Author Cornelia Davis likes to say that "the cloud" is more about how you design your applications than where you deploy them. Cloud Native: Designing Change-tolerant Software is your guide to developing strong applications that thrive in the dynamic, distributed, virtual world of the cloud. This book presents a mental model for cloud-native applications, along with the patterns, practices, and tooling that sets them apart. In it, you'll find realistic examples and expert advice for working with apps, data, services, routing, and more.

"Great introduction material that provides answers to all questions that come up when getting involved into cloud native development."

~ Gregor Zurowski

About the Technology

We are amid a radical change in how we design and build applications. With cloud platforms like AWS, Azure, and Google Cloud, even small teams can take full advantage of web-scale distributed application patterns and practice. Users and customers have higher expectations for reliability, availability, and performance. Cloud-native software promises near-zero downtime, shortened feedback cycles, multi-device support, and improved cost control. All this means developers need to learn new skills and techniques, along with a new way of thinking about application design.

What's inside

  • The application lifecycle of Cloud Native apps
  • Automated configuration management
  • Multi-tenant services, versioned services, and parallel deploys
  • Understanding Cloud Native Routing
  • Managing dependencies between apps and services

About the reader

Requires intermediate programming skill with Java or a similar language. Some experience with server-side development is helpful.
