Implementing Service Level Objectives

Alex Hidalgo is a Site Reliability Engineer and expert at all things related to Service Level Objectives. He developed an interest in computers at a young age, started writing his first BASIC programs at around the age of nine, and remembers the Internet when it was all still text. He eventually turned his hobby into a career, working in various capacities as a network engineer, security engineer, and systems administrator and in many roles within the world of IT support. After moving to New York, he joined Admeld as a Technical Operations Engineer, only to find himself employed by Google a few months later due to acquisition.

At Google, Alex was first introduced to the discipline of Site Reliability Engineering, which connected so closely with him that he wonders how he ever did anything else. Eventually, he found his other calling as an educator, writer, and speaker, traveling all over the world training other Site Reliability Engineers, becoming one of the primary developers of the Coursera Google IT Professional Certification, and contributing to multiple chapters of The Site Reliability Workbook – most notably “Implementing SLOs” and “SLO Engineering Case Studies.”

Recently, he has joined Squarespace, where his focus is now on spreading the concepts of SLO-based approaches to service reliability – both internally and across the entire industry. When not sharing his passion for error budgets with others, you can find him scuba diving or watching college basketball. He lives in Park Slope, Brooklyn, with his partner Jen and a rescue dog named Taco. He thinks about SLOs so much he once had a dream about defining some for Taco.
