In search for future of cloud storage, researchers look to holographic storage solutions
Posted on November 11, 2020, Level beginner Resource Length medium
Data storage has always been a key tenet of compute, and with the massive growth in cloud compute, the demand for cloud data storage has opened an avenue for both revisiting prior technologies and developing new ones. It is projected that around 125 zettabytes of data will be generated annually by 2024, and storing this in a cost-effective way is going to be a big challenge.
