🛠What is DevOps ?
👩💻 Aspiring DevOps & Cloud Engineer | Learning in Public | Automation Enthusiast Hi! I’m Vaishnavi Landge, documenting my journey into DevOps, Cloud, CI/CD, and automation. I believe in learning by doing — this blog is my daily space to simplify concepts, share projects, and grow step by step. 🚀 Let’s build, automate, and deploy — together!
🚀 Welcome to Day 1 of “The CloudOps Journal” — my daily DevOps & Cloud learning journey! I’m Vaishnavi Landge, an aspiring DevOps Engineer, documenting everything I learn so others can follow along. In today’s article, let’s break down one of the most searched — yet misunderstood — questions: What exactly is DevOps?
📌 What is DevOps?
DevOps is a culture, practice, and set of tools that combines software development (Dev) and IT operations (Ops) to shorten the system development life cycle — while delivering high-quality software continuously.
But DevOps is not a tool or a single technology. It's a philosophy of collaboration, automation, and continuous improvement.
🔍 Why DevOps? (The “Before DevOps” Story)
Before DevOps came into the picture, the tech world had a serious problem: “The Wall of Confusion.”
🧱 Before DevOps:
Developers would write code and throw it over the wall to operations.
Operations would be responsible for deployment, stability, and uptime.
No feedback loop. Lots of blame. Slow releases. Tons of bugs.
This led to:
Delayed software delivery
Manual errors in deployments
Poor collaboration between dev & ops
"It works on my machine" syndrome
💡 Why DevOps Came Into Existence:
Companies needed to move fast and release often (think Amazon, Netflix).
Manual deployments weren’t scaling.
Collaboration was critical — not optional.
That’s where DevOps was born — to bridge the gap between Dev and Ops, and automate the pipeline from development to deployment.
🧠 Things to Know Before Getting Into DevOps
Before diving into tools like Docker or Kubernetes, it’s essential to understand the mindset and foundation of DevOps.
Here’s what you should get comfortable with:
| Area | Why It Matters |
| Basic Linux Commands | Almost everything in DevOps runs on Linux |
| Networking Concepts | Ports, DNS, firewalls — crucial for deployments |
| Version Control (Git) | CI/CD starts with source control |
| Programming Basics (Python/Shell) | For scripting and automation |
| Cloud Basics (AWS/GCP/Azure) | DevOps = Cloud-first approach |
| CI/CD Concepts | Know what happens from push to production |
| Containers & Virtualization | Understand Docker before K8s |
🔄 DevOps Lifecycle (The Real Flow)
Think of DevOps as a continuous loop where everything feeds into everything else. It’s not a start-to-end process — it’s a circle of improvement.
🌀 Key Phases in the DevOps Lifecycle:
Plan – Gather requirements, plan features.
Develop – Code using best practices.
Build – Compile code into executable units.
Test – Automate tests to catch bugs early.
Release – Push code into staging/production.
Deploy – Use tools like Jenkins, GitHub Actions, etc.
Operate – Monitor system health, scale as needed.
Monitor – Use logging and alerting tools for insights.
🔁 Then, go back to Plan based on feedback.
Tools involved (we’ll explore these later):
Git, Docker, Kubernetes
Jenkins, GitHub Actions, Terraform
Prometheus, Grafana, AWS, NGINX
👩💻 Roles & Responsibilities of a DevOps Engineer
As someone aspiring to become a DevOps Engineer, here’s what I’ve learned DevOps engineers actually do:
| Role | Description |
| CI/CD Pipeline Creator | Automates the flow from code push to production |
| Infrastructure Automator | Uses tools like Terraform or Ansible |
| Cloud Architect (Lite) | Knows how to deploy on AWS/GCP |
| Monitoring Specialist | Uses tools to detect issues before users do |
| Security Gatekeeper | Adds security checks in pipelines |
| Collaboration Champion | Works with developers, testers, ops, and cloud teams |
DevOps isn’t a single job — it’s a mindset and a toolbox. You may not master it all in a week, but with daily practice (like this blog!), it’s totally doable.
✍️ My DevOps Learning Vision
As I begin this journey, I’m not just learning tools — I’m learning how to think like a DevOps Engineer. I’ll be writing daily about:
Real-world tools (Docker, AWS, Jenkins, Terraform)
Problems I face and how I solve them
Concepts I wish I understood earlier
If you're also starting out — let's grow together. 🌱
📢 Final Thoughts
DevOps isn’t just a buzzword — it’s a modern way of building software.
DevOps is no longer optional — it’s essential.
Stay tuned for Day 2: All about Linux.
