Comprehensive Overview of AWS DynamoDB Throughput Units - Certbolt

Amazon DynamoDB plays a pivotal role in delivering high-performance NoSQL database services within the AWS ecosystem. It supports a multitude of serverless applications by offering seamless scalability, low latency, and flexible capacity management. A fundamental part of mastering DynamoDB lies in grasping how read and write operations are quantified and how they influence overall expenditure. This is where Read Capacity Units (RCUs) and Write Capacity Units (WCUs) come into play, and understanding them is crucial for architects and developers who aim to optimize both performance and cost.

Comparing DynamoDB’s Provisioned and On-Demand Capacity Modes

Amazon DynamoDB offers two distinct capacity allocation models—Provisioned and On-Demand—each tailored to accommodate varying workload demands and usage scenarios. These modes are instrumental in determining both the throughput provisioning strategy and the cost structure for applications leveraging DynamoDB for fast, scalable, and serverless data storage.

In the On-Demand capacity mode, users are billed based on the precise number of read and write operations their applications execute. There’s no prerequisite for estimating or reserving throughput in advance. Instead, the database automatically adjusts to the traffic volume in real time. This makes On-Demand ideal for workloads with erratic or unpredictable patterns where sudden spikes or troughs are frequent. The consumption-based pricing model ensures that users only pay for what they utilize, allowing seamless elasticity without manual intervention.

Conversely, the Provisioned capacity mode involves defining throughput limits in advance. Users explicitly allocate Read Capacity Units (RCUs) and Write Capacity Units (WCUs) according to expected application demand. Although this approach offers finer control over spending and performance optimization, it introduces constraints. If the demand surpasses the pre-allocated throughput and auto-scaling isn’t enabled or misconfigured, throttling ensues. This can lead to increased latency or rejected requests. Provisioned capacity, however, shines in environments where access patterns are stable, repetitive, and forecastable, allowing architects to finely tune performance parameters and achieve cost-efficiency at scale.

Understanding the nuances between these two modes is essential for making informed infrastructure decisions, especially when aiming for scalability and cost containment in production systems.

An In-Depth Look at Read Throughput in On-Demand Mode

When operating under On-Demand capacity, Read Request Units (RRUs) form the backbone of how DynamoDB quantifies read consumption. Each type of read operation—strongly consistent, eventually consistent, or transactional—has a distinct RRU cost depending on the size of the item being accessed.

A single RRU supports one strongly consistent read per second for an item sized up to 4 KB. This means if you fetch an item that is 3.5 KB in size with strong consistency, it consumes exactly one RRU.

On the other hand, two eventually consistent reads for items up to 4 KB each can be performed using just one RRU. This is because eventually consistent reads are less resource-intensive, offering a trade-off by tolerating slightly stale data for improved throughput efficiency.

Transactional reads, being more stringent in terms of data integrity and durability, consume two RRUs per read operation for items up to 4 KB. These reads guarantee atomicity and isolation across operations, hence their higher RRU footprint.

If an item surpasses 4 KB, the RRUs are computed by dividing the item size by 4 KB and rounding up to the nearest integer. For instance, reading an 8.5 KB item with strong consistency would require 3 RRUs (8.5 / 4 = 2.125, rounded up to 3).

This dynamic model of read consumption enables applications to flexibly scale without the need to guess traffic volume, mitigating the risks associated with either over-provisioning or under-provisioning.

Evaluating Write Capacity in On-Demand Mode

Similar to RRUs, Write Request Units (WRUs) dictate how write throughput is calculated. For On-Demand mode, the metric system remains straightforward and adaptive.

A single WRU is enough to support one standard write operation per second for an item up to 1 KB in size. If the item size increases, the WRUs are calculated by dividing the size by 1 KB and rounding up. For instance, writing an item of 2.5 KB would consume 3 WRUs (2.5 / 1 = 2.5, rounded up to 3).

Transactional write operations, known for offering ACID compliance, demand twice the WRUs. Hence, inserting or updating an item of 1 KB within a transactional context would require 2 WRUs. Similarly, a transactional write involving a 2 KB item would consume 4 WRUs.

The On-Demand mode takes away the complexity of throughput estimation, automating the scaling process and adapting seamlessly to fluctuations in write demand. This makes it particularly appealing for applications with erratic or seasonal data entry rates.

Understanding Provisioned Capacity and How It Is Configured

In Provisioned mode, you must allocate throughput limits explicitly by defining how many RCUs and WCUs are required based on anticipated usage. This configuration offers strategic cost control but also necessitates ongoing monitoring and occasional adjustment.

