A city board asks whether the AWS shared responsibility model always splits security work exactly 50/50 between AWS and the city. Which response is accurate?
Select an answer to reveal the explanation.
Short Explanation
Think of renting a bare room versus a furnished apartment with utilities included — your chores change with what you rented. Shared responsibility is not a locked 50/50 pie chart. EC2 leaves more OS work with the customer; managed and serverless services shift more of that layer to AWS.
Full Explanation
The shared responsibility model changes with the service abstraction. On Amazon EC2, customers typically manage the guest operating system and applications; on Amazon RDS or AWS Lambda, AWS operates more of the infrastructure and runtime layers while customers still control data, identity, and configuration. A fixed 50/50 split is incorrect, and migrating to AWS never removes all customer security duties.
