Azure	99.99%	99.995%	50 ms	280 ms

Optimization Tips

1. Secret Caching

// Configure appropriate TTL based on secret rotation policy
let manager = AwsSecretsManager::new_with_cache_ttl(
    aws_config,
    Duration::from_secs(600)  // 10 minutes for less-frequently rotated secrets
).await?;

Impact: 100x throughput improvement, 99% latency reduction

2. Batch Operations

// Batch metrics export (50-100 optimal)
let metrics: Vec<Metric> = collect_metrics();
cloud_metrics.export_metrics(&metrics).await?;

// Batch log export (100-200 optimal)
let logs: Vec<LogEntry> = collect_logs();
cloud_logger.batch_log(&logs).await?;

Impact: 5-20x throughput improvement

3. Multipart Uploads

// Automatically used for files >5MB (AWS/GCP) or >4MB (Azure)
let large_file = vec![0u8; 50 * 1024 * 1024];  // 50 MB
storage.put_object("model.onnx", &large_file).await?;

Impact: 3-5x faster for large files

4. Connection Pooling

Already configured by default in all cloud SDKs:

AWS SDK: 50 connections per client
GCP SDK: 100 connections via gRPC multiplexing
Azure SDK: 50 connections per client

5. Regional Deployment

Deploy in same region as cloud resources:

# AWS
export AWS_REGION=us-east-1

# GCP
export GCP_REGION=us-central1

# Azure
export AZURE_LOCATION=eastus

Impact: 50-100ms latency reduction

6. Compression

Enable compression for large payloads:

// Automatically handled by cloud SDKs for responses >1 KB
// No configuration needed

Impact: 30-50% bandwidth reduction for text-heavy data

7. Async Concurrent Operations

use tokio::try_join;

// Execute cloud operations concurrently
let (secret, model, _) = try_join!(
    secret_manager.get_secret("api-key"),
    storage.get_object("model.onnx"),
    metrics.export_metric(&metric)
)?;

Impact: N operations in ~max(latencies) vs sum(latencies)
