Stop Paying for Air: Most Cloud Database Spend Is Wasted

April 23, 2025

The Hidden Cost of Idle Databases

Structured databases are the single biggest line item in enterprise IT infrastructure. IDC put this category of spend at $7.2 billion in just the last six months of 2023. At the same time, most cloud infrastructure is barely used—Datadog reports that 83% of container spend goes to idle resources. Put the two together, and it’s obvious: underutilized databases are one of the most expensive, large-scale sources of waste in the cloud.

Why it happens

1. Provisioned for the worst case

Engineering teams still size cloud databases for Black Friday traffic, then leave that allocation running 24 × 7. Over‑provisioning is the default when you don’t have true real-time auto‑scaling.

2. Pay-for-capacity models have their place, but often at a cost

Provisioned cloud databases can be a reasonable choice for steady, predictable workloads. But for anything with spiky or unpredictable usage, paying for peak capacity 24/7 can lead to substantial waste. Traditional models charge for the instance size you reserve, not the compute you actually use.

What True Serverless Really Means

Scale to zero—truly
- SkySQL serverless databases scale all the way down to micro-instances with zero idle cost, unlike many “serverless” offerings that keep charging for parked capacity.
Per-minute billing
- You’re only billed for the exact CPU, memory, and I/O your queries consume, not for the instance size you reserved.
Launch in milliseconds
- Serverless databases provision instantly, with caches automatically hydrated on wake-up… no timeouts.
Real-time auto-scaling
- Compute and storage scale in real time with full resource isolation, never shared across tenants.
Always-on client experience
- Our intelligent proxy keeps connections alive even when the database process pauses, so your app never knows the difference.
No trade-offs on compatibility
- SkySQL uses the unmodified open-source database engine, avoiding forks or fragmented rearchitectures that can introduce unexpected behavior.

The bottom line

Most cloud databases average single-digit CPU utilization, but the bills don’t. Serverless databases flip the equation: buy outcomes instead of capacity. Moving from always‑on clusters to on‑demand scaling can wipe out 70‑90 % of the cost tied up in “just‑in‑case” headroom, without compromising peak‑time performance.

It’s time to stop paying for air. Let your database sleep when you do, and watch the cloud bill follow suit.
