High Performance Browser Networking: What every web developer should know about networking and web performance
How prepared are you to build fast and efficient web applications? This eloquent book provides what every web developer should know about the network, from fundamental limitations that affect performance to major innovations for building even more powerful browser applications—including HTTP 2.0 and XHR improvements, Server-Sent Events (SSE), WebSocket, and WebRTC.
Author Ilya Grigorik, a web performance engineer at Google, demonstrates performance optimization best practices for TCP, UDP, and TLS protocols, and explains unique wireless and mobile network optimization requirements. You’ll then dive into performance characteristics of technologies such as HTTP 2.0, client-side network scripting with XHR, real-time streaming with SSE and WebSocket, and P2P communication with WebRTC.
- Deliver superlative TCP, UDP, and TLS performance
- Speed up network performance over 3G/4G mobile networks
- Develop fast and energy-efficient mobile applications
- Address bottlenecks in HTTP 1.x and other browser protocols
- Plan for and deliver the best HTTP 2.0 performance
- Enable efficient real-time streaming in the browser
- Create efficient peer-to-peer videoconferencing and low-latency applications with real-time WebRTC transports
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
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 →

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 →
Docker containers offer simpler, faster, and more robust methods for developing, distributing, and running software than previously available. With this hands-on guide, you’ll learn why containers are so important, what you’ll gain by adopting Docker, and how to make it part of your development process.
Ideal for developers, operations engineers, and system administrators—especially those keen to embrace a DevOps approach—Using Docker will take you from Docker and container basics to running dozens of containers on a multi-host system with networking and scheduling. The core of the book walks you through the steps needed to develop, test, and deploy a web application with Docker.

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.
