What is Amazon DynamoDB? Table of Contents Amazon DynamoDB, a fully managed NoSQL databank service, offers seamless scaling and predictable performance. DynamoDB takes care of all the administrative tasks associated with managing and configuring a distributed database. Because there is no need to store data or set up infrastructure, companies can save money. Businesses are also freed from the responsibility of managing and protecting their data. Most companies store their data in cloud storage. The AWS Cloud Practitioner Essentials certification course provides a basic understanding of data storage services in AWS. DynamoDB-suited use-cases Programs with high data volumes and tight latency constraints. As your data volume increases, JSON and complex SQL procedures may slow down your searches. DynamoDB will ensure that your queries have consistent latency, even if they’re large (up to 100 TBs). AWS Lambda can be used to create serverless apps. AWS Lambda provides auto-scaling, adaptive, and ephemeral computing as a response to event triggers. DynamoDB is an excellent choice for building Serverless apps because it has an HTTP API. It also uses IAM roles to authenticate and grant permission. Data sets are easy to access and have well-known access patterns. DynamoDB’s straight key/value access patterns make it an easy and reliable way to create and provide recommendations to users. How does Amazon DynamoDB function? DynamoDB uses B-trees and hashing to organize data. By hashing the partition key, data is first divided into different partitions. DynamoDB uses a two-tier backup strategy that includes duplication and long-term storage to protect data security. Amazon developers initially avoided Dynamo due to overheads like provisioning and managing partitions, nodes and other administrative tasks. The DynamoDB team developed AutoAdmin, a database management tool. AutoAdmin replaces a node if it fails to respond by transferring data from another. Advantages of Amazon DynamoDB Controlled Ecosystem: DynamoDB procures hardware, software, and sets up and manages a distributed cluster. It also drives continuous cluster operations for developers. It handles all the complex tasks of scaling, partitioning, and repartitioning your data to meet your I/O performance requirements. Amazon DynamoDB can scale: This allows you to meet your storage and bandwidth needs by extending the resources allocated to a table to hundreds, or even thousands of machines spread across multiple Availability Zones. Amazon DynamoDB delivers optimally fast performance and high throughput. It is also built on solid state drives that maximize efficiency even at high volumes. Additionally, because not all attributes are indexed, read and write operations are less expensive. Write activities only update the main index, which reduces read and write latency. Flexible: Amazon DynamoDB can be used by any customer. It does not require that they use a particular data type or integrity model. DynamoDB tables allow each data item to have multiple attributes and multi-valued characteristics, rather than a defined schema. Amazon S3 vs. DynamoDB Data objects are stored on solid state drives (SSDs) which are mirrored across three availability zones for high availability and long-term reliability. DynamoDB allows you to offload the administrative burden associated with scaling and maintaining a highly available distributed database cluster. You only pay for what is used. Amazon S3 is a redundant storage infrastructure that allows you store and retrieve any amount of data from any location on the internet. Architecture:

Amazon S3 is an object store that can store large amounts of unstructured binary information. It can store up to […]
