## LINODE API V4 ARCHITECTURE & FOUNDATIONS

### 1.1 API Overview and Design Philosophy

The Linode API v4 represents a mature, production-grade REST API designed with developer experience as a primary concern. The API is now hosted on Akamai's technical documentation platform at `techdocs.akamai.com/linode-api/reference/api`.

**Core Architecture Principles**:
- RESTful design with standard HTTP methods (GET, POST, PUT, DELETE)
- JSON request and response format for all operations
- Bearer token authentication using personal access tokens
- Comprehensive error handling with meaningful HTTP status codes
- Extensive rate limiting information provided in response headers
- OpenAPI v3.0 specification for machine-readable API definitions

**API Endpoint Base URL**: `https://api.linode.com/v4`

### 1.2 API Versioning and Stability

Linode maintains strict API versioning to ensure backward compatibility. Current stable version is v4 with recent releases including:
- API v4.4.0 - Latest stable release
- API v4.2.4 - Previous stable
- v4.1.0 - Historical reference

The API follows semantic versioning principles, meaning:
- Major version changes (v3 to v4) introduce breaking changes
- Minor version increments add new features without breaking existing functionality
- Patch versions address bugs and security issues

### 1.3 Authentication Mechanism

All API requests require authentication via Bearer tokens (personal access tokens):

```
Authorization: Bearer <token-string>
```

**Token Management Features**:
- Generated from Akamai Cloud Manager portal
- Granular permission control for read/write operations
- Can be restricted to specific API operations
- Support for multiple tokens per account
- Token expiration management

**Authentication Example with cURL**:
```bash
curl -X POST https://api.linode.com/v4/linode/instances \
  -H "Authorization: Bearer <token-string>" \
  -H "Content-type: application/json" \
  -d '{
    "region": "us-east",
    "type": "g6-standard-2",
    "label": "my-instance"
  }'
```

### 1.4 Rate Limiting Strategy

Linode implements intelligent rate limiting with operation-specific thresholds:

**Standard Rate Limits**:
- GET-based paginated operations: 200 requests per minute
- POST/PUT/DELETE operations: Standard rate limit applies
- Response headers track usage: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`

**Service-Specific Rate Limits**:
- **Stats Endpoints**: 100 requests per minute per user
- **Object Storage**: 750 requests per second per user (highest allowance)
- **Support Tickets**: 2 requests per minute per user
- **DNS Operations**: Standard rate limit applies

**Rate Limit Headers Example**:
```
X-RateLimit-Limit: 200
X-RateLimit-Remaining: 195
X-RateLimit-Reset: 1605283734
```

**Price Includes**:
- Load balancing across unlimited backend nodes
- Unlimited configurations per NodeBalancer
- Full API and Cloud Manager management
- Dedicated load balancer IP address
- IPv6 support
- Hourly billing option available

### 4.3 NodeBalancer Architecture and Endpoints

**Core API Operations**:

```
GET /nodebalancers
  - List all NodeBalancers on account

POST /nodebalancers
  - Create new NodeBalancer

GET /nodebalancers/{id}
  - Retrieve specific NodeBalancer details

PUT /nodebalancers/{id}
  - Update NodeBalancer configuration

DELETE /nodebalancers/{id}
  - Delete NodeBalancer

GET /nodebalancers/{id}/configs
  - List all configurations for a NodeBalancer

POST /nodebalancers/{id}/configs
  - Create new configuration (new listening port/protocol)

GET /nodebalancers/{id}/configs/{configId}
  - Get configuration details

PUT /nodebalancers/{id}/configs/{configId}
  - Update configuration settings

DELETE /nodebalancers/{id}/configs/{configId}
  - Delete configuration

POST /nodebalancers/{id}/configs/{configId}/nodes
  - Add backend node to configuration

GET /nodebalancers/{id}/configs/{configId}/nodes
  - List all nodes in configuration

PUT /nodebalancers/{id}/configs/{configId}/nodes/{nodeId}
  - Update node settings

DELETE /nodebalancers/{id}/configs/{configId}/nodes/{nodeId}
  - Remove node from rotation
```

