Site Reliability Engineering


Book Description

The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use

The Complete Guide to IT Service Level Agreements


Book Description

Most suppliers lose around 16% of their customers each year. The reason? Poor service — whether perceived or real. Any technology-based support service, whether in-house, contracted or outsourced, stands to be accused of being insensitive to the requirements of its customers (or users). Equally, customers of a support service may have unrealistic expectations of what can be reasonably provided. Service Level Agreements (SLAs) can overcome these gulfs. A Service Level Agreement can create harmony between parties and can prevent disputes between customers and suppliers. It can justify investment and identify the "right" quality of service. It can mean the difference between business success and failure. SLAs are potentially a strategic tool to align all support services (particularly IT) directly to business mission achievement. In the past, few organizations used them in this way. Armed with this book and the companion SLA FRAMEWORK, more and more businesses are now succeeding. Where are SLAs going? Increasingly business-focused. Increasingly measured in real-time. Simple documents that cover complex service infrastructures. Providing a competitive edge. Embracing penalties. The brave, who commit to tight SLAs and perform against them will win the commercial spoils. This book provides the knowledge and tools based on fifteen years of intensive development to ensure your enterprise is among the winners.

Service Level Management in Cloud Computing


Book Description

Melanie Holloway explores a cloud broker offering service level agreement negotiation and monitoring as a service to consumers. She proposes a negotiation mechanism, which enables the achievement of economically efficient agreements, and an approach for reliable consumer side availability monitoring in conjunction with strategies for robust monitor placement. The author addresses the loss of control of consumers over critical aspects, specifically quality of service, when using services from the cloud.Basically, the cloud computing paradigm places the responsibility for resource management on the provider side. Hence, the control over cloud service performance is very limited on the consumer side.
