DevOps refers to the combinations of Development and Operational Skills. Basically, to overcome the long, time-consuming process of traditional waterfall models, DevOps are preferred. Nowadays many companies are interested to employ engineers who are skilled at DevOps.It integrates development and operations i.e. it takes a combination of software developers and IT sector. 

Phases of DevOps:

DevOps engineering consists of three phases:

  1. Automated testing
  2. Integration
  3. Delivery

Lifecycle of DevOps:

DevOps mainly focuses on planning, coding, building and testing as the development part. Added is the operational part that includes releasing, deployment, operation, and monitoring. The development and operational part makeup the life cycle.

Team members:

In business enterprises the DevOps engineers create and deliver a software. The main aim of this team, in an enterprise environment is to develop a quality product without the traditional time consumed.

DevOps employs an automated architecture which comes with a set of rules, a person who has worked as a front runner for the organization, will lead the team based on the company’s beliefs and values.

A Senior DevOps engineer is expected the following skills

Software Testing:The responsibility increases along with coding new requirement to test, deploy and monitor entire process as well.

Experience assurance: The person follows the customer idea to develop the end product.

Security Engineer: During development phase the security engineering tools to be used in the security requirements.

On time deployment: The engineer should ensure that the product is compatible and running at client’s end.

Performance Engineer: Ensures that the product functions properly.

Release Engineer: The role of release engineer to address the management and coordination of the product from development through production. Release ensures the coordination, integration, flow of development, testing, deployment to support continuous delivery and maintaining the end-end applications.

  • Jenkins is a powerful application tool that allows the code from the repository using the git plugin and builds it using tools like Ant or Maven.
  • Selenium is an open source automation tool. The Selenium tool performs regression and functional testing. Selenium is used for testing the code from Jenkins.
  • Puppet is a configuration management and deploys testing environment.
  • Once the code is tested, Jenkins send it for deployment on the production server.
  • Then the completion of Jenkins it goes to monitored by tools Nagios.
  • After the monitoring process Docker containers provides testing environment to test the build features.

  • The recruiters should be able to manage multiple projects, simultaneously.
  • They must know the usage of tools for continuous integration and delivery. Such as Cruise control, Jenkins, Bamboo, Travis CI, GOCD, Team foundation server, Team city, Circle CI
  • Testing tools such as Test Complete, Testing Whiz, Serverspec, Testinfra, In Spec, Customer Driven Contracts.
  • Recruiters must know the monitoring tools such as Prometheus, Nagios, Icinga, Zabbix, Splunk, ELK Stack, collected, CloudWatch, Open Zipkin.
