What is DevOps? This term is quite familiar in the ears of developers or programmers.
Today, DevOps engineers are what enable IT departments to work together efficiently.
To understand what DevOps is better read our article on DevOps as well as a DevOps engineer.
What is DevOps?
DevOps is actually blending from the term development and operations. This term was invented by Patrick Debois in the early 2000s, to be precise in 2009.
So, you could say the term DevOps appeared recently and started to gain prestige around the 2010s.
DevOps is a set of practices, approaches and tools for managing software development as well as projects based on technology and information technology.
Then, the people who work in this field are called DevOps engineers.
Description of DevOps Engineer
DevOps is a combination of concepts, practices, as well as tools.
Meanwhile, DevOps Engineers are professionals who work as intermediaries for developers, operation teams, system users and management.
The DevOps engineer’s job is to create a user-friendly and integrated system by bridging collaboration between the development, operation and management teams.
To understand the duties of a DevOps engineer, first know what SDLC or System Development Life Cycle is.
This SDLC has several development phases such as planning, analysis, development, implementation, testing and deployment & maintenance.
More details like this:
- Planning – the developer makes a project outline and what is needed.
- Analysis – the developers carry out the research and analysis process.
- Design – project architectural design process
- Implementation – developers build the system.
- Testing – test code that resides in the system.
- Deployment and management – the developer releases the system and manages it to keep it running smoothly.
DevOps Engineer Duties and Responsibilities
There are several responsibilities of a DevOps engineer that must be carried out. These responsibilities include:
Manage System security
Working in the IT infrastructure section, a DevOps also designs a security infrastructure called a cyber-secure system.
1. Project Management
DevOps engineer, must be able to manage various projects. So there are several responsibilities related to this, namely making schedules, holding meetings, making deadlines, checking the work of each team member and conducting assessments, guiding and providing input on projects.
2. Automation of Repetitive Tasks
Repetitive tasks make the tasks that are done less effective, for that, the DevOps engineer is the person who reduces the repetitive tasks.
That way, the developer’s work will be more efficient and faster with minimal errors.
3. Improve IT Infrastructure
DevOps engineers focus on a CI/CD approach that helps them make small changes to parts of the IT infrastructure.
4. Monitor and Report Errors
DevOps engineers regularly monitor software and systems to quickly fix system errors.
DevOps engineers are particularly interested in reducing the time between when a problem is identified (i.e., Time to Detect or TTD) and when it is fixed (i.e., Time to Minimize or TTM).
5. Optimization of Release Cycles
DevOps engineers shorten the system release cycle by minimizing the amount of time and resources required for projects or updates.
DevOps engineers can optimize the release cycle in a variety of methods, such as reducing time-consuming, prioritizing critical components of each release, or introducing new software and technologies.
6. Performance Benchmarking and Testing
DevOps engineers use benchmark testing to monitor day-to-day IT infrastructure operations.
Benchmark testing helps them identify inefficiencies in the system and mitigate problems before they occur.
Each DevOps engineer applies different benchmark tests depending on the organization and project being run, but they all follow the seven principles of benchmarking.
The seven benchmarking concepts are relevance, representativeness, balance, repetition, cost-effectiveness, scalability, openness.
Mandatory Skills of a DevOps Engineer
In the previous section, you learned what the duties of a DevOps engineer are.
To become a reliable DevOps engineer, you need skills or mastery of various tools, software or soft skills in order to work well.
In this section, you will understand some of the mandatory hard skills of a DevOps engineer.
- Understand how to use automation tools such as Jenkins and Bamboo Atlassian.
- Understand how to use VCS (version control system) like Git.
- Can use repository tools such as GitHub, GitLab or BitBucket.
- Understand how to use configuration management tools such as Puppet and Chef.
- Able to understand how to use monitoring software such as Nagios and Raygun.
- Have coding skills and understand programming languages and scripts.
- Mastering container tools such as Kubernetes and Docker.
- Familiar with project management tools such as Trello, Monday, Jira or Confluence.
- Understand what cloud computing or cloud computing is.
- Able to use and develop WordPress.
Meanwhile, when it comes to soft skills, the following are what DevOps engineers must master:
- Communication skills.
- Can collaborate with other teams.
- Able to talk to customers.
- Have problem-solving skills.
- Think creatively and have an open mind.
Becoming a DevOps engineer requires a lot of skills that need to be mastered because there are also many responsibilities.
Although this DevOps engineer is a newcomer in the IT world, this position is quite promising as well.
Through this article, you have understood that DevOps has a complex task as it has to bridge multiple teams and make the developer’s job easier.
If you want to join as one of them, we have also provided you with a discussion of skills that need to be developed, both hard and soft skills.
To work on all IT-based company projects, of course, you need a capable server.
