Postgres: From Cloud to Hybrid and On Prem Again
summary
Claims that Postgres runs in Kubernetes with only a 1% storage penalty and a 5% OLTP penalty on bare-metal were validated by benchmarks comparing VM and bare-metal Kubernetes; the stack uses a CloudNativePG Kubernetes-native operator, leverages local PVs/LVM and logical replication for near-zero cutover (RDS → CloudNativePG), and reaches >1,000 TPS on one and a half cores in EKS. Project hits 4,500 GitHub stars and is resubmitted to the CNCF sandbox; EU Data Act portability is cited as a practical driver.
