Oracle Cloud Infrastructure Network Diagram
Creating a network diagram for Oracle Cloud Infrastructure (OCI) involves mapping out various components that interact with each other. The main components generally include:
- Virtual Cloud Network (VCN): The VCN is your own private network within OCI. It provides isolation and segmentation for your cloud resources.
- Subnets: Within a VCN, you can have one or more subnets. Subnets can be either public or private.
- Internet Gateway: Allows resources in a VCN to access the internet. Only necessary for public subnets.
- NAT Gateway: Allows resources in a private subnet to access the internet without exposing them to the internet.
- Service Gateway: Provides a path for private network traffic between your VCN and supported Oracle services like Object Storage.
- Dynamic Routing Gateway (DRG): Connects the VCN to your on-premises network via VPN or other connectivity options.
- Local Peering Gateway (LPG): Allows peering between VCNs within the same Oracle Cloud region.
- Remote Peering Gateway (RPG): Allows peering between VCNs in different Oracle Cloud regions.
- Route Tables: Defines rules for routing traffic originating from all or a subset of resources in a VCN.
- Security Lists: Sets of inbound and outbound rules that apply to instances in a given subnet.
- Network Load Balancer (NLB) or Load Balancer (LB): Distributes incoming traffic across multiple targets, such as virtual machines (VMs).
Here’s a textual representation of what such a diagram might look like:
