Simple Log Service uses a three-replica mechanism to ensure high data reliability.
The underlying storage system of Simple Log Service uses a three-replica mechanism to ensure high data reliability. Three replicas are provided for all data. Then, the replicas are stored in different servers of a cluster by using a specific distributed storage algorithm. This way, the storage system ensures that three data replicas are distributed to different physical disks on different servers. If a single hardware device fails, it does not cause data loss. The data in the three replicas remains consistent.
