Performance Efficiency Best Practices - AWS Well-Architected Framework Study Guide

Return to Well-Architected Framework Guide

Selection

• Use a data-driven approach to select architecture
• Data obtained through benchmarking or load testing will be required to optimize architecture
• Ask:
  • How do you select the best performing architecture?
• Four main resource types to consider:
  • Compute
    • Be aware of your requirements for workload performance and cost requirements
    • Compute is available in three forms: instances, containers, and functions
    • Ask: How do you select your compute solution?
  • Storage
    • Storage is available in three forms: object, block, and file
    • Ask: How do you select your storage solution?
  • Database
    • Choose from multiple purpose-built database engines including relational, key-value, document, in-memory, graph, time series, and ledger databases
    • Don’t need to worry about database management tasks
    • Consider the access patterns of your workload
    • Consider if other non-database solutions could solve the problem more efficiently
    • Ask: How do you select your database solution?
  • Network
    • Determine the workload requirements for bandwidth, latency, jitter, and throughput
    • Consider location when deploying your network
    • Use networking metrics to make changes to networking configuration as the workload evolves
    • Take advantage of Regions, placement groups, and edge services
    • Ask: How do you configure your networking solution?

Review

• Ensure that workload components are using the latest technologies and approaches to continually improve performance
• Continually evaluate and consider changes to your workload components
• Take advantage of the continual innovation at AWS (new Regions, edge locations, services, and features)
• Ask:
  • How do you evolve your workload to take advantage of new releases?

Monitoring

• Monitor workload performance to remediate any issues before they impact customers
• Use monitoring metrics to raise alarms when thresholds are breached
• Plan for game days to test your alarm solution and ensure that it correctly recognizes issues
• Ask:
  • How do you monitor your resources to ensure they are performing?

Tradeoffs

• Think about tradeoffs to ensure an optimal approach
• Collect and evaluate metrics to determine the impact of changes
• Measure the impacts to the system and to the end-user
• Ask:
  • How do you use tradeoffs to improve performance?
