Study Notes

Amazon Kinesis and Message Processing

Amazon Kinesis Data Analytics can enhance message processing capabilities in consumer applications.
Implementing Kinesis may necessitate architectural changes to the application.
FIFO queues are ideal for ordered message processing, while standard queues allow virtually limitless message volume.

Migrating Distributed Applications to AWS

A company aims to modernize a distributed application by migrating it to AWS.
The legacy architecture involved a primary server coordinating multiple compute nodes.
For resilient and scalable design:
- Option A: Use Amazon SQS with EC2 instances in an Auto Scaling group, leveraging scheduled scaling.
- Option B: Implement SQS with EC2 instances in Auto Scaling, triggered by queue size.
- Option C: Maintain the primary server and nodes with EC2 in Auto Scaling, reliant on server load.
- Option D: Use EC2 instances with EventBridge for job destination handling.

E-commerce Application Order Processing

An e-commerce application sends new order information to an Amazon API Gateway for processing.
Ensuring that order processing follows the exact order of receipt is essential.
Suggested solutions:
- Option A: Utilize API Gateway to publish messages to an SNS topic and subscribe a Lambda function for processing.
- Option B: Implement API Gateway to send messages to an SQS FIFO queue, invoking a Lambda function for order processing.
- Option C: Apply an API Gateway authorizer to manage request blocking during order processing.
- Option D: Send messages to an SQS standard queue via API Gateway, triggering a Lambda function for processing.

Data Analysis with Amazon Athena

Amazon Athena enables querying JSON logs stored in S3 without the need for transformation or additional infrastructure.
This serverless interactive query service uses standard SQL queries directly against S3 data.
Athena provides a low-overhead solution, supporting efficient and uncomplicated data analysis from existing log files.
