<ul><li>Cloud logging system proposed using Hyperledger for real-time and secure logs without compromising performance or cost.</li><li>Architecture and Workflow: Cloud server generates logs → Logs are sent to Pub/Sub for processing → Critical logs hashed and stored in Hyperledger for tamper-proof storage → Non-critical logs sent to traditional logging for storage.</li><li>Advantages: 1) Speed and real-time performance with low latency. 2) Logs are tamper-proof and cryptographically secured using Hyperledger. 3) Fault tolerance and high availability with Pub/Sub buffering and Redis replication. 4) Scalability through horizontal scaling of Redis and adding more Hyperledger peers. 5) Unified monitoring with Grafana for centralized monitoring across all components. 6) Compliance and regulatory value for industries needing immutable logs.</li><li>Drawbacks: 1) High complexity due to multiple components. 2) Blockchain latency may affect real-time responsiveness. 3) Hyperledger storage costs at scale. 4) Limited scalability of Hyperledger. 5) Pub/Sub introduces message handling complexity.</li></ul>
