Course Description

What is DevOps?

DevOps is a set of practices that combine software development (Dev) and IT operations (Ops) to deliver software services faster, more reliably, and with improved quality.

What are the benefits of DevOps?

DevOps benefits include faster time to market, improved collaboration and communication between teams, increased efficiency and productivity, and improved quality and reliability of software services.

What are some popular DevOps tools?

Some popular DevOps tools include Jenkins, Git, Docker, Kubernetes, Ansible, Chef, Puppet, and Nagios.

What is continuous integration?

Continuous integration (CI) is a software development practice where developers frequently integrate code changes into a shared repository, and automated build and test processes are triggered to detect and fix issues as early as possible.

What is continuous delivery?

Continuous delivery (CD) is a software development practice where software changes are automatically built, tested, and deployed to production environments in a continuous and efficient manner.

What is a container?

A container is a lightweight, portable unit of software that packages an application and all its dependencies into a single executable package that can run consistently on any infrastructure.

What is Kubernetes?

Kubernetes is an open-source container orchestration system that automates the deployment, scaling, and management of containerized applications.

What is infrastructure as code?

Infrastructure as code (IaC) is a software engineering practice where infrastructure components such as servers, networks, and storage are defined and managed using code and automation tools.

What is microservices architecture?

Microservices architecture is a software development approach where applications are built as a collection of small, independent, and loosely-coupled services that can be deployed and scaled independently.

What is monitoring in DevOps?

Monitoring in DevOps is the practice of observing and measuring the performance, availability, and reliability of software services, and using that data to optimize and improve the services.

What is version control?

Version control is the process of managing changes to files and documents over time, allowing multiple users to work on the same file and maintain a record of all changes made.

What is agile software development?

Agile software development is an iterative and collaborative approach to software development that emphasizes flexibility, customer satisfaction, and rapid delivery of working software.

What is a pipeline in DevOps?

A pipeline in DevOps is a sequence of automated tasks and processes that together build, test, and deploy software services.

What is the difference between Git and SVN?

Git is a distributed version control system that allows multiple developers to work on the same codebase and merge changes independently. SVN is a centralized version control system that requires a central repository and requires developers to synchronize their changes with the central repository.

What is the difference between Docker and VMs?

Docker is a containerization technology that allows multiple applications to run on the same host, each in its own isolated container. VMs are virtual machines that run on a host operating system, with each VM running its own guest operating system.

What is the role of DevOps in cloud computing?

DevOps plays a critical role in cloud computing by providing the tools, practices, and processes needed to deploy and manage applications in the cloud, with a focus on automation, scalability, and reliability.

What are some common challenges faced by DevOps teams?

Common challenges faced by DevOps teams include managing complex infrastructure, integrating multiple tools and systems, ensuring security and compliance, and maintaining effective communication and collaboration between teams.

What is a configuration management tool?

A configuration management tool is a software tool that automates the process of configuring, managing, and monitoring IT infrastructure components, such as servers, networks, and storage.

What is Resilience Testing?

Resilience Testing is a software process that tests the application for its behavior under uncontrolled and chaotic scenarios. It also ensures that the data and functionality are not lost after encountering a failure.

Can you differentiate between continuous testing and automation testing?

The difference between continuous testing and automation testing is given below:

Continuous Testing	Automation Testing
This is the process of executing all the automated test cases and is done as part of the delivery process.	This is a process that replaces manual testing by helping the developers create test cases that can be run multiple times without manual intervention.
This process focuses on the business risks associated with releasing software as early as possible.	This process helps the developer to know whether the features they have developed are bug-free or not by having a set of pass/fail points as a reference.
