Your company is in the process of developing a next generation pet collar that collects biometric
information to assist families with promoting healthy lifestyles for their pets. Each collar will push
30kb of biometric data in JSON format every 2 seconds to a collection platform that will process
and analyze the data providing health trending information back to the pet owners and
veterinarians via a web portal. Management has tasked you to architect the collection platform
ensuring the following requirements are met:
– Provide the ability for real-time analytics of the inbound biometric
data
– Ensure processing of the biometric data is highly durable, elastic
and parallel
– The results of the analytic processing should be persisted for data
mining
Which architecture outlined below will meet the initial requirements for the collection platform?

A web design company currently runs several FTP servers that their 250 customers use to upload
and download large graphic files. They wish to move this system to AWS to make it more
scalable, but they wish to maintain customer privacy and keep costs to a minimum.
What AWS architecture would you recommend?

You have recently joined a startup company building sensors to measure street noise and air
quality in urban areas.
The company has been running a pilot deployment of around 100 sensors for 3 months. Each
sensor uploads 1KB of sensor data every minute to a backend hosted on AWS. During the pilot,
you measured a peak of 10 IOPS on the database, and you stored an average of 3GB of sensor
data per month in the database.
The current deployment consists of a load-balanced, auto scaled Ingestion layer using EC2
instances, and a PostgreSQL RDS database with 500GB standard storage
The pilot is considered a success and your CEO has managed to get the attention of some
potential Investors. The business plan requires a deployment of at least 100k sensors which
needs to be supported by the backend.
You also need to store sensor data for at least two years to be able to compare year over year
improvements.
To secure funding, you have to make sure that the platform meets these requirements and leaves
room for further scaling.
Which setup will meet the requirements?

Company B is launching a new game app for mobile devices. Users will log into the game using
their existing social media account. To streamline data capture, Company B would like to directly
save player data and scoring information from the mobile app to a DynamoDB table named
ScoreData. When a user saves their game, the progress data will be stored to the GameState S3
bucket. What is the best approach for storing data to DynamoDB and S3?
