Architecting Cloud Native Applications

By: Kamal Arora, Erik Farr, John Gilbert, Piyum Zonooz

Overview of this book

Cloud computing has proven to be the most revolutionary IT development since virtualization. Cloud native architectures give you the benefit of more flexibility over legacy systems. This Learning Path teaches you everything you need to know for designing industry-grade cloud applications and efficiently migrating your business to the cloud. It begins by exploring the basic patterns that turn your database inside out to achieve massive scalability. You’ll learn how to develop cloud native architectures using microservices and serverless computing as your design principles. Then, you’ll explore ways to continuously deliver production code by implementing continuous observability in production. In the concluding chapters, you’ll learn about various public cloud architectures ranging from AWS and Azure to the Google Cloud Platform, and understand the future trends and expectations of cloud providers. By the end of this Learning Path, you’ll have learned the techniques to adopt cloud native architectures that meet your business requirements. This Learning Path includes content from the following Packt products: • Cloud Native Development Patterns and Best Practices by John Gilbert • Cloud Native Architectures by Erik Farr et al.

Self-healing infrastructures


Another important paradigm to adopt for cloud-native applications as it relates to scalability and availability are self-healing infrastructures. A self-healing infrastructure is an inherently smart deployment that is automated to respond to known and common failures. Depending on the failure, the architecture is inherently resilient and takes appropriate measures to remediate the error.

The self-healing aspect can apply at the application, system, and hardware levels. The cloud has completely taken responsibility for "hardware self-healing". No such thing technically exists, as we have yet to figure out a way to repair broken hard disks, torched CPUs, or to replace burned-out RAM without human interaction. As cloud consumers, however, the current state of affairs mimics an idealistic future. CSPs deploy people behind the scenes to repair and replace failing hardware resources quickly and furtively. By our strict definition, we have yet to approach self-healing...
