RDS Rightsizing That's Actually Safe to Act On
Most teams avoid resizing production databases — the risk feels too high and the analysis too complex. Sedai continuously analyzes your RDS fleet and applies rightsizing changes automatically, using maintenance windows and incremental adjustments to keep risk minimal.
Nobody Touches a Production Database That's Working.
RDS handles the operational overhead of running a managed database, but the resource decisions that drive cost and performance still belong to your team. Instance sizing, storage configuration, and replica strategy are all difficult to revisit safely once a database is carrying real production traffic.
Instances get provisioned for peak load and stay there.
Rightsizing a production database means accepting regression risk on a system with high blast radius and slow recovery. Most teams make the rational choice to leave it alone — and pay for unused headroom indefinitely.
Storage configuration involves tradeoffs that aren't obvious at provisioning time.
Volume type, allocated size, and provisioned IOPS interact in ways that affect both performance and cost. Getting the combination wrong means overpaying for throughput or hitting I/O constraints that degrade query performance.
Idle infrastructure compounds quietly in the background.
Dev and staging instances running outside business hours, read replicas with minimal traffic, databases for deprioritized projects — these accumulate across accounts without triggering alerts. The cost shows up in the bill; the cause rarely surfaces without a dedicated audit.
How We Help
Instance Rightsizing
Sedai analyzes utilization at the 95th percentile to identify the optimal instance type and applies changes automatically during scheduled maintenance windows to minimize production risk.
Storage Optimization
Sedai evaluates volume type, size, and provisioned IOPS against actual usage — recommending the storage configuration that meets performance requirements at the lowest cost.
Unused Resource Cleanup
Sedai identifies inactive RDS instances and read replicas with no traffic, flagging them for decommissioning before they quietly accumulate months of unnecessary spend.
