PERF01-BP03 Factor cost into architectural decisions
Factor cost into your architectural decisions to improve resource utilization and performance efficiency of your cloud workload. When you are aware of the cost implications of your cloud workload, you are more likely to leverage efficient resources and reduce wasteful practices.
Common anti-patterns:
-
You only use one family of instances.
-
You do not evaluate licensed solutions against open-source solutions.
-
You do not define storage lifecycle policies.
-
You do not review new services and features of the AWS Cloud.
-
You only use block storage.
Benefits of establishing this best practice: Factoring cost into your decision making allows you to use more efficient resources and explore other investments.
Level of risk exposed if this best practice is not established: Medium
Implementation guidance
Optimizing workloads for cost can improve resource utilization and avoid waste in a cloud workload. Factoring cost into architectural decisions usually includes right-sizing workload components and enabling elasticity, which results in improved cloud workload performance efficiency.
Implementation steps
-
Establish cost objectives like budget limits for your cloud workload.
-
Identify the key components (like instances and storage) that drive cost of your workload. You can use AWS Pricing Calculator
and AWS Cost Explorer to identify key cost drivers in your workload. -
Understand pricing models
in the cloud, such as On-Demand, Reserved Instances, Savings Plans, and Spot Instances. -
Use Well-Architected cost optimization best practices to optimize these key components for cost.
-
Continually monitor and analyze cost to identify cost optimization opportunities in your workload.
-
Use AWS Budgets
to get alerts for unacceptable costs. -
Use AWS Compute Optimizer
or AWS Trusted Advisor to get cost optimization recommendations. -
Use AWS Cost Anomaly Detection
to get automated cost anomaly detection and root cause analysis.
