Question

A company runs a highly available data collection application on Amazon EC2 in the eu-north-1 Region. The application collects data from end-user devices and writes records to an Amazon Kinesis data stream and a set of AWS Lambda functions that process the records .The company persists the output of the record processing to an Amazon S3 bucket in eu-north-1. The company uses the data in the S3 bucket as a data source for Amazon Athena.

Options

  • AIn each of the Iwo new Regions set up the Lambda functions to run in a VPC. Set up an S3
  • BTurn on S3 Transfer Acceleration on the S3 bucket in eu-north-1. Change the application to use
  • CCreate an S3 bucket in each of the two new Regions. Set the application in each new Region to
  • DIncrease the memory requirements of the Lambda functions to ensure that they have multiple

Why each option

The company needs to extend its highly available data collection application, currently in eu-north-1 using Kinesis, Lambda, and S3, to two new AWS Regions.

AIn each of the Iwo new Regions set up the Lambda functions to run in a VPC. Set up an S3Correct

Setting up the Lambda functions to run in a VPC in each of the two new regions allows for localized, secure processing of data, potentially connecting to regional Kinesis streams and S3 buckets, ensuring data collection efficiency and compliance by keeping processing near the data source.

BTurn on S3 Transfer Acceleration on the S3 bucket in eu-north-1. Change the application to use

S3 Transfer Acceleration speeds up uploads to a single S3 bucket, but it does not establish a multi-region data collection architecture or provide localized processing capabilities for Lambda functions.

CCreate an S3 bucket in each of the two new Regions. Set the application in each new Region to

While creating S3 buckets in new regions is part of a multi-region strategy, this option solely focuses on S3 and doesn't address the distributed processing of Kinesis or Lambda functions, which are critical components of the application.

DIncrease the memory requirements of the Lambda functions to ensure that they have multiple

Increasing the memory requirements of Lambda functions only improves performance for individual function invocations; it does not address the strategic architectural requirements for multi-region deployment or global data collection.

Concept tested: Multi-region data collection and processing architecture
