Day 2 – Enhancing the SDLC & DevOps Prerequisites

🧠 What I Learned Today

🔸 1. DevOps in SDLC

DevOps transforms the Software Development Life Cycle (SDLC) by embedding automation, testing, and monitoring across all phases:

• 📌 Plan → Code → Build → Test → Release → Deploy → Monitor → Feedback

• Instead of sequential steps, DevOps encourages a continuous loop with faster delivery and frequent iterations

🔸 2. Why Jira Matters in DevOps

• Jira is used in the Planning phase to create, assign, and track tasks across development teams.

• It supports:

  • Sprint planning (Agile boards)

  • User stories, bugs, tasks

  • Status tracking (To Do → In Progress → Done)

• Helps teams stay organized and track progress before the code even starts.

🔸 3. Prerequisites to Start DevOps

Before jumping into tools like Jenkins, Docker, or Kubernetes, I need to build a strong foundation in:

• ✅ Git & GitHub

• ✅ Linux commands

• ✅ Basic scripting (Bash/Python)

• ✅ Virtualization concepts

• ✅ Jira (for task tracking)

💬 How I’d Explain DevOps Now

“DevOps is not just CI/CD. It's a complete approach to modernizing SDLC — combining planning (Jira), automation (CI/CD), and monitoring into a continuous feedback loop for faster, better software delivery.”

📎 Bonus: Interview Tip

When asked about planning tools in DevOps, confidently mention:

“We use Jira in the planning stage to manage epics, tasks, bugs, and sprints. It helps sync the Dev and Ops teams even before coding begins.”