### 4.4 Load Balancing Algorithms

NodeBalancers support three distinct traffic distribution algorithms:

#### 4.4.1 Round Robin (Default)

**Behavior**: Allocates connections in weighted circular order

**Algorithm**:
```
Node Selection = (connection_count++ mod weighted_node_count)
```

**Use Cases**:
- Equally capable backend servers
- When connection distribution is more important than session persistence
- Stateless application backends

**Example**:
- 3 nodes (equal weight): Connections go to Node 1, Node 2, Node 3, Node 1, Node 2, Node 3...

#### 4.4.2 Least Connections

**Behavior**: Tracks each backend's active connections and routes new connections to server with fewest connections

**Algorithm**:
```
Selected Node = min(node.active_connections) among all nodes
```

**Use Cases**:
- Backends with varying performance characteristics
- Long-lived connections (websockets, persistent protocols)
- Connections with uneven duration

**Benefit**: Ensures load is distributed based on actual current load rather than time-based distribution

#### 4.4.3 Source IP Hash

**Behavior**: Uses client IP address to deterministically select backend node

**Algorithm**:
```
hash(client_ip) mod node_count = selected_node
```

**Sticky Session Guarantee**: Same client IP always routes to same backend (unless backend removed)

**Use Cases**:
- Applications requiring session affinity
- When application state is stored locally
- Avoiding distributed session management

### 4.5 Health Check Configuration

NodeBalancers perform both passive and active health monitoring:

#### 4.5.1 Passive Health Checks

**Operation**: Monitors actual traffic sent to backends

**Trigger Conditions**:
- Request timeout (connection fails)
- 5xx HTTP response (500, 502, 503, 504, etc.)
- Connection failure

**Supported Protocols**: TCP, HTTP, HTTPS

**When Triggered**:
- Backend automatically marked as "down"
- Removed from rotation immediately
- No new connections sent to failed node

#### 4.5.2 Active Health Checks

**Operation**: Proactively polls backends independent of traffic

**Check Methods**:
1. **Connection Check**: Opens TCP connection to health check port
   - Simplest method
   - Default check type
   - Verifies basic connectivity

2. **HTTP Check**: Sends HTTP GET request to specified path
   - Checks application-level health
   - Verifies HTTP response codes
   - Configurable check path

3. **HTTP Body Check**: Parses HTTP response body for regex match
   - Most comprehensive check
   - Verifies application state
   - Can check for specific response content

**Configurable Parameters**:

```
check_interval: 2-3600 seconds (default: 5)
  - How often health checks run

check_timeout: 1-30 seconds (default: 3)
  - How long to wait for check response

check_attempts: 1-30 (default: 2)
  - Failed checks before marking node down

check_path: String (default: "/")
  - URI path for HTTP health checks

check_body: Regex String
  - Response body pattern for validation
```

### 4.6 NodeBalancer Configuration Example

```python
# Python SDK Example - Create NodeBalancer with health monitoring
linode_client = LinodeClient(token='api-token')

# Create NodeBalancer
nb = linode_client.nodebalancers.create(
    label='production-lb',
    region='us-east',
    client_conn_throttle=20  # Limit connections per second
)

# Create configuration for HTTPS
config = nb.configs.create(
    port=443,
    protocol='https',
    algorithm='least_connections',
    stickiness='table',
    certificate_id='12345',
    ssl_commonname='example.com'
)

# Add health check configuration
config.update(
    check='http',
    check_interval=5,
    check_timeout=3,
    check_attempts=2,
    check_path='/health',
    check_body='healthy'
)

# Add backend nodes
for backend_ip in ['192.168.1.10', '192.168.1.11', '192.168.1.12']:
    config.nodes.create(
        address=f'{backend_ip}:8080',
        label=f'backend-{backend_ip}',
        weight=100,
        mode='accept'
    )
```

### 4.7 NodeBalancer Features and Limitations

**Advantages**:
- Layer 7 HTTP/HTTPS support with path-based routing
- Automatic failover based on health checks
- SSL/TLS termination reducing backend load
- Connection throttling to prevent backend overload
- Multiple backend nodes per configuration
- Real-time monitoring and statistics

