Opportunity Description

DynamoDB offers two table classes: Standard and Standard-Infrequent Access (Standard-IA). The Standard-IA table class provides significant cost savings for tables where storage costs are the primary expense rather than read/write operations. By analyzing your table’s usage patterns, CloudFix can identify opportunities to transition tables to Standard-IA, potentially reducing storage costs by up to 60%.

How It Works

CloudFix’s DynamoDB Table Class Optimizer works in two phases:

Finder Phase

  • Discovers all DynamoDB tables across your AWS accounts and regions
  • Analyzes 30-day historical usage patterns for each table
  • Calculates potential cost savings by comparing storage and access costs between Standard and Standard-IA classes
  • Identifies tables where transitioning to Standard-IA would result in cost savings

Fixer Phase

  • Automatically transitions eligible tables to the Standard-IA class
  • Monitors table performance and usage patterns continuously
  • Can switch tables back to Standard class if usage patterns change
  • Respects AWS’s limit of two table class changes per 30 days

Key Benefits

  • Significant Cost Savings: Reduce storage costs by up to 60% for eligible tables
  • Zero Performance Impact: No changes to table performance, durability, or availability
  • Automated Optimization: Continuous monitoring and automatic transitions based on usage patterns
  • No Code Changes: Works with existing applications without requiring any code modifications
  • Bidirectional Optimization: Can switch tables between Standard and Standard-IA classes based on cost-effectiveness

Important Considerations

  • Table Class Changes: Limited to two changes per table within a 30-day period
  • Cost Analysis: Takes into account both storage and access costs to determine optimal table class
  • Reserved Capacity: Considers existing reserved capacity commitments when evaluating potential savings
  • Access Patterns: Standard-IA has higher costs for read/write operations but lower storage costs
  • Continuous Evaluation: CloudFix monitors usage patterns and adjusts table classes accordingly within AWS limits
