Explanation
The TLS record protocol is the actual secure communications method for transmitting data; it's responsible for encrypting and authenticating packets throughout their transmission between the parties, and in some cases it also performs compression. The TLS handshake protocol is what negotiates and establishes the TLS connection between two parties and enables the secure communications channel to then handle data transmissions. Negotiation and transfer are not protocols under TLS.

Explanation:
With a typical BCDR solution, an organization would need some number of staff to quickly travel to the location of the BCDR site to configure systems and applications for recovery. With a cloud environment, everything is done over broad network access, with no need (or even possibility) to travel to a remote site at any time.
