According to [Harness’s FinOps in Focus 2025 report](https://www.prnewswire.com/news-releases/44-5-billion-in-infrastructure-cloud-waste-projected-for-2025-due-to-finops-and-developer-disconnect-finds-finops-in-focus-report-from-harness-302385580.html), an estimated 21% of enterprise cloud infrastructure spend – equivalent to $44.5 billion in 2025 – goes to underutilized resources. The same research found that the median compute instance runs at just 7–12% CPU utilization. The math is stark: enterprises are paying for roughly five to ten times the compute they actually use. Imagine if your annual database spend was $50,000. You could be wasting up to $40,000! Instant autoscaling Pay-as-you-go power ## Why Cloud Database Waste Happens ### 1. Provisioned for the Worst Case Engineering teams 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 Limits 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 leads to substantial waste. Traditional models charge for the instance size you reserve – not the compute you actually use. ## What True Serverless Really Means for Cloud Databases Not all “serverless” databases are equal. Here’s what genuine serverless architecture delivers: ### Scale to Zero – Truly MariaDB Cloud 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 An intelligent proxy keeps connections alive even when the database process pauses, so your application never knows the difference. ### No Trade-Offs on Compatibility MariaDB Cloud uses the unmodified open-source database engine, avoiding forks or fragmented re-architectures that can introduce unexpected behavior. ## The Business Case: How Much Can You Save? Most cloud databases run at 7–12% CPU utilization on average — but the bills don’t reflect that. Serverless databases flip the equation: buy **outcomes** instead of **capacity**. Moving from always-on clusters to on-demand scaling can eliminate 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. ## Start Building Today – For Free Ready to eliminate wasted cloud database spend?

Serverless cloud database pricing charges you only for the compute – CPU, memory, and I/O – your queries actually consume, billed per minute. Unlike traditional provisioned models, you are not charged for reserved instance capacity that sits idle. #### How much can serverless databases reduce cloud costs? Organizations moving from always-on provisioned clusters to serverless on-demand scaling can typically reduce database infrastructure costs by 70–90%, depending on their workload patterns. The biggest savings come from workloads with variable or spiky usage. #### What does “scale to zero” mean for a database? Scale to zero means a serverless database can reduce its resource footprint to effectively nothing during periods of inactivity – so you pay zero during idle time. When traffic arrives, the database scales back up instantly (in milliseconds) without any connection disruption for your application. #### How does MariaDB Cloud handle connections during scale-to-zero? MariaDB Cloud uses an intelligent proxy layer that maintains active client connections even while the underlying database process is paused or scaling. Applications experience no dropped connections or timeouts. #### What types of workloads benefit most from serverless databases? Serverless database architecture is ideal for workloads with unpredictable or spiky usage – development and staging environments, event-driven applications, SaaS products with variable tenant activity and AI/data applications that run in bursts. Steady, high-throughput workloads may benefit from a different provisioning model. #### Is there a free tier for MariaDB Cloud? Yes. MariaDB Cloud offers a free serverless developer tier — no credit card required. You can deploy a database, connect your application, and start querying immediately.
