7 Questions
What is a key difference between ephemeral storage and persistent storage?
Ephemeral storage is temporary, while persistent storage remains even when the virtual server is not attached.
How does pricing for cloud storage typically work?
Pricing is based on usage and performance requirements.
Which type of cloud storage is physically attached to the server?
File storage
What differentiates object storage from block and file storage?
Object storage is interacted with through an API.
Why does object storage suit warm and cold storage needs?
It offers low rates for data that is rarely accessed.
Which type of cloud storage underpins consumer solutions like iCloud, OneDrive, and Dropbox?
Object storage
In terms of cost-effectiveness, why does ephemeral storage differ from persistent storage?
Persistent storage disappears when the virtual server is not running.
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.
Dive into the world of cloud storage by exploring ephemeral and persistent storage types, their characteristics, performance, and pricing structures. Learn about the differences between object, block, and file storage options and how they cater to various data storage needs.
