Since the emergence of cloud computing service level objectives (SLOs) and service level agreements (SLAs) have put themselves forward as one of the key enablers for cloud's on-demand, pay-as-you-go service consumption model. To date, the vast majority of cloud platforms provide support for SLAs only in terms of statically predefined SLOs, e.g., service availability, and low-level resource capacity guarantees, e.g., CPU usage. Unfortunately, there is only limited support to clearly map workload performance requirements to the resource capacity guarantees. In this article, we introduce SLOC— a novel elasticity framework, which promotes a novel performance-driven, SLO-native approach to cloud computing. We outline the main research challenges, vision, and approach of our SLOC framework toward the SLO-native paradigm in next generation cloud computing.

SLOC：下一代云计算的服务水平目标

自云计算服务水平目标 (SLO) 和服务水平协议 (SLA) 出现以来，它们已成为云按需、即用即付服务消费模式的关键推动因素之一。迄今为止，绝大多数云平台仅在静态预定义的 SLO（例如服务可用性）和低级别资源容量保证（例如 CPU 使用率）方面提供对 SLA 的支持。不幸的是，只有有限的支持才能将工作负载性能要求明确映射到资源容量保证。在本文中，我们将介绍 SLOC——一种新颖的弹性框架，它促进了一种新颖的性能驱动、SLO 原生云计算方法。我们概述了主要的研究挑战、愿景、
