What's the answer to today's increasingly complex applications? Micro-frontends. Inspired by the microservices model, this approach lets you break interfaces into separate features managed by different teams of developers. In this updated second edition, software architects, tech leads, and software developers will learn how to design, build, and deploy independent micro-frontends that compose unique frontend systems. Author Luca Mezzalira, principal serverless specialist solutions architect at AWS, shows you how micro-frontends enable agility within an organization, decentralize decision-making, and optimize for fast flow. This gives your organization technical flexibility and allows you to hire and retain a broad spectrum of talent. Micro-frontends also support distributed or colocated teams more efficiently. Pick up this book and learn how to get started with this technological breakthrough right away. In the long run, companies with large monoliths usually slow down all the operations needed to release any new feature, losing the great momentum they had at the beginning of a project where everything was easier and smaller with few complications and risks. Also, with monolithic applications, we have to test and deploy the entire codebase every single time, which comes with a higher chance of breaking the APIs in production, introducing new bugs, and making more mistakes, especially when the codebase is not rock solid or extensively tested. Solving these and many other challenges its staff faces, a company might move from complex monolith codebases to multiple smaller codebases and scoped domains called microservices.
