Coordination of distributed systems leads to boiler plate patterns, and using Spring Cloud developers can quickly stand up services and applications that implement those patterns.They will work well in any distributed environment, including the developer’s own laptop, bare metal data centres, and managed platforms such as Cloud Foundry.Cloud Native is a style of application development that encourages easy adoption of best practices in the areas of continuous delivery and value-driven development.Every context in the hierarchy can also (in principle) have a different and hence a different remote property source if there is a Config Server.
