## PASS 2: PRIMARY ANALYSIS (20 min)

### Objective
Deep dive into core services: authentication, API rate limits, quotas, SDK capabilities, and integration points.

### 2.1 Authentication Mechanisms

#### IAM (Identity and Access Management)

**Access Key Credentials (Legacy)**
```
Access Key ID:     AKIAIOSFODNN7EXAMPLE
Secret Access Key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
```
- **Security Risk:** Long-term credentials, hard to rotate
- **Deprecation Status:** AWS recommends migration to roles
- **Use Case:** Older integrations, service accounts with restricted permissions
- **Best Practice:** Use only for non-interactive services, rotate every 90 days

**IAM Roles (Recommended)**
- **Temporary Credentials:** Automatically rotated every 15 minutes
- **No Secret Key Storage:** Credentials provided via STS (Security Token Service)
- **Trust Relationships:** Define which principals can assume the role
- **Inline/Managed Policies:** Attach permissions to roles
- **Service-Linked Roles:** AWS-managed roles for specific services

**Modern Authentication (2024+)**
- **OpenID Connect (OIDC):** For CI/CD pipelines (GitHub Actions, GitLab CI)
- **IAM Identity Center:** Centralized user management
- **CloudShell:** Temporary browser-based access
- **IDE Integration:** VS Code, JetBrains plugins with federated auth

#### API Gateway Authorization

**Resource-Based Policies**
- Control which principals can invoke the API
- JSON policy documents attached to API
- Support cross-account access

**API Keys**
- Simple key-based authentication
- Suitable for client applications
- Can throttle by API key

**Custom Authorizers (Lambda)**
- Lambda function validates tokens
- Useful for custom authentication logic
- Caches results for 5-3600 seconds

**Cognito User Pools**
- Full user management system
- JWT token validation
- Multi-factor authentication support

#### EC2 Security Groups
- Acts as virtual firewall for instances
- Stateful (return traffic automatically allowed)
- Define inbound/outbound rules
- Can reference other security groups

#### IAM Policy Structure

```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": ["s3:GetObject", "s3:PutObject"],
      "Resource": "arn:aws:s3:::my-bucket/*"
    },
    {
      "Effect": "Deny",
      "Action": "s3:DeleteObject",
      "Resource": "*"
    }
  ]
}
```

### 2.2 API Rate Limits and Quotas

#### EC2 Rate Limiting
- **Request Throttle:** 100 concurrent requests (per region)
- **Query Complexity:** Some operations count as multiple API calls
- **Retry Strategy:** Exponential backoff with jitter recommended
- **Error Code:** `RequestLimitExceeded` (HTTP 400)

#### S3 Rate Limiting
- **Request Rate:** 3,500 PUT/COPY/POST/DELETE per second per prefix
- **GET Rate:** 5,500 GET/HEAD per second per prefix
- **Partition Improvement:** Use random prefixes to distribute load
- **Multi-part Upload:** Can improve performance for large objects
- **Error Code:** `SlowDown` (HTTP 503)

#### Lambda Rate Limiting
- **Concurrent Execution:** Default 1,000, soft limit (adjustable)
- **Account Throttle:** Returns HTTP 429 when limit exceeded
- **Cold Start:** ~100-300ms for new instances
- **Memory-Performance:** More memory = faster CPU
- **Timeout Limits:** 15 minute max execution time

#### API Gateway Rate Limiting
- **Default Throttle:** 10,000 requests/second (burst: 5,000)
- **Per-API Throttle:** Can set custom limits per stage
- **Per-Client Throttle:** Using API keys for granular control
- **Usage Plans:** Define rate/quota per consumer
- **Error Code:** `TooManyRequestsException` (HTTP 429)

#### CloudWatch Rate Limiting
- **PutMetricData:** 1,000 API calls per second
- **DescribeMetrics:** 1 per second (pagination needed for large sets)
- **Logs:** 5 requests per second per log stream
- **Batch Operations:** Up to 1MB per request

#### RDS Rate Limiting
- **Connection Limit:** Depends on instance type (typically 1,000-40,000)
- **Parameter Group Changes:** 5 minute wait between modifications
- **Snapshot Copies:** 5 concurrent copies per destination region
- **Backup Window:** 30 minute maintenance window

#### SQS Rate Limiting
- **Requests:** 120,000 per minute per queue (300 messages/second)
- **Message Size:** 256 KB per message
- **Batch Send:** Up to 10 messages per call
- **Visibility Timeout:** 0 - 12 hours (default 30 seconds)

