✅ Pre-Deployment Checklist

Essential Requirements

Before deploying to production, ensure you have:

✅ API Keys Secured - Stored in environment variables or secrets manager
✅ Error Handling - Comprehensive try-catch blocks around AI calls
✅ Rate Limiting - Client-side request throttling implemented
✅ Monitoring - Logging and alerting configured
✅ Fallback Strategy - Secondary provider or graceful degradation
✅ Timeout Configuration - Appropriate timeouts for your use case
✅ Cost Limits - Budget alerts and usage tracking
✅ Health Checks - Endpoints to verify service availability
✅ Load Testing - Performance validated under expected load
✅ Backup Provider - Alternative AI provider configured

Configuration Validation

// Validate configuration on startup
function validateAIConfiguration() {
    required = [
        "OPENAI_API_KEY",
        "CLAUDE_API_KEY",  // Backup provider
        "AI_TIMEOUT_SECONDS",
        "AI_MAX_RETRIES"
    ]

    missing = []
    for ( key in required ) {
        if ( isNull( getSystemSetting( key, "" ) ) || getSystemSetting( key ) == "" ) {
            missing.append( key )
        }
    }

    if ( !missing.isEmpty() ) {
        throw "Missing required AI configuration: #missing.toList()#"
    }

    writeLog( "AI configuration validated successfully" )
}

// Run on application start
BoxAnnounce( "onApplicationStart", {
    listener: validateAIConfiguration
} )

⚙️ Configuration Management

Environment-Based Configuration

Separate configs per environment:

// config/ai-config.bx
class {
    function getAIConfig() {
        var env = getSystemSetting( "ENVIRONMENT", "production" )

        var configs = {
            "development": {
                provider: "ollama",           // Free for dev
                model: "llama3.2:3b",
                timeout: 30,
                retries: 1,
                logLevel: "DEBUG"
            },
            "staging": {
                provider: "openai",
                model: "gpt-3.5-turbo",       // Cheaper for staging
                timeout: 15,
                retries: 2,
                logLevel: "INFO"
            },
            "production": {
                provider: "openai",
                model: "gpt-4o",              // Best quality for prod
                fallbackProvider: "claude",
                timeout: 10,
                retries: 3,
                logLevel: "WARN",
                enableCaching: true,
                enableMonitoring: true
            }
        }

        return configs[ env ]
    }
}

Secrets Management

Never hardcode API keys:

// ❌ WRONG
apiKey = "sk-1234567890abcdef"

// ✅ RIGHT - Environment variables
apiKey = getSystemSetting( "OPENAI_API_KEY" )

// ✅ RIGHT - AWS Secrets Manager
function getAPIKey( secretName ) {
    return awsSecretsManager.getSecret( secretName ).getValue()
}

// ✅ RIGHT - Azure Key Vault
function getAPIKey( secretName ) {
    return azureKeyVault.getSecret( secretName )
}

// ✅ RIGHT - HashiCorp Vault
function getAPIKey( path ) {
    return vaultClient.read( path ).data.apiKey
}

Dynamic Configuration Reloading

// Reload config without restarting app
class singleton {
    property name="config" type="struct";
    property name="lastReload" type="date";

    function init() {
        reloadConfig()
        return this
    }

    function reloadConfig() {
        variables.config = deserializeJSON(
            fileRead( "/config/ai-production.json" )
        )
        variables.lastReload = now()
        writeLog( "AI configuration reloaded" )
    }

    function getConfig() {
        // Auto-reload every 5 minutes
        if ( dateDiff( "n", variables.lastReload, now() ) > 5 ) {
            reloadConfig()
        }
        return variables.config
    }
}

🛡️ Error Handling & Resilience

Comprehensive Error Handling

class {
    function safeAIChat( required string prompt, struct params = {}, struct options = {} ) {
        var maxRetries = params.maxRetries ?: 3
        var retryDelay = params.retryDelay ?: 1000  // milliseconds

        for ( var attempt = 1; attempt <= maxRetries; attempt++ ) {
            try {
                return aiChat(
                    arguments.prompt,
                    arguments.params,
                    arguments.options
                )

