Many organizations today orchestrate and maintain apps that rely on other people's services. Software designers, developers, and architects in those companies often work to coordinate and maintain apps based on existing microservices, including third-party services that run outside their ecosystem. This cookbook provides proven recipes to help you get those many disparate parts to work together in your network.Author Mike Amundsen provides step-by-step solutions for finding, connecting, and maintaining applications designed and built by people outside the organization. Whether you're working on human-centric mobile apps or creating high-powered machine-to-machine solutions, this guide shows you the rules, routines, commands, and protocols--the glue--that integrates individual microservices so they can function together in a safe, scalable, and reliable way.Design and build individual microservices that can successfully interact on the open webIncrease interoperability by designing services that share a common understandingBuild client applications that can adapt to evolving services without breakingCreate resilient and reliable microservices that support peer-to-peer interactions on the webUse web-based service registries to support runtime "e;find-and-bind"e; operations that manage external dependencies in real timeImplement stable workflows to accomplish complex, multiservice tasks consistently

A lot of work is required to release an API, but the effort doesnt always pay off. Overplanning before an API matures is a wasted investment, while underplanning can lead to disaster. This practical guide provides maturity models for individual APIs and multi-API landscapes to help you invest the right human and company resources for the right maturity level at the right time.How do you balance the desire for agility and speed with the need for robust and scalable operations? Four experts from the API Academy show software architects, program directors, and product owners how to maximize the value of their APIs by managing them as products through a continuous life cycle.Learn which API decisions you need to govern and how and where to do soDesign, deploy, and manage APIs using an API-as-a-product (AaaP) approachExamine ten pillars that form the foundation of API product workLearn how the continuous improvement model governs changes throughout an APIs lifetimeExplore the five stages of a complete API product life cycleDelve into team roles needed to design, build, and maintain your APIsLearn how to manage your API landscapethe set of APIs published by your organization

Powerful web-based REST and hypermedia-style APIs are becoming more common every day, but instead of applying the same techniques and patterns to hypermedia clients, many developers rely on custom client code. With this practical guide, youll learn how to move from one-off implementations to general-purpose client apps that are stable, flexible, and reusable.Author Mike Amundsen provides extensive background, easy-to-follow examples, illustrative dialogues, and clear recommendations for building effective hypermedia-based client applications. Along the way, youll learn how to harness many of the basic principles that underpin the Web.Convert HTML-only web apps into a JSON API serviceOvercome the challenges of maintaining plain JSON-style client appsDecouple the output format from the internal object model with the representor patternExplore client apps built with HALHypertext Application LanguageTackle reusable clients with the Request, Parse, Wait Loop (RPW) patternLearn the pros and cons of building client apps with the Siren content typeDeal with API versioning by adopting a change-over-time aestheticCompare how JSON, HAL, Siren, and Collection+JSON clients handle the Objects/Addresses/Actions ChallengeCraft a single client application that can consume multiple services

The popularity of REST in recent years has led to tremendous growth in almost-RESTful APIs that dont include many of the architectures benefits. With this practical guide, youll learn what it takes to design usable REST APIs that evolve over time. By focusing on solutions that cross a variety of domains, this book shows you how to create powerful and secure applications, using the tools designed for the worlds most successful distributed computing system: the World Wide Web.Youll explore the concepts behind REST, learn different strategies for creating hypermedia-based APIs, and then put everything together with a step-by-step guide to designing a RESTful Web API.Examine API design strategies, including the collection pattern and pure hypermediaUnderstand how hypermedia ties representations together into a coherent APIDiscover how XMDP and ALPS profile formats can help you meet the Web API "e;semantic challenge"e;Learn close to two-dozen standardized hypermedia data formatsApply best practices for using HTTP in API implementationsCreate Web APIs with the JSON-LD standard and other the Linked Data approachesUnderstand the CoAP protocol for using REST in embedded systems

With this concise book, youll learn the art of building hypermedia APIs that dont simply run on the Web, but that actually exist in the Web. Youll start with the general principles and technologies behind this architectural approach, and then dive hands-on into three fully-functional API examples.Too many APIs rely on concepts rooted in desktop and local area network patterns that dont scale wellcostly solutions that are difficult to maintain over time. This book shows system architects and web developers how to design and implement human- and machine-readable web services that remain stable and flexible as they scale.Learn the H-Factors for representing application metadata across all media types and formatsUnderstand the four basic design elements for authoring hypermedia typesConvert a simple read-only XML-based media type into a successful API designExamine the challenges and advantages of designing a hypermedia type with JSONUse HTML5s rich set of hypermedia controls in the API design processLearn the details of documenting, publishing, and registering media type designs and link-relation types

Microservices can have a positive impact on your enterprisejust ask Amazon and Netflixbut you can fall into many traps if you dont approach them in the right way. This practical guide covers the entire microservices landscape, including the principles, technologies, and methodologies of this unique, modular style of system building. Youll learn about the experiences of organizations around the globe that have successfully adopted microservices.In three parts, this book explains how these services work and what it means to build an application the Microservices Way. Youll explore a design-based approach to microservice architecture with guidance for implementing various elements. And youll get a set of recipes and practices for meeting practical, organizational, and cultural challenges to microservice adoption.Learn how microservices can help you drive business objectivesExamine the principles, practices, and culture that define microservice architecturesExplore a model for creating complex systems and a design process for building a microservice architectureLearn the fundamental design concepts for individual microservicesDelve into the operational elements of a microservices architecture, including containers and service discoveryDiscover how to handle the challenges of introducing microservice architecture in your organization

APIs are transforming the business world at an increasing pace. Gain the essential skills needed to quickly design, build, and deploy quality web APIs that are robust, reliable, and resilient. Go from initial design through prototyping and implementation to deployment of mission-critical APIs for your organization.
