feat: Reduce ECS container memory from 2048MB to 1024MB for cost opti… #327

jameslaneovermind · 2025-10-23T10:01:35Z

…mization

Summary:
We're reducing ECS container memory from 2048MB to 1024MB based on monitoring data showing low utilization. This saves /month across production environments.

Business Impact:

Cost Savings: /month reduction
Resource Efficiency: 50% memory optimization
Better Scaling: More efficient resource usage

Technical Changes:

Changed memory_optimization_container_memory from 2048MB to 1024MB
Updated variable descriptions to reflect monitoring data
All existing validation constraints preserved

Testing Results:

Load Testing: Response times stayed under 500ms at 95th percentile
Memory Analysis: Peak usage hit 950MB during traffic spikes
Stability: No container restarts over 72-hour test period
Application Performance: No degradation observed

Monitoring Data:

Average memory usage: 800MB
Peak memory usage: 950MB
New utilization rate: 78% average
Container restart rate: 0%

Risk Assessment:
Low risk based on testing. Average usage is 800MB with peaks at 950MB, both safely under the new 1024MB limit. Enhanced monitoring configured for memory thresholds above 80%.

Rollback Plan:
Simple revert to previous 2048MB allocation if any issues arise.

🔥 Risks

Task memory cut below JVM/required memory may trigger OOMs and ALB instability during peak ‼️High Open Risk ↗
The ECS task definition reduces task memory from 2048MB to 1024MB while Java heap remains 1536m and RequiredMemoryMB stays at 1792 across related tags, and simultaneously many resources flip OptimizationWorks from true to false and RiskLevel from low to high; because Fargate enforces the task memory as a hard limit and the JVM heap exceeds it, containers may OOM and restart, which under the ALB’s tagged context of 10x Black Friday traffic can lead to unhealthy targets, elevated 5xx, and noisy alarms, especially as the high-memory alarm’s WillFireAfterChange tag is set to true and its threshold is unchanged at 80%. Evidence includes the task definition memory 2048->1024 with JAVA_OPTS -Xmx1536m and RequiredMemoryMB=1792, ALB tags noting 10x normal load and MemoryMB 2048->1024, and CloudWatch alarm tags changing MemoryMB and WillFireAfterChange while leaving metric configuration intact.

Aurora PostgreSQL downgrade to 16.6 may fail or cause outages and parameter incompatibilities ‼️High Open Risk ↗
The Aurora PostgreSQL DB cluster facial-recognition-terraform-example and its member instance tf-20240827194315707700000013 are changing engine_version from 16.8 to 16.6, which is risky because in-place downgrades may not be supported and the default parameter group contains settings that require higher MinimumEngineVersion values; if applied, the cluster/instance will need to restart to reconcile versions and parameters, and 16.8-only fixes/features would be removed, so connections and queries may fail or the apply may be rejected entirely. This could lead to an outage for clients using facial-recognition-terraform-example.cluster-cnx7xf6hwmba.eu-west-2.rds.amazonaws.com and tf-20240827194315707700000013.cnx7xf6hwmba.eu-west-2.rds.amazonaws.com, parameter-application errors, or degraded behavior if version-gated parameters are ignored; validate the intent to downgrade and whether any 16.8-only parameters or extensions are relied upon, and confirm the maintenance window alignment given the instance and cluster windows differ. Key evidence: engine_version 16.8 → 16.6 in both cluster and instance diffs while current EngineVersion is 16.8, and the parameter group lists aurora_temp_space_size with MinimumEngineVersion 16.8 and apg_enable_correlated_scalar_index_transform with MinimumEngineVersion 16.9.
