WHAT IS DEVOPS?
Devops is a clipped compound of Development and Operations.
Bass, Weber, and Zhu have proposed Devops definition as follows
“DevOps is a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production while ensuring high quality”
From the above diagram, we can say that Devops is an intersection of software engineering Development, operations and Quality Assurance (QA).
DevOps works in a cross-functional mode rather than the single tool. There are a set of or multiple tools in DevOps. They are worked for a particular task. In the below fig we can observe stages in DevOps toolchain.
DevOps is basically an escalation from traditional software development models by using cloud technologies, automation, and standardization.
TOP DEVOPS TOOLS:
Git: It provides a path to combine all teams who are working on the same project and located at different places.
Docker: It comes under containerization technology. The container contains various applications used in depending situations. We can deploy these containers on any machine without caring about underlying host details.
Selenium: It is an automated testing framework; we can perform application testing by using this tool.
Jenkins: It is used to create continuous delivery pipelines.
Ansible: It works on Unix. Used for automated software provisioning, configuration management, and application deployment.
Puppet: It is an alternative tool for the Ansible. It supports both operating systems Unix and Windows.
Nagios: It is used for the monitoring purpose. It monitors server, application, and networks.
Chef: It is used for configuration management purpose.
SVN: It is also called subversion. It is an alternative tool for Git.
Rational ClearCase: Rational ClearCase manages changes across the software lifecycle. ClearCase is used in Software configuration management of source code. ClearCase is used in both hardware and software development. The center of ClearCase is a secure data repository. It has data that is shared by all users including accounting data and historical data on development processes itself. It shows details like which user implemented which version, when and why.
Maven: It is an automation tool used for building purpose.
Apache Ant: It is a software tool used for building purpose.
Kubernetes: It is used for continuous deployment and auto-scaling of container clusters.
THE BENEFITS OF DEVOPS:
- Continuous software delivery
- Less complexity to manage
- Faster resolution of problems
- Happier, more productive teams
- Higher employee engagement
- Greater professional development opportunities
- Faster delivery of features
- More stable operating environments
- Improved communication and collaboration
- More time to innovate (rather than fix/maintain)
