At any size, the fully managed, serverless, NoSQL Amazon DynamoDB database operates at single-digit millisecond speeds.
Amazon DynamoDB: What is it?
DynamoDB is a serverless NoSQL database service that lets you build modern apps of any size. The serverless database Amazon DynamoDB offers zero scalability, no cold starts, no version upgrades, no maintenance windows, no patching, and no downtime. You just pay for the services you utilize. DynamoDB offers a broad range of security controls and compliance requirements. With improved resilience for internationally distributed applications and a 99.999% availability SLA, DynamoDB Global Tables is a multi-region, multi-active database. DynamoDB reliability is supported by automated backups, point-in-time recovery, and other capabilities. Amazon DynamoDB streams can be used to build serverless event-driven applications.Use cases
Make software applications
Develop internet-scale applications that support user-content metadata and caches, which require a lot of connections and parallelism to manage millions of users and millions of queries per second.
Create repositories for media metadata.
Scale throughput and concurrency for media and entertainment operations, such as interactive content and real-time video streaming, and lower latency with multi-Region replication between AWS Regions.
Ensure that the purchasing experiences are faultless.
Use design patterns when implementing shopping carts, inventory tracking, workflow engines, and customer profiles. Amazon DynamoDB is capable of handling millions of queries per second and facilitating large-scale, high-traffic events.
Massive gaming systems
Focus on fostering innovation when there are no operational costs. When creating your game platform, make sure to include player data, session history, and leaderboards for millions of users simultaneously.
Features of Amazon DynamoDB
Without a server
Using Amazon DynamoDB eliminates the need to setup servers, patch, administrate, install, maintain, and execute any software. DynamoDB provides uptime-free maintenance. There are no major, minor, or patch versions, nor are there any maintenance windows.
With DynamoDB's on-demand capacity mode, which provides pay-as-you-go pricing for read and write requests, you only pay for what you need. With on-demand, DynamoDB swiftly scales up or down your tables to meet capacity while maintaining performance without the need for management. Additionally, it scales down to zero when your table has no traffic or cold starts, saving you money on throughput.
NoSQL Amazon DynamoDB
NoSQL
DynamoDB is a NoSQL database that performs better than relational databases in terms of flexibility, management, scalability, and performance. Numerous use cases involving document and key-value data formats are supported by DynamoDB.
In contrast to relational databases, DynamoDB does not have a JOIN operator. We suggest denormalizing your data model to reduce database round trips and the computing resources needed to answer queries. DynamoDB is a NoSQL database that provides ACID transactions and outstanding read consistency for enterprise-grade applications.
Completely controlled
With DynamoDB's fully managed database service, you can concentrate on adding value for your customers. It manages a variety of tasks, including high availability, setup, configurations, security, backups, and hardware supply. This ensures that when a DynamoDB table is created, it is ready for production workloads right away. Amazon DynamoDB consistently improves its functionality, security, speed, availability, and dependability without requiring upgrades or downtime.
Performance in single-digit milliseconds at any scale
DynamoDB was created expressly to improve the speed and scalability of relational databases, attaining single-digit millisecond performance at any scale. To attain this size and performance, DynamoDB provides APIs that encourage efficient database use. DynamoDB is built for high-performance applications. It omits things like JOIN operations, which are inefficient and perform poorly at scale. DynamoDB continuously delivers single-digit millisecond performance for your application, regardless of the number of users—100 or 100 million.
A DynamoDB database: what is it?
The exact nature of this database is not widely known outside of Amazon. Despite being closed-source and private, the cloud-native database architecture has a development version called DynamoDB Local that is used on developer laptops and is built in Java.
When you set up DynamoDB on Amazon Web Services, you don't allocate preset disk sizes or specific machines. The capacity that has been provided, which comprises the quantity of transactions and kilobytes of traffic that you wish to support per second, is what you construct the database based on instead. Users specify a service level of read capacity units (RCUs) and write capacity units (WCUs).
As was already indicated, users frequently avoid making direct calls to the Amazon DynamoDB API. Instead, Amazon Web Services will be incorporated into their application to handle the back-end communication with the server.
DynamoDB data modeling has to be denormalized. For engineers used to dealing with both SQL and NoSQL databases, rethinking their data model is a challenging but doable step.
