With the arrival of cloud computing, data no longer needs to be processed on local servers with limited scalability. This has allowed the paradigm of Extract, Transform & Load (ETL) to shift more toward Extract, Load & Transform (ELT), which is arguably simpler to work with due to all data being extracted and loaded into a data warehouse, where it is then subsequently transformed.
