If you are in the tech field or a student, you should have heard a word called "DevOps".

you may have wondered, what is this thing? I got confused when I heard the "DevOps" word for the first time. I think it's your time to get some knowledge about DevOps. Let's dive into DevOps..

What does a DevOps engineer do?

Basically, in a software team, there is a programming team, a testing team, operating team. So, at first developers in a programming team code and add codes or deduct them. then they hand over it to the testing team. This Testing team tests the code by creating a new code etc . once it passes the tests. it is passed to the operating team. The operating team maintains the servers and ensures no downtime of the service. Also, they handle the huge traffic. so, you can see here some people develop the software, and the operations team manages the other stuff. In case of any communication error between them, things won't work in a they have to.

Here comes the role called DevOps, which means development + operations. let's see the concepts and tools used in DevOps

let's see the concepts and tools used in DevOps

DevOps includes concepts like Build Automation, CI/CD, infrastructure as code, etc.. and these are numerous tools that enable these concepts to be implemented because there are a vast number of tools, it can get confusing and overwhelming.

DevOps Roadmap to Get Started as a DevOps Engineer

I. Foundational Skills:

  • Linux Fundamentals: Get comfortable with the command line, understand file systems, and learn basic scripting languages like Bash or Python. Resources: The Linux Command Line, Automate the Boring Stuff with Python.

  • Version Control: Master Git for code versioning, branching, and collaboration. Resources: Git SCM - book by Scott Chacon, Git Essentials interactive course.

  • Networking Basics: Understand IP addresses, subnetting, DNS, and common network protocols. Resources: Network+ certification study guide, CCNA certification courses.

II. DevOps Core Concepts:

  • Infrastructure as Code (IaC): Learn tools like Terraform or Ansible to automate infrastructure provisioning and configuration. Resources: Terraform by HashiCorp, Ansible for Beginners course.

  • Continuous Integration/Continuous Delivery (CI/CD): Implement automated pipelines for building, testing, and deploying code. Resources: Jenkins, CircleCI, GitHub Actions documentation.

  • Configuration Management: Explore tools like Puppet, Chef, or Ansible to manage configurations consistently across environments. Resources: Puppet Documentation, Chef documentation.

  • Monitoring & Observability: Set up tools like Prometheus, Grafana, or Datadog to monitor application and infrastructure health. Resources: Prometheus documentation, Grafana tutorials.

III. Specializations & Advanced Skills:

  • Cloud Computing: Choose a major cloud provider (AWS, Azure, GCP) and learn their services for infrastructure, storage, and computing. Resources: AWS Certified Solutions Architect, Azure Fundamentals certification, Google Cloud Architect certification.

  • Containerization: Understand Docker and Kubernetes for containerized deployments and orchestration. Resources: Docker documentation, Kubernetes documentation.

  • Security: Integrate security practices into your DevOps processes, including threat modeling and vulnerability scanning. Resources: OWASP Top 10, SANS Institute security courses.

IV. Continuous Learning & Community:

  • Engage with online communities: Participate in forums like r/devops, read blogs by industry experts, and attend conferences like DevOps Days.

  • Contribute to open-source projects: Gain practical experience and learn from others by contributing to open-source DevOps tools.

  • Get certified: Consider industry-recognized certifications like AWS Certified DevOps Engineer or Certified Kubernetes Administrator.

Remember:

  • This roadmap is a flexible guide, adjust it based on your interests and career goals.

  • Don't be afraid to experiment and explore new technologies.

  • Build your network and connect with other DevOps professionals.

  • Never stop learning - the DevOps landscape is constantly evolving.

I hope this roadmap empowers you to navigate your exciting journey in the world of DevOps!
