Introduction
Welcome! In this article series, we delve into the intricate process of designing and implementing a real-world network architecture. We’ll leverage our collective knowledge and practical experience to construct a robust networking infrastructure from the ground up.
Selecting Regions and Creating Compartments
Our journey begins with the crucial task of selecting regions for our network. For this demonstration, we’ll focus on Phoenix and Ashram regions. If you’re unfamiliar with region subscription, fret not, as we’ll guide you through the process seamlessly. Following region selection, we’ll establish a compartment to house all our network resources securely.
Building Virtual Client Networks
Next, we embark on creating virtual client networks (VCNs), employing both manual configuration and guided wizard setup. Within these VCNs, we’ll define availability domain-specific subnets and regional subnets while ensuring non-overlapping CIDR selections.
Establishing Connectivity
Connectivity forms the backbone of our architecture. We’ll interconnect VCNs via remote peering connections, facilitating communication between Oracle Services Network, on-premises infrastructure through FastConnect and VPN. Our architecture adopts a three-layer approach, with load balancers deployed at the web layer, backed by application and database layers.
Implementing Security Measures
Security remains paramount in our design. We’ll leverage Oracle Cloud Infrastructure DNS service, fortified with SSL certificates, and enforce web application firewall (WAF) policies to safeguard our domain. Additionally, we’ll deploy bastion services for secure access to private resources.
Leveraging Additional Resources
Our networking architecture extends beyond the basics. Compute instances serve as web servers and backend hosts, complemented by transaction processing and Autonomous Data Warehouse databases. Object storage buckets facilitate database backups, with replication ensuring redundancy across distant regions. VCN flow logs offer valuable insights into network traffic.
Configuration Phases
The implementation unfolds in structured phases. We commence with building the web and application layers in the Phoenix region, gradually expanding to include regional subnets and connectivity to Oracle Services Network. Each phase is meticulously executed, paving the way for a comprehensive network infrastructure.
Conclusion
In summary, our endeavor encompasses a holistic approach to network architecture, incorporating diverse components like VCNs, load balancers, and security protocols.
