Object, Block, or File?
What is the difference between object, block and file storage, and how do you choose?
Practical scenario
A team stores user uploads on a block volume attached to a single instance, which is now full and cannot be scaled without downtime. Someone proposes moving the whole database onto object storage at the same time.
What it tests
Answer it out loud first. The guide below stays closed until you ask for it, on purpose.
- Whether the candidate knows the access model of each, not just the product names
- Whether they map workload requirements to the right primitive
- Whether they know what object storage cannot do
Reading a strong answer is not the same as producing one. Commit to what you would say, then compare.