Each Read Capacity Unit allows:

One strongly consistent read per second for an item up to 4 KB.
Two eventually consistent reads per second for items of the same size.
One transactional read per second consumes two RCUs for up to 4 KB.

For Write Capacity Units:

One WCU supports one standard write per second for a 1 KB item.
Two WCUs are needed for one transactional write per second for the same item size.

You are billed for the entire provisioned capacity whether it is fully utilized or not. If your actual usage stays below the allocated limits, the unused capacity remains idle but still incurs charges.

This model works optimally when the application experiences consistent traffic or where predictable usage patterns make provisioning simpler. Auto-scaling can be enabled to expand or contract provisioned throughput based on specific metrics or schedules, thus introducing elasticity while retaining cost predictability.

Scenarios Where On-Demand Capacity Is Most Beneficial

Choosing the On-Demand mode is advantageous in a wide range of dynamic application environments. Some of the best use cases include:

Development and testing phases, where workloads are experimental or lack predictability.
Startups or new applications, where traffic patterns are not yet established.
Spiky workloads, such as promotional events, ticketing systems, or live data feeds, where request volume can vary drastically in short bursts.
Data lake indexes and analytics queries, where access is intermittent and non-uniform.

On-Demand capacity is also useful when administrative overhead needs to be minimized, or when teams prefer not to engage in constant monitoring and capacity tweaking.

Ideal Scenarios for Provisioned Capacity

Provisioned capacity excels when workloads exhibit regular, steady traffic patterns. Typical use cases include:

Mature applications with stable traffic metrics and minimal fluctuations.
Enterprise systems that must maintain fixed service-level expectations and optimized budgets.
IoT telemetry data ingestion, where device reporting intervals are predictable.
Retail inventory systems, where traffic spikes are limited to seasonal changes that can be forecasted.

Provisioned mode is often paired with auto-scaling to accommodate gradual growth or occasional bursts while maintaining a degree of control over the maximum spend and baseline performance.

Monitoring and Performance Optimization Strategies

Regardless of the mode selected, tracking resource consumption and performance metrics is imperative. Amazon CloudWatch provides detailed insights into read and write throughput, throttling events, and latency. This data can be leveraged to fine-tune configurations and improve application responsiveness.

For Provisioned mode, setting up auto-scaling policies can help reduce the risk of over-provisioning or request throttling. In On-Demand mode, while scaling is automatic, monitoring usage can still reveal inefficiencies or areas for optimization.

To further optimize costs, developers may also implement conditional writes, sparse indexes, or partition key design strategies to reduce the overall load on DynamoDB.

Balancing Cost and Performance in DynamoDB Capacity Planning

Determining the most suitable capacity mode often hinges on balancing performance requirements with budget constraints. On-Demand mode provides simplicity, elasticity, and operational ease at a marginally higher per-request cost. Provisioned mode, though potentially more cost-effective in the long run, requires diligent oversight and periodic recalibration.

In some cases, hybrid strategies may be applied, such as initially deploying in On-Demand mode and switching to Provisioned once traffic stabilizes. AWS also allows mode switching (with certain limitations), providing a degree of flexibility as business requirements evolve.

Decoding Read Capacity Units in DynamoDB’s Provisioned Mode

In the realm of Amazon DynamoDB, understanding how capacity units function is vital for designing scalable and cost-efficient applications. Provisioned Mode in DynamoDB provides granular control over resource allocation, making it suitable for environments with predictable workloads. Within this configuration, read operations are governed by what are known as Read Capacity Units (RCUs), an important metric that directly influences the read throughput performance of your table.

A single Read Capacity Unit is defined as the ability to perform one strongly consistent read operation per second for an item of up to 4 KB in size. If your data access patterns do not require strict consistency, the same unit can alternatively handle two eventually consistent read requests per second for items up to 4 KB. For those utilizing transactional reads, which offer guaranteed atomicity and isolation, two RCUs are required for each 4 KB read operation per second.

In cases where data items exceed the 4 KB threshold, the RCU requirement scales accordingly. The formula to calculate the number of RCUs required is based on dividing the item size by 4 KB and rounding up to the nearest whole number. For example, reading an 8 KB item using strong consistency would demand 2 RCUs.

The strategic advantage of using Provisioned Mode becomes most apparent in applications with stable or forecastable access patterns. For instance, if your system typically sees a consistent level of read operations during business hours, allocating a fixed number of RCUs can lead to significant cost optimization. This predefined resource planning allows for fine-tuned performance control while minimizing unexpected overages or throttling.

Furthermore, RCUs also play a pivotal role in the way indexes perform. When Global Secondary Indexes are configured on a table, each indexed attribute that participates in read operations draws from a distinct RCU pool, necessitating careful capacity planning across both tables and indexes.

By mastering how read capacity scales with item size and consistency requirements, developers can architect highly responsive data layers that adapt fluidly to business needs. This flexibility, paired with the deterministic nature of Provisioned Mode, makes it a compelling choice for mission-critical systems where performance predictability is paramount.

Evaluating Write Operations in DynamoDB’s On-Demand Mode

On-Demand Mode in DynamoDB offers a radically different operational philosophy compared to Provisioned Mode. Rather than requiring users to predefine the expected workload, On-Demand Mode automatically adjusts capacity in real time, scaling to match incoming traffic without any manual intervention. This elasticity makes it ideal for applications with volatile, spiky, or unpredictable usage patterns.

At the core of On-Demand write processing is the concept of Write Request Units (WRUs). A single WRU allows one standard write operation per second for an item up to 1 KB in size. If the write operation involves a transactional request—providing enhanced consistency and integrity guarantees—then two WRUs are consumed for each 1 KB write.

When data payloads exceed the 1 KB threshold, the WRU calculation adjusts accordingly. For example, writing a 2.5 KB item in a standard write operation would require 3 WRUs, since the total size is divided by 1 KB and rounded up to the nearest whole unit. Similarly, transactional writes of the same size would consume 6 WRUs.

What makes On-Demand Mode especially valuable is its capacity to handle traffic spikes with no pre-configuration. Whether your application receives a sudden surge of users or experiences uneven write demands throughout the day, DynamoDB autonomously adapts to ensure performance remains consistent. This dynamic scaling eliminates the complexity of capacity planning and reduces the risk of throttled writes during high-traffic events.

The pricing model for On-Demand writes is usage-based, making it cost-effective for applications that experience irregular load or that are still evolving. Startups, event-driven platforms, and workloads with uncertain growth trajectories benefit significantly from this model, as it supports experimentation and flexibility without incurring the overhead of capacity forecasting.

Moreover, On-Demand Mode simplifies integration with serverless architectures. For example, AWS Lambda functions that write to DynamoDB tables can benefit from On-Demand provisioning since the traffic pattern generated by these functions is often unpredictable. By eliminating the need for manual scaling adjustments, developers can focus on writing business logic instead of managing throughput settings.

By leveraging On-Demand Mode, teams can unlock unmatched scalability while retaining operational simplicity. It is particularly effective in environments that demand agile resource allocation and high availability without the burden of constant infrastructure oversight.

Contrasting Provisioned and On-Demand Modes: Strategic Implications

When deciding between Provisioned and On-Demand modes, it is important to analyze the nuances of each model. Provisioned Mode grants precise control over capacity and can offer cost savings when workloads are well understood and consistent. In contrast, On-Demand Mode delivers unparalleled adaptability, making it the preferred option for workloads with highly variable or unpredictable access patterns.

Provisioned Mode is best suited for applications with consistent traffic levels, where historical data can guide future provisioning needs. Batch-processing systems, predictable business applications, and regulated data pipelines are examples where Provisioned Mode shines. Developers can allocate just enough capacity to meet demand, preventing unnecessary expenditure while ensuring dependable performance.

On the other hand, On-Demand Mode is tailored for innovation and agility. It supports rapid prototyping, seasonal spikes, and workloads that cannot be easily forecasted. In such use cases, it protects against performance degradation during usage surges and eliminates the risk of under-provisioning.

Furthermore, these modes can be interchanged. DynamoDB allows switching from Provisioned to On-Demand Mode and vice versa, offering hybrid deployment strategies for organizations looking to optimize costs and performance simultaneously. For instance, an e-commerce platform may use Provisioned Mode during regular operations and switch to On-Demand Mode during promotional campaigns or high-traffic sales periods.

Ultimately, the choice between the two depends on how predictable your workload is and how much flexibility you need. A thoughtful selection enables better resource management, consistent application performance, and smarter financial planning.

Capacity Units and Indexes: The Overlooked Connection

An often-misunderstood aspect of capacity unit planning is the role of secondary indexes. When you configure Local or Global Secondary Indexes (LSIs and GSIs), these indexes consume read and write capacity independently of the base table. This means that each read or write to an index is charged separately and must be accounted for when planning capacity.

