Serverless Architecture

Why Serverless?

Serverless computing transforms how we build and operate applications. We help teams adopt serverless to ship faster and operate more efficiently:

• No server management - Focus on writing code, not maintaining infrastructure
• Automatic scaling - Handle 10 requests or 10 million without configuration
• Pay-per-request - No paying for idle servers, only actual usage
• Faster time to market - Deploy features in minutes, not days
• Built-in reliability - Leverage AWS managed services with 99.9%+ uptime

Our Serverless Services

Architecture Design

Design event-driven systems that scale automatically:

• Event-driven patterns: Async workflows with EventBridge, SQS, and SNS
• Microservices decomposition: Break monoliths into independent functions
• API design: RESTful and GraphQL APIs with API Gateway
• Data architecture: DynamoDB, Aurora Serverless, S3 for serverless data storage

Implementation

Build production-ready serverless applications:

• AWS Lambda: Node.js, Python, Go functions with proper error handling
• API Gateway: HTTP and WebSocket APIs with authentication
• Step Functions: Complex workflows and state machines
• EventBridge: Event routing and integration patterns
• CloudWatch: Logging, monitoring, and alerting

Here's an example serverless pattern for processing events:

// Event-driven order processing with Lambda and EventBridge
import { EventBridgeHandler } from 'aws-lambda';
import { SQSClient, SendMessageCommand } from '@aws-sdk/client-sqs';

interface OrderCreatedEvent {
  orderId: string;
  customerId: string;
  items: Array<{ sku: string; quantity: number }>;
  total: number;
}

export const handler: EventBridgeHandler<'OrderCreated', OrderCreatedEvent, void> = async (event) => {
  const order = event.detail;

  // Send to fulfillment queue
  await sqsClient.send(new SendMessageCommand({
    QueueUrl: process.env.FULFILLMENT_QUEUE_URL,
    MessageBody: JSON.stringify({
      orderId: order.orderId,
      items: order.items,
    }),
  }));

  // Trigger email notification
  await eventBridgeClient.putEvents({
    Entries: [{
      Source: 'orders',
      DetailType: 'OrderConfirmation',
      Detail: JSON.stringify({
        customerId: order.customerId,
        orderId: order.orderId,
        total: order.total,
      }),
    }],
  });
};

Migration

Move from traditional servers to serverless:

• Lift and shift: Containerize existing apps with Fargate or App Runner
• Incremental migration: Replace components one at a time
• Strangler fig pattern: Route traffic between old and new systems
• Data migration: Move databases to managed serverless options

Optimization

Improve performance and reduce costs:

• Cold start optimization: Bundle size reduction, provisioned concurrency
• Cost analysis: Right-size memory, eliminate waste, use reserved capacity
• Performance tuning: Async patterns, connection pooling, caching strategies
• Observability: Distributed tracing with X-Ray, structured logging, custom metrics

When to Go Serverless

Serverless is ideal for:

• Event-driven workloads - Processing webhooks, file uploads, scheduled tasks
• Variable traffic - Traffic that spikes unpredictably or has long quiet periods
• Rapid development - MVPs and prototypes that need fast iteration
• Cost-conscious applications - Development environments, low-traffic APIs
• Integration workloads - Glue code between SaaS tools and APIs

When serverless might not fit:

• Long-running processes - Tasks that run for hours continuously (use containers instead)
• Consistent high throughput - If you're always at peak, dedicated servers may be cheaper
• Specialized hardware needs - GPU computing, specific compliance requirements
• Team unfamiliarity - If the learning curve outweighs benefits for your timeline

We'll help you honestly assess whether serverless is right for your use case.
