Serverless, cloud-native strongly consistent replicated state machine atop S3

Source: Dev.to

Overview

S2C is a novel implementation of distributed consensus and state machine replication built on top of shared storage (AWS S3). It can be embedded in any JVM‑based distributed application—such as microservices—to provide a strongly consistent medium for storing structured data (e.g., durable cache, key‑value store, distributed atomic counter).

Key Benefits

• Strong consistency without the need to maintain a majority of nodes.
• Quorum offloaded to S3, simplifying cluster management.
• Single‑node operation capable of surviving a full cluster crash.
• Storage and consensus combined in a single service (S3).

Implementation Details

• Implemented in Java (additional language support is planned).
