Hello DevOps community! 👋
I'm excited to share the highlights and achievements of my Week 2 in the DevOps journey. This week was intense, insightful, and filled with hands-on experience across AWS, Azure, SSH, Linux commands, CLI tools, and team collaboration frameworks.
☁️ Cloud Platforms – AWS and Azure
This week, I took a deep dive into AWS and Azure, focusing on real-world, hands-on learning.
✅ Key Accomplishments:
✅ Created AWS and Azure accounts.
✅ Launched and configured virtual machines (instances) on AWS.
✅ Learned to create EC2 instances on AWS and manage key configurations.
✅ Successfully connected to AWS instances using SSH via private .pem key files.
⚠️ Major Challenge (And Proud Moment):
I created the instance from Windows, which downloaded the private key file there. Then I had to connect the Ubuntu system to the AWS instance.
To solve this:
I shared the .pem file from Windows to Ubuntu.
Used Add Location via file manager, input the system IP, and securely moved the .pem file.
In VirtualBox, I used Shared Folders to manage file access between host and VM.
This took almost 2 days of research and troubleshooting, but I cracked it! 💪
🔐 SSH, Linux, and Shell Scripting
Understanding how to securely connect and automate processes is vital in DevOps.
💻 Linux Commands Mastered:
history – track command history
ls -ltr, cat, touch, cd, pwd – navigation and file handling
nproc – check CPU cores
chmod 777 – permission setup
sudo – run commands as superuser
💡 SSH & Shell Scripting:
Connected to EC2 instances using ssh -i "key.pem" ubuntu@ip-address.
Created automated tasks via Shell Scripting, instead of executing commands one by one.
Sample shell workflow:
bash
Copy
Edit
!/bin/bash
sudo apt update
sudo apt install apache2 -y
echo "Apache Installed Successfully!"
🧠 AWS CLI and S3
I also started working with AWS CLI to perform cloud operations from the terminal.
📁 Hands-On with AWS CLI:
Installed and configured AWS CLI using aws configure.
Created S3 buckets using CLI.
Uploaded folders and files to AWS S3 via CLI.
Learned to manage access policies and permissions.
👨💼 Team Collaboration & Agile Methodologies
This week, I also explored how cross-functional teams work in a DevOps environment.
🧩** Understanding Team Roles:**
*Business Analyst *– Gathers user requirements.
Product Owner – Prioritizes and refines requirements.
Product Manager – Aligns product roadmap and business goals.
Software Architect – Designs system architecture.
*UI/UX Designer *– Plans user interface and experience.
Developers – Implement features.
QA/Testers – Ensure quality through testing.
DevOps Engineer – Bridges development and operations.
SRE (Site Reliability Engineer) – Ensures system uptime and performance.
📘 Tools Explored:
Jira – For Agile documentation, sprint planning, and issue tracking.
Scrum Framework – Learned ceremonies like Sprint Planning, Daily Standups, Reviews, and Retrospectives.
🛠️ Infrastructure as Code (IaC)
While I haven’t used it yet, I explored Terraform and learned that:
It's a powerful Infrastructure as Code tool.
It supports multi-cloud platforms like AWS, Azure, and GCP.
Will be focusing on it in upcoming weeks for automated deployments.
🔚** Week 2 Summary**
✅ Created and connected virtual machines on AWS & Azure
✅ Managed private key sharing between Windows and Ubuntu
✅ Mastered shell scripting and basic Linux CLI
✅ Configured and used AWS CLI to manage S3 buckets
✅ Learned DevOps team structure and Agile collaboration
✅ Explored tools like Jira and Scrum
✅ Discovered Terraform and IaC principles
🚀 Onward to Week 3…
Week 2 was all about getting hands-on, solving real-world issues, and building confidence.
I'm excited to go even deeper into automation, CI/CD, and containerization in the next leg of my journey.