In Provisioned Mode, you must provision additional RCUs and WRUs specifically for the indexes, depending on how frequently they are queried or updated. This adds a layer of complexity but also allows for tailored optimization. In On-Demand Mode, the index scaling follows the same auto-adjustment logic as the table, simplifying operations.

Regardless of mode, monitoring index utilization using Amazon CloudWatch is crucial. Unused or underutilized indexes contribute to capacity drain and unnecessary costs. Eliminating redundant indexes or fine-tuning access patterns can greatly enhance DynamoDB’s efficiency.

Understanding Write Capacity Units in Provisioned Mode for DynamoDB

In Amazon DynamoDB’s Provisioned Capacity mode, Write Capacity Units (WCUs) allow developers to tailor database performance to predictable workloads. This mode requires predefining the number of write operations your application will need, enabling you to anticipate and control the cost structure effectively.

Each WCU is designed to support one standard write per second for a data item that’s no larger than 1 KB. When transactional writes are required—operations involving more than one condition or check—two WCUs are consumed per second for a single 1 KB write.

If your data items exceed the 1 KB threshold, the required WCUs must be scaled accordingly. For instance, writing a 2.8 KB item would necessitate 3 WCUs (since 2.8 divided by 1 equals 2.8, which is then rounded up to 3). By accurately estimating your workload and allocating the proper number of WCUs, you create a resilient infrastructure that’s both efficient and cost-conscious.

How to Calculate DynamoDB Throughput with Practical Illustration

To demonstrate how throughput calculations translate to real-world applications, consider a scenario involving a high-read and write-intensive system. Suppose your application processes 50 read operations per second. Each item is approximately 6 KB in size and requires strong consistency. In On-Demand mode, one strongly consistent read of up to 4 KB consumes one Read Request Unit (RRU). Since each item in this case is 6 KB, it requires two RRUs (6 divided by 4 = 1.5, rounded up). Therefore, 50 reads per second will cost 100 RRUs per second.

Now, let’s address writes. Suppose you’re running in Provisioned mode and writing 80 items per second, with each item measuring 2.5 KB. Since every WCU supports 1 KB, each item would require 3 WCUs (2.5 divided by 1 = 2.5, rounded up). Therefore, 80 items multiplied by 3 equals 240 WCUs needed.

Such accurate computations empower developers to prevent under-provisioning or overspending and maintain optimal responsiveness.

Deciding Between On-Demand and Provisioned Modes

Selecting the appropriate DynamoDB capacity mode hinges on the nature of your application’s traffic. On-Demand mode is most suitable for applications with unpredictable usage patterns. This includes early-stage platforms, startup projects, or services that experience infrequent but intense bursts of traffic. With On-Demand, you don’t need to estimate usage in advance, which helps avoid paying for unused capacity. AWS automatically adjusts the capacity based on demand, ensuring your database can handle sudden traffic spikes gracefully.

Provisioned mode is better suited for mature applications with predictable and consistent access patterns. By specifying the number of read and write capacity units in advance, you retain control over performance and costs. If your usage remains stable or grows at a predictable rate, this mode can offer significant cost benefits. Additionally, you can integrate auto-scaling within the Provisioned mode, which dynamically adjusts capacity based on CloudWatch metrics, allowing a balance between control and flexibility.

Tools and Techniques for Monitoring DynamoDB Performance

Configuring WCUs and RCUs accurately is only part of the DynamoDB optimization process. Ongoing performance monitoring plays a critical role in ensuring cost-efficiency and application reliability. Amazon CloudWatch provides essential insights into consumption patterns and resource utilization. Key metrics include:

ConsumedReadCapacityUnits: Shows how much read capacity is being used.
ConsumedWriteCapacityUnits: Indicates write throughput usage.
ThrottledRequests: Reveals requests that were denied due to exceeding provisioned capacity.

By closely watching these metrics, developers can adjust configurations proactively before issues occur. For example, a sudden increase in throttled write operations might indicate that the current WCU allocation is insufficient and requires adjustment.

AWS also supports the integration of DynamoDB with Application Auto Scaling. This service adjusts provisioned throughput based on defined rules and observed load. If, for instance, read capacity consistently hits 80% of its limit, you can set a rule to automatically increase capacity. Conversely, during periods of low traffic, the system can scale down, avoiding unnecessary expenses.

