You build a complete cloud-native platform step by step, starting from establishing a solid IaaS foundation with OpenStack, understanding its architecture, deploying and validating virtual infrastructure, and designing accurate system diagrams. You then provision Kubernetes using Infrastructure as Code with Terraform, deepen core Kubernetes concepts, and evolve the setup into a real PaaS product with operators and custom resources. Afterwards, the platform is extended with RESTful APIs, a secure Web UI, observability, audit logging, and production-grade deployment, resulting in a coherent, end-to-end cloud platform architecture.
