Fluid Storage: Forkable, Ephemeral, and Durable Infrastructure for the Age of Agents

Fluid Storage is a next-generation storage architecture designed to provide a forkable, ephemeral, and durable infrastructure, particularly for agent-driven environments. This innovative system operates as a distributed block layer, offering true elasticity, synchronous replication, and zero-copy forks, making it compatible with databases like PostgreSQL and others. Fluid Storage emerged as a solution to address the limitations of existing elastic storage systems, such as Amazon EBS, which often result in slow scaling and inefficiencies due to over-provisioning. It unifies elasticity, iteration, and durability within its architecture, allowing for instant forks and snapshots without incurring downtime or excessive costs. The system's multi-tenant design ensures high utilization and cost efficiency by billing based on actual consumption rather than allocated space. Fluid Storage's architecture comprises a distributed key-value block store, a storage proxy layer, and a user-space storage device driver, together providing seamless performance, fast recovery, and the ability to scale fluidly to meet the dynamic needs of modern agentic workloads. Tiger Cloud's free-tier databases now run on Fluid Storage, allowing developers to experience this fluid infrastructure firsthand, with opportunities for early-access partnerships for those developing agentic or infrastructure platforms.