Strategic Methods to Optimize AWS DynamoDB Expenses

Amazon DynamoDB is a powerful NoSQL database solution that offers near-infinite scalability and low-latency performance. However, its pay-per-use pricing model can lead to mounting costs if not managed with precision. To ensure optimal budget utilization without compromising efficiency, it’s imperative to adopt advanced cost-control practices. Below, we explore a series of refined strategies designed to optimize your DynamoDB operations, minimize unnecessary spending, and enhance overall resource efficiency.

Refine Data Payloads to Reduce Consumption

Minimizing the size of each record stored in DynamoDB has a direct correlation with cost reduction. Every attribute within a record contributes to the total size, which influences the number of read and write capacity units consumed. By eliminating redundant fields, unused metadata, or verbose string values, you can streamline data payloads. Opt for compact data structures and concise formatting standards. This not only conserves space but reduces the computational effort required for both read and write operations.

For example, consider storing dates as Unix timestamps rather than long string formats, and use abbreviated attribute names when possible without compromising clarity. Keeping records lean ensures each capacity unit is used to its fullest potential.

Leverage Eventual Consistency for Non-Critical Reads

In scenarios where immediate consistency is not a strict requirement, configuring your tables to utilize eventually consistent reads can significantly cut read costs. With this approach, DynamoDB returns data that might not reflect the most recent updates, but still provides high availability and performance. This read model is ideal for use cases such as analytics dashboards, background synchronization jobs, or read-heavy reporting tasks, where absolute accuracy in real time isn’t necessary.

By switching from strongly consistent reads to eventually consistent reads, you effectively reduce your Read Capacity Unit (RCU) consumption by half, which over time leads to substantial cost savings—particularly for applications with high read throughput.

Consolidate Transactions Using Batch APIs

DynamoDB offers BatchGetItem and BatchWriteItem operations to allow developers to execute multiple read or write actions in a single request. These batch methods are especially useful for reducing the per-operation overhead that accumulates when handling individual API calls. By bundling multiple operations together, not only do you reduce network round-trips, but you also optimize your usage of capacity units.

Batch operations are particularly advantageous during bulk data processing tasks, periodic data migrations, or importing/exporting datasets across tables. Efficient use of these APIs minimizes API throttling risks and ensures smoother performance under large data loads.

Automate Data Expiration with Time-To-Live

DynamoDB’s built-in Time-to-Live (TTL) mechanism enables the automatic removal of outdated or ephemeral data. With TTL, you designate a timestamp attribute for each item, after which the record becomes eligible for automatic deletion. This is highly beneficial for managing data that has a natural expiration cycle, such as session tokens, cache records, promotional content, or activity logs.

By purging obsolete items without human intervention, TTL helps prevent table bloat and reduces ongoing storage costs. In addition, removing unneeded data lessens the workload for scans, queries, and index maintenance, further optimizing performance and cost.

Audit and Refine Use of Secondary Indexes

While Global Secondary Indexes (GSIs) and Local Secondary Indexes (LSIs) enhance the flexibility and granularity of queries, they introduce additional cost layers. Each index consumes capacity units for writes and retains a portion of your data separately, thus increasing storage expenses.

To mitigate this, conduct regular audits to evaluate whether each index actively contributes to application functionality. Unused or infrequently accessed indexes should be deprecated. Moreover, avoid indexing overly broad attributes or ones with low cardinality, as this can result in inefficient query patterns and bloated storage utilization.

Consider designing your primary table schema to accommodate as many queries as possible before opting for secondary indexes. If indexes are essential, monitor their usage metrics through CloudWatch to ensure they remain valuable.

Implement Adaptive Capacity Management

Adaptive capacity is a native feature that helps DynamoDB automatically adjust throughput to accommodate uneven workloads without overprovisioning. While this feature is typically enabled by default, it’s vital to understand how partition keys affect throughput distribution.

To get the most from adaptive capacity, design partition keys that support an even distribution of requests. Hot partitions—where a single key receives disproportionate traffic—can lead to throttling and underutilized capacity elsewhere. A balanced key design enhances the system’s ability to reallocate throughput dynamically, thereby minimizing cost and boosting performance consistency.

Use On-Demand Mode Judiciously

DynamoDB offers both provisioned and on-demand capacity modes. While on-demand mode allows you to pay per request without pre-allocating throughput, it is most economical for applications with unpredictable or low-volume traffic patterns. For workloads with stable or predictable usage, switching to provisioned capacity with Auto Scaling enables better cost control.

Evaluate historical traffic patterns using CloudWatch metrics to determine the right capacity mode. Strategic switching based on usage trends can lead to better financial outcomes without degrading responsiveness.

