On the World Wide Web, speed and efficiency are vital. Users have little patience for slow web pages, while network administrators want to make the most of their available bandwidth. A properly designed web cache reduces network traffic and improves access times to popular web sites--a boon to network administrators and web users alike.Web Caching hands you all the technical information you need to design, deploy, and operate an effective web caching service. It starts with the basics of how web caching works, from the HTTP headers that govern cachability to cache validation and replacement algorithms.Topics covered in this book include:

The book also covers the important political aspects of web caching, including privacy, intellectual property, and security issues.Internet service providers, large corporations, or educational institutions--in short, any network that provides connectivity to a wide variety of users--can reap enormous benefit from running a well-tuned web caching service. Web Caching shows you how to do it right.
Scalability Rules is the easy-to-use scalability primer and reference for every architect, developer, web professional, and manager. Authors Martin L. Abbott and Michael T. Fisher have helped scale more than 200 hypergrowth Internet sites through their consulting practice. Now, drawing on their unsurpassed experience, they present 50 clear, proven scalability rules–and practical guidance for applying them.
Abbott and Fisher transform scalability from a “black art” to a set of realistic, technology-agnostic best practices for supporting hypergrowth in nearly any environment, including both frontend and backend systems.
For architects, they offer powerful new insights for creating and evaluating designs. For developers, they share specific techniques for handling everything from databases to state. For managers, they provide invaluable help in goal-setting, decision-making, and interacting with technical teams. Whatever your role, you’ll find practical risk/benefit guidance for setting priorities–and getting maximum “bang for the buck.”

Learning Agile is a comprehensive guide to the most popular agile methods, written in a light and engaging style that makes it easy for you to learn.
Agile has revolutionized the way teams approach software development, but with dozens of agile methodologies to choose from, the decision to "go agile" can be tricky. This practical book helps you sort it out, first by grounding you in agile's underlying principles, then by describing four specific--and well-used--agile methods: Scrum, extreme programming (XP), Lean, and Kanban.
Each method focuses on a different area of development, but they all aim to change your team's mindset--from individuals who simply follow a plan to a cohesive group that makes decisions together. Whether you're considering agile for the first time, or trying it again, you'll learn how to choose a method that best fits your team and your company.
Docker is quickly changing the way that organizations are deploying software at scale.

Legend has it that Google deploys over a billion application containers a week. How is that possible? The company decided to share the process through an open source project called Kubernetes, which replicates many of the features found in its internal system. This practical book will prepare you to take advantage of everything the Kubernetes platform has to offer.
Rather than an exact copy of its internal Borg system, Kubernetes is an upgrade based on lessons Google learned over the last decade. Kubernetes is also designed to integrate with the most robust container ecosystem: Docker. Developers and Ops practitioners can easily deploy a demo Kubernetes environment and kick the tires, but when it comes time to scale to hundreds of nodes, you’re going to need a reliable field guide.
Kubernetes: Up and Running will help you:
- Learn how to make zero down-time application deployments with Kubernetes
- Track metrics and logs for every container running in your cluster
- Discover patterns for running large-scale application deployments that work for big players such as Google, Twitter, and Facebook
- Explore topics including Kubernetes components (kubelet, API, scheduler, replication controllers); containers; distributed computing; service discovery; and continuous delivery More info →
This practical guide addresses technical, cultural, and managerial challenges of implementing and maintaining a DevOps culture by describing failures and successes. Authors Katherine Daniels and Jennifer Davis provide with actionable strategies you can use to engineer sustainable changes in your environment regardless of your level within your organization.
- Individual collaboration: Changes to help people get work done, get along with others, and avoid burnout
- Team affinity: New patterns and styles for working together, with real-world case studies for different organizational sizes and types
- Tools: Different types of tools, their uses cases, and things to consider when choosing or developing them
- Devops at scale: Strategies for taking what works and scaling it up, as well as common pitfalls that can happen when working in any large organization
This book explains how to take advantage of technologies like cloud, virtualization, and configuration automation to manage IT infrastructure using tools and practices from software development. These technologies have decoupled infrastructure from the underlying hardware, turning it into data and code. "Infrastructure as Code" has emerged alongside the DevOps movement as a label for approaches that merge concepts like source control systems, Test Driven Development (TDD) and Continuous Integration (CI) with infrastructure management.
Virtualization and cloud make it easy to rapidly expand the size of infrastructure, but the habits and practices we used in the past with hardware-based infrastructure don't keep up. Teams end up with hundreds of servers, all a bit different, and find themselves unable to fully automate their infrastructure.
The book will go through the challenges and problems created by all these wonderful new tools, and the principles and mindset changes that a team needs to make to use them effectively. It describes patterns, practices, and ideas that have been adopted from software development, especially Agile concepts, and brought into the IT Ops world as part of the DevOps movement. These ways of working have been proven in many organizations, including well known names like Netflix, Amazon, and Etsy, and also in more established organizations including publishers, banks, and even the British government.More info →
As web applications grow, two things begin to happen. They become significantly more complicated and hence brittle, and they handle significantly larger traffic volume requiring more novel and complicated mechanisms to handle this traffic. This can lead to a death spiral for an application that can lead to brownouts, blackouts, and other quality of service and availability problems.
This book helps you avoid this death spiral by teaching you basic techniques for building applications that can reliably handle huge quantities of traffic, as well as huge variability in traffic without impacting the quality your customers expect.
You’ll learn about:
Service Oriented Architectures, including services and microservices, for building distributed systems that are more resilient to localized failures
Building systems with failures in mind to help you develop robust designs and systems emerge that reduce brittleness and result in higher availability
Forward-looking risk management for identifying system problems
Scaling your engineering team to build and manage web applications that scale successfully
Monitoring and responsiveness to quickly identify problems when your application begins to act abnormally