### 2.3 SDK Capabilities Comparison

#### AWS SDK for JavaScript (Node.js v3)

**Strengths:**
- Modular design (separate package per service)
- Full TypeScript support
- Automatic retry with exponential backoff
- S3 multipart upload helper
- Credentials provider chain (environment, IAM role, profile)

**Rate Limit Handling:**
```javascript
const { EC2Client, DescribeInstancesCommand } = require("@aws-sdk/client-ec2");

const client = new EC2Client({
  region: "us-east-1",
  retryMode: "adaptive",
  maxAttempts: 3
});

try {
  const command = new DescribeInstancesCommand({});
  const response = await client.send(command);
} catch (error) {
  if (error.name === "RequestLimitExceeded") {
    // Handle rate limit
  }
}
```

**S3 Multipart Upload:**
```javascript
const { Upload } = require("@aws-sdk/lib-storage");
const fs = require("fs");

const upload = new Upload({
  client: s3Client,
  params: {
    Bucket: "my-bucket",
    Key: "large-file.zip",
    Body: fs.createReadStream("large-file.zip")
  }
});

await upload.done();
```

#### AWS SDK for Python (Boto3)

**Strengths:**
- Highest-level abstractions
- Resource interface (object-oriented)
- Automatic credential discovery
- Session management for multi-account
- Comprehensive service coverage

**Rate Limit Handling:**
```python
import boto3
from botocore.exceptions import ClientError
from botocore.config import Config

config = Config(
    retries={'max_attempts': 3, 'mode': 'adaptive'},
    max_pool_connections=50
)

ec2 = boto3.client('ec2', region_name='us-east-1', config=config)

try:
    response = ec2.describe_instances()
except ClientError as e:
    if e.response['Error']['Code'] == 'RequestLimitExceeded':
        # Handle rate limit
        pass
```

**S3 Manager Example:**
```python
from boto3.s3.transfer import S3Transfer
import boto3

s3 = boto3.client('s3')
transfer = S3Transfer(s3)

# Automatically handles multipart upload
transfer.upload_file(
    '/tmp/large-file.zip',
    'my-bucket',
    'large-file.zip',
    extra_args={'ServerSideEncryption': 'AES256'}
)
```

#### AWS SDK for Go (v2)

**Strengths:**
- Built-in context support
- Excellent performance
- Strong type safety
- Service-specific helpers

**Rate Limit Handling:**
```go
package main

import (
    "context"
    "github.com/aws/aws-sdk-go-v2/aws"
    "github.com/aws/aws-sdk-go-v2/config"
    "github.com/aws/aws-sdk-go-v2/service/ec2"
)

func main() {
    cfg, _ := config.LoadDefaultConfig(context.TODO())
    client := ec2.NewFromConfig(cfg)

    output, err := client.DescribeInstances(
        context.TODO(),
        &ec2.DescribeInstancesInput{},
    )

    if err != nil {
        // Type assertion for specific errors
        if _, ok := err.(*types.RequestLimitExceeded); ok {
            // Handle rate limit
        }
    }
}
```

## PASS 3: RIGOR & REFINEMENT (15 min)

### Objective
Analyze edge cases, service limits, error handling patterns, and retry strategies.

### 3.1 Edge Cases and Failure Scenarios

#### Multi-Region Failures

**Scenario 1: Primary Region Outage**
- InfraFabric coordination must failover to secondary region
- Route53 health checks detect primary region unavailability
- Traffic redirected to secondary region database replicas
- Agent state must be replicated real-time (RDS read replica)
- **Solution:** Multi-region RDS replication with Route53 failover

**Scenario 2: Partial Service Degradation**
- Some services available, others degraded
- Example: EC2 quota exceeded but S3 still responding
- Agents need circuit breaker pattern
- **Solution:** CloudWatch alarms trigger fallback routes

**Scenario 3: API Rate Limiting Under Load**
- During agent swarm operations (50+ concurrent Lambda invocations)
- S3 GetObject calls exceed 5,500/sec per prefix
- SQS message batching insufficient
- **Solution:** Implement exponential backoff + request queuing in agent layer

**Scenario 4: Cross-Region Data Consistency**
- Agent in us-west-2 writes state, agent in eu-west-1 reads stale data
- RDS read replica lag: 1-2 seconds typical
- Critical for IF.bus message ordering
- **Solution:** Use DynamoDB global tables (synchronous) or application-level ordering

#### Service Limit Violations

**Lambda Concurrent Execution Exceeded**
- InfraFabric spawns 1,000+ agents (soft limit)
- Request returns HTTP 429
- **Mitigation:** Use Lambda reserved concurrency + SQS dead-letter queue

