Build an Orchestrator in Go (From Scratch)


Book Description

Understand Kubernetes and other orchestration systems deeply by building your own using Go and the Docker API. In Build an Orchestrator in Go (From Scratch) you will learn how to: Identify the components that make up any orchestration system Schedule containers on to worker nodes Start and stop containers using the Docker API Manage a cluster of worker nodes using a simple API Work with algorithms taken from cutting-edge Google Borg research papers Demystify orchestration systems like Kubernetes and Nomad Orchestration systems like Kubernetes coordinate other software subsystems and services to create a complete organized system. Although orchestration tools have a reputation for complexity, they’re designed around few important patterns that apply across many aspects of software development. Build an Orchestrator in Go (From Scratch) reveals the inner workings of orchestration frameworks by guiding you as you design and implement your own using the Go SDK. As you create your own orchestration framework, you’ll improve your understanding of Kubernetes and its role in distributed system design. You’ll also build the skills required to design custom orchestration solutions for those times when an out-of-the-box solution isn’t a good fit. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the technology Orchestration systems provide the management framework for software and infrastructure that’s distributed across multiple machines and services. By managing the many individual components and containers in a large application, they ensure web apps are resilient and reliable, automatically switching between resources in response to crashes and outages. A properly designed orchestration system can seamlessly scale to handle traffic loads, and reduce time-consuming manual work for sysadmin and site reliability engineers. About the book Build an Orchestrator in Go (From Scratch) teaches you to implement an orchestrator from scratch. You’ll discover the components that make up all orchestration systems, and use the Docker API and Go SDK to build layers of functionality from tasks, to workers, to the manager. Learn how to save on costs by maximising the usage of a cluster, or spread tasks among workers to avoid overload and downtime. Once you’ve built your working system, you’ll even implement a command line user interface to easily manage your orchestrator. About the reader For software engineers, operations professionals, and SREs who are familiar with Docker and the basics of Go. About the author Tim Boring is a staff engineer at Golioth. He has twenty years of experience in technology organizations ranging from small business to global enterprises. His career spans roles in technical support to site reliability and software engineering. Tim is most interested in the design of software systems and distributed systems in particular.




Reactive Spring


Book Description

Microservices and big-data increasingly confront us with the limitations of traditional input/output. In traditional IO, work that is IO-bound dominates threads. This wouldn't be such a big deal if we could add more threads cheaply, but threads are expensive on the JVM, and most other platforms. Even if threads were cheap and infinitely scalable, we'd still be confronted with the faulty nature of networks. Things break, and they often do so in subtle, but non-exceptional ways. Traditional approaches to integration bury the faulty nature of networks behind overly simplifying abstractions. We need something better.Join Spring Developer Advocate Josh Long for an introduction to reactive programming in the Spring ecosystem, leveraging the reactive streams specification, Reactor, Spring Boot, Spring Cloud and so much more.This book will cover important concepts in reactive programming including project Reactor and the reactive streams specification, data access, web programming, RPC with protocols like RSocket, testing, and integration and composition, and more.




The Analytical Marketer


Book Description

How to lead the change Analytics are driving big changes, not only in what marketing departments do but in how they are organized, staffed, led, and run. Leaders are grappling with issues that range from building an analytically driven marketing organization and determining the kinds of structure and talent that are needed to leading interactions with IT, finance, and sales and creating a unified view of the customer. The Analytical Marketer provides critical insight into the changing marketing organization—digital, agile, and analytical—and the tools for reinventing it. Written by the head of global marketing for SAS, The Analytical Marketer is based on the author’s firsthand experience of transforming a marketing organization from “art” to “art and science.” Challenged and inspired by their company’s own analytics products, the SAS marketing team was forced to rethink itself in order to take advantage of the new capabilities that those tools offer the modern marketer. Key marketers and managers at SAS tell their stories alongside the author’s candid lessons learned as she led the marketing organization’s transformation. With additional examples from other leading companies, this book is a practical guide and set of best practices for creating a new marketing culture that thrives on and adds value through data and analytics.
