The article discusses the native tools offered by major cloud providers for ETL (Extract, Transform, Load) processes. It categorizes these tools into four types: code-based ETL, GUI-based ETL, workflow-based ETL, and automated ELT. Each tool is evaluated based on its purpose, limitations, and ideal use cases within the context of Amazon Web Services (AWS), Google Cloud Platform, and Microsoft Azure. The article also introduces Fivetran as an alternative solution for ongoing, maintenance-free data replication. A summary chart at the end compares these tools across different categories.
