Amazon DynamoDB: Everything you need to know + What’s the Latest

Amazon DynamoDB: Everything you need to know + What’s the LatestAmazon DynamoDB is a fully-managed (“serverless”) and NoSQL (nonrelational) database service, available on Amazon Web Services. DynamoDB is highly scalable, meaning you can start really small and grow very big without needing to re-deploy or re-architect. It also offers a flexible model which uses automatic scaling of throughput capacity, this means that it scales compute capacity based on demand, saving money and lowering entry costs. This makes it a great fit for mobile, gaming, IoT, and other high-growth and high-volume applications.

The Amazon DynamoDB Advantage

Amazon DynamoDB offers multiple advantages over other NoSQL database management systems such as Apache Cassandra and MongoDB. The integration between DynamoDB and other AWS services is especially beneficial. If you are already an AWS user, it’s a great choice.

Simple Set-up

As a serverless database service, setting up is easy. Simply open the AWS Management Console and utilize the wizard. Conversely, in order to set up an on-premises MongoDB instance, you need to follow a long list of instructions and may have to resolve authentication errors.

AWS Security

Security for DynamoDB is governed by AWS Identity and Access Management (IAM). You can also use other AWS security features to enhance the controls. Although MongoDB is secure, there have been security breaches in the past due to improper configuration and management.

What are the costs?

Both DynamoDB and MongoDB are free for a pre-defined period of time. After free usage expires, DynamoDB calculates cost on the basis of reads and writes, while MongoDB calculates cost according to consumed storage.

What’s the latest?

There are many new features ensure that help this service stand out from the competition. These include:

Amazon DynamoDB Accelerator (DAX)

DAX is a fully managed, secure, and scalable DynamoDB cache service. It is suitable for read-intensive workloads and provides major improvements in DynamoDB’s response time. DAX clusters are hosted by and run in Amazon Virtual Private Cloud (Amazon VPC).

A DAX client should be installed on the Amazon EC2 instance hosting your application in VPC. All requests are routed via the DAX client, which fetches data, if available, from the DAX cluster (a cache hit). If data is not available in the cluster, it will be extracted from DynamoDB (a cache miss). Results will be provided to your application via the DAX cluster.

Caching data in DAX clusters reduces overall read requests on DynamoDB tables, which can save you money. Companies such as Tinder, Expedia, and Genesys all use DAX to enhance the customer experience by providing sub-millisecond response times to customer queries.

Encryption at Rest

Encryption at rest is the newest addition to DynamoDB. To enable it, simply create a new DynamoDB table and uncheck “Use default settings”. Then go to the “Encryption at Rest” section and select “Enable encryption”. AES-256 and AWS Key Management Service (KMS) keys will be used to encrypt the tables and indexes. It is important to note that encryption will not cause latency or performance issues while executing DML and DDL operations.

Scheduled Auto-Scaling

Scheduled auto-scaling leads to a highly available, fault-tolerant, and cost-effective setup. Defining your scaling policy and auto-scaling in DynamoDB is simple once you understand the steps involved.

Global Tables

Global Tables helps developers build highly resilient, multi-region applications. It ensures that data is close to users located in various locations, leading to a reduction in latency. From a developer’s point of view, data updated in a specific region will automatically synchronize with tables located in other regions. However, prices vary for different regions and customers are charged for replicated writes, reads, and storage.


The Low-Down

Amazon DynamoDB has an advantage over other NoSQL databases due to its constant stream of new features and the support from the AWS ecosystem. Being a serverless solution eases a tremendous burden for database administrators. DBAs long had to deal with managing servers and server infrastructure, with serverless computing options they can focus on the database and not the supporting architecture. If you are looking for a NoSQL database service that can deploy quickly, scale easily and deliver on performance, you can be sure it’s a great option.

Cloud Protection Manager (CPM)  supports automated backup and recovery for DynamoDB

Recently N2W Software, a Veeam company, leading provider of backup and recovery solutions for Amazon Web Services (AWS), announced availability of Cloud Protection Manager v2.3. Among other new features, this new version includes automated backup and recovery operations for Amazon DynamoDB. Other new features in this release include cross-region and cross-account disaster recovery for Amazon Aurora databases, RESTful API, AWS CloudFormation template, a newly re-designed reporting tab and enhanced permissions for independent users.
