A service account is what will most likely be created to run the batch processes that migrate the storage system and batch jobs from the local storage system to a public cloud provider. A service account is a special type of account that is used to perform automated tasks or operations on a system or service, such as running scripts, applications, or processes. A service account can provide benefits such as:

Security: A service account can have limited or specific permissions and roles that are required to perform the tasks or operations, which can prevent unauthorized or malicious access or actions.

Efficiency: A service account can run the tasks or operations without any human intervention or interaction, which can save time and effort.

Reliability: A service account can run the tasks or operations consistently and accurately, which can reduce errors or failures.
