As the world's third largest economy, Japan has proven itself ready to maximize the opportunities from cloud computing, said the association.

"Despite some concerns around global risk due to earthquake fault lines and the efficiency of doing business, Japan has established itself with a set of known regulations and conditions that encourage cloud computing," the spokesperson noted.

The Cloud Readiness Index is designed to track Asia's progress toward a complete spectrum of cloud computing-based infrastructures and services, according to the association in a statement. By mapping the conditions and criteria required for successful implementation and uptake, the association said it aims to identify potential bottlenecks that could slow adoption and threaten Asia's digital future.
