Cloud vendors are held to contractual obligations with specified metrics by:

The correct choice is SLAs, or Service Level Agreements. SLAs are formal contracts between cloud service providers and their customers that outline the specific performance metrics and standards the vendor agrees to uphold. This can include availability percentages, response times for support, and other crucial service parameters. By establishing these clear expectations, SLAs provide both parties with a mutual understanding of the minimum level of service required and the repercussions if those standards are not met. This makes SLAs essential in managing cloud services, as they help ensure accountability and can serve as a basis for conflict resolution regarding service delivery.

Other concepts, such as discipline, regulations, and law, while they may influence cloud service operations, do not provide the same type of direct contractual obligation with specified metrics as SLAs do. Regulations and laws may impose broader compliance requirements but lack the specificity and mutual agreement characteristic of SLAs.
