The term cloud refers to the software and services that run on the internet instead of locally on your on-site server or computer. Adopting the cloud has helped companies to find alternative plans to cut costs and ensure their data and systems are available to their customers anywhere and at any time.
Traditionally, this was done by contracting with some provider to keep a physical second copy of your hardware, ready to go when your primary hardware has failed to operate. So cost savings can be realised, but you have to be careful about the expectations you set, especially in the early days.This is another common reason for cloud adoption. As your business grows and expands beyond your home borders it makes sense to have resources and services close to those new markets that you want to reach, it can be for regulatory reasons or maybe performance reasons.
But by adopting cloud from different providers, you can get access to that equipment in a matter of minutes and you can try your experiment and then shut down the equipment.
