Customer Responsibilities

Customer responsibilities are the part of the model that remain even when the platform becomes heavily managed. Data handling, identity policy, application behavior, configuration quality, and exposure decisions stay close to the customer’s business context because only the customer knows what the workload is allowed to do, who should access it, and what failure would mean.

This chapter turns that enduring customer layer into a practical checklist. The lessons cover data ownership and handling, identity and lifecycle decisions, workload and application security, and the misconfiguration risk that ties the whole chapter together. Those topics belong together because many cloud incidents do not come from missing provider controls. They come from customer-side decisions made quickly, inherited carelessly, or left unreviewed.

What To Carry Forward

• ownership follows business context as much as it follows technical implementation
• managed services remove some operational labor without removing customer decision rights
• configuration quality is often the place where customer responsibility becomes visible to attackers and auditors

Read this chapter when teams understand the provider side of the model but still underestimate how much responsibility remains with the customer in every service model.

In this section

• Data Ownership and Data Handling
  Data ownership is one of the most durable customer responsibilities in the cloud.
• Identity, Access, and User Lifecycle
  Identity and access are among the clearest customer-owned parts of the shared responsibility model.
• Application Logic and Workload Security
  Application logic and workload security stay with the customer even when the surrounding platform is highly managed.
• Configuration and Misconfiguration Risk
  Configuration risk is where the shared responsibility model most often fails in practice.
