Amazon Kinesis Information Streams is a serverless streaming knowledge service that helps you seize, course of, and retailer streaming knowledge at any scale. On November 4, 2025, Amazon Kinesis Information Streams launched On-demand Benefit mode, a functionality that permits on-demand streams to deal with prompt throughput will increase at scale and value optimization for constant streaming workloads. Traditionally, you had to decide on between provisioned mode, which required managing stream capability, and on-demand mode, which mechanically scaled capability, however this new providing removes the necessity to consider stream sort in any respect.
On this publish, we present three real-world eventualities evaluating totally different utilization patterns and exhibit how On-demand Benefit mode can optimize your streaming prices whereas sustaining efficiency and suppleness. To have a significant comparability, we ran simulations in two separate AWS accounts: one with On-demand Customary mode and one other with On-demand Benefit mode enabled on the account degree. Each deployments maintained equivalent stream configurations, shard allocations, and ingest patterns, offering a comparability of the billing affect for the entire following eventualities.
All costs displayed on this publish are from the us-east-1 Area.
Breaking down On-demand Benefit financial savings
Now let’s go into extra particulars. Within the first publish, we talked in regards to the heat throughput characteristic and the way you should utilize it to heat streams to deal with gigabytes or hundreds of thousands of information per second with On-demand Benefit mode. Subsequent, we illustrate how totally different streaming use instances function most price effectively with the On-demand Benefit mode, whereas sustaining efficiency and suppleness.
Enabling On-demand Benefit mode within the account degree provides you price financial savings throughout many dimensions in comparison with On-demand Customary, listed below are some notable ones:
- Offers at the least 60% financial savings by committing to an account to stream at the least 25 MiBps utilization within the AWS Area. The minimal dedication is about $100 a day based mostly on AWS N. Virginia Areas’ public pricing.
- Enhanced Fan Out shoppers utilization is priced 68% decrease and you may have as much as 50 per stream, in comparison with 20 per stream with out On-demand Benefit.
- Prolonged retention utilization is priced 77% decrease when utilizing knowledge storage past 24 hours.
- No minimal per-stream mounted cost, so you should utilize as many streams as you want with out incurring a better price.
Why select Kinesis On-demand Benefit: 60%+ financial savings
We evaluated Amazon Kinesis Information Streams On-demand utilizing each Customary and Benefit modes by deploying 10 streams and producing a sustained ingest throughput of 100 MiBps throughout all streams. This situation fashions an ecommerce firm streaming person clickstream knowledge to generate real-time insights. The simulation was run over two days in two separate AWS accounts with the totally different modes. On day one, we maintained a gentle ingestion price of 100 MiBps. On day two, in anticipation of a vacation gross sales occasion, we elevated the nice and cozy throughput capability by 10X throughout all 10 streams whereas holding the precise ingest price fixed at 100 MiBps. Every stream is ingesting 10 MiBps with a complete of 100 MiBps throughout all On-demand streams.
On the second day, we enabled heat throughput of 100 MiBps in an account with On-demand Benefit mode configured. With heat throughput, you’ll be able to proactively pre-scale your streams when anticipating a site visitors surge.

This use case is price efficient in On-demand Benefit due to the constant knowledge throughput site visitors and the necessity to use a number of streams. You may see zero stream hour expenses in Benefit mode however in On-demand Customary mode there’s a $0.04 cost per stream hour. Moreover, the incoming bytes cost for Benefit mode is $0.032 per GB and On-demand Customary is $0.08 per GB. The On-demand Customary configuration generated complete prices of $2,071.75 over the 48-hour interval, which comes out to $1,037 per day, which is $378,505 yearly. The equivalent workload working with On-demand Benefit mode prices $823.44 for a similar 48-hour interval, roughly $412 per day leading to an annual price of $150,380. There may be additionally no extra price for heat throughput in On-demand Benefit. This interprets to a 60% price discount, which implies annual financial savings of $228,125 for this single workload.
State of affairs 2: 15 MiBps throughput and prolonged retention throughout 10 streams in a single account
A healthcare firm requires a two-day knowledge retention interval to make sure steady replay-ability, and regulatory necessities mandate that various kinds of knowledge be saved in separate streams. To emulate this situation, we deployed 10 Amazon Kinesis Information Streams configured in each On-demand Customary and Benefit modes, every with an prolonged 48-hour retention interval. The prolonged retention permits downstream techniques to reprocess knowledge and get well from transient failures. This use case can be anticipated to be cost-efficient in On-demand Benefit mode because of the want for a number of streams and retention, some extent we discover additional within the following price breakdown picture.
