Overview of this book

Digital transformation is the new paradigm in enterprises, but the big question remains: is the enterprise ready for transformation using native technology embedded in Agile/DevOps? With this book, you'll see how to design, implement, and integrate DevOps in the enterprise architecture while keeping the Ops team on board and remaining resilient. The focus of the book is not to introduce the hundreds of different tools that are available for implementing DevOps, but instead to show you how to create a successful DevOps architecture. This book provides an architectural overview of DevOps, AIOps, and DevSecOps – the three domains that drive and accelerate digital transformation. Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, this DevOps book will help you to successfully integrate DevOps into enterprise architecture. You'll learn what AIOps is and what value it can bring to an enterprise. Lastly, you will learn how to integrate security principles such as zero-trust and industry security frameworks into DevOps with DevSecOps. By the end of this DevOps book, you'll be able to develop robust DevOps architectures, know which toolsets you can use for your DevOps implementation, and have a deeper understanding of next-level DevOps by implementing Site Reliability Engineering (SRE).

Architecting SRE using KPIs

Before we dive into the definition of KPIs, we need to get back to the basic principles of SRE. SRE teams focus on reliability, scalability, availability, performance, efficiency, and response. These are all measurable items, so we can transform them into KPIs. In this section, we will learn how to do that using SLOs, Service-Level Indicators (SLIs), and the error budget.

The main KPIs that we use in SRE are as follows:

  • SLOs: In SRE, this is defined as how good a system should be. An SLO is much more precise than an SLA, which comprises a lot of different KPIs. You could also state that the SLA comprises a number of SLOs. However, an SLO is an agreement between the developers in the SRE team and the product owner of the service, whereas an SLA is an agreement between the service supplier and the end user.

    The SLO is a target value. For example, the web frontend should be able to handle hundreds of requests per minute. Don't make it too complex...
