What is a "good" DevOps Engineer?
An individual who possesses the communication and teamwork skills necessary to execute the end-to-end DevOps pipeline smoothly across the development, build, test, release, deploy, etc., and monitor stages is referred to as a DevOps engineer.
DevOps engineers are crucial to an organization's success because they:
Increases the frequency of software releases to hasten the release of new products and the advancement of existing ones.
Increased dependability: Delivers software that is error-free and optimized by incorporating testing into every stage of the SDLC.
Low-risk scalability: Encourages uniformity and standardization throughout the SDLC to accommodate more features and new products.
Reduced bottlenecks: Due to close coordination with the operations team, issues are identified and resolved more quickly.
Increased effectiveness utilizes automated testing and security tools to speed up release processes.
Technical Knowledge Required for DevOps Engineers
Building an online presence, developing software for external clients, making tools for internal teams and team members, and optimizing software that has already been purchased are a few of the motivations behind software development. However, because of the DevOps skills gap, many organizations now find it difficult to develop software.
Learn the following skills to position yourself for a position on a DevOps team and help close the development and operations skills gap.
1. Knowledge of the basics of Linux and scripting
Linux fundamentals, including file handling, system administration, text processing, and process management, are essential knowledge for a DevOps engineer. They should also be familiar with Linux server administration and scripting languages like Python.
2. Understanding of Key Tools and Technologies
The DevOps tools engineers should be familiar with include version control, continuous integration servers, configuration management, containers, and deployment automation. They should also be knowledgeable about network protocols, monitoring and analytics software, testing and cloud quality tools, and infrastructure orchestration.
3. Cloud Expertise
A DevOps engineer needs to be proficient in cloud computing, including network and database management. They must also be familiar with Google Cloud Platform, Microsoft Azure, and Amazon Web Services (AWS).
4. Coding Knowledge
5. Automation Knowledge
Every DevOps engineer should be proficient in automation and able to automate the entire DevOps pipeline. They need to comprehend CI/CD pipelines, app performance monitoring, infrastructure and configurations, and more. It's also crucial to be familiar with open-source automation tools like Ansible and source code management (SCM).
6. Testing Skills
The ability to identify bugs in software projects and products is a requirement for DevOps engineers, so proficiency in automation testing is essential. These IT professionals should have a solid understanding of virtualization and be skilled with testing tools like Puppet, Chef, and Docker. Additionally, they should be able to integrate Jenkins and Selenium, as well as run tests for an entire DevOps automation pipeline.
7. Security Knowledge
All IT professionals, but especially DevOps engineers, require security expertise. Code analysis, change management, threat analysis, security education, and vulnerability assessment are just a few of the DevSecOps skills.
8. Active Monitoring Capabilities
A DevOps engineer must be familiar with proactive monitoring as part of their duties. They should be able to identify production system bottlenecks, apply security patches, and upgrade system versions. They should be familiar with monitoring tools like Nagios and Splunk.
9. Capacity for Containerization
To perform their duties effectively, DevOps engineers need to be familiar with container-related tools. Docker Engine, LXC, container registries, Docker Swarm, systemd-nspawn, and Kubernetes are a few examples.
10. Skills for Continuous Integration
A DevOps best practice called continuous integration (CI) enables developers to merge software updates multiple times a day into the main branch. The ability to automatically integrate code changes from numerous developers into a single software project should be possessed by DevOps engineers.
11. Version Control Capabilities
A DevOps engineer needs to be proficient in version management because it helps them keep track of and manage software code changes. Key version management skills include being able to use tools like Jenkins, Maven, and Git.
Soft Skills and High Principles
Just being proficient in automation and coding is insufficient. A different version of you—one who excels at soft skills, self-motivation, flexibility, and learning—is required for DevOps. Professionals in devops should be both doers and listeners.
They should make it abundantly clear that the DevOps transformation entails collaboration-driven stakeholder discussions, awareness of business goals, assessment, and identification of improvement areas.
You need a blend of inborn soft skills and technical knowledge to be successful in the DevOps career path. Together, these two essential characteristics support your development. Your technical expertise will enable you to build a DevOps infrastructure that is incredibly productive. Soft skills, on the other hand, will enable you to deliver the highest level of client satisfaction.
