What is meant by on-premises data storage?

• Data is stored by a third-party provider on the internet

• Data is stored physically within the organisation’s infrastructure

• Data is stored temporarily in local cache

• Data is streamed from cloud applications in real time

Which of the following is a benefit of cloud storage?

• No internet connection required

What is a disadvantage of on-prem storage in terms of scalability?

• You can auto-scale with one click

• No ability to store structured data

• Scaling requires investment in hardware and time

• It's not compatible with hybrid systems

A hybrid solution allows an organisation to:
