A media company owns physical servers sized for its historical peak holiday traffic. For the other eleven months of the year, those servers run at roughly 15% utilization, yet the company still pays for 100% of the hardware, power, and floor space. Which AWS Cloud advantage MOST directly addresses this specific inefficiency?
Stop guessing capacity lets the company use elasticity and auto scaling to match compute supply to actual demand in real time instead of over-provisioning hardware for a rare peak, eliminating the idle capacity described.
During a cloud adoption assessment, a company identifies a gap: employees lack the cloud skills needed to operate new workloads, and there is no formal training or organizational change management plan in place. According to the AWS Cloud Adoption Framework (CAF), which perspective is this gap MOST associated with?
The People Perspective of the AWS CAF focuses on people development, training, staffing, and organizational change management needed to adopt cloud successfully.
A finance team compares an on-premises deployment to AWS by looking only at the purchase price of servers versus AWS On-Demand hourly rates, and concludes on-premises is cheaper. Which factor is this analysis MOST likely failing to include that a proper Total Cost of Ownership (TCO) comparison requires?
TCO analysis must include indirect on-premises costs like power, cooling, real estate, and staff needed to maintain hardware, not just the sticker price of hardware compared to cloud rates.
An online ticket retailer's application automatically adds compute capacity in the minutes before a popular concert's tickets go on sale, then automatically removes that capacity a few hours later once demand drops. Which cloud characteristic does this BEST demonstrate?
Elasticity is the ability to automatically grow AND shrink resources in response to demand, matching capacity to load in near real time, as shown by both scaling up and back down.
A development team redesigns a monolithic order-processing application into separate services connected by Amazon SQS queues, so that if the inventory service fails temporarily, the order-intake service can continue accepting orders without being blocked. Which cloud architecture design principle does this redesign demonstrate?
Decoupling separates application components so they interact through queues or APIs rather than direct dependencies, allowing one component's failure or slowdown to not directly impact others — a core Well-Architected design principle.
A company designs its workload so that if an Availability Zone becomes unavailable, automated processes detect the failure and route traffic to healthy resources in another Availability Zone without manual intervention. This design decision primarily supports which AWS Well-Architected Framework pillar?
The Reliability pillar focuses on a workload's ability to recover from infrastructure or service disruptions automatically, including failover across Availability Zones.