            } catch ( RateLimitException e ) {
                writeLog(
                    "Rate limit hit (attempt #attempt#/#maxRetries#): #e.message#",
                    "warning"
                )

                if ( attempt < maxRetries ) {
                    // Exponential backoff
                    sleep( retryDelay * attempt )
                } else {
                    // Try fallback provider
                    return tryFallbackProvider( arguments.prompt, arguments.params )
                }

            } catch ( TimeoutException e ) {
                writeLog(
                    "Timeout (attempt #attempt#/#maxRetries#): #e.message#",
                    "error"
                )

                if ( attempt == maxRetries ) {
                    return getDefaultResponse( arguments.prompt )
                }

            } catch ( AuthenticationException e ) {
                writeLog( "Authentication failed: #e.message#", "critical" )
                notifyOps( "AI authentication failure", e )
                throw e  // Don't retry auth errors

            } catch ( any e ) {
                writeLog(
                    "AI error (attempt #attempt#/#maxRetries#): #e.message#",
                    "error"
                )

                if ( attempt == maxRetries ) {
                    notifyOps( "AI service failure", e )
                    return getDefaultResponse( arguments.prompt )
                }
            }
        }
    }

    function tryFallbackProvider( required string prompt, struct params = {} ) {
        writeLog( "Attempting fallback provider", "info" )

        var fallbackProviders = [ "claude", "gemini", "groq" ]

        for ( var provider in fallbackProviders ) {
            try {
                return aiChat(
                    arguments.prompt,
                    arguments.params,
                    { provider: provider }
                )
            } catch ( any e ) {
                writeLog( "Fallback provider #provider# failed: #e.message#", "warning" )
            }
        }

        throw "All AI providers failed"
    }

    function getDefaultResponse( required string prompt ) {
        // Return safe fallback response
        return "I apologize, but I'm experiencing technical difficulties. " &
               "Please try again in a moment or contact support if the issue persists."
    }

    function notifyOps( required string message, any error ) {
        // Send to monitoring system
        // Slack, PagerDuty, email, etc.
    }
}

Circuit Breaker Pattern

Prevent cascading failures:

class singleton {
    property name="failures" type="numeric" default="0";
    property name="lastFailure" type="date";
    property name="state" type="string" default="CLOSED";  // CLOSED, OPEN, HALF_OPEN
    property name="threshold" type="numeric" default="5";
    property name="timeout" type="numeric" default="60";  // seconds

    function call( required function operation ) {
        if ( variables.state == "OPEN" ) {
            if ( dateDiff( "s", variables.lastFailure, now() ) > variables.timeout ) {
                variables.state = "HALF_OPEN"
                writeLog( "Circuit breaker entering HALF_OPEN state" )
            } else {
                throw "Circuit breaker is OPEN - service unavailable"
            }
        }

        try {
            var result = arguments.operation()

            if ( variables.state == "HALF_OPEN" ) {
                reset()
            }

            return result

        } catch ( any e ) {
            recordFailure()
            throw e
        }
    }

    function recordFailure() {
        variables.failures++
        variables.lastFailure = now()

        if ( variables.failures >= variables.threshold ) {
            variables.state = "OPEN"
            writeLog( "Circuit breaker OPENED after #variables.failures# failures", "critical" )
            notifyOps( "AI circuit breaker opened" )
        }
    }

    function reset() {
        variables.failures = 0
        variables.state = "CLOSED"
        writeLog( "Circuit breaker CLOSED - service recovered" )
    }

    function getState() {
        return variables.state
    }
}

// Usage
circuitBreaker = getInstance( "CircuitBreaker" )

response = circuitBreaker.call( () => {
    return aiChat( "What is BoxLang?" )
} )

