In terms of orchestration, Nexedi stack surpasses other solutions in multiple aspects.
It is a self-hosted system, which means that the system can deploy the system. This is usually a sign of good design. It is also a convenient way to let developers improve and contribute to the system using the system.
It encapsulates what other solutions tend to implement in external software: monitoring, accounting, DR. This reduces the need for multiple or large teams since all aspects of service operation (build, configure, run, orchestrate, monitor, account, etc.) are defined in a single script, possibly by a single developer.
Its design is self-converging, which means that every node of a distributed system acts autonomously and tries to converge towards a target state define by the OSS/BSS master. This approach was inspired by Mark Brugess' theory of promises which also inspired CFEngine, a devops tool used at Facebook. It explains why Nexedi's stack is much more stable and resilient than open source alternatives which are not based on a self-converging model.
Nexedi's stack supports some advanced features such as shared services, hard real-time services and delegated services. Shared services are mandatory to implement edge services such as CDN or reduce the cost of certain cloud services such as database. Real-time services are mandatory for industrial edge applications.
Delegated services are necessary to support business models such as cloud federation or to optimise resource allocation for recursive deployments.
