Performance efficiency pillar in AWS - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of the Performance Efficiency pillar in cloud architecture?

To use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve.

beginner

Name one way to improve performance efficiency in AWS.

Use managed services like Amazon DynamoDB or Amazon Aurora that automatically scale and optimize performance.

intermediate

Why is monitoring important for performance efficiency?

Monitoring helps identify bottlenecks and resource usage patterns so you can adjust resources to keep performance optimal.

intermediate

What does 'right-sizing' mean in the context of performance efficiency?

Choosing the correct size and type of resources (like instances or storage) to match workload needs without over-provisioning.

beginner

How can caching improve performance efficiency?

Caching stores frequently accessed data closer to users or applications, reducing latency and load on backend systems.

Which AWS service helps automatically scale compute capacity to maintain performance?

A Amazon S3

B Amazon EC2 Auto Scaling

C AWS Lambda

D Amazon RDS

Amazon EC2 Auto Scaling adjusts the number of EC2 instances to meet demand and maintain performance.

What is a key benefit of using managed services for performance efficiency?

A They increase latency

B They require manual patching

C They handle scaling and maintenance automatically

D They limit resource usage

Managed services automatically handle scaling and maintenance, helping maintain efficient performance.

Which practice helps reduce latency by storing data closer to users?

A Caching

B Right-sizing

C Load balancing

D Encryption

Caching stores data closer to users, reducing the time it takes to access frequently used information.

What does 'right-sizing' help prevent?

A Data loss

B Network outages

C Security breaches

D Over-provisioning resources

Right-sizing ensures resources match workload needs, avoiding waste from over-provisioning.

Why should you monitor your cloud resources for performance?

A To identify bottlenecks and optimize resource use

B To increase costs

C To disable security features

D To reduce data backups

Monitoring helps find performance issues and adjust resources to keep systems efficient.

Explain the key strategies to achieve performance efficiency in AWS cloud environments.

Think about how AWS services and practices help maintain fast and efficient systems.

Describe how caching and auto scaling contribute to the performance efficiency pillar.

Consider how these techniques improve speed and resource use.
