"Netdata Cloud utilizes Netdata agents as a distributed database, combining their collective power into a dynamic, powerful and infinitely scalable database for monitoring. This decentralization and collective utilization of resources that are already available and spare, allows Netdata to scale way better than any other monitoring solution, at a fraction of the cost.
Centralization points (Netdata Parents utilizing the streaming feature) for high availability and to support ephemeral configurations like Kubernetes, are supported with Netdata. But unlike other solutions, Netdata does not require just one centralization point. Users can have as many as needed, and Netdata Cloud can seamlessly combine all available centralization points to one distributed database. Recently this functionality has been improved significantly, by adding active-active clustering and replication."