**API Gateway Throttle Exceeded**
- Default 10,000 req/sec insufficient for agent swarm
- **Mitigation:** Request service quota increase, use usage plans

**S3 Partition Key Limitations**
- All agents writing to `s3://if-state/{session}/` (same prefix)
- Limited to 3,500 PUTs per second
- **Mitigation:** Use hashed prefixes: `s3://if-state/{session-hash}/{timestamp}/`

### 3.2 Request Throttling Strategies

#### Exponential Backoff with Jitter

```python
import random
import time

def call_with_backoff(func, max_attempts=5):
    for attempt in range(max_attempts):
        try:
            return func()
        except ThrottlingException:
            wait_time = (2 ** attempt) + random.uniform(0, 1)
            print(f"Throttled. Waiting {wait_time:.2f}s...")
            time.sleep(wait_time)
    raise Exception("Max retries exceeded")
```

**Parameters:**
- Initial backoff: 1 second
- Maximum backoff: 32 seconds (2^5)
- Jitter: Random 0-1 second addition (prevents thundering herd)
- Maximum attempts: 3-5 for normal operations

#### Circuit Breaker Pattern

```python
class CircuitBreaker:
    def __init__(self, failure_threshold=5, timeout=60):
        self.failure_count = 0
        self.threshold = failure_threshold
        self.timeout = timeout
        self.last_failure_time = None
        self.state = "CLOSED"  # CLOSED -> OPEN -> HALF_OPEN -> CLOSED

    def call(self, func):
        if self.state == "OPEN":
            if time.time() - self.last_failure_time > self.timeout:
                self.state = "HALF_OPEN"
            else:
                raise CircuitBreakerOpen("Circuit is open")

        try:
            result = func()
            if self.state == "HALF_OPEN":
                self.state = "CLOSED"
                self.failure_count = 0
            return result
        except Exception as e:
            self.failure_count += 1
            self.last_failure_time = time.time()
            if self.failure_count >= self.threshold:
                self.state = "OPEN"
            raise
```

### 3.3 Error Handling Patterns

#### AWS SDK Error Types

**Retryable Errors:**
- `RequestLimitExceeded` (HTTP 400)
- `ServiceUnavailable` (HTTP 503)
- `ThrottlingException` (HTTP 400)
- `Timeout` errors
- `ConnectionError`

**Non-Retryable Errors:**
- `InvalidParameterException` (HTTP 400) - Fix code, not retry
- `AccessDenied` (HTTP 403) - Fix permissions, not retry
- `ResourceNotFoundException` (HTTP 404)
- `ValidationException` (HTTP 400)

#### Handling IAM Permission Errors

```python
try:
    response = s3.put_object(
        Bucket="protected-bucket",
        Key="file.txt",
        Body=b"data"
    )
except s3.exceptions.NoSuchBucket:
    # Handle missing bucket
    pass
except ClientError as e:
    if e.response['Error']['Code'] == 'AccessDenied':
        # Log permission issue, don't retry
        logger.error("Insufficient permissions to write to bucket")
        raise
    elif e.response['Error']['Code'] == 'RequestLimitExceeded':
        # Retry with backoff
        time.sleep(2 ** attempt)
        retry()
```

### 3.4 SDK Error Handling Best Practices

#### JavaScript (Node.js)
- Use async/await with try/catch
- Check `error.Code` property
- Implement request timeout (default: 0 = no timeout)
- Use `@aws-sdk/middleware-retry` for automatic retry

#### Python
- Use `botocore.exceptions.ClientError`
- Check `error.response['Error']['Code']`
- Configure retry behavior via `Config` object
- Use context managers for resource cleanup

#### Go
- Check error types with type assertion
- Use `smithy.GenericAPIError` for error details
- Implement context timeout
- Handle `context.DeadlineExceeded`

## PASS 4: CROSS-DOMAIN INTEGRATION (15 min)

### Objective
Cost analysis, security framework, compliance requirements, and monitoring strategy.

### 4.1 Cost Analysis for InfraFabric Workloads

#### Scenario: 10-Agent Haiku Swarm (NaviDocs Research Session)

**Architecture:**
- 10 Lambda functions (Haiku agents) executing in parallel
- Each agent: 512 MB memory, 5 minute execution
- 50 S3 API calls per agent (GetObject, PutObject)
- 100 SQS messages per session
- CloudWatch logs: 1 GB total
- 1 RDS query per agent for state storage

