Sky Computing takes a different approach, automating placement and embracing workload mobility across clouds rather than forcing platform portability. Sat, 08 Nov 2025 00:00:00 GMT https://www.ronnyunger.com/blog/sky-computing-introduction Sky Computing reframes the cloud as a global marketplace instead of a set of isolated providers, enabling automatic workload placement across clouds through a broker. Early research and tools show meaningful gains in cost, availability, and flexibility — pointing toward a more open and portable compute ecosystem. Sun, 02 Nov 2025 00:00:00 GMT https://www.ronnyunger.com/blog/terraform-pulumi-crossplane Terraform, Pulumi, and Crossplane take different approaches to IaC — declarative, programmable, and Kubernetes-native. Understanding where each excels helps platform teams combine them effectively across base and service infrastructure.
