🌐 Introduction to VPC in Nuvion

📘 Introduction​

The VPC (Virtual Private Cloud) is a private virtual network created within the cloud, allowing you to have full control over your network infrastructure, as if you were inside your own datacenter.

With the VPC, it is possible to isolate environments, control traffic, create subnets, and define security rules, ensuring greater protection and organization of your resources.

🧠 Simplified Concept​

Imagine the cloud as a large corporate building.
The VPC would be your exclusive floor within this building, where only your company has access.

Inside it, you can:

✅ Create private networks
✅ Define internal IPs
✅ Control who can access
✅ Publish services securely
✅ Separate environments (production, staging, and development)

🏗️ How does it work in Nuvion?​

In the Nuvion solution, the VPC is formed by several components that work together:

  • 🌐 Virtual Networks (Networks) → Environment segmentation
  • 🔀 Subnets → IP organization
  • 🚦 Virtual Routers → Internal and external communication
  • 🔐 Security Groups → Access control
  • 🌍 Floating IPs → Secure service exposure
  • ⚖️ Load Balancers → High availability

🧩 Basic Architecture​

Example of a common VPC:

Internet
   │
   ▼
Router (SNAT)
   │
   ├── Subnet Frontend (10.10.1.0/24)
   │
   ├── Subnet Backend (10.10.2.0/24)
   │
   └── Subnet Database (10.10.3.0/24)

This separation increases security and facilitates scalability.

🔐 Security and Isolation​

Each VPC is isolated from others within the cloud. This guarantees:

  • No access between clients
  • Protection against unauthorized traffic
  • Control of data ingress and egress
  • Segmentation of critical services

Additionally, external access is done in a controlled way, using:

  • Floating IP
  • Load Balancer
  • Firewall rules

🚀 Main Benefits​

✔ Security​

Private environments protected against external access.

✔ Scalability​

Create and increase resources according to demand.

✔ High availability​

Integration with load balancers and multiple zones.

✔ Network control​

Complete definition of IP, subnets, and rules.

✔ Organization​

Clear separation between environments and applications.

📌 When to use a VPC?​

The VPC is recommended for:

  • Production systems
  • Critical applications
  • Multi-tier environments
  • Public APIs
  • Private databases
  • Microservices

🧪 Real use example​

A modern web application usually uses:

  • Public frontend
  • Private backend
  • Isolated database

The VPC allows only the frontend to be accessible, protecting the other services.

⚠️ Best practices​

✔ Plan IP blocks before creation
✔ Separate networks by environment
✔ Use NAT and SNAT correctly
✔ Never expose databases directly
✔ Always use Security Groups
✔ Document your architecture

🎯 Summary​

The VPC in SaveInCloud Nuvion is the foundation to build secure, scalable, and organized environments in the cloud.

It allows creating complete private networks, ensuring full control over communication, security, and internet access.
