AWS Certified Solutions Architect Associate (SAA-C03) - Resilient Design Scenario

The video tutorial discusses implementing resilient design for a widget maker's cloud migration. It covers using RDS for SQL Server and MySQL databases with multi-AZ deployments, enhancing payroll processing with read replicas, migrating user data to S3, and hosting a WordPress website using Elastic Load Balancer. The focus is on achieving resiliency and reliability in AWS cloud solutions.

What is the recommended database solution for the order processing system in the cloud?

• EC2 instance with MySQL

• EC2 instance with SQL Server

• RDS instance with MySQL

• RDS instance with Microsoft SQL Server

Why is a multi-AZ database important for the order processing system?

• To increase speed

• To ensure resiliency

• To improve security

• To reduce costs

What additional feature is implemented for the payroll system to handle intensive read operations?

• Clustering

• Multi-AZ deployment

• Read replica

• In-memory caching

How is user data managed in the cloud for resiliency?

• Stored in EC2 instances

• Stored in S3 buckets

• Stored in local servers

• Stored in RDS instances

What is a challenge when using S3 buckets for user data?
