Data Gravity increases the requirements of regional data centers


Dave McCrory coined the term Data Gravity in 2010. Data gravity is the ability of bodies of data to attract applications, services and other data. Gravity is manifested in this metaphor in how software, services, and business logic are physically brought closer to data in relation to their mass (the amount of data). The larger the amount of data, the more applications, services and other data will be attracted to this data. Data gravity is often used to describe how more and more data moves to the cloud (large hyperscale data centers).

Digital Realty, which provides global data center, co-location and connectivity solutions, recently released the results of its Data Gravity Index. Digital Realty conducted research between August 2019 and August 2020 and relied on more than a dozen external data sources to create this index, from the World Economic Forum and the United Nations to global consulting and market research firms. This index helped the company plot data creation intensity, data expansion, available bandwidth, and latency to provide a data intensity metric for multiple geographic locations for G2000 companies, as shown below.

Data gravity intensity, measured in gigabytes per second, is projected to grow at an average annual growth rate (CAGR) of 139% globally through 2024 as data management drives global companies to increase their digital infrastructure capacity to aggregate, store and store the data manage most of the world’s data. This increase in intensity is shown in the following figure.

By 2024, Digital Realty estimates that G2000 Enterprises will generate data at a rate of 1.1 EB / s (exabytes per second) and require 15.6 ZB (zettabytes) of additional data storage per year. The following numbers show a CAGR of 28% data creation per second and a CAGR of 53% data storage from 2020 to 2024.

Data gravity intensity in the Europe, Middle East and Africa (EMEA), Asia and Pacific (APAC), and North America regions is expected to more than double annually through 2024. Data gravity in the 21 subways analyzed in this study . In the 21 metropolises, the data gravity intensity in EMEA and APAC is increasing faster than in North America. Data gravity intensity in EMEA will be eliminated almost twice as fast as in North America in 2024.

The following figure shows 2020 compared to the forecast data gravity intensity for 2024 for the 21 metropolitan regions. The six fastest growing metros in terms of data gravity intensity by 2024 are expected to be Singapore, Hong Kong, Dallas, Sydney, Seattle and Tokyo. Metro-to-metro data flows will play a huge role in increasing data gravity intensity, with London to Amsterdam having the largest data flows in 2020 and forecast for 2024, followed by Paris to London.

Digital Realty’s Data Gravity Index for G2000 companies shows the growing impact of data gravity on regions and metropolitan areas and its impact on data creation and storage capacity from 2020 to 2024.
