The activity spikes during Black Friday sales and the holiday season put significant stress on a major retailer's website. What feature of Cloud computing would resolve this problem?

Blockchain.

Explanation:

Blockchain is a type of database that stores information about an individual's activities and transactions in a block. It is different from a typical database by storing information in a block chained together for an individual and not spread across many databases.

This system of storing information allows digital databases to have a centralized 'block' for an individual, thereby allowing an easy and ready compartment of information for that person. By storing all information/ transactions of a person in one block and another person in another block, a blockchain makes it easier to 'list' the transaction history of people. Blockchain can also be known as a digital ledger for a person's transactions and keeps a record of the activities across the entire network. And it keeps the information in a systematic record thereby allowing easy and clear accessibility.
