Data created in the cloud is not growing as fast as data stored in the cloud, and data creation at the edge is growing almost as fast as that in the cloud, according to IDC. Others have argued data creation increasingly moves to the edge over time.
Gartner, for example, projects that 75 percent of enterprise data will be created at the edge by about 2025.
“In 2020, 64.2 ZB of data was created or replicated, but less than two percent of this new data was saved and retained into 2021,” IDC says. Most of that new data was ephemeral (created or replicated primarily for the purpose of consumption) or temporarily cached and subsequently overwritten with newer data.IDC says.
The growth is mostly concentrated in public cloud facilities, though. IoT data (not including video surveillance cameras) is the fastest-growing data segment, followed by social media.
“The amount of digital data created over the next five years will be greater than twice the amount of data created since the advent of digital storage,” said said Dave Reinsel, IDC SVP.
IDC predicts global data creation and replication will experience a compound annual growth rate of 23 percent through 2025. Data storage will grow at a five-year CAGR of 19.2 percent. The installed base of storage capacity reached 6.7 ZB in 2020, IDC notes.
Archiving of data in the cloud also is increasing, others note.
