Q. What is DevOps ?
Ans - DevOps is a set of practices, tools, and a cultural philosophy that automates and integrates the processes between software development and IT teams. It emphasizes team empowerment, cross-team communication, collaboration, and technology automation.

Q. Cycle Of Devops
Ans - Certainly! The DevOps lifecycle is a series of automated development processes or workflows within an iterative development lifecycle. It aims to optimize the rapid delivery of high-quality software. Let’s explore the seven phases of the DevOps lifecycle:
1. Planning: In this phase, teams define project goals, requirements, and timelines.
Tools: Jira, Trello, or other project management tools.
2. Development: Developers write code based on the project requirements.
Tools: Git, GitHub, or other version control systems.
3. Testing: Automated and manual testing ensures code quality.
Tools: JUnit, Selenium, or other testing frameworks.
4. Deployment: Code is deployed to production or staging environments.
Tools: Jenkins, GitLab CI/CD, or other continuous integration/continuous deployment (CI/CD) tools.
5. Monitoring: Continuous monitoring of applications and infrastructure.
Tools: Prometheus, Grafana, or other monitoring solutions.
6. Feedback: Collect feedback from users, monitor performance, and address issues.
Tools: User feedback channels, log analysis, or other feedback mechanisms.
7. Operations: Maintain and operate the software in production.
Tools: Kubernetes, Docker, or other containerization and orchestration tools.

Q. What is Monolithic and microlithic Architecture ?
Ans -
- Monolithic Architecture: A monolithic application is built as a single unified unit. It is a traditional model where all components (such as the user interface, business logic, and database) are tightly coupled together within one codebase. Key characteristics: Unified: All functionalities reside in a single codebase. Self-contained: The entire application runs as a single process. Updates: To make changes, you need to update the entire stack. Deployment: Deployment involves releasing the entire monolith. Advantages: Easy deployment: One executable file or directory simplifies deployment. Development: Easier development due to a single codebase. Performance: Centralized code can optimize certain functions 2. Microservices Architecture: In contrast, a microservices architecture consists of small, independently deployable services that communicate with each other via APIs. Key characteristics: Decoupled: Each service focuses on a specific business capability. Scalability: Services can scale independently. Updates: Changes affect only specific services. Deployment: Each service can be deployed separately. Advantages: Flexibility: Allows rapid development and deployment of individual services. Scalability: Scales specific services based on demand. Isolation: Faults in one service don’t affect others. /
