Amazon ECS manages placement and service operation of containers in an AWS-native orchestration model.
Lightsail offers simplified VPS plans with predictable bundles for straightforward applications.
Lambda executes functions on demand and manages underlying compute for the customer.
A compliance lead needs a timeline of security group rule configuration changes.
Which AWS concept, service, or approach best meets the need described?
AWS Config records supported resource configurations and evaluates them against configured compliance rules. For the described requirement, use AWS Config for resource configuration history and rule compliance evaluation.
Audit Manager helps gather evidence against assessment controls but does not certify a customer's entire workload.
CloudWatch provides metric visibility and alarm reactions; it is not a replacement for CloudTrail API audit logs.
Provider reports describe AWS controls, whereas application-specific obligations still need customer evidence.
An application owner asks for a dashboard of CPU utilization and alarm thresholds.
Which observation would best confirm that the intended cloud outcome is being achieved?

Inspector analyzes supported workloads for exposure and software vulnerabilities, not user login events.
Trusted Advisor evaluates selected account checks and is not the same as a complete security audit.
A ticketing site has predictable low traffic during weekdays but severe demand spikes at concert launches.
Which observation would best confirm that the intended cloud outcome is being achieved?
Elasticity aligns provisioned resources with current need instead of maintaining permanent peak-sized local capacity.
Regional AWS infrastructure lets customers choose appropriate geographic placement subject to service availability and compliance.
Metered cloud consumption lowers initial capital outlay and supports experiments with uncertain future demand.
Many AWS services can be used without buying underlying equipment; cost commitments vary by pricing option.
An analytics team runs an occasional monthly batch task and otherwise leaves dedicated machines unused.
Which observation would best confirm that the intended cloud outcome is being achieved?
Elastic self-service consumption can improve efficiency when unnecessary resources are stopped or released.
Variable pricing links many cloud expenses to provisioned capacity and consumption while owned equipment has upfront fixed costs.
Availability Zones are isolated fault locations within a Region and reduce dependency on one data-center location.
Metered cloud consumption lowers initial capital outlay and supports experiments with uncertain future demand.
A web application uses several healthy instances and wants incoming requests spread among them.
Which AWS concept, service, or approach best meets the need described?
A load balancer forwards requests to configured healthy application targets and supports availability. For the described requirement, use Elastic Load Balancing to distribute eligible requests across targets.
