Object Storage Simulator — Interactive System Design Lab
Simulate the full object storage lifecycle: split a file into chunks, watch each chunk distribute across storage nodes spread across three availability zones, and observe the replication factor in action. Take a node offline and watch automatic repair kick in — the missing replica is reconstructed on a surviving node in the same AZ to restore the configured durability guarantee.
Upload a file, watch it chunk and replicate across storage nodes, then kill a node to see durability hold.
This free interactive simulation runs directly in your browser — no account needed. Adjust the parameters and watch how the system responds in real time.
