What is the most cost-effective way for businesses to store their big data?

Cloud storage is generally considered the most cost-effective way for businesses to store their big data. With cloud storage, businesses can pay only for the storage space they need, and can easily scale up or down as their needs change. Additionally, cloud storage providers often offer a variety of pricing options, including pay-per-use, subscription-based, and reserved capacity plans. Cloud storage also eliminates the need for businesses to invest in and maintain their own on-premises storage infrastructure, which can be costly and time-consuming.
