What is AWS DynamoDB | Amazon DynamoDB
Amazon DynamoDB is a completely managed NoSQL database service that provides quick and predictable performance with consistent adaptability. DynamoDB lets you offload the managerial weights of working and scaling a disseminated database with the goal that you don't need to stress over hardware provisioning, setup, and configuration, replication, software patching, or cluster scaling. DynamoDB additionally offers encryption at rest, which kills the operational burden and complexity involved with ensuring delicate data.
With DynamoDB, you can make database tables that can store and recover any measure of data and serve any degree of request traffic. You can scale up or scale down your tables' throughput limit without downtime or performance degradation. You can utilize the AWS Management Console to monitor resource usage and performance matrices.
DynamoDB gives on-demand backup capability. It permits you to make full backups for your tables for long-term retention and archival for regulatory compliance needs.
You can make on-demand backups and empower point-in-time recovery for your Amazon DynamoDB tables. Point-in-time recovery shields your tables from accidental write or deletes operations. With point-in-time recovery, you can reestablish that table to any point in time during the most recent 35 days.
DynamoDB allows you to delete expired items from tables automatically to help you reduce storage usage and the cost of storing data that is no longer relevant.
Performance at scale
DynamoDB supports a portion of the world's largest scale applications by giving consistent, single-digit millisecond response times at any scale. You can build applications with virtually unlimited throughput and storage. DynamoDB global tables imitate your data over different AWS Regions to give you quick, nearby access to data for your internationally disseminated applications. For use cases that require much quicker access with microsecond dormancy, DynamoDB Accelerator (DAX) gives a completely oversaw in-memory store.
No servers to manage
DynamoDB is serverless without any servers to provision, patch, or manage and no software to install, maintain, or operate. DynamoDB naturally scales tables here and there to modify for limit and look after execution. Accessibility and adaptation to non-critical failure are inherent, eliminating the need to architect your applications for these capabilities. DynamoDB gives both provisioned and on-demand capacity modes with the goal that you can advance expenses by determining limit per outstanding task at hand or paying for just the resources you consume.
DynamoDB supports ACID transactions to empower you to construct business-critical applications at scale. DynamoDB encrypts all data by default and gives fine-grained identity and access control on the entirety of your tables. You can make full backups of hundreds of terabytes of data in a flash with no performance effect on your tables, and recover to any point in time in the first 35 days with no downtime. DynamoDB is likewise supported by a service level agreement for ensured accessibility.
Serverless Web Apps
Build powerful web applications that automatically scale up and down. You don't need to maintain servers, and your applications have automated high availability.
Use DynamoDB and AWS AppSync to build interactive mobile and web apps with real-time updates, offline data access, and data sync with built-in conflict resolution.
Build flexible and reusable microservices using DynamoDB as a serverless data store for consistent and fast performance.
Organizations in the advertising technology (ad tech) vertical use DynamoDB as a key-value store for putting away different sorts of advertising data, for example, user profiles, client events, clicks, and visited links. Relevant use cases incorporate real-time bidding (RTB), ad targeting, and attribution. These utilization cases require a high request rate (a great many solicitations for every second), low predictable latency, and reliability. Organizations use caching through DynamoDB Accelerator (DAX) when they have high read volumes or need submillisecond read latency. Progressively, advertisement tech organizations need to convey their RTB and promotion focusing on stages in more than one geographical AWS Region, which requires data replication between Regions.
Organizations in the gaming vertical use DynamoDB in all capabilities of gaming platforms, including game state, player data, session history, and leaderboards. The primary advantages that these organizations get from DynamoDB are its capacity to scale dependably to millions of concurrent users and requests while guaranteeing reliably low latency estimated in single-digit milliseconds. Furthermore, as a completely overseen administration, DynamoDB has no operational overhead, so game designers can concentrate on building up their games as opposed to overseeing databases. Also, as game designers are progressively hoping to grow from a solitary AWS Region to various AWS Regions, they can depend on DynamoDB global tables for different Region, dynamic replication of data.
Numerous organizations in the retail space use commonDynamoDB configuration examples to convey reliably low latency for strategic use cases. Being liberated from scaling concerns and operational weight is a key upper hand and an enabler for high velocity, extreme-scaled events like Amazon Prime Day, whose sizes are hard to estimate. Scaling all over permits these clients to pay just for the limit they need and keeps valuable specialized resources concentrated on advancements instead of activities.
Banking and finance
As organizations in banking and money construct more cloud-native applications, they try to utilize fully managed services to increase agility, reduce time to market, and minimize operational overhead. Simultaneously, they need to guarantee the security, reliability, and high accessibility of their applications. As these organizations extend their current administrations that are backed by legacy mainframe systems, they find that legacy systems can't fulfill the versatility needs of their growing user base, new platforms like mobile applications, and the resulting increases in traffic. To take care of this issue, they imitate data from their centralized servers to the cloud to offload the traffic.
Media and entertainment
Media and entertainment organizations use DynamoDB when they require an outrageous size of throughput and concurrency, low latency, and reliability. DynamoDB scales flexibly to deal with the load and keeps up low latency that is critical for real-time scenarios, like video streaming and interactive content. In such situations, the number of simultaneous clients can arrive at millions, and no database handles that sort of concurrency just as DynamoDB. Despite such high simultaneousness, the latency stays low, bearing individual user's optimal user experience, regardless of whether it includes recovering their media, or partaking in an intuitive, constant occasion. These organizations use DynamoDB to address their adaptability challenges and to maintain their attention on feature development and not on database management.
