Questions and Answers

What is a key difference between ephemeral storage and persistent storage?

Ephemeral storage is billed per gigabyte per month, while persistent storage is interacted with through an API.

Ephemeral storage is physically attached to the host, while persistent storage is high performing.

Ephemeral storage is suitable for warm and cold storage needs, while persistent storage is cost-effective due to its transient nature.

Ephemeral storage is temporary, while persistent storage remains even when the virtual server is not attached. (correct)

How does pricing for cloud storage typically work?

Pricing is fixed monthly regardless of usage.

Pricing is based on usage and performance requirements. (correct)

Pricing is free for all users with cloud storage accounts.

Pricing only depends on the type of storage used.

Study Notes

Cloud storage can be categorized into two main types: ephemeral storage and persistent storage.
Ephemeral storage is temporary and exists only as long as the virtual server it's attached to is running.
Ephemeral storage is high performing, physically attached to the host, and cost-effective due to its transient nature.
Persistent storage, on the other hand, remains even when the virtual server is not attached and comes in three main types: block, file, and object storage.
Block storage attaches to the virtual server through the hypervisor, file storage is directly attached to the server, and object storage is interacted with through an API.
Pricing for cloud storage is based on usage (billed per gigabyte per month) and performance requirements (higher performance needs result in higher costs).
Object storage is suitable for warm and cold storage needs, offering low rates for data that is rarely accessed but needs to be retained.
Consumer cloud storage solutions like iCloud, OneDrive, and Dropbox are underpinned by object storage for cost-effectiveness and suitability for lower performance needs.
