Juicecloud

Juicecloud is a fictional cloud computing platform used in technical writings and education to illustrate cloud-native concepts. It is not an actual product or service, but a stand-in for discussing architecture, deployment, and operations of scalable applications.

The imagined Juicecloud provides core cloud services, including container orchestration, storage abstraction, service discovery, and an API-driven control plane. It supports declarative configuration via manifests and a command-line interface.

The design is described as a distributed system with a control plane that schedules workloads and maintains cluster state, and a data plane of nodes running workload agents. Components commonly depicted include an API server, scheduler, etcd-like store, and networking proxy. It emphasizes multi-tenant isolation and role-based access control.

In tutorials, Juicecloud is used to demonstrate deployment of microservices across nodes, rolling updates, and resource quotas. Because it is fictional, references vary by author, with some focusing on energy efficiency, others on developer experience.
