1. What is DevOps?

Probably the most important segment of this DevOps Tutorial. Tools and practices that enable the organization to operate effectively, solving challenges, fortifying the strength to deliver within a shorter time, and be ahead of competitors. DevOps uses software development and infrastructure management process by the evolution of products for faster delivery of applications and services.  

2. DevOps Tool list          

The next part of this DevOps tutorial is about DevOps Tools. Following are some of the DevOps tools 

  • Docker
  • Ansible
  • Git
  • Puppet
  • Chef
  • Jenkins
  • Nagios
  • Splunk

3. Kubernetes Vs Docker

Kubernetes Vs Docker is yet another crucial concept of this DevOps tutorial. The deployment of applications from one computer to another instantly, conveniently, and reliably is a crucial aspect of an organization’s business requirements and DevOps team routine workflow. 

The deployment of application management convenient for all team sizes has spiked in recent years, simultaneously the virtual machines as computing resource has reached their culmination in virtualized data centers.

4. Continuous Integration

 Continuous integration is a process of continuous development of code into the repository, many times a day. Every integration is verified using automated build and test, automated testing is implied to assess the functionalities of the code. Based on the source code modifications for fixing the bug that needs to be consolidated into the repository source. 

5. Continuous Deployment and Delivery 

 Continuous delivery is a practice by the software team to develop, build test and release software in momentary cycles. Continuous deployment is a task involving qualified modifications in the software code or architect, and are deployed to production instantaneously as they are organized without any human intervention. Continuous delivery is a progression of continuous integration as it automatically deploys to production without any human intervention with verifications done by automation testing. 

6. Version Control

A source tool that envisages the practice of tacking and handling the modifications performed on a software code. Version control systems are software tools that aid the software team in managing the source code. Version control enables developers to store and retrieve the data by previous developers that help in understanding their contributions by seeing previous version documents. 

There are three types of version control systems 

  • Local version control system
  • Centralized version control system
  • Distributed version control system 

An example of version control is a part of software configuration management where alterations are identified by a letter or number code, either as revision number, level, or simply revision. 

7. How to become a DevOps Engineer

DevOps engineer skills 

  • Programming knowledge or knowing how to write code
  • Knowledge of a system administrator such as network and storage
  • Infrastructure managing and compliance, automation tools
  • Virtualization and cloud
  • Security, testing
  • Good communication skills
  • Software is functional to be released to the market
  • Quick and efficient feedback and progress
  • Lesser risks
  • Better yield 
  • Continuously automated development of the code 
  • Coding for application
  • Scripting knowledge and various configuration and deployment tools
  • Knowledge about Linux, OpenStack, and public clouds such as Azure, AWS, and continuous integration
  • They deal with connections, data, storage concepts, and they should have a good understanding of IT networks, real-time systems with a wide variety of protocols, API, and the appropriate decision for infrastructure support. 

Working as a comprehensive unit with the business team managing the workflow while making the software function by integrating it with an automated process. 

A procedure that reduces the time taken for software development, the main feature for DevOps is automation, and continuous improvement, delivery, creativity, and knowledge. Software development accelerates growth with these practices.

8. Top DevOps Interview question and answers

  • What is your knowledge about DevOps?

A process to coordinate efforts of operations and development team to magnify the delivery of software products with reduced failure. A value-based approach where development and software engineers work hand-in-hand throughout the product or service lifecycle. 

  • How DevOps differ from agile technology?

DevOps is a custom integration of development and operations team working for continuous development, testing, integrating, deployment, checking throughout the lifecycle.

Agile is a software procedure focussing on iterative, incrementing, minute software releases along with customer feedback. It remits gaps and conflicts between customers and the coders. 

  • What are the phases in the DevOps?

Planning- a plan for a type of application

Code: a code according to user specifications

Build: Application building by incorporating various codes from the previous steps

Test: Application test and build 

Integrate: Integrate different programmers code into one

Deploy: Code is deployed into the cloud interface for further use, the new modifications do not alter the performance of high traffic websites.

Operate: Operations are done on the code if required. 

Monitor: The performance of an application is monitored where alterations are made to match the end-user specifications.

Mention a few benefits of DevOps.

9. Technical advantages

  •  Uninterrupted software delivery
  • Fewer complex problems for management
  • Faster detection and defect rectifications

Conclusion

To wrap up this DevOps Tutorial, DevOps is a software integrated approach for providing user-specific functional software to be delivered in a fast and efficient manner. Releasing software on a routine basis and with frequent deployment, with the organization prepared for the process. This function is adaptable to new intonation releases.
