Answers

A1. The ability to increase or decrease resources as needed.

Because scalability in cloud computing means that resources can be adjusted—expanded or reduced—based on demand, allowing for optimal performance and cost management.

A2. To distribute content closer to the user to improve load times.

CDNs strategically deploy servers in numerous locations worldwide, with major providers like Akamai operating over 275,000 servers in 130 countries as of 2021, enabling faster delivery and reduced latency for users globally.

A3. Infrastructure as a Service (IaaS)

Because it enables users to access and use virtualized computing resources over the internet, allowing them to pay only for what they use rather than owning physical hardware.

A4. Reduced latency for users accessing content

Because a CDN stores copies of content in multiple locations around the world, allowing users to access the closest server to them, which speeds up the delivery of that content.
