# crud-pricing - AWS Pricing CRUD Operations
|
||||||
|
|
||||||
|
**Single source of truth for all AWS pricing operations.**
|
||||||
|
|
||||||
|
## What It Does
|
||||||
|
|
||||||
|
This Lambda is the centralized CRUD service for AWS pricing data:
|
||||||
|
- ✅ **Get/Put pricing** in DynamoDB cache
|
||||||
|
- ✅ **Fetch from AWS Pricing API** (retail public prices)
|
||||||
|
- ✅ **Fetch from Cost Explorer** (account-specific with auto EDP/PPA!)
|
||||||
|
- ✅ **Access counting** for self-learning refresh
|
||||||
|
- ✅ **Query most-accessed instances** for smart 14-day refresh
|
||||||
|
|
||||||
|
## Why This Exists
|
||||||
|
|
||||||
|
**Problem:** Multiple lambdas touching pricing table = schema duplication
|
||||||
|
|
||||||
|
**Solution:** Single CRUD Lambda pattern
|
||||||
|
- All pricing operations go through one place
|
||||||
|
- Consistent schema enforcement
|
||||||
|
- Single place to evolve pricing logic
|
||||||
|
- Reusable across all components
|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
```
|
||||||
|
tool-pricing-query (MCP tool) }
|
||||||
|
enrichment-server-pricing (Lambda) } → crud-pricing (CRUD) → DynamoDB
|
||||||
|
tool-pricing-refresh (Scheduler) } ↓
|
||||||
|
AWS Pricing API
|
||||||
|
AWS Cost Explorer
|
||||||
|
```
|
||||||
|
|
||||||
|
**Used by:**
|
||||||
|
- `tool-pricing-query` - MCP tool wrapper for agents
|
||||||
|
- `enrichment-server-pricing` - Server pricing enrichment
|
||||||
|
- `tool-pricing-refresh` - 14-day automated refresh
|
||||||
|
|
||||||
|
**This Lambda is NOT registered with AgentCore** - it's internal CRUD only.
|
||||||
|
|
||||||
|
## Operations
|
||||||
|
|
||||||
|
### 1. Get - Retrieve pricing (with optional AWS fetch)

||||||
|
```
|
||||||
|
|
||||||
|
**Response:**

```
|
||||||
|
|
||||||

### 2. Put - Store pricing data
|
||||||
|
|
||||||
|
```json

|
||||||
|
"operation": {
|
||||||
|
"type": "put",
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1",

|
||||||
|
"pricingData": { /* PricingData object */ }
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. ListCommon - Get most-accessed instances
|
||||||
|
|
||||||
|

|
||||||
|
{
|
||||||
|
"operation": {
|
||||||

|
||||||
|
"limit": 50,
|
||||||
|
"minAccessCount": 5
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Response:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"instances": [
|
||||||
|
{
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1",
|
||||||
|
"accessCount": 347,
|
||||||
|
"lastAccessed": "2025-11-27T10:30:00Z",
|
||||||
|
"lastUpdated": "2025-11-20T00:00:00Z"
|
||||||
|
}
|
||||||
|
],
|
||||||
|
"count": 50
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Used by tool-pricing-refresh to discover common instances!**
|
||||||
|
|
||||||
|
### 4. IncrementAccess - Track usage
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"operation": {
|
||||||
|
"type": "incrementAccess",
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5. QueryAwsApi - Direct AWS Pricing API call
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"operation": {
|
||||||
|
"type": "queryAwsApi",
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### 6. QueryCostExplorer - Account-specific pricing (with EDP/PPA!)
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"operation": {
|
||||||
|
"type": "queryCostExplorer",
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1",
|
||||||
|
"awsAccountId": "123456789012",
|
||||||
|
"roleArn": "arn:aws:iam::123456789012:role/pathfinder-pricing-access"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**This automatically includes EDP/PPA discounts** by querying actual costs from the customer's account!
|
||||||
|
|
||||||
|
## Dual Pricing Model
|
||||||
|
|
||||||
|
### Retail Pricing (Public AWS List Prices)
|
||||||
|
|
||||||
|
**Cache Key:** `PK=INSTANCE#m6g.xlarge, SK=REGION#us-east-1#RETAIL`
|
||||||
|
|
||||||
|
**Source:** AWS Pricing API
|
||||||
|
|
||||||
|
**Use when:**
|
||||||
|
- No customer AWS account access
|
||||||
|
- Planning/estimates for new customers
|
||||||
|
- Baseline pricing comparisons
|
||||||
|
|
||||||
|
**TTL:** 30 days
|
||||||
|
|
||||||
|
### Account-Specific Pricing (Includes EDP/PPA Automatically!)
|
||||||
|
|
||||||
|
**Cache Key:** `PK=INSTANCE#m6g.xlarge, SK=REGION#us-east-1#ACCOUNT#123456789012`
|
||||||
|
|
||||||
|
**Source:** AWS Cost Explorer (from customer account)
|
||||||
|
|
||||||
|
**Use when:**
|
||||||
|
- Customer grants IAM role access
|
||||||
|
- Need actual cost projections
|
||||||
|
- Want automatic EDP/PPA discount detection
|
||||||
|
|
||||||
|
**TTL:** 7 days (more current)
|
||||||
|
|
||||||
|
**How EDP/PPA Auto-Detection Works:**
|
||||||
|
1. Assume IAM role into customer's AWS account (requires trust policy)
|
||||||
|
2. Query Cost Explorer for past 30 days of actual usage
|
||||||
|
3. Calculate average hourly rate from real costs
|
||||||
|
4. This rate automatically includes any EDP/PPA discounts!
|
||||||
|
5. No manual discount configuration needed
|
||||||
|
|
||||||
|
## DynamoDB Schema
|
||||||
|
|
||||||
|
### Pricing Items
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
{
|
||||||
|
// Keys
|
||||||
|
"PK": "INSTANCE#m6g.xlarge",
|
||||||
|
"SK": "REGION#us-east-1#RETAIL", // or "REGION#us-east-1#ACCOUNT#123456789012"
|
||||||
|
|
||||||
|
// GSI for access queries
|
||||||
|
"GSI1PK": "PRICING",
|
||||||
|
"accessCount": 127, // Incremented on each query
|
||||||
|
|
||||||
|
// Pricing data (stored as JSON)
|
||||||
|
"pricingData": "{...}", // Full PricingData struct serialized
|
||||||
|
|
||||||
|
// Metadata (for querying)
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1",
|
||||||
|
"pricingType": "retail",
|
||||||
|
"lastUpdated": "2025-11-27T00:00:00Z",
|
||||||
|
"lastAccessed": "2025-11-27T10:30:00Z",
|
||||||
|
"firstCached": "2025-11-01T08:00:00Z",
|
||||||
|
|
||||||
|
// TTL
|
||||||
|
"expiresAt": 1740614400 // 30 days for retail, 7 days for account-specific
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### GSI: AccessCountIndex
|
||||||
|
|
||||||
|
**Purpose:** Query most-accessed instances for refresh
|
||||||
|
|
||||||
|
**Keys:** `GSI1PK=PRICING, accessCount (range key, numeric)`
|
||||||
|
|
||||||
|
**Usage:**
|
||||||
|
```rust
|
||||||
|
// Get top 50 most-accessed instances
|
||||||
|
query()
|
||||||
|
.index_name("AccessCountIndex")
|
||||||
|
.key_condition_expression("GSI1PK = :pk")
|
||||||
|
.scan_index_forward(false) // Descending
|
||||||
|
.limit(50)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Self-Learning Refresh Strategy
|
||||||
|
|
||||||
|
**How it works:**
|
||||||
|
|
||||||
|
1. **Enrichment drives caching**
|
||||||
|
- Server created → enrichment queries pricing
|
||||||
|
- Cache miss → fetch from AWS API → cache for 30 days
|
||||||
|
- Cache hit → fast response
|
||||||
|
|
||||||
|
2. **Access counting tracks popularity**
|
||||||
|
- Every query increments `accessCount`
|
||||||
|
- Popular instances accumulate high counts
|
||||||
|
- Unpopular instances stay at low counts
|
||||||
|
|
||||||
|
3. **14-day refresh uses actual patterns**
|
||||||
|
- Query top 50 by `accessCount`
|
||||||
|
- Refresh only what's actually being used
|
||||||
|
- Adapts automatically as usage changes
|
||||||
|
|
||||||
|
**Result:** Cache reflects real usage patterns, no hardcoded lists!
|
||||||
|
|
||||||
|
## IAM Requirements
|
||||||
|
|
||||||
|
### This Lambda Needs:
|
||||||
|
|
||||||
|
**DynamoDB:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|

## Integration Examples
|
||||||
|
|
||||||
|
### From tool-pricing-query
|
||||||
|
|
||||||
|
```rust
|
||||||
|
// tool-pricing-query calls crud-pricing instead of direct DynamoDB
|
||||||
|
|
||||||
|
let payload = json!({
|
||||||
|
"operation": {
|
||||||
|
"type": "get",
|
||||||
|
"instanceType": instance_type,
|
||||||
|
"region": region,
|
||||||
|
"pricingType": "retail",
|
||||||
|
"fetchIfMissing": true
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
let result = lambda_client
|
||||||
|
.invoke()
|
||||||
|
.function_name("airun-pathfinder-crud-pricing-dev")
|
||||||
|
.payload(Blob::new(serde_json::to_vec(&payload)?))
