ELT vs K8s
ELT (Extract, Load, Transform) and K8s (Kubernetes) both come up in technology conversations and get confused. Here's the plain-English difference, side by side, so you can use each one with confidence.
The key difference: ELT refers to extract, load, transform, while K8s refers to kubernetes — they describe different things even when they show up in the same sentence.
ELT — Extract, Load, Transform
Modern variant where raw data is loaded into the warehouse first and transformed in-place using SQL. ELT is the cloud-warehouse default — cheaper storage, more flexible modeling.
K8s — Kubernetes
Open-source platform for orchestrating containerized workloads across a cluster of machines. K8s is the de facto standard for running production services at scale — and a real operational tax if you don't need that scale.
When to use ELT
