Nothing has changed the way software is designed and developed in the IT world in recent years as much as microservices. Modern applications must operate within a cluster of multiple nodes, be dynamically deployable, scalable, and fault-tolerant.
Microservices form the foundation of cloud-native applications. Each microservice is independent and can run on multiple servers at different locations. Cloud-native applications leverage these loosely coupled cloud services. Cloud-native is an approach designed to ensure that applications are developed for cloud computing architecture. The characteristics of cloud computing architecture are used to the application’s advantage, maximizing all available opportunities. This type of application is often abbreviated as NCA, which stands for Native Cloud Application.
NCAs offer numerous benefits. They are not tied to specific hardware or operating systems, are easily scalable, simple to deploy, and geo-redundant. “Redundancy” means having at least one additional resource as a backup for emergencies. Combined with “geo,” it means that these resources are also spatially separated. This ensures that even in the event of severe technical issues at one location, an intact backup is available at another location.