📊 Monitoring & Observability

Event-Based Monitoring

Use BoxLang AI's event system:

// EventListener.bx
class {
    function onAIRequest( event, interceptData ) {
        var startTime = getTickCount()
        interceptData.startTime = startTime

        writeLog(
            "AI Request: provider=#interceptData.provider#, model=#interceptData.chatRequest.model#",
            "info"
        )
    }

    function onAIResponse( event, interceptData ) {
        var duration = getTickCount() - interceptData.startTime
        var tokenCount = interceptData.response.usage?.total_tokens ?: 0

        // Log metrics
        writeLog(
            "AI Response: duration=#duration#ms, tokens=#tokenCount#, provider=#interceptData.provider#",
            "info"
        )

        // Send to monitoring
        sendMetric( "ai.request.duration", duration, {
            provider: interceptData.provider,
            model: interceptData.chatRequest.model
        } )

        sendMetric( "ai.tokens.used", tokenCount, {
            provider: interceptData.provider
        } )

        // Track costs
        var cost = estimateCost( interceptData.provider, tokenCount )
        sendMetric( "ai.cost", cost, {
            provider: interceptData.provider
        } )
    }

    function onAIError( event, interceptData ) {
        writeLog(
            "AI Error: #interceptData.error.message#, provider=#interceptData.provider#",
            "error"
        )

        sendMetric( "ai.errors", 1, {
            provider: interceptData.provider,
            errorType: interceptData.error.type
        } )

        // Alert on high error rate
        if ( getErrorRate() > 0.05 ) {  // 5% error threshold
            notifyOps( "High AI error rate detected" )
        }
    }
}

// Register listeners in ModuleConfig.bx or Application.bx
BoxRegisterInterceptor(
    interceptorObject: new EventListener(),
    interceptorName: "AIMonitoring"
)

Metrics Collection

class singleton {
    property name="metrics" type="struct";

    function init() {
        variables.metrics = {
            requests: 0,
            successes: 0,
            failures: 0,
            totalTokens: 0,
            totalCost: 0,
            byProvider: {}
        }
        return this
    }

    function recordRequest(
        required string provider,
        required numeric tokens,
        required numeric cost,
        boolean success = true
    ) {
        lock name="metrics" type="exclusive" timeout="5" {
            variables.metrics.requests++

            if ( arguments.success ) {
                variables.metrics.successes++
            } else {
                variables.metrics.failures++
            }

            variables.metrics.totalTokens += arguments.tokens
            variables.metrics.totalCost += arguments.cost

            if ( !structKeyExists( variables.metrics.byProvider, arguments.provider ) ) {
                variables.metrics.byProvider[ arguments.provider ] = {
                    requests: 0,
                    tokens: 0,
                    cost: 0
                }
            }

            variables.metrics.byProvider[ arguments.provider ].requests++
            variables.metrics.byProvider[ arguments.provider ].tokens += arguments.tokens
            variables.metrics.byProvider[ arguments.provider ].cost += arguments.cost
        }
    }

    function getMetrics() {
        lock name="metrics" type="readonly" timeout="5" {
            return duplicate( variables.metrics )
        }
    }

    function reset() {
        init()
    }
}

// Expose metrics endpoint
// /api/metrics
function metrics() {
    var metricsService = getInstance( "MetricsService" )
    return renderJSON( metricsService.getMetrics() )
}

Health Checks

// /health endpoint
function health() {
    var status = {
        status: "healthy",
        timestamp: now(),
        checks: {}
    }

    // Check AI providers
    providers = [ "openai", "claude" ]
    for ( provider in providers ) {
        try {
            var start = getTickCount()
            aiChat( "test", { max_tokens: 1 }, { provider: provider } )
            status.checks[ provider ] = {
                status: "up",
                responseTime: getTickCount() - start
            }
        } catch ( any e ) {
            status.status = "degraded"
            status.checks[ provider ] = {
                status: "down",
                error: e.message
            }
        }
    }