|
||||||
|
.send()
|
||||||
|
.await?;
|
||||||
|
```
|
||||||
|
|
||||||
|
### From enrichment-server-pricing
|
||||||
|
|
||||||
|
```rust
|
||||||
|
// Enrichment lambda calls crud-pricing to get pricing
|
||||||
|
|
||||||
|
let payload = json!({
|
||||||
|
"operation": {
|
||||||
|
"type": "get",
|
||||||
|
"instanceType": "m6g.xlarge",
|
||||||
|
"region": "us-east-1",
|
||||||
|
"pricingType": "accountSpecific",
|
||||||
|
"awsAccountId": project.aws_account_id,
|
||||||
|
"fetchIfMissing": true
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
let pricing = invoke_crud_pricing(payload).await?;
|
||||||
|
```
|
||||||
|
|
||||||
|
### From tool-pricing-refresh
|
||||||
|
|
||||||
|
```rust
|
||||||
|
// Refresh lambda discovers common instances
|
||||||
|
|
||||||
|
// Step 1: Get most-accessed
|
||||||
|
let common = invoke_crud_pricing(json!({
|
||||||
|
"operation": {
|
||||||
|
"type": "listCommon",
|
||||||
|
"limit": 50,
|
||||||
|
"minAccessCount": 5
|
||||||
|
}
|
||||||
|
})).await?;
|
||||||
|
|
||||||
|
// Step 2: Refresh each one
|
||||||
|
for instance in common.instances {
|
||||||
|
invoke_crud_pricing(json!({
|
||||||
|
"operation": {
|
||||||
|
"type": "get",
|
||||||
|
"instanceType": instance.instanceType,
|
||||||
|
"region": instance.region,
|
||||||
|
"pricingType": "retail",
|
||||||
|
"fetchIfMissing": true // Forces refresh
|
||||||
|
}
|
||||||
|
})).await?;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Cache Strategy
|
||||||
|
|
||||||
|
### Retail Pricing
|
||||||
|
- **TTL:** 30 days
|
||||||
|
- **Refresh:** 14-day automatic (top 50 instances)
|
||||||
|
- **Coverage:** All instance types (on-demand fetch)
|
||||||
|
|
||||||
|
### Account-Specific Pricing
|
||||||
|
- **TTL:** 7 days (shorter for more current costs)
|
||||||
|
- **Refresh:** Not automatic (requires account access)
|
||||||
|
- **Coverage:** Only instances with usage in customer account
|
||||||
|
|
||||||
|
### Access Counting
|
||||||
|
- Incremented on every Get operation
|
||||||
|
- Powers self-learning refresh
|
||||||
|
- GSI allows efficient queries
|
||||||
|
|
||||||
|
## Pricing API Details
|
||||||
|
|
||||||
|
### AWS Pricing API (Retail)
|
||||||
|
|
||||||
|
**What we get:**
|
||||||
|
- OnDemand hourly/monthly rates
|
||||||
|
- Reserved pricing (Standard/Convertible, 1yr/3yr, all payment options)
|
||||||
|
- Instance specs (vCPUs, memory, architecture)
|
||||||
|
|
||||||
|
**What we DON'T get:**
|
||||||
|
- Spot pricing (need EC2 Spot Price API)
|
||||||
|
- Customer-specific discounts (need Cost Explorer)
|
||||||
|
|
||||||
|
**Rate Limits:**
|
||||||
|
- 1,000,000 requests/month free
|
||||||
|
- Then $0.005 per 1,000 requests
|
||||||
|
- Our usage: ~70 requests/month (essentially free)
|
||||||
|
|
||||||
|
### AWS Cost Explorer (Account-Specific)
|
||||||
|
|
||||||
|
**What we get:**
|
||||||
|
- Actual hourly costs from customer's account
|
||||||
|
- Automatically includes EDP/PPA discounts!
