Key Takeaways from Week 1

🖥️ Virtual Machine Fundamentals & Practical Setup

✅ Explored the evolution of VMs and their importance in modern cloud infrastructure.
✅ Hands-on practice: Created VMs on AWS (EC2) & Azure, configuring instances, networking, and storage.
✅ Understood hypervisors (VMware, Xen) and how cloud providers manage virtual environments.

🔐 Secure VM Access via CLI: Efficiency & Security

✅ Learned to connect to EC2 instances securely via SSH, avoiding AWS console dependency.
✅ Example: Connecting to an EC2 instance using SSH:

shCopyEditssh -i "path/to/my/keypair.pem" ubuntu@<public-ip-address>

✅ Security best practice: Setting the correct permissions for key pairs:

shCopyEditchmod 600 "path/to/my/keypair.pem"

✅ Used iTerm (Mac) 🖥️, PuTTY (Windows) 🏢, and Mobile Xterm 📱 for remote access.

🚀 AWS CLI: A Deep Dive into Automation

The AWS CLI was the star of the week, enabling faster and more efficient cloud management.

✅ Configured AWS CLI:

shCopyEditaws configure

✅ List existing S3 buckets:

shCopyEditaws s3 ls

✅ Create a new S3 bucket:

shCopyEditaws s3 mb s3://my-unique-bucket-name

✅ Automate EC2 instance creation:

shCopyEditaws ec2 run-instances --image-id ami-12345678 --count 1 --instance-type t2.micro

✨ This eliminated manual effort, reducing errors and improving efficiency.

---

📜 Beyond CLI: Infrastructure as Code (IaC)

✅ Explored AWS CloudFormation Templates for Infrastructure as Code (IaC).
✅ Learned Terraform 🆚 AWS CDK, comparing cloud-specific vs. multi-cloud automation.
✅ Understood IaC benefits: repeatability, consistency, and scalability in cloud deployments.