Archive Infrequently Accessed Data

Not all data needs to be available in real time. For information that’s seldom queried—such as historical logs, past orders, or cold analytics—you can periodically archive these items into more cost-effective storage services like Amazon S3 or Glacier. Offloading seldom-used records reduces both storage and capacity unit consumption in DynamoDB while preserving long-term accessibility.

Implementing a data lifecycle management policy that automatically moves stale data can ensure your DynamoDB tables stay lean, responsive, and cost-efficient.

Monitor Usage with Granular Metrics

The most effective cost optimization strategy starts with observability. AWS CloudWatch offers detailed insight into table-level metrics such as throttled requests, consumed capacity, and read/write patterns. Use these metrics to pinpoint usage anomalies, underutilized resources, and sudden spikes that may warrant investigation.

Establish alarms and dashboards to track high-cost operations and ensure your capacity settings align with actual traffic. An informed view of performance trends enables proactive decision-making and prevents financial inefficiencies.

Embracing a Proactive Strategy for DynamoDB Scalability

Adopting a proactive capacity management strategy involves more than calculating the right number of RCUs and WCUs. It includes periodic reviews of table performance, refinement of access patterns, and architectural foresight. For instance, sharding your data effectively and distributing access evenly can help avoid hot partitions, which often lead to throttling.

Equally important is ensuring that DynamoDB remains tightly integrated with other AWS services such as Lambda, API Gateway, and Kinesis. These integrations can help form serverless architectures that are agile, scalable, and highly cost-effective. Lambda’s event-driven processing, for example, complements DynamoDB’s scalable storage perfectly in a modern application stack.

DynamoDB Best Practices for Modern Cloud Architects

Whether you’re architecting for high availability, responsiveness, or minimal cost, adhering to DynamoDB best practices can provide a significant advantage. Key among these are:

Normalize and denormalize data thoughtfully depending on your query patterns.
Use sparse indexes to limit unnecessary data ingestion.
Implement retries with exponential backoff for fault tolerance.
Monitor throughput and latency to detect anomalies quickly.

These tactics, while often overlooked, build a solid foundation for robust data handling and efficient resource usage.

Real-World Use Cases Demonstrating DynamoDB Flexibility

DynamoDB’s flexible architecture has made it a popular choice for industries ranging from gaming to finance. Game developers often use On-Demand mode during beta launches, where usage is erratic and spikes during promotional events. Financial platforms, on the other hand, typically choose Provisioned mode to maintain strict control over cost and performance due to high compliance standards.

A travel booking platform, for instance, may start with On-Demand mode during launch and transition to Provisioned mode once traffic patterns stabilize. With predictive scaling policies and thorough monitoring, the platform can maintain uptime during seasonal peaks while keeping costs within budget during slower periods.

Final Thoughts

Mastering how Read and Write Capacity Units work in both On-Demand and Provisioned Modes can make a significant difference in how effectively your applications utilize AWS DynamoDB. By understanding the trade-offs and calculations involved, organizations can architect data solutions that are both scalable and financially sustainable.

Whether you’re running a low-latency game backend, an IoT ingestion service, or an eCommerce storefront, aligning DynamoDB configurations with your real-world usage patterns is key. With precise throughput planning, automated scaling, and mindful cost strategies, DynamoDB can empower your workload with predictable performance and controlled cloud spend.

Amazon DynamoDB’s dual-mode capacity configuration grants developers and DevOps teams the flexibility to tailor database performance to precise workload demands. On-Demand capacity is ideally suited for applications requiring agile, real-time scalability with minimal upfront configuration. It removes the complexity of forecasting usage and ensures resilience against traffic volatility, making it a pragmatic choice during early development or during unpredictable user demand cycles.

Provisioned capacity, in contrast, introduces precision and control. When correctly configured, it can deliver significant cost savings for steady-state applications while offering a degree of predictability in budgeting. It supports fine-tuning at a granular level, particularly when used in conjunction with auto-scaling features and effective key design practices.

In Provisioned Mode, RCUs and WRUs empower developers with a fine-grained control mechanism for capacity management. When workloads are steady and predictable, this approach ensures optimal performance and cost-efficiency through strategic resource allocation. It suits enterprises that value deterministic scaling and have insight into usage patterns.

Conversely, On-Demand Mode removes the need for capacity estimation. Write and read operations scale automatically based on demand, offering a frictionless experience that suits dynamic, event-driven, or emerging workloads. This model reduces overhead and simplifies the development process by allowing teams to concentrate on innovation without the distraction of infrastructure tuning.