**Considerations**:
- Regional load balancing (not global)
- Single point of failure (mitigated with Linode infrastructure redundancy)
- No DDoS protection (requires additional service)
- Per-request costs not a concern (flat monthly rate)

## LINODE'S TRANSPARENT PRICING MODEL ADVANTAGES

### 8.1 Pricing Philosophy

Linode's transparent pricing model directly addresses industry frustrations with AWS/GCP/Azure:

**Problem Statement**: Cloud customers struggle with unpredictable bills due to:
- Complex pricing dimensions (compute, storage, transfer, requests, etc.)
- Hidden charges for "premium" features
- Surprise bills from data transfer costs
- Difficulty forecasting costs
- Lack of clarity on what's included

**Linode Solution**: Simplified, bundled pricing with no hidden fees

### 8.2 Key Transparency Features

#### 8.2.1 Bundled Pricing

**What's Included in Every Plan**:
- CPU cores (shared or dedicated)
- RAM
- SSD storage
- Monthly data transfer allowance
- Backup service option
- API access

**Single Monthly Bill** for all included resources

#### 8.2.2 Hourly Billing Precision

```
Billing Formula: min(hourly_rate × hours_used, monthly_cap)
```

**Example Precision**:
- Spin up 1GB instance
- Use for 2 hours 15 minutes
- Delete instance
- Charge: $0.0075/hour × 2.25 hours = $0.0169 (not rounded up to $0.01)
- No wasted monthly charges

**Benefit**: Perfect for:
- Development and testing
- Temporary workloads
- Disaster recovery testing
- Autoscaling scenarios

#### 8.2.3 No Hidden Fees

**What You See Is What You Pay**:
- No "instance types" with surprise premium pricing
- No "availability zone" surcharges
- No "region premium" pricing variations
- No per-request API charges
- No "enhanced monitoring" upsells

**Rare Exception**: GPU instances cost more (clearly stated), but no other upsells

#### 8.2.4 Generous Transfer Allowances

**Included with Every Instance**:
- 1GB instance: 1TB/month transfer
- 4GB instance: 1TB/month transfer
- 16GB instance: 5TB/month transfer
- 48GB instance: 20TB/month transfer

**Real-World Impact**:
- Most small-to-medium deployments never pay transfer overage
- Overage rate is fair: $0.005/GB (vs AWS $0.09/GB)

#### 8.2.5 Predictable Forecasting

**With Linode**, predicting costs is straightforward:

```
Monthly Cost = (Instance Count × Instance Price)
             + (NodeBalancer Count × $10)
             + (Object Storage Size × Rate)
             + (DNS = $0)
             + (Optional: Backups × $2.50 per instance)
```

**Zero Variables**:
- No usage-based charges
- No surprise surge pricing
- No region premium variations
- No tier-based pricing jumping

### 8.3 Price Comparison: Transparency

#### 8.3.1 Understanding AWS Bill

**AWS Compute Bill for 4GB Instance** (t3.medium, 730 hours/month):
- Instance hours: $36.62/mo ✓
- EBS storage (100GB): $10.00/mo ✓
- Data transfer OUT to internet: $0.09 × 500GB = $45/mo ✓
- (Optional) Elastic IP: $3.60/mo (if not associated)
- CloudWatch monitoring: $3.50/mo (beyond free tier)
- VPC NAT Gateway: $32.45/mo + $0.045/GB (if used)
- **Total unpredictable**: Can range $36.62 to $200+/mo

**Linode Equivalent**:
- Linode 4GB: $24.00/mo
- All-inclusive: compute, storage, 1TB transfer
- Optional backups: $2.50/mo
- **Total**: $24-26.50/mo (predictable)

**Transparency advantage**: 70-85% easier to forecast with Linode

### 8.4 Community Appreciation of Transparent Pricing

**From Linode Community**:
- "Linode's straightforward pricing is refreshing"
- "No surprise $500 bills from data transfer like AWS"
