Nothing has changed the way software is designed and developed in the IT world in recent years as much as microservices. Today’s applications must function in a cluster of multiple nodes, dynamically be placeable, scalable and fault-tolerant.

Microservices, in turn, form the basis of cloud native applications. The individual microservices are independent of each other and can run on multiple servers at different locations. Cloud native applications use these loosely coupled cloud services. Cloud native is an approach that aims to ensure that applications are designed and developed for the cloud computing architecture. The specifics of the cloud computing architecture are to be used to the advantage of applications and make full use of all the possibilities. The abbreviation NCA, which stands for Native Cloud Application, is often used for this type of application.

NCAs have numerous advantages.They are not tied to any specific hardware or operating systems, are easy to scale, are easy to deploy, and they are geo-redundant. “Redundancy” means that you have at least one additional resource as a backup in case of an emergency. In combination with “Geo” means that these resources are also spatially separated from each other. This is the only way to really ensure that even if there are serious technical problems in one location, an intact backup is still available in another location.
