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 practicesPrinciples—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 systemsManagement—Explore Google's best practices for training, communication, and meetings that your organization can use
This new workbook not only combines practical examples from Google’s experiences, but also provides case studies from Google’s Cloud Platform customers who underwent this journey. Evernote, The Home Depot, The New York Times, and other companies outline hard-won experiences of what worked for them and what didn’t.
Dive into this workbook and learn how to flesh out your own SRE practice, no matter what size your company is.
You’ll learn:How to run reliable services in environments you don’t completely control—like cloudPractical applications of how to create, monitor, and run your services via Service Level ObjectivesHow to convert existing ops teams to SRE—including how to dig out of operational overloadMethods for starting SRE from either greenfield or brownfield
Network programming and automation will help you simplify tasks involved in configuring, managing, and operating network equipment, topologies, services, and connectivity. Through the course of the book, you’ll learn the basic skills and tools you need to make this critical transition.
This book covers:Python programming basics: data types, conditionals, loops, functions, classes, and modulesLinux fundamentals to provide the foundation you need on your network automation journeyData formats and models: JSON, XML, YAML, and YANG for networkingJinja templating and its applicability for creating network device configurationsThe role of application programming interfaces (APIs) in network automationSource control with Git to manage code changes during the automation processHow Ansible, Salt, and StackStorm open source automation tools can be used to automate network devicesKey tools and technologies required for a Continuous Integration (CI) pipeline in network operations
A book designed for SysAdmins, Operations staff, Developers and DevOps who are interested in deploying a log management solution using the open source Elasticsearch, Logstash & Kibana (ELK) stack.
In this book we will walk you through installing, deploying, managing and extending Logstash. We're going to do that by introducing you to Example.com, where you're going to start a new job as one of its SysAdmins. The first project you'll be in charge of is developing its new log management solution.
We'll teach you how to:
* Install and deploy Logstash.
* Ship events from a Logstash Shipper to a central Logstash server.
* Filter incoming events using a variety of techniques.
* Add structured logging to your applications.
* Output those events to a selection of useful destinations.
* Use Logstash's awesome web interface Kibana.
* Scale out your Logstash implementation as your environment grows.
* Quickly and easily extend Logstash to deliver additional functionality that you might need.
By the end of the book, you should have a functional and effective log management solution that you can deploy into your own environment.
Updated for Logstash and ELK 5.0.0!
Authors Lorin Hochstein and René Moser show you how to write playbooks (Ansible’s configuration management scripts), manage remote servers, and explore the tool’s real power: built-in declarative modules. You’ll discover that Ansible has the functionality you need—and the simplicity you desire.Manage Windows machines, and automate network device configurationManage your fleet from your web browser with Ansible TowerUnderstand how Ansible differs from other configuration management systemsUse the YAML file format to write your own playbooksWork with a complete example to deploy a non-trivial applicationDeploy applications to Amazon EC2 and other cloud platformsCreate Docker images and deploy Docker containers with Ansible
This book is best read start to finish, with later chapters building on earlier ones. Because it’s written in a tutorial style, you can follow along on your own machine. Most examples focus on web applications.