|
||||||
|
- Real usage-based pricing
|
||||||
|
|
||||||
|
**What we DON'T get:**
|
||||||
|
- Instance specs (we fetch separately from Pricing API)
|
||||||
|
- Reserved/Spot breakdowns (just blended costs)
|
||||||
|
|
||||||
|
**Requirements:**
|
||||||
|
- Must assume role into customer account
|
||||||
|
- Customer must have Cost Explorer enabled
|
||||||
|
- Needs 30 days of usage history
|
||||||
|
|
||||||
|
## Error Handling
|
||||||
|
|
||||||
|
| Error | Cause | Mitigation |
|
||||||
|
|-------|-------|------------|
|
||||||
|
| `Pricing not found and fetch_if_missing=false` | Cache miss, no fetch | Set `fetchIfMissing=true` |
|
||||||
|
| `AWS Pricing API call failed` | API throttling, network issue | Retry with exponential backoff |
|
||||||
|
| `Failed to assume role` | IAM permissions, invalid role ARN | Check trust policy and role exists |
|
||||||
|
| `No usage data found` | No historical usage in account | Fall back to retail pricing |
|
||||||
|
| `No pricing found for instance` | Invalid instance type | Validate instance type exists |
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
**Expected latencies:**
|
||||||
|
- Cache hit: 10-20ms (DynamoDB query)
|
||||||
|
- Cache miss (Pricing API): 2-3 seconds (API call + parse)
|
||||||
|
- Cost Explorer: 3-5 seconds (assume role + API call)
|
||||||
|
|
||||||
|
**Access count update:** Async (doesn't add latency)
|
||||||
|
|
||||||
|
## Code Structure
|
||||||
|
|
||||||
|
```
|
||||||
|
src/
|
||||||
|
├── main.rs # Lambda handler and operation router
|
||||||
|
├── models.rs # Data types and schemas
|
||||||
|
├── db.rs # DynamoDB CRUD operations
|
||||||
|
├── aws_pricing.rs # AWS Pricing API client
|
||||||
|
└── cost_explorer.rs # Cost Explorer client (EDP/PPA detection)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Total:** ~1,100 lines of well-structured Rust
|
||||||
|
|
||||||
|
## Testing Strategy
|
||||||
|
|
||||||
|
**Unit Tests:**
|
||||||
|
- [ ] Test all DynamoDB operations
|
||||||
|
- [ ] Test pricing API response parsing
|
||||||
|
- [ ] Test Cost Explorer response parsing
|
||||||
|
- [ ] Test key generation (retail vs account-specific)
|
||||||
|
- [ ] Test expiration logic
|
||||||
|
- [ ] Test access counting
|
||||||
|
|
||||||
|
**Integration Tests:**
|
||||||
|
- [ ] Test full Get operation (cache miss → fetch → cache)
|
||||||
|
- [ ] Test access count increment
|
||||||
|
- [ ] Test ListCommon with various filters
|
||||||
|
- [ ] Test account-specific pricing flow
|
||||||
|
|
||||||
|
## Monitoring
|
||||||
|
|
||||||
|
**CloudWatch Metrics to Add:**
|
||||||
|
|
||||||
|
```rust
|
||||||
|
// Custom metrics
|
||||||
|
putMetric("CrudPricing", {
|
||||||
|
"CacheHitRate": hits / total * 100,
|
||||||
|
"AvgResponseTime": avg_latency_ms,
|
||||||
|
"ApiCallCount": api_calls,
|
||||||
|
"AccessCountUpdates": count_updates,
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
**Alarms:**
|
||||||
|
- High cache miss rate (>20%)
|
||||||
|
- Slow response time (>5s)
|
||||||
|
- API failures (>5 in 5 minutes)
|
||||||
|
|
||||||
|
## Related Components
|
||||||
|
|
||||||
|
- `tool-pricing-query` - MCP tool that wraps this CRUD service
|
||||||
|
- `enrichment-server-pricing` - Uses this to get pricing during enrichment
|
||||||
|
- `tool-pricing-refresh` - Uses ListCommon to discover instances to refresh
|
||||||
|
- `pathfinder-dev-pricing` - DynamoDB table managed by this service
|
||||||
|
|
||||||
|
## Next Steps
|
||||||
|
|
||||||
|
After deployment:
|
||||||
|
1. Update `tool-pricing-query` to use crud-pricing (remove direct DynamoDB access)
|
||||||
|
2. Create `enrichment-server-pricing` that uses crud-pricing
|
||||||
|
3. Create `tool-pricing-refresh` that uses ListCommon operation
|
||||||
|
4. Update DynamoDB table with AccessCountIndex GSI
|
||||||
