🔌 Thomas Limoncelli is a well-known Site Reliability Engineer (SRE) who has worked at major tech companies including Google, Stack Overflow, and Bell Labs. 🏢 Data centers consume approximately 1% of global electricity, which is roughly equivalent to the power consumption of the entire country of Sweden. 📚 The book explains how modern data centers have evolved from telephone company Central Offices, which were the first large-scale facilities designed to house communications equipment. 🌡️ Modern data centers require precise temperature control - for every 1 watt of computing power, approximately 0.5-1 watts of cooling power is needed. 💻 The largest data centers in the world, known as "hyperscale" facilities, can house hundreds of thousands of servers and cover more than 1 million square feet of space.
