Creation of Network & Subnet
We create networks & subnets in OCI to securely divide, control, and efficiently manage cloud resources and communication
🧠 Simple Idea
👉 VCN= Your private cloud network
👉 Subnets= Smaller sections inside that network
👉NAT= Network Address Translation is a service that allows private resources inside a VCN to access the public internet, without exposing them directly to the internet also its blocking all direct inbound internet access.
👉SG=Service Gateway is a VCN gateway that lets your private resources access Oracle services privately, without using the public internet
Without Service Gateway
Private VM → NAT / Internet Gateway → Internet → Object Storage
With Service Gateway
Private VM → Service Gateway → Oracle Services Network → Object Storage
