Building REST APIs with Spring Boot and Spring Cloud
The document discusses building REST APIs using Spring Cloud and Spring Boot, focusing on cloud-native development, microservices, and deployments. It covers key concepts such as the twelve-factor applications methodology, service discovery, and the use of tools like Spring Cloud and Cloud Foundry for managing microservices. A demo is also mentioned, highlighting the deployment of Spring Boot containers on AWS using Lattice.

Twelve Factor Applications- http://12factor.net/ Use declarative formats for setup automation, to minimize time and cost for new developers joining the project; Have a clean contract with the underlying operating system, offering maximum portability between execution environments; Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration; Minimize divergence between development and production, enabling continuous deployment for maximum agility; And can scale up without significant changes to tooling, architecture, or development practices. 6
