OCI Networking Best Practices for Beginners

Introduction Designing cloud networks requires careful planning and the use of proven best practices. Oracle Cloud Infrastructure (OCI) provides a powerful set of networking tools that allow engineers to build secure, scalable, and reliable cloud architectures. Best Practices Use Private Subnets for Sensitive Resources Critical services such as databases and internal applications should be placed in private subnets to limit direct internet exposure and improve security. Apply Multiple Security Layers Combining security lists and network security groups (NSGs) helps create stronger protection by controlling traffic at both the subnet and resource levels. Use Clear Naming Conventions Consistent and descriptive naming for networks, subnets, and gateways makes environments easier to manage and troubleshoot. Plan CIDR Blocks Carefully Proper CIDR planning prevents overlapping IP ranges and ensures your network can scale as infrastructure grows. Conclusion Following these networking best pra
