Implement a buffer or throttle to manage demand

Effectively managing demand and supply resources is crucial for optimizing costs and maintaining performance. Implementing buffering and throttling mechanisms ensures that resources are utilized efficiently, reducing the risk of over-provisioning and enhancing application responsiveness during peak load times.

Best Practices

  • Design Adaptive Throttles: Create throttles that monitor the response times and client behavior. Implementing adaptive thresholds can dynamically adjust limits based on real-time usage data, ensuring optimal utilization without sacrificing performance.
  • Use Queuing for Buffering: Leverage queuing services to buffer requests that exceed processing limits. This ensures that higher demand is managed seamlessly, allowing you to defer processing without losing requests while minimizing wastage of computational resources.

Supporting Questions

  • What mechanisms are in place to adjust resources dynamically based on fluctuating demand?

Roles and Responsibilities

  • Cloud Architect: Responsible for designing and implementing architectures that include buffering and throttling strategies tailored to workload requirements.
  • DevOps Engineer: Tasks include monitoring resource usage and performance metrics to fine-tune application responsiveness through effective throttling and buffering.

Artifacts

  • Throttling Policy Document: A documented policy outlining the throttling limits and adaptive response strategies based on workload demand patterns.
  • Buffering Mechanism Configuration: Configuration files or scripts that detail the setup of buffering strategies, including service integrations and scaling policies.

Cloud Services

AWS

  • Amazon SQS: Amazon Simple Queue Service (SQS) can be utilized for solid buffering of requests, allowing for decoupled processing that can scale independently from the request input rate.
  • Amazon API Gateway: API Gateway offers throttling capabilities that help manage incoming requests, ensuring that resources can handle the load without degradation in performance.
