SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the complexities and potential pitfalls in Oracle Cloud Infrastructure (OCI) networking, providing expert guidance to prevent costly mistakes and optimize network design and security.

Core Features & Use Cases

Cost Optimization: Learn to leverage Service Gateways for free OCI service access and compare VPN vs. FastConnect costs.
Design Best Practices: Understand VCN CIDR planning, subnet sizing, and avoid common anti-patterns.
Security Guidance: Differentiate between Security Lists and Network Security Groups (NSGs) and when to use each.
Troubleshooting: Gain insights into VCN peering limitations and Load Balancer subnet requirements.
Use Case: Design a secure and cost-effective VCN architecture for a multi-tier application, ensuring optimal routing and security group configurations.

Quick Start

Use the networking-management skill to understand the cost savings of using a Service Gateway for Object Storage access.

FAQPage Schema

How do I design a secure multi-tier VCN architecture in OCI?▼

OCI Security Lists are stateful and apply to an entire subnet, while Network Security Groups (NSGs) provide granular, stateful rules applied to specific VNICs. Use NSGs for precise multi-tier application control and Security Lists for broad subnet perimeter defense.

What is the best way to optimize OCI networking costs for Object Storage access?▼

Use FastConnect for dedicated, private bandwidth with consistent performance, or a VPN for encrypted public internet tunnels. FastConnect suits high-throughput enterprise needs, while VPN provides lower-cost, quick connectivity for smaller workloads.

Why does VCN peering have routing limitations and how do I avoid them?▼

VCN peering limitations prevent transit routing, meaning peered VCNs cannot route traffic through each other to reach a third network. Avoid this by designing non-overlapping CIDRs and using a DRG for complex multi-VCN topologies.

What subnet sizing requirements exist for OCI Load Balancers?▼

OCI Load Balancers require a dedicated regional subnet with sufficient IP addresses for provisioning. Avoid subnet sizing pitfalls by allocating enough spare IPs to handle load balancer scaling and high-availability failovers within your VCN.
