Ubicloud eliminated our IOPS bottlenecks and is already saving us $300k a year, with $500k projected as we migrate more workloads.
Hatchet is a platform for running anything async; workflows, data pipelines, AI agents, and background jobs. Developers integrate Hatchet via its SDK, letting Hatchet’s orchestration layer handle execution outside the web server.Today, Hatchet runs over 100 million tasks per day and stores 15TB of data across its databases. At this scale, database performance and costs became a critical challenge.
One of Hatchet’s database shards routinely spiked past AWS RDS limits. To cope, they maxed out at 64,000 provisioned IOPS, but still faced bottlenecks.
“We would keep hitting the IOPS limit on RDS. We didn’t need 64k IOPS all the time, but AWS forced us to stay at that level—and the bill was just way too high.”
By moving to Ubicloud, Hatchet eliminated IOPS concerns entirely. NVMe-backed storage handled bursts effortlessly, and even during 10x traffic spikes the database continued to perform without alarms or queue build-ups.
At one point Hatchet needed to scale RDS storage from 1TB to 10TB. However, when the need subsided, AWS offered no easy way to scale down, leaving them stuck paying for capacity they no longer needed.
“It seems like such a simple feature, but once you provision storage in RDS it only goes up. We were paying way too much because we couldn’t scale back down.”
Ubicloud allows scaling storage down safely and with minimal downtime, giving Hatchet the flexibility to right-size their databases as workloads change and avoiding the waste of overprovisioned capacity.
Hatchet’s RDS costs had climbed to around $60k per month, largely from storage, networking, and provisioned IOPS. With Ubicloud, those costs have dropped to the mid-$20k range, cutting hundreds of thousands of dollars per year. This shift translates to over $300k in annual savings, with projections of nearly $500k once the remaining workloads are migrated.
Migrations often mean hours of disruption, but Hatchet transitioned to Ubicloud quickly and safely.
“We were able to migrate our core database with just five minutes of paused writes. Having rollback options and support from the Ubicloud team made it stress-free.”
Using logical replication, the core migration finished with only a few minutes of downtime, while rollback safeguards ensured no risk to production workloads. Ubicloud engineers also actively supported the migration and monitored the process end to end to ensure success.
Hatchet’s migration to Ubicloud produced immediate, quantifiable benefits:
