Cloud providers are more reluctant to change their default SLAs because their margins are based on providing basic services to many buyers. In some cases, however, customers can negotiate terms with their cloud providers. If the Service Provider is acquired by another company or merges with another company, the Customer may expect its SLA to remain in effect, but this may not be the case. The agreement may need to be renegotiated. Don`t make assumptions; Keep in mind, however, that the new owner does not want to alienate existing customers, so they can choose to abide by existing SLAs. Since the late 1980s, SLAs have been used by fixed telecommunications operators. SLAs are so common these days that large organizations have many different SLAs within the company itself. .
