DynamoDB, a managed NoSQL service provided by Amazon Web Services, is a NoSQL database. It's designed to deliver high scalability and low latency for applications requiring fast, predictable performance. DynamoDB can handle both structured and semistructured data. AWS Training in Pune
DynamoDB, at its core, is a NoSQL fully-managed database. It allows developers to create applications that can handle traffic of any size, from just a few requests a month to millions per second. It's highly durable and reliable, with automatic multi-region replicating and continuous backups. DynamoDB is well-suited to use cases that demand real-time processing of large amounts data and low latency access.
DynamoDB has many features and concepts.
Data model: DynamoDB is based on a key-value database, in which each item can be uniquely identified using a primary keys. The primary key may be a simple key (partition) or composite key (partition and sort key). This model allows fast and efficient retrieval of data.
Scalability DynamoDB has been designed to scale horizontally. This allows you to manage increased traffic and data volume seamlessly. It automatically distributes the data across multiple servers to ensure that performance is consistent even as your application grows.
Performance DynamoDB offers a latency of milliseconds for both read and write operations regardless of data size. This is achieved by replicating the data across multiple availability zone within a given region, and using SSD storage for fast access.
Automatic replication: DynamoDB has built-in multiregion replication that allows you to replicate data across multiple AWS Regions for improved availability and disaster recover. This will ensure that your application is still operational in the event of regional outages.
Flexibility : DynamoDB allows you to scale read and write capacities independently, according to the needs of your application. DynamoDB automatically handles the infrastructure changes to increase or decrease capacity.
Global Tables DynamoDB Global Tables allows you to replicate data in multiple regions and automatically resolve conflict. This feature allows users to access data in different locations with low latency and increases the availability of an application. AWS Classes in Pune
DynamoDB streams: DynamoDB streams is a feature which captures an ordered sequence of item level modifications in a DynamoDB Table. You can capture data changes and trigger events, or replicate the data to another service for further processing.
Integration With AWS Services DynamoDB seamlessly integrates with other AWS Services, such as AWS CloudTrail and Amazon Kinesis. This allows you build serverless architectures that leverage the power of AWS.
Security and Administration : DynamoDB offers a variety of security features including encryption in transit and at rest, access control with AWS Identity and Access Management, and integration with AWS CloudTrail to audit and comply. AWS CloudWatch provides monitoring and management features.
Pricing DynamoDB's pricing is determined by the storage capacity used, provisioned throughput, and other features such as Global Tables or DynamoDB streams. It offers different pricing options to optimize costs depending on the application requirements. AWS Course in Pune
DynamoDB, a NoSQL database managed by AWS, is highly scalable. The ability of DynamoDB to handle high-volume, low-latency workloads along with its flexibility, automatic replication and seamless integration with AWS makes it a popular option for building high performance applications in the cloud.
