Why infrastructure design underpins everything in HLD - Quick Recap

Recall & Review

beginner

What is infrastructure design in system architecture?

Infrastructure design is the planning and organization of the foundational technology components like servers, networks, storage, and data centers that support software applications and services.

beginner

Why is infrastructure design critical for system reliability?

Good infrastructure design ensures systems are stable, available, and can handle failures gracefully, which keeps services running smoothly without interruptions.

intermediate

How does infrastructure design affect system scalability?

Infrastructure design determines how easily a system can grow by adding more resources like servers or bandwidth to handle increased user demand without slowing down.

intermediate

What role does infrastructure design play in security?

Infrastructure design includes setting up secure networks, firewalls, and access controls that protect systems from unauthorized access and attacks.

beginner

Explain how poor infrastructure design can impact user experience.

If infrastructure is poorly designed, systems may be slow, unreliable, or frequently down, causing frustration and loss of trust from users.

What is the main purpose of infrastructure design in system architecture?

A To plan and organize foundational technology components

B To write application code

C To design user interfaces

D To create marketing strategies

Infrastructure design focuses on the foundational technology like servers and networks that support applications.

Which of the following is a direct benefit of good infrastructure design?

A Faster software development

B More social media followers

C Improved system reliability

D Better graphic design

Good infrastructure design improves system reliability by ensuring stability and uptime.

How does infrastructure design help with scalability?

A By adding more servers and resources easily

B By reducing the number of users

C By simplifying user interfaces

D By increasing marketing budgets

Infrastructure design allows systems to grow by adding resources like servers to handle more users.

What security aspect is part of infrastructure design?

A Creating password policies

B Writing encryption algorithms

C Designing user login pages

D Setting up firewalls and access controls

Infrastructure design includes setting up firewalls and access controls to protect systems.

What can happen if infrastructure design is poor?

A Users get more features

B Systems become slow and unreliable

C Development speed increases

D Marketing improves

Poor infrastructure design can cause slow, unreliable systems that frustrate users.
