Although service-level objectives (SLOs) continue to grow in importance, there's a distinct lack of information about how to implement them. Practical advice that does exist usually assumes that your team already has the infrastructure, tooling, and culture in place. In this book, recognized SLO expert Alex Hidalgo explains how to build an SLO culture from the ground up. Ideal as a primer and daily reference for anyone creating both the culture and tooling necessary for SLO-based approaches to reliability, this guide provides detailed analysis of advanced SLO and service-level indicator (SLI) techniques. Armed with mathematical models and statistical knowledge to help you get the most out of an SLO-based approach, you'll learn how to build systems capable of measuring meaningful SLIs with buy-in across all departments of your organization. Define SLIs that meaningfully measure the reliability of a service from a user's perspective Choose appropriate SLO targets, including how to perform statistical and probabilistic analysis Use error budgets to help your team have better discussions and make better data-driven decisions Build supportive tooling and resources required for an SLO-based approach Use SLO data to present meaningful reports to leadership and your users

Trail of Footprints offers an intimate glimpse into the commission, circulation, and use of indigenous maps from colonial Mexico. A collection of sixty largely unpublished maps from the late sixteenth to the eighteenth centuries and made in the southern region of Oaxaca anchors an analysis of the way ethnically diverse societies produced knowledge in colonial settings. Mapmaking, proposes Hidalgo, formed part of an epistemological shift tied to the negotiation of land and natural resources between the region's Spanish, Indian, and mixed-race communities. The craft of making maps drew from social memory, indigenous and European conceptions of space and ritual, and Spanish legal practices designed to adjust spatial boundaries in the New World. Indigenous mapmaking brought together a distinct coalition of social actors-Indian leaders, native towns, notaries, surveyors, judges, artisans, merchants, muleteers, collectors, and painters-who participated in the critical observation of the region's geographic features. Demand for maps reconfigured technologies associated with the making of colorants, adhesives, and paper that drew from Indian botany and experimentation, trans-Atlantic commerce, and Iberian notarial culture. The maps in this study reflect a regional perspective associated with Oaxaca's decentralized organization, its strategic position amidst a network of important trade routes that linked central Mexico to Central America, and the ruggedness and diversity of its physical landscape.
