts? Helm charts are packages for Kubernetes applications, allowing developers to define, install, and manage applications running on Kubernetes clusters. 76. How do you perform blue-green deployments? Blue-green deployment involves having two identical production environments (blue and green) and switching traffic between them during deployments to minimize downtime. 77. What is canary deployment? Canary deployment is a technique where a new version of an application is rolled out to a small subset of users before a full deployment, allowing for testing in a live environment. 78. What are the benefits of using containers for microservices? Containers provide consistency across environments, isolation, quick startup times, and resource efficiency, making them ideal for microservices architecture. 79. How can you implement health checks in Kubernetes? By defining liveness and readiness probes in the pod specification, ensuring that Kubernetes can detect and manage the health of applications effectively. 80. What is the 12-Factor App methodology? A set of best practices for building modern, scalable web applications, focusing on principles like codebase management, dependency isolation, and continuous deployment. 81-90: Best Practices & Design Patterns 81. What is the Circuit Breaker design pattern? A pattern that prevents a service from making requests to a failing service for a certain period, allowing system stability by stopping rapid retries. 82. What is the Strangler Fig pattern? An approach to gradually replace legacy systems with new microservices by routing parts of the traffic to new services while keeping the old system in place. 83. How do you manage cross-cutting concerns in microservices? Using middleware in frameworks like ASP.NET Core to handle concerns like logging, authentication, and error handling in a centralized man
