Amazon Web Services (AWS) has expanded its Savings Plans portfolio by officially introducing the latest Database Savings Plans, a new flexible pricing model that can reduce managed database costs by up to 35%. This new offering extends the Savings Plans pricing model beyond compute and into AWS’s managed database ecosystem for the first time.
Until now, services like Amazon RDS, Aurora, DynamoDB, ElastiCache, and other managed database engines relied almost entirely on Reserved Instances, which forced customers to commit to specific instance types, engine versions, and Regions.
The reaction across the industry has been immediate and enthusiastic. At re:Invent, Database Savings Plans received some of the loudest applause of the keynote, reflecting how long customers have asked for a more adaptable commitment option for databases. Analysts and practitioners have echoed that sentiment, noting that this release removes many of the long-standing economic and operational barriers associated with Reserved Instances.
The shift is significant for engineering and FinOps teams too. This is the clearest signal yet that AWS is moving database commitments toward the same flexible model that transformed compute pricing in 2019.

AWS’s new Database Savings Plans introduce a spend-based discount model for managed databases. Instead of committing to a specific instance configuration, customers now commit to a fixed hourly spend for one year, and AWS automatically applies discounted rates to eligible database usage each hour.
This mirrors the pricing approach used for Compute Savings Plans and extends it to the database layer. The plan applies across both provisioned and serverless database usage, offering a more flexible alternative to the rigid, instance-specific structure of Reserved Instances.
In effect, Database Savings Plans include:
Database Savings Plans apply across a variety of AWS-managed database services, and the benefits are especially noticeable in environments that scale frequently, shift between deployment models, or evolve across instance generations. Workloads running on services like Amazon RDS, DynamoDB, or ElastiCache for Valkey gain predictable savings without being locked to a particular engine, instance family, or Region
For relational databases, this means teams can resize, migrate, or even switch to serverless deployments without losing coverage from their long-term commitments. For serverless and key-value workloads, applying spend-based discounts to on-demand and variable throughput provides savings where commitment options were previously limited. And for in-memory caching layers, being able to move across instance generations without breaking discounts reduces operational overhead and lowers the chances of unused commitments.
Together, these changes bring the pricing model much closer to how modern database environments actually operate. Afterall, these environments are constantly growing, shifting, and rarely stay tied to one configuration for long.
The shift from configuration-specific Reserved Instances to spend-based Database Savings Plans introduces several meaningful changes in how AWS applies discounts to managed database workloads. While Reserved Instances are tied to a specific engine, instance family, and Region, Database Savings Plans evaluate eligible usage continuously and apply discounts wherever they provide the most value within the customer’s committed hourly spend.
Database Savings Plans will apply automatically across eligible usage for the following AWS managed database services:
As AWS expands Regions, introduces new instance types, or updates these managed database offerings, the Savings Plans model will apply to newly supported usage as those capabilities become available.
Note: AWS’s announcement emphasizes support for current-generation instance families; customers should verify specific instance/engine eligibility in the AWS console or pricing pages before purchasing.
For more details, AWS recommends reviewing the Savings Plans User Guide.
For teams currently using RDS Reserved Instances, Database Savings Plans introduce a more flexible commitment option that better aligns with evolving workloads. Existing RIs will continue to function normally for the remainder of their term, so there is no immediate action required.
The same considerations apply to workloads running on services like DynamoDB or ElastiCache for Valkey, where usage patterns can shift due to scaling, throughput changes, or instance generation upgrades. In these cases, a spend-based commitment can provide more predictable coverage than configuration-specific RIs.
Deciding whether to transition from RIs to Database Savings Plans ultimately depends on each workload’s behavior and refresh cycle. Teams should evaluate how often their databases resize, change capacity modes, or shift deployment models, and determine whether a flexible, spend-based model aligns better with those patterns.
Overall, this announcement marks the beginning of a more adaptable commitment model for managed databases. Customers with expiring RIs now have an alternative that accommodates modern scaling strategies without being tied to a single configuration.
Database Savings Plans immediately expand the commitment surface area that Usage.ai can optimize. Up to now, database commitments were limited to configuration-specific Reserved Instances, which constrained how far automation could go for workloads that frequently shift engines, instance classes, or deployment models. With spend-based commitments now available across multiple managed database services, Usage.ai can apply the same automated coverage modeling and optimization logic used for compute Savings Plans directly to database environments.
From a technical standpoint, this gives Usage.ai customers a more adaptable commitment type for dynamic or multi-engine database footprints, and it reduces the operational overhead associated with tracking instance-specific commitments. It also enables cleaner transitions at RI expiration windows, where Usage.ai can now evaluate Database Savings Plans as an alternative path for maintaining or improving coverage.
Support for Database Savings Plans is currently being added to Usage.ai’s optimization engine. This will allow customers to evaluate and adopt this new commitment model as part of their existing coverage workflows. The update is scheduled to roll out in early January 2026.
