TESTD is hosted in a hybrid cloud infrastructure using
the Amazon Web Services (AWS)

infrastructure, Google, and TESTD's own dedicated
servers. By using a hybrid cloud system

instead of one source for data needs, TESTD can
deploy instances quickly and efficiently.

To provide blockchain capabilities, TESTD has chosen
to use the IBM Hyperledger fabric.

Hyperledger has become the standard worldwide for
global business transactions by major companies

in technology and other industries, allowing
companies to develop use-specific
components
while keeping access and identity controls fluent and
reliable.
