Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multiregion, multimaster, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications. DynamoDB can handle more than 10 trillion requests per day and can support peaks of more than 20 million requests per second.

Many of the world's fastest growing businesses such as Lyft, Airbnb, and Redfin as well as enterprises such as Samsung, Toyota, and Capital One depend on the scale and performance of DynamoDB to support their mission-critical workloads.

Hundreds of thousands of Amazon Web Services customers have chosen DynamoDB as their key-value and document database for mobile, web, gaming, ad tech, IoT, and other applications that need low-latency data access at any scale. Create a new table for your application and let DynamoDB handle the rest.

This product is available in Amazon Web Services China (Beijing) region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD.

Benefits

Performance at Scale
DynamoDB supports some of the world’s largest scale applications by providing consistent, single-digit millisecond response times at any scale. You can build applications with virtually unlimited throughput and storage. DynamoDB global tables replicate your data across multiple Amazon Web Services Regions (outside of mainland China) to give you fast, local access to data for your globally distributed applications. For use cases that require even faster access with microsecond latency, DynamoDB Accelerator (DAX) provides a fully managed in-memory cache.
Serverless
With DynamoDB, there are no servers to provision, patch, or manage and no software to install, maintain, or operate. DynamoDB automatically scales tables up and down to adjust for capacity and maintain performance. Availability and fault tolerance are built in, eliminating the need to architect your applications for these capabilities. DynamoDB provides both provisioned and on-demand capacity modes so that you can optimize costs by specifying capacity per workload, or paying for only the resources you consume.
Enterprise Ready
DynamoDB supports ACID transactions to enable you to build business-critical applications at scale. DynamoDB encrypts all data by default and provides fine-grained identity and access control on all your tables. You can create full backups of hundreds of terabytes of data instantly with no performance impact to your tables, and recover to any point in time in the preceding 35 days with no downtime. DynamoDB is also backed by a service level agreement for guaranteed availability.

Use Cases

Ad Tech

Companies in the advertising technology (ad tech) vertical use DynamoDB as a key-value store for storing various kinds of marketing data, such as user profiles, user events, clicks, and visited links. Applicable use cases include real-time bidding (RTB), ad targeting, and attribution. These use cases require a high request rate (millions of requests per second), low predictable latency, and reliability. Companies use caching through DynamoDB Accelerator (DAX) when they have high read volumes or need submillisecond read latency. Increasingly, ad tech companies need to deploy their RTB and ad targeting platforms in more than one geographical Amazon Web Services Region, which requires data replication between Regions.

#User events, click streams, and impressions data store
#Metadata stores for assets
#Popular-item caches

Gaming

Companies in the gaming vertical use DynamoDB in all capabilities of game platforms, including game state, player data, session history, and leaderboards. The main benefits that these companies get from DynamoDB are its ability to scale reliably to millions of concurrent users and requests while ensuring consistently low latency measured in single-digit milliseconds. In addition, as a fully managed service, DynamoDB has no operational overhead, so game developers can focus on developing their games instead of managing databases. Also, as game developers are increasingly looking to expand from a single Amazon Web Services Region to multiple Amazon Web Services Regions, they can rely on DynamoDB global tables for multiple-Region, active-active replication of data.

#Player data stores
#Player session history data stores
#Leaderboards

Retail

Many companies in the retail space use common DynamoDB design patterns to deliver consistently low latency for mission-critical use cases. Being free from scaling concerns and operational burden is a key competitive advantage and an enabler for high-velocity, extreme-scaled events such as Amazon Prime Day, whose magnitudes are difficult to forecast. Scaling up and down allows these customers to pay only for the capacity they need and keeps precious technical resources focused on innovations rather than operations.

Banking & Finance

As companies in banking and finance build more cloud-native applications, they seek to use fully managed services to increase agility, reduce time to market, and minimize operational overhead. At the same time, they have to ensure the security, reliability, and high availability of their applications. As these companies expand their existing services that are backed by legacy mainframe systems, they find that legacy systems are unable to meet the scalability demands of their growing user base, new platforms such as mobile applications, and the resulting increases in traffic. To solve this problem, they replicate data from their mainframes to the cloud to offload the traffic.

#Event-driven transaction processing
#Fraud detection
#Mainframe offloading and change data capture

Media & Entertainment

Media and entertainment companies use DynamoDB when they require an extreme scale of throughput and concurrency, low latency, and reliability. DynamoDB scales elastically to handle the load and maintains low latency that is critical for real-time scenarios, such as video streaming and interactive content. In such scenarios, the number of concurrent users can reach millions, and no database handles that kind of concurrency as well as DynamoDB. Despite such high concurrency, the latency remains low, affording individual users optimal user experience, whether it involves retrieving their media, or participating in an interactive, real-time event. These companies use DynamoDB to address their scalability challenges and to keep their focus on feature development and not on database management.

#Digital rights management data stores

Software & Internet

One key commonality among software companies and many other DynamoDB customers is internet scale. These companies’ use cases require the ability to accommodate extreme concurrency, request rates, and spikes in traffic. This concurrency is measured in millions of users and connections, and request rates can easily reach millions per second. DynamoDB has a proven record of being able to handle internet-scale use cases and their requirements while maintaining consistent, single-digit millisecond latency. With global tables, DynamoDB customers can easily expand their applications to multiple Amazon Web Services Regions for global reach and business continuity.
