What is DevOps?
DevOps is Development and Operation’s Collaboration, it’s a Union of 3Ps - Process, People and Product (working Product) that enable continuous integration and continuous delivery of value to our end users. DevOps accelerate the process to deliver applications and software services at high speed and high velocity. So that organization can learn and adopt to the market at its earliest. Also, it minimizing the risk factor by continuously delivering and getting end users and stakeholders feedback at the early stages.

What is the need for DevOps?
In Traditional software development, after completing the development part, the code deployment time was huge. And many times, we heard the common fights between the Development Team and Operations Team or deployment team that it works fine on our system, it's the sever causing problem and operation team defenses it's not your server it's your code, Right? Well, DevOps solves the Traditional Dev and Ops fights by breaking the wall of confusion.
-
How DevOps Works?
DevOps is the practice of operations and development engineers that work together in the entire project lifecycle, from the design and development process to production releases and support.
Starting from design and development to testing automation and from continuous integration to continuous delivery, the team works together to achieve the desired goal. People having both development and operations skill sets working together and use various tools for CI-CD and Monitoring to respond quickly to customer's need and fix issues and bugs.

-
What is the significance of having configuration management in DevOps?
Configuration management (CM) assists the team to streamline various tasks and accomplish them in less time. In this way, it enhances the organization’s agility and performance. Also, it assists in providing consistency and enhancing the product development process by implementing means of design streamlining, control, extensive documentation, and change implementation during different phases of the project. You can be aware of configuration management when you go through the devops tutorial.
-
Describe the flow of the DevOps pipeline?
Generally, a pipeline is a set of automated processes that are defined and being followed by the software engineering team. Essentially, DevOps pipeline permits the DevOps software developers and DevOps engineers to competently and consistently compile, create and deploy the software code into production environments.
The corresponding flow is as below:
Developer focus on accomplishing functionality.
The developer sets up his code for the test environment.
Testers work on authenticating the feature. The business team can arbitrate and give feedback.
Developers focus on the test as well as business feedback in a constant collaboration manner.
The code is finally handed over the production and authenticated again
-
What are the key differences between DevOps and Agile?
When preparing for DevOps interviw Questions answer, this is one of the most typical questions a candidate needs to be aware of. There are several similarities between DevOps and Agile methodology. But when it comes to software development, both are fundamentally unique approaches. Here are the differences between the two:
Agile prioritizes timeliness but DevOps provides identical priority to quality and timeliness.
DevOps presents smaller release cycles with instant feedback whereas Agile presents only smaller release cycles without instant feedback.
Agile depends on feedback from customers whereas DevOps depends on feedback from its monitoring tools.
The scope of work is agility only for Agile whereas it is agility and need for automation for DevOps.

Briefly explain various phases in DevOps:
AWS (Amazon Web Services) is a popular cloud provider. It assists DevOps by offering the following benefits:.
When you undergo devops training, you can get familiar with different phases in DevOps. The different phases available in the DevOps lifecycle are as below:
Plan: Firstly, there must be a plan for the type of application required to be developed. It is always a decent idea to get a rough picture of the development process.
Code: The application is coded according to the end-user requirements.
Build: It involves building the application by assimilating different codes created in the previous steps.
Test: Recognized as the most vital step of the application development, it involves testing the application and rebuilding, if necessary.
Integrate: Several codes from different programmers are combined into one.
Deploy: The code is deployed in a cloud environment for future usage. Any new modifications do not influence the overall functioning of a high-traffic website.
Operate: Operations are carried out on the code if needed.
Monitor: The performance of the application is monitored. Modifications are done to fulfill the end-user requirements.
-
What are the antipatterns of DevOps?
A pattern is the one that is most frequently followed by huge masses of entities. When a pattern is accepted by an organization by considering that it is being used by others without determining the requirements of the organization then it turns out to be an anti-pattern. Likewise, various myths around DevOps can lead to antipatterns, they are as below:

Though you Learn DevOps Step by Step, it is important that you know which practices to follow for success in DevOps implementation.
Listed below are the important best practices necessary to be followed for DevOps implementation:
The speed of delivery implies the time taken for a task to continue into the production environment.
It is crucial to calculate the definite or the average time that it needs to recover in case any failure occurs in the production environment.
The number of bugs being mentioned by the customer also influences the overall quality of the application.
-
What is the DevOps toolchain?
DevOps toolchain is formed by a stack of tools. It automates some tasks like the development and deployment of your application. Tasks in DevOps can be carried out manually with easy steps, but the requirement for automation rapidly increases due to the rise in its complexity. Therefore, toolchain automation is important for continuous delivery. Basically, GitHub a Version Control Repository is recognized as the core component of a DevOps toolchain. In this toolchain, some other tools can be delivery pipelines, backlog tracking, etc. When you enroll in the Devops course in Hyderabad, you gradually become aware of various tools and toolchains in DevOps.
-
What does it mean by a branching strategy in DevOps?
Branching is a method implemented for code isolation. It creates a copy of the source code to make two versions that are separately developed. Various kinds of branching are available. Thus, the DevOps team should make a choice based on application requirements. Correspondingly, the choice is referred to as a branching strategy.
-
What is a Puppet?
Puppet is famously known as an open-source configuration management tool being utilized for the deployment, configuration, and management of servers. Essentially, its working is based on client-server architecture. In this architecture, the client is an agent whereas the server is recognized as the master.
