DevOps Practices in Cloud Computing Questions and Answers for Viva

Answer-1: Artifacts are stored in repositories such as JFrog Artifactory or AWS CodeArtifact.

Answer-2: Cloud-native DevOps leverages cloud services and architecture for scalable, efficient software delivery.

Answer-3: GitOps is a practice where Git is the single source of truth for declarative infrastructure and application code.

Answer-4: It ensures code quality and reliability by automatically validating changes before deployment.

Answer-5: Unit tests, integration tests, UI tests, and performance tests.

Answer-6: Secrets are stored securely using tools like HashiCorp Vault, AWS Secrets Manager, or Azure Key Vault.

Answer-7: Feedback loops help teams quickly identify and fix issues, enabling continuous improvement.

Answer-8: Collaboration between dev, ops, and QA teams fosters faster releases and higher quality software.

Answer-9: It allows automatic resource provisioning, helping DevOps teams manage traffic and workloads effectively.

Answer-10: Site Reliability Engineering (SRE) applies software engineering to infrastructure and operations, enhancing reliability.

Answer-11: Use load balancing, redundancy, and failover mechanisms across cloud regions.

Answer-12: Observability provides deeper insights into system internals using metrics, logs, and traces.

Answer-13: A release pipeline defines the stages for software promotion from development to production.

Answer-14: Policy as code manages and enforces policies using code, improving compliance and governance.

Answer-15: Immutable infrastructure means servers are never modified after deployment?instead, new instances replace old ones.

Answer-16: Examples include Kubernetes, Helm, Istio, and Spinnaker.

Answer-17: By integrating security tools in CI/CD, performing code scanning, and managing secrets properly.

Answer-18: Chaos engineering tests system resilience by introducing failures intentionally to observe and improve system behavior.

Answer-19: CI is about merging and testing code frequently; CD automates the deployment of tested code.

Answer-20: Faster time to market, better scalability, reduced errors, higher quality releases, and improved collaboration.

Answer-21: DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the development lifecycle and deliver high-quality software continuously.

Answer-22: Cloud provides scalable infrastructure, automation tools, and services that simplify CI/CD, monitoring, and collaboration.

Answer-23: Collaboration, automation, continuous integration, continuous delivery, monitoring, and feedback.

Answer-24: Continuous Integration (CI) is the practice of merging code changes frequently and automatically testing them to detect issues early.

Answer-25: Continuous Delivery (CD) is the practice of deploying code changes to a staging environment automatically after testing.

Answer-26: Continuous Deployment is the automated release of validated code to production without manual intervention.

Answer-27: Jenkins, Git, Docker, Kubernetes, Terraform, Ansible, and monitoring tools like Prometheus.

Answer-28: IaC is the management of infrastructure using code, allowing for automated and consistent infrastructure provisioning.

Answer-29: Popular IaC tools include Terraform, AWS CloudFormation, and Azure Resource Manager.

Answer-30: Version control systems like Git track code changes, enabling collaboration and rollback when necessary.

Answer-31: Automation reduces errors, speeds up deployments, and allows teams to focus on innovation.

Answer-32: Containerization is packaging an application with its dependencies into a container for consistent deployment across environments.

Answer-33: Docker is the most widely used containerization tool.

Answer-34: Orchestration automates the deployment, scaling, and management of containerized applications, often using Kubernetes.

Answer-35: Jenkins is an open-source automation server used for building, testing, and deploying applications.

Answer-36: Cloud-native DevOps focuses on microservices, containers, and serverless technologies to leverage cloud scalability and flexibility.

Answer-37: A CI/CD pipeline is a series of automated steps to build, test, and deploy code.

Answer-38: Blue-green deployment is a release strategy that runs two production environments and switches traffic between them to minimize downtime.

Answer-39: Canary deployment rolls out updates to a small subset of users before a full rollout.

Answer-40: DevSecOps integrates security practices into the DevOps pipeline to ensure secure software development and deployment.

Answer-41: Monitoring involves observing application performance and infrastructure to detect and resolve issues proactively.

Answer-42: Prometheus, Grafana, Datadog, ELK Stack, and CloudWatch are popular monitoring tools.

Answer-43: A rollback is reverting an application to a previous version due to a failed deployment or issue.

Answer-44: Serverless computing allows running code without managing servers, automatically scaling with demand.

Answer-45: It simplifies deployment, reduces infrastructure management, and accelerates development.

Answer-46: Microservices architecture breaks applications into small, independent services that are easier to develop, deploy, and scale.

Answer-47: They enable independent deployments, reduce development complexity, and support faster delivery cycles.

Answer-48: Configuration management ensures systems are set up consistently across environments.

Answer-49: Ansible, Puppet, and Chef are common tools.

Answer-50: A build artifact is a file or set of files created from the build process and deployed in later stages.
