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.

External Service Gateway


Integrate with external systems by encapsulating the inbound and outbound inter-system communication within a bounded isolated component to provide an anti-corruption layer that acts as a bridge to exchange events between the systems.

Context, problem, and forces

Systems often need to integrate with an external system, such as Stripe for payment processing, SendGrid for transactional emails, AWS Cognito for user authentication, or a custom system. Our cloud-native systems are composed of bounded isolated components, which provide proper bulkheads to make the components responsive, resilient, and elastic. The isolation is achieved via asynchronous inter-component communication. We aim to eliminate all synchronous inter-component communication. External systems provide an Open API for inbound and outbound communication with other systems.

Integrating with an external system is inherently risky because they are typically owned by a third party and thus not within your...
