DynamoDB provisioned vs on-demand cost: what teams should review
Compare DynamoDB provisioned and on-demand cost considerations and how Dynasight helps identify tables that deserve capacity review.
Short answer
Provisioned and on-demand DynamoDB capacity modes fit different traffic patterns. Dynasight helps teams identify tables whose capacity mode or provisioned settings may no longer match real workload behavior.
- Find provisioned capacity drift.
- Review traffic predictability before changing modes.
- Prioritize capacity conversations with table context.
Provisioned capacity can drift
A table can be provisioned for a launch, migration, or traffic spike and keep that headroom after the workload normalizes.
On-demand is not automatically cheaper
On-demand capacity can be operationally simple, but cost depends on workload shape, predictability, and traffic volume.
How Dynasight helps
Dynasight surfaces tables that deserve capacity-mode review and right-sizing discussions.
FAQ
Common questions
Should every DynamoDB table use on-demand?
No. The right choice depends on traffic predictability, cost goals, and operational preference.
What is overprovisioned capacity?
Provisioned read or write capacity that exceeds what the workload needs over a meaningful period.
Can Dynasight switch capacity modes?
No. Dynasight identifies candidates for review; your team controls changes.