We generated constant ingest site visitors of 15 MiBps distributed throughout 10 streams for 48 hours to judge prices. On-demand Customary Mode:
On-demand Benefit Mode enabled:
The Value Explorer screenshot provides us a side-by-side view of the pricing between On-demand Customary and Benefit modes. On-demand Customary got here out to a every day price of $176, yearly changing into $64,240. For On-demand Benefit, the every day price was $104 with an annual price of $37,960. In consequence, we obtain a 41% financial savings with Benefit mode regardless of working with 15 MiBps throughput and implementing prolonged retention. Customary mode has a further price of $0.10 per GB of knowledge saved past 24 hours, as much as 7 days. Benefit mode prices a further $0.023 per GB month (past 24 hours, as much as 12 months) leading to price optimization for knowledge storage. This situation reveals how Benefit mode delivers price advantages throughout a broader vary of workloads. When enabling Benefit mode, you decide to paying for utilization at a minimal of 25 MiBps. Nonetheless, in our simulation with 15 MiBps throughput, we discovered that clients nonetheless achieved vital price financial savings. With Benefit mode, so long as you’re ingesting 10 MiBps or extra, you’ll expertise decrease prices in comparison with Customary mode, even when committing to the 25 MiBps threshold.
State of affairs 3: 1 Kinesis Information Stream with 10 enhanced fan-out shoppers
In a microservices structure, a number of companies may have to learn from the identical knowledge stream concurrently and with low latency. Because the system evolves, extra Enhanced Fan-Out (EFO) shoppers may be added to help new analytics use instances and derive deeper insights from the streaming knowledge pipeline.
Subsequent, we consider the associated fee comparability of utilizing EFO shoppers with On-demand Benefit mode in a microservices structure. Over a 24-hour interval, we examined a single Amazon Kinesis Information Stream with commonplace 24-hour retention, linked to 10 AWS Lambda features configured as EFO shoppers.
To evaluate the associated fee affect of a number of EFO shoppers accessing the identical stream concurrently, we generated a constant ingest price of 25 MiBps all through the analysis interval. The next chart reveals a Kinesis Information Stream with Enhanced Fan-Out Customers with 25MiBps payload.
The next charts present the associated fee distinction between On-demand Customary mode vs On-demand Benefit mode enabled:
Our Value Explorer evaluation demonstrates that even with a number of EFO shoppers, the On-demand Benefit mode resulted in decrease total prices in comparison with the On-demand Customary mode. The On-demand Customary price was $1,266 whereas the Benefit mode price was $419. For a similar workload traits, we noticed roughly 67% financial savings with annual financial savings of $309,155. That is particularly necessary for organizations constructing event-driven architectures the place a number of companies want impartial, real-time entry to streaming knowledge. Enhanced fanout knowledge retrievals are $0.016 per GB per shopper in Benefit mode in comparison with the $0.05 of Customary mode. Now that we’ve mentioned which workloads we advocate for Kinesis On-demand Benefit, let’s flip to workloads that we advocate for On-demand Customary mode. Extremely spiky, unpredictable workloads with low sustained throughput (underneath 10 MiBps) are advisable candidates for On-demand Customary. With these workloads, clients can let the stream mechanically scale throughput capability with out committing to a constant throughput utilization.
On-demand Benefit in comparison with Provisioned mode:
With each On-demand Customary and On-demand Benefit modes obtainable, clients not have to depend on Provisioned mode. As a substitute of constantly managing capability to stability efficiency and value, on-demand streams supply a streamlined pricing mannequin and higher ease of use. Moreover, clients working provisioned workloads that function many streams or use options resembling Prolonged Retention and Enhanced Fan-Out ought to strongly take into account migrating to On-demand Benefit. Information streams use the identical underlying infrastructure, no matter which mode you select, so there is no such thing as a distinction in availability or reliability between On-demand Benefit and provisioned.
- For guaranteeing streams can help prompt scaling at no additional price and may reactively scale when wanted, On-demand Benefit is a greater match than Provisioned mode, as a result of heat throughput doesn’t incur a further price.
- Even at a big scale (Gbps), On-demand Benefit’s pay-for-actual-data-usage billing is aggressive.
- On-demand Benefit has a a lot decrease price to make use of EFO (for prime fanout wants like microservices) and Prolonged Retention.
That can assist you examine, you should utilize the Kinesis console to examine in case your account’s prime 200 provisioned streams are a superb match to make use of On-demand Benefit as a substitute.
