A better understanding of DevOps Services.

Devops Services

A better understanding of DevOps Services can be simply put as a combination 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. DevOps integrates development and operation i.e. it takes both software developers and IT sector. DevOps engineers must play nice as they have to collaborate, and handle an automated infrastructure, workflow and continuously measuring application performance.

DevOps Service Phases

DevOps engineering consists of three phases:

1. Automated testing

2. Integration

3. Delivery

The lifecycle of DevOps

DevOps Services 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 make up the life cycle.

Team members of DevOps

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

The DevOps Service 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 requirements to test, deploy and monitor the entire process as well.

Experience assurance:

The person follows the customer’s idea to develop the end product.

Security Engineer:

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

On-time deployment:

The DevOps Service engineer should ensure that the product is compatible and running at the 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.

System Admin:

Traditionally system admin focuses only on the server running. But DevOps Services handles the open-source pros, passionate towards technology, hands-on with development platforms and tools. They maintain the networks, servers, and databases and even support.

Most popular DevOps tools

Git is a version control system tool

Jenkins, Selenium are Continuous Integration Testing tools that use predefined frameworks.

Puppet, Chef, Ansible are configuration management and deployment tools

Nagios is a Continuous monitoring tool

Docker is a container concept tool.

Usage of the DevOps tools

  • Git tool is a version control system tool that is used to develop the source code by developers and sent to the Git repository and we have to edit the code in repository.
  • 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 the testing environment.
  • Once the code is tested, Jenkins sends it for deployment on the production server.
  • Then the completion of Jenkins goes to monitored by tools Nagios.
  • After the monitoring process Docker containers provides a testing environment to test the build features.

Basic technical Knowledge for DevOps recruiters

  • The DevOps Service recruiters should follow the basic methodologies such as agile, continuous delivery, continuous integration, microservices, test-driven development, infrastructure as a code.
  • They must know the basic scripting languages such as Bash, Python, Ruby, Perl, Php.
  • The recruiters must know the infrastructure automation codes such as puppet, chef, Ansible, Salt, Terraform, Cloud Formation, and Source code management such as Git, Mercurial, Subversion.
  • The developers should study about cloud services such as AWS, Azure, Google cloud, open stack.
  • Another skill is orchestration. In programming, to manage the interconnections and interactions among the private and public clouds.
  • The next one is containers, a method of OS virtualization that allows you to run an application and its dependents in resource-isolated processes. it includes LXD, Docker.
  • 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.
