Questions and Answers

What is the primary benefit of using an Amazon SQS queue as a destination for jobs?

It allows for automatic scaling based on the load on the primary server.

It minimizes costs by automatically scaling up the compute nodes.

It enables faster query and retrieval of files.

It decouples the primary server from the compute nodes, preventing job loss in the event of a failure. (correct)

What is the recommended indicator to configure the Auto Scaling group based on?

The number of EC2 instances.

The load on the compute nodes.

The size of the Amazon SQS queue. (correct)

The load on the primary server.

What is the purpose of using an Auto Scaling group of Amazon EC2 instances for the compute nodes?

To minimize costs by automatically scaling down the compute nodes.

To allow for automatic scaling based on the workload. (correct)

To enable faster query and retrieval of files.

To decouple the primary server from the compute nodes.

Study Notes

Improving Performance and Availability with CloudFront and Global Accelerator

Point one domain name to the CloudFront DNS name for dynamic content and the other to the accelerator DNS name for static content.
Use the domain names as endpoints for the web application.

Migrating a Distributed Application to AWS

To modernize an application with a solution that maximizes resiliency and scalability, implement the primary server and compute nodes with Amazon EC2 instances that are managed in an Auto Scaling group.
This design allows for automatic scaling based on the workload, ensuring the application can handle variable workloads while minimizing costs.

Cloning Production Data into a Test Environment

To clone production data with high I/O performance and without affecting the production environment, take EBS snapshots of the production EBS volumes and restore them onto new EBS volumes in the test environment.
Attach the new EBS volumes to EC2 instances in the test environment.

Designing an API Gateway URL with a Custom Domain Name

To design an API Gateway URL with a custom domain name, use Amazon Route 53, Amazon API Gateway, and a corresponding certificate.
This allows third-party services to use HTTPS and provides a secure interface for backend microservice APIs.

Storing and Retrieving Call Transcript Files

To optimize the storage and retrieval of call transcript files, store individual files with tags in Amazon S3 Glacier Instant Retrieval.
Query the tags to retrieve the files from S3 Glacier Instant Retrieval, allowing for quick access to files less than 1-year-old and cost-effective storage of older files.
