Data storage is shifting from endpoints to cloud, but edge storage also is growing, IDC data suggests. At the same time, the amount of real-time computing is growing, and some of that will consist of ultra-low latency, content delivery and bandwidth intensive use cases.
Looking only at data creation, which arguably is a different matter from data storage or computing operations, (solid lines in this illustration), endpoints are declining as a percentage of total data creation, while the core and edge continue to represent more of the data creation.
From a data storage perspective (dotted lines in this illustration), the amount of data being stored in endpoints will plummet as the core becomes the repository of choice for data of all types.
The chart does not specifically address computing workloads or instances, which might yield yet additional changes in workload processing (device, edge and core).
By 2024, IDC expects data stored in the core to be more than double the data stored in the endpoint, completely reversing the dynamic from 2010, for example.
Edge storage primarily will be used for latency-sensitive services and applications, it is reasonable to argue.
Real-time data represents 15 percent of activity in 2017, and might reach nearly 30 percent by 2025, IDC predicts.
