Infrastructure in Oracle Cloud (OCI)

To create a fault-tolerant environment, the Infrastructure as Code (IaC) approach is used. The entire resource management process is automated using Terraform.

Infrastructure Diagram

Key Components:

  • Terraform: Reads .tf files and creates resources in OCI (VCN, subnets, OKE cluster).
  • VCN (Virtual Cloud Network): Creates an isolated cloud environment containing the subnets.
  • Subnets: Divide access — a public subnet for the cluster API and a private one for the worker nodes.
  • OKE Cluster & Node Pool: Managed Kubernetes and worker servers (Worker Nodes).
  • Traefik & Load Balancer: The Traefik Helm chart automatically requests Oracle to create an external load balancer.