    // Check memory systems
    try {
        var memory = aiMemory( "cache" )
        memory.add( { role: "user", content: "test" } )
        memory.clear()
        status.checks.memory = { status: "up" }
    } catch ( any e ) {
        status.status = "degraded"
        status.checks.memory = {
            status: "down",
            error: e.message
        }
    }

    // Set HTTP status code
    if ( status.status == "healthy" ) {
        setHTTPStatus( 200 )
    } else {
        setHTTPStatus( 503 )
    }

    return renderJSON( status )
}

Logging Best Practices

// Structured logging
function logAIInteraction(
    required string action,
    required string provider,
    struct metadata = {}
) {
    var logData = {
        timestamp: now(),
        action: arguments.action,
        provider: arguments.provider,
        userId: session.userId ?: "anonymous",
        requestId: request.requestId ?: createUUID(),
        metadata: arguments.metadata
    }

    writeLog(
        text: serializeJSON( logData ),
        type: "information",
        file: "ai-interactions"
    )
}

// Usage
logAIInteraction(
    action: "chat_request",
    provider: "openai",
    metadata: {
        model: "gpt-4",
        promptLength: len( prompt ),
        temperature: 0.7
    }
)

⚡ Performance Optimization

Response Caching

class {
    function getCachedAIResponse(
        required string prompt,
        struct params = {},
        numeric ttl = 3600
    ) {
        // Generate cache key
        var cacheKey = hash(
            serializeJSON({
                prompt: arguments.prompt,
                params: arguments.params
            }),
            "MD5"
        )

        // Try cache first
        var cached = cacheGet( "ai_#cacheKey#" )
        if ( !isNull( cached ) ) {
            writeLog( "AI cache hit for: #left( arguments.prompt, 50 )#..." )
            return cached
        }

        // Call AI
        var response = aiChat( arguments.prompt, arguments.params )

        // Cache response
        cacheSet(
            "ai_#cacheKey#",
            response,
            arguments.ttl
        )

        return response
    }
}

Connection Pooling

// For JDBC memory
datasource = {
    name: "aiMemory",
    driver: "postgresql",
    url: "jdbc:postgresql://localhost:5432/ai_db",
    username: getSystemSetting( "DB_USER" ),
    password: getSystemSetting( "DB_PASSWORD" ),

    // Connection pool settings
    maxConnections: 50,
    minConnections: 10,
    maxIdleTime: 30,
    connectionTimeout: 5000,
    validationQuery: "SELECT 1"
}

Async Processing

// Non-blocking AI calls
function processUserRequest( required string prompt ) {
    // Return immediately with request ID
    var requestId = createUUID()

    // Process in background
    runAsync( () => {
        try {
            var response = aiChat( arguments.prompt )

            // Store result
            cacheSet( "ai_result_#requestId#", {
                status: "completed",
                response: response
            }, 300 )

            // Notify user (websocket, email, etc.)
            notifyUser( session.userId, requestId, response )

        } catch ( any e ) {
            cacheSet( "ai_result_#requestId#", {
                status: "failed",
                error: e.message
            }, 300 )
        }
    } )

    return {
        requestId: requestId,
        status: "processing"
    }
}

// Check result endpoint
function checkResult( required string requestId ) {
    var result = cacheGet( "ai_result_#arguments.requestId#" )

    if ( isNull( result ) ) {
        return { status: "processing" }
    }

    return result
}

Batch Processing

// Process multiple prompts efficiently
function batchAIChat( required array prompts ) {
    var futures = []

    // Start all requests in parallel
    for ( var prompt in arguments.prompts ) {
        futures.append(
            aiChatAsync( prompt )
        )
    }

    // Collect results
    var results = []
    for ( var future in futures ) {
        try {
            results.append({
                success: true,
                response: future.get( 30, "seconds" )
            })
        } catch ( any e ) {
            results.append({
                success: false,
                error: e.message
            })
        }
    }

    return results
}