**Cost Breakdown:**

| Component | Usage | Price | Total |
|-----------|-------|-------|-------|
| Lambda (executions) | 10 × 1 = 10 | $0.20/1M | $0.000002 |
| Lambda (compute) | 10 × (512/1024 × 300) = 1,500 GB-s | $0.0000166667 | $0.025 |
| S3 Requests (GET) | 10 × 25 = 250 | $0.0004/1K | $0.0001 |
| S3 Requests (PUT) | 10 × 25 = 250 | $0.005/1K | $0.00125 |
| S3 Storage | 100 MB for 1 month | $0.000023 | ~$0 |
| SQS | 100 | $0.40/1M | $0.00004 |
| RDS (queries) | 10 | Incl. in instance | $0 |
| CloudWatch Logs | 1 GB ingestion | $0.50/GB | $0.50 |
| CloudWatch Logs | 1 GB storage | $0.03/GB/month | $0.03 |
| **Session Total** | | | **$0.556** |
| **Monthly (50 sessions)** | | | **$27.80** |
| **RDS Instance Base** | t3.small/730h | $0.023 | $16.79 |
| **S3 Storage (1 TB)** | Per month | $0.023 | $23.00 |
| **Route53** | 1 hosted zone | $0.50 | $0.50 |
| **Total Monthly** | | | **$68.09** |

**Cost Optimization Recommendations:**
1. Use Lambda reserved concurrency (20-30% discount)
2. Batch S3 operations (reduce request count by 50%)
3. Use CloudWatch Logs Insights instead of full ingestion for debug logs
4. Store agent outputs in S3 Intelligent-Tiering (auto-archive after 30 days)
5. Use EC2 Spot instances for stateless processing (70% savings)

#### Scenario: Production NaviDocs Deployment (100 Concurrent Users)

**Architecture:**
- 2 application servers (EC2 t3.medium)
- RDS PostgreSQL (db.t3.small, Multi-AZ)
- 1 TB S3 storage
- CloudFront distribution
- Route53 hosted zone
- CloudWatch monitoring
- API Gateway (REST API)

| Component | Unit Cost | Monthly Units | Total |

```

**Benefits:**
- No internet gateway exposure
- Reduced data exfiltration risk
- Lower NAT Gateway costs

#### Encryption at Rest

**S3 Object Encryption:**
- Server-Side Encryption (SSE-S3): AWS-managed keys
- Server-Side Encryption (SSE-KMS): Customer-managed keys (CMK)
- Requirement: Enable default encryption on all buckets

**RDS Database Encryption:**
- Encrypted at database creation (cannot enable/disable later)
- Uses AWS KMS for key management
- Automatic key rotation yearly
- Performance impact: <5% typically

**Configuration:**
```json
{
  "DBInstance": {
    "StorageEncrypted": true,
    "KmsKeyId": "arn:aws:kms:region:account:key/key-id",
    "Iops": 3000
  }
}
```

#### Identity and Access Management

**Principle of Least Privilege:**

Agent Role Policy Example:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "ReadSessionState",
      "Effect": "Allow",
      "Action": [
        "s3:GetObject",
        "s3:ListBucket"
      ],
      "Resource": [
        "arn:aws:s3:::if-state",
        "arn:aws:s3:::if-state/*"
      ]
    },
    {
      "Sid": "WriteSessionResults",
      "Effect": "Allow",
      "Action": "s3:PutObject",
      "Resource": "arn:aws:s3:::if-state/*/results/*"
    },
    {
      "Sid": "QueryDatabase",
      "Effect": "Allow",
      "Action": [
        "rds-db:connect"
      ],
      "Resource": "arn:aws:rds:*:account:db/coordination-db"
    }
  ]
}
```

#### Compliance Requirements

**SOC 2 Type II:**
- Encryption at rest and in transit ✅
- Audit logging (CloudTrail) ✅
- Access controls (IAM) ✅
- Multi-factor authentication for administrative access ✅
- Annual security assessment ✅

**HIPAA (if handling health data):**
- Business Associate Agreement (BAA) with AWS ✅
- Encryption of PHI both in transit and at rest ✅
- Audit controls and logging ✅
- Access controls and monitoring ✅
- Incident response procedures ✅

**GDPR (EU data residency):**
- Data localization in EU regions (eu-west-1, eu-central-1) ✅
- Data subject rights (access, deletion, portability) ✅
- Data Processing Agreement (DPA) ✅
- Privacy Impact Assessment (PIA) ✅

