Recall & Review

What is a multi-tier architecture pattern?

A multi-tier architecture pattern divides an application into layers or tiers, such as presentation, logic, and data. Each tier handles a specific role, making the system easier to manage and scale.

Name the common tiers in a three-tier architecture.

The common tiers are: 1) Presentation tier (user interface), 2) Application tier (business logic), 3) Data tier (database and storage).

Why use multi-tier architecture in cloud applications?

It improves scalability, security, and maintenance by separating concerns. Each tier can be updated or scaled independently without affecting others.

In AWS, which services can be used for the data tier in a multi-tier architecture?

AWS services like Amazon RDS, Amazon DynamoDB, and Amazon S3 are commonly used for the data tier to store structured and unstructured data.

How does the application tier in AWS typically handle business logic?

The application tier can use AWS Elastic Beanstalk, AWS Lambda, or Amazon EC2 instances to run the business logic and process requests from the presentation tier.

Which tier in a multi-tier architecture handles user interaction?

A Application tier

B Network tier

C Data tier

D Presentation tier

The presentation tier is responsible for the user interface and interaction.

Which AWS service is best suited for storing relational data in the data tier?

A Amazon RDS

B Amazon S3

C AWS Lambda

D Amazon EC2

Amazon RDS is a managed relational database service ideal for structured data.

What is a key benefit of separating an application into multiple tiers?

A Easier maintenance and scalability

B Faster internet speed

C Lower electricity usage

D More complex code

Separating tiers allows independent updates and scaling, improving maintenance and scalability.

Which tier typically contains the business logic in a multi-tier architecture?

A Presentation tier

B Application tier

C Security tier

D Data tier

The application tier processes business rules and logic.

Which AWS service can be used to run code without managing servers in the application tier?

A Amazon EC2

B Amazon S3

C AWS Lambda

D Amazon RDS

AWS Lambda runs code in response to events without server management.

Explain the roles of each tier in a three-tier architecture pattern.

Think about how a website shows pages, processes actions, and stores information.

Describe how AWS services can be used to build each tier in a multi-tier architecture.

Consider which AWS services handle user access, code execution, and data storage.
