Local Cloud Infrastructure Practice

This project helps to understand cloud infrastructure concepts by simulating a cloud environment.

Think of the setup as a neighborhood where everything works together to keep the community running smoothly, safely, and efficiently—just like a real cloud network, but all local.

./run_minio_pipeline.sh

This script will:

• Start and configure the MinIO Docker container
• Setup MinIO client alias and generate local CA certificates
• Create bucket and attach security policies
• Create users and service accounts with read/write policies
• Rotate access keys in batch
• Encrypt and upload a test file to MinIO storage

The Neighborhood (Virtual Cloud Network - VCN)

The Virtual Cloud Network (VCN) is the entire neighborhood—a safe, private area where all the houses (servers and services) live and talk to each other.

---

Streets (Subnets)

The neighborhood has different streets called subnets. Some are public where visitors can come freely, while others are private and hidden from outsiders.

---

Houses (Servers and Backend Sets)

• Web Server House:
  Shows visitors websites or applications.
• Backend Server Houses:
  Handle the work behind the scenes and process requests.
• Backend Set:
  A group of houses working together for specific jobs, like running events or chores collectively.

---

Gates and Doors (Gateways)

• Main Gate (Internet Gateway):
  The big gate where visitors arrive from the outside internet.
• Back Gate (NAT Gateway):
  A secret door letting private houses send mail outside but stays hidden from strangers.
• Magic Door (Service Gateway):
  Special door connecting only to trusted services within the neighborhood.

---

Guards and Maps

• Guards (Security Lists):
  Gatekeepers letting only trusted visitors into streets and houses.
• Neighborhood Map (Route Table):
  Guides visitors and mail to the right destinations.

---

Traffic Helpers

• Traffic Cop (Load Balancer):
  Directs visitors evenly to different houses to avoid overcrowding.
• Reception Desk (Listener):
  Welcomes visitors and tells the traffic cop what they want.

---

Deliveries and Addresses

• Address Book (CIDR Block):
  Lists house numbers so mail (data) knows where to go.
• Mail Carrier (DHCP Options):
  Gives each house its address and mail directions.

---

Safety and Access

• House Inspector (Health Check):
  Ensures each house is open and ready for visitors.
• Magical Keys (SSH Keys):
  Special keys to securely access and fix houses.

---

• Secret Tunnel (Site-to-Site VPN):
  Connects your neighborhood to another safe neighborhood for private visits.
• Traffic Cop Station Size (Shape):
  Determines how many visitors the traffic cop can manage simultaneously.
