This architecture follows which AWS Well-Architected Framework best practice?
Secure the workload
Decouple infrastructure components
Design for failure
Think parallel
Explanations:
While securing workloads is important, this option does not directly relate to using Auto Scaling groups, which focus more on scaling and availability than security measures.
Decoupling infrastructure components refers to designing systems that are independent and modular. Auto Scaling groups manage web server instances but do not inherently address decoupling; they focus on managing instance counts based on demand.
Designing for failure is a key principle of resilience in cloud architecture. Auto Scaling groups help ensure that if an instance fails, new instances can be automatically launched to replace them, maintaining availability and minimizing downtime.
Thinking parallel refers to processing tasks in parallel rather than sequentially. While Auto Scaling can support parallel processing by adding instances, the core purpose of Auto Scaling is to manage capacity and availability, not specifically to encourage parallel execution of tasks.
