Now you all might be wondering what is DevOps?
DevOps is basically a short term known for Development and Operations.
As you all know that something that is developed undergoes a lot of process, it may include the brainstorming for the given requirement,to find out the technology to be used, thorough analysis of the output required, the architecture needed for the development, the efficient coding language to be used, to write a script for the client analysis, to purchase a server for hosting the code, follow the agile method for the code development, to the scrum and daily extensive testing procedures to ensure timely delivery of the projects. So many people are involved working together as a team to ensure the requirement is met and project is delivered. All the process comes under the Development Lifecycle of the Project.
Now once the project is completed, so need to ensure the deployment part, the hosting part, and the domain and other access configurations where the the project will be accessible to the end user, it may on any instance, on cloud or the server hosted by various tech giants out there. To ensure the monitoring of the developed code, to check for the pipelining the robustness of the website or the application developed, to an android or iOs app to check for their smooth functioning to avoid hassle free and bug free delivery comes under maintenance or the Operations part of the Project.
Now the person responsible for conducting and follow all these processes to ensure conformity and running standards of the Developed applications are know as DevOps.
So now what are the DevOps responsible for?
A DevOps engineer is responsible for mainly these things
- To be able to use a good range of tools, technologies, services, languages both open source and paid like(AWS, Red Hat, Google)
- They know how to develop i.e. programming and scripting where required.
- Deal with the servers, their monitoring, their architecture setup, IT operations and system uptime.
- Deployment of the server and automation of the deployment via coding scripts, and frequent testing of the deployed code, check server compatibility, memory acquired and possible glitches that may arise.
- Automation knowledge via scripts or available softwares for the same.
- Efficient Management of the memory allocation and data.
- To be capable of designing the structure to allow maximum use of the server and code to potential furthur good results in business
- To communicate and collaborate to overcome the functional and nonfunctional obstacles.

A good DevOps engineer can take the company a few extra miles,it can be a game changer and can totally change the scenario of any existing company. As a Devops engineer, it will always be ensured that the system works smoothly and is being constantly monitored across the platform to resolve the immediate alerts and warnings that arises, or the issues are aptly addressed whenever they occur. To ensure the server and the files on the server are updated whenever new code or development occurs to ensure proper RAM size and that no functionally repeated tasks are present, as the time increases and company grows the processes are automated to increase the productivity of the work done so the programmers can focus on logic building part of the application.
Planning & Codebase : To plan and provide task breakup and Ballpark estimate we can use ATLASSIAN tool JIRA, for code management and version control GIThub & GIT whose commands are necessarily required for code management and data provisioning. SVN or subversion to maintain and reflect the code merge and for maintaining the codebase.
Building : To build the code developed we need a build tool, to download the configurations of the services required aur the imports in the projects e.g: Maven, Gradle
Testing: Testing is mostly automated and for automation testing Selenium is the famous tool other than JUNIT which mostly is related to Java test cases. Jenkins is also one of the famous testing tool for devops environment.
Deployment : To automate the code commits and code check ins to deploy on various servers and instances we use puppet and chef.It is one of the major configuration management systems on Linux, along with CFEngine, Ansible and Puppet. More than a configuration management tool,Chef, along with Puppet and Ansible, is one of the industry\’s most notable Infrastructure as Code (IAC) tools.
Operate : To support infrastructure as code. Salt is a Python-based configuration management tool and remote execution engine which eases approach to deployment and cloud management. Red Hat ansible also is another tool designed for the same.
Monitoring : Nagios, sensu and New relic, pagerduty, cloudmap are few of the server monitoring tools available.
So, DevOps is the most integral part of any organisation that can handle the last phases of project delivery and handle the issues that arises on the server setup.
