- D. It connects on-premises data storage to the AWS Cloud.
<details markdown=1><summary markdown="span">Answer</summary>
Correct Answer: D
Explanation:
- Moving data to the cloud is not quite as simple as flipping a switch.
- For companies that have managed their own data centers or server rooms for decades, there are a few steps to consider --and it's not always wise to pull the plug on an internal infrastructure quite so quickly.
- If a startup uses on-premise business servers and then experiences unexpected growth, abandoning those servers doesn't make sense (even if the long-term plan is to do exactly that).
- AWS Storage Gateway is a way to bridge this gap for companies of any size.
- It's a hybrid storage option that connects on-premise storage including age-old tape backup systems to the cloud in a way that also provides one console to access all storage configurations.
