##Serverless IoT##

Out of the box, the AWS IoT console gives you your own searchable device registry with access to the device state and information about device shadows. You can enhance and customize the service using [Lambda](https://aws.amazon.com/lambda/) and [DynamoDB](https://aws.amazon.com/dynamodb/) to build a serverless backend with a customizable device database that can be used to store useful information about the devices as well as helping to track what devices are activated with an activation code if required. For queries related to how you can leverage DynamoDB for your organization, contact [SNDK Corp](https://www.sndkcorp.com/).

##Case study: Unlocking opportunities with AWS DynamoDB##

As companies in banking and finance build more cloud-native applications, they usefully managed services to increase agility, reduce time to market, and minimize operational overhead. **Vanguard** is a financial services company that started a cloud construction team to set up a lab architecture, allowing the team to experiment and innovate with any kind of open-source software within an enterprise-grade security architecture setup. By having a multitude of servers and applications, users can access any open-source application and marketplace and work on managing and automating user transactions, event-driven transaction processing, fraud detection, using a sandbox or live environment.

Many companies in the retail space use common DynamoDB design patterns. Being free from scaling concerns and the operational burden is a key competitive advantage and an enabler for high-velocity, extreme-scaled events such as **Amazon Prime Day**, whose magnitudes are difficult to forecast. Scaling up and down allows these customers to pay only for the capacity they need and keeps precious technical resources focused on innovation rather than operations.

One key commonality among software companies and many other DynamoDB customers is the ability to accommodate extreme concurrency, request rates, and spikes in traffic.

**Netflix** uses DynamoDB to run A/B testing that builds personalized streaming experiences for its 125+ million customers. To make your enterprise cloud journey a success, contact [SNDK Corp](https://www.sndkcorp.com/), your most trusted AWS consulting partner.

**Duolingo**, an online language learning site, uses DynamoDB to store 31 billion items on their online learning site. With courses provided in 80 languages, 24000 read units/second and 3300 write units/second. This is a read-heavy application, and DynamoDB is the perfect choice for a storage database.