### 4.3 Monitoring and Observability

#### CloudWatch Metrics for InfraFabric

**Agent Performance Metrics:**
```
Namespace: InfraFabric/Agents
- Metric: ExecutionTime (ms)
- Metric: ErrorRate (%)
- Metric: TokensConsumed
- Metric: CompletionStatus (0=success, 1=failure)
Dimensions: [SessionId, AgentId, ModelType]
```

**Aggregation Strategy:**
- Per-agent metrics (granular troubleshooting)
- Per-session aggregate (session-level SLOs)
- Per-model aggregate (Haiku vs Sonnet cost analysis)

#### CloudWatch Logs Organization

**Log Groups:**
```
/infrafabric/sessions/{session-id}/agents/{agent-id}
/infrafabric/sessions/{session-id}/coordinator
/infrafabric/services/lambda
/infrafabric/services/rds
```

**Structured Logging Format (JSON):**
```json
{
  "timestamp": "2025-11-14T10:30:45.123Z",
  "session_id": "if://session/navidocs-research-2025-11-14",
  "agent_id": "if://agent/h21",
  "event_type": "agent_complete",
  "status": "success",
  "metrics": {
    "execution_time_ms": 45230,
    "tokens_input": 8192,
    "tokens_output": 3456,
    "cost_usd": 0.045
  },
  "trace_id": "x-amzn-trace-id: 1-63f6e5c3-52c6b1c5c1d6e1c1d6e1c1d6"
}
```

#### Alarms Configuration

**Agent Failure Alarm:**
```
MetricName: ErrorRate
Threshold: > 5%
Period: 5 minutes
Action: SNS notification, PagerDuty alert
```

**Session Stuck Alarm:**
```
MetricName: LastUpdate
Threshold: > 30 minutes without update
Period: 10 minutes
Action: SNS notification, auto-restart agent
```

**Cost Anomaly Detection:**
```
MetricName: DailyInvoice
Threshold: +30% from baseline
Period: 1 day
Action: SNS notification, budget alert
```

### 7.3 Documentation Gaps Identified

**Gap 1: Detailed Lambda Cold Start Analysis**
- **Issue:** AWS documentation doesn't provide cold start time guarantees
- **Impact:** Agent execution time variability not predictable
- **Mitigation:** Use Provisioned Concurrency for critical agents (+$0.015/hour per unit)

**Gap 2: Cross-Region Data Consistency Guarantees**
- **Issue:** RDS read replica lag not specified in SLA
- **Impact:** IF.bus message ordering may be inconsistent
- **Mitigation:** Use DynamoDB global tables for critical state

**Gap 3: Request Throttling Retry Strategy**
- **Issue:** AWS doesn't specify optimal exponential backoff parameters
- **Impact:** Rate limiting may cause unnecessary failures
- **Mitigation:** Use AWS SDK's adaptive retry mode (built-in)

**Gap 4: Agent Resource Isolation**
- **Issue:** Lambda doesn't provide memory/CPU guarantees across invocations
- **Impact:** Agent performance may vary unpredictably
- **Mitigation:** Use EC2 with reserved capacity for guaranteed performance

**Gap 5: Cost Forecasting Accuracy**
- **Issue:** AWS pricing calculator doesn't account for reserved capacity discounts
- **Impact:** Cost estimates may be inaccurate
- **Mitigation:** Use Compute Optimizer recommendations, monitor daily

### 7.4 Evidence Quality Assessment

   - SOC 2 Type II possible with proper configuration
   - HIPAA compliance if data minimization enforced
   - GDPR compliant with EU region selection
   - **Recommendation:** Implement security audit in Phase 2

4. **Multi-Region Failover Complex but Doable**
   - Requires 9/10 complexity rating, best saved for Phase 3
   - Route53 health checks provide good failover automation
   - RDS read replicas enable acceptable RPO
   - **Recommendation:** Start with single region, validate agent execution first

### Implementation Recommendation

**Recommended Approach: Phase 1 → Phase 2 → Phase 3**

1. **Weeks 1-2:** Deploy single-region MVP (US-East-1)
2. **Weeks 3-4:** Add Multi-AZ and monitoring
3. **Weeks 5-6:** Add secondary region with failover
4. **Beyond:** Optimize costs and add advanced features

**Estimated Timeline:** 5-6 weeks with 2-3 FTE
**Estimated Cost:** $3,000-5,000 development + $500-1,000 monthly operations
**Risk Level:** MEDIUM (well-defined tasks, good AWS documentation)
**Go/No-Go:** **GO AHEAD** - High confidence in successful implementation
