3.1 Cloud Infrastructure

Question 1

What is the primary purpose of a responsibility matrix provided by a public cloud provider?

Answer 1

To clearly delineate who is responsible for different aspects of technology running in the cloud.

Question 2

How might a contract between an organization and a cloud provider affect the default responsibility matrix?

Answer 2

It can modify the default responsibility matrix to better fit specific needs and agreements, altering responsibility allocation.

Question 3

What is one main challenge associated with managing a hybrid cloud environment?

Answer 3

The complexity of configuring settings across different cloud providers, which often do not communicate directly.

Question 4

Why is it important for an organization to have a vendor risk management policy when working with third-party applications or devices in the cloud?

Answer 4

To manage and maintain security for third-party technologies and ensure adherence to necessary security standards.

Question 5

What is Infrastructure as Code (IaC)?

Answer 5

A method to define an application instance or a portion of cloud infrastructure as code, rather than as physical hardware.

Question 6

What is a key benefit of Infrastructure as Code (IaC) for managing cloud infrastructure?

Answer 6

The ability to easily build out and modify infrastructure, allowing for rapid deployment and consistent configuration changes.

Question 7

Explain the concept of serverless architecture.

Answer 7

It involves accessing individual functions of an application with less emphasis on the underlying operating system.

Question 8

How does a serverless architecture potentially save an organization time and money?

Answer 8

Application functions only run when needed, reducing continuous compute costs.

Question 9

Contrast a monolithic application with a microservice architecture.

Answer 9

A monolithic application runs as a single executable, while a microservice architecture breaks an application into separate services.

Question 10

How do Application Programming Interfaces (APIs) facilitate the use of microservices in a cloud environment?

Answer 10

They allow clients to programmatically control how an application works and communicate with microservices.

Question 11

What are two key benefits of using a microservice architecture in the cloud?

Answer 11

• Increased scalability
• Resilience
