AWS Integration Guide¶

This guide explains how to deploy and integrate TelcoAPI with Amazon Web Services (AWS).

Architecture Overview¶

TelcoAPI can be deployed on AWS using the following services: - Amazon ECS/EKS for containerized deployment - Amazon RDS for database - Amazon ElastiCache for caching - Amazon API Gateway for API management - AWS Lambda for serverless functions

Deployment Options¶

Container-based Deployment (ECS/EKS)¶

# docker-compose.yml for local testing
version: '3.8'
services:
  telco-api:
    image: telco-api:latest
    environment:
      - AWS_REGION=us-east-1
      - AWS_ACCESS_KEY_ID=
      - AWS_SECRET_ACCESS_KEY=
    ports:
      - "3000:3000"

// AWS SDK configuration
import { AWS } from '@aws-sdk/client-sdk';

AWS.config.update({
  region: process.env.AWS_REGION,
  credentials: {
    accessKeyId: process.env.AWS_ACCESS_KEY_ID,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
  }
});

Serverless Deployment (Lambda)¶

// Lambda handler
export const handler = async (event: APIGatewayEvent): Promise<APIGatewayProxyResult> => {
  try {
    const telcoApi = new TelcoAPI({
      region: process.env.AWS_REGION,
      // Additional configuration
    });

    const result = await telcoApi.handleRequest(event);

    return {
      statusCode: 200,
      body: JSON.stringify(result)
    };
  } catch (error) {
    return {
      statusCode: 500,
      body: JSON.stringify({ error: error.message })
    };
  }
};

Infrastructure as Code¶

CloudFormation Template¶

AWSTemplateFormatVersion: '2010-09-09'
Resources:
  TelcoApiCluster:
    Type: AWS::ECS::Cluster
    Properties:
      ClusterName: telco-api-cluster

  TelcoApiTaskDefinition:
    Type: AWS::ECS::TaskDefinition
    Properties:
      Family: telco-api
      ContainerDefinitions:
        - Name: telco-api
          Image: !Sub ${AWS::AccountId}.dkr.ecr.${AWS::Region}.amazonaws.com/telco-api:latest
          Memory: 512
          PortMappings:
            - ContainerPort: 3000
              Protocol: tcp

  TelcoApiService:
    Type: AWS::ECS::Service
    Properties:
      Cluster: !Ref TelcoApiCluster
      TaskDefinition: !Ref TelcoApiTaskDefinition
      DesiredCount: 2

Security Configuration¶

IAM Roles and Policies¶

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "dynamodb:PutItem",
        "dynamodb:GetItem",
        "dynamodb:UpdateItem",
        "dynamodb:DeleteItem",
        "dynamodb:Query",
        "dynamodb:Scan"
      ],
      "Resource": "arn:aws:dynamodb:*:*:table/TelcoAPI*"
    }
  ]
}

VPC Configuration¶

const vpcConfig = {
  vpcId: 'vpc-xxxxxxxx',
  subnets: ['subnet-xxxxxxxx', 'subnet-yyyyyyyy'],
  securityGroups: ['sg-xxxxxxxx']
};

Monitoring and Logging¶

CloudWatch Integration¶

import { CloudWatch } from '@aws-sdk/client-cloudwatch';

const cloudwatch = new CloudWatch({
  region: process.env.AWS_REGION
});

// Send custom metric
await cloudwatch.putMetricData({
  Namespace: 'TelcoAPI',
  MetricData: [{
    MetricName: 'RequestLatency',
    Value: 100,
    Unit: 'Milliseconds',
    Dimensions: [{
      Name: 'ApiEndpoint',
      Value: '/v1/diameter/gx'
    }]
  }]
});

X-Ray Tracing¶

import { AWSXRay } from 'aws-xray-sdk';

// Enable X-Ray tracing
AWSXRay.captureHTTPsGlobal(require('http'));
AWSXRay.capturePromise();

// Trace a segment
AWSXRay.captureAsyncFunc('processRequest', async (subsegment) => {
  try {
    // Your code here
    subsegment.close();
  } catch (error) {
    subsegment.close(error);
  }
});

Scaling and High Availability¶

Auto Scaling Configuration¶

const autoScalingConfig = {
  minCapacity: 2,
  maxCapacity: 10,
  targetCpuUtilization: 70,
  targetMemoryUtilization: 80
};

Multi-Region Deployment¶

const regions = ['us-east-1', 'eu-west-1', 'ap-southeast-1'];

for (const region of regions) {
  const api = new TelcoAPI({
    region,
    highAvailability: true,
    failover: {
      enabled: true,
      priority: regions.indexOf(region)
    }
  });
}

Cost Optimization¶

Use Spot Instances for non-critical workloads
Implement Auto Scaling based on demand
Use AWS Savings Plans for predictable workloads
Monitor and optimize resource utilization

Best Practices¶

Security
Use AWS Secrets Manager for sensitive data
Implement least privilege access
Enable AWS WAF for API Gateway
Performance
Use ElastiCache for caching
Implement request throttling
Use CloudFront for content delivery
Reliability
Deploy across multiple AZs
Implement circuit breakers
Use health checks and auto-healing

Troubleshooting¶

Common Issues¶

Connection Timeouts
Check security group rules
Verify VPC configuration
Check network ACLs
Permission Errors
Verify IAM roles and policies
Check resource-based policies
Review service limits

Debugging Tools¶

// Enable debug logging
const debug = require('debug')('telco-api:aws');

debug('Initializing AWS services');
debug('Configuration:', JSON.stringify(config, null, 2));
