Which company started the Site Reliability Engineering (SRE) movement?

Site Reliability Engineering (SRE) was born at Google in 2003, much before the DevOps movement. In 2003, a software engineer team took a mission to make Google’s already large-scale sites more reliable, efficient, and scalable.

The practices they developed responded so well to Google’s needs. Over a period, other big tech companies, such as Netflix, Twitter & Amazon, also adopted them and brought new techniques to the table.
