Introduction<\/h3>\n\n\n\n

Serverless architectures minimize operational overhead and can be very cost-effective for variable workloads. This post covers how to build and optimize Lambda + API Gateway apps for cost.<\/p>\n\n\n\n

Implementation Steps<\/h3>\n\n\n\n
    \n
  1. Create Lambda Functions<\/strong>\n
      \n
    • Write stateless functions triggered by HTTP API Gateway events.<\/li>\n\n\n\n
    • Package and deploy using SAM, Serverless Framework, or CDK.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Set up API Gateway<\/strong>\n
        \n
      • Use REST or HTTP APIs depending on needs (HTTP APIs are cheaper).<\/li>\n\n\n\n
      • Enable caching for frequently requested data.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Select Database<\/strong>\n
          \n
        • Use DynamoDB or Aurora Serverless for backend persistence.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Configure IAM Roles and Policies<\/strong>\n
            \n
          • Limit permissions to least privilege.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • Set Up Monitoring and Alerts<\/strong>\n
              \n
            • Use CloudWatch Logs and metrics for Lambda invocations and errors.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

              Cost Optimization Tips<\/h3>\n\n\n\n
                \n
              • Use HTTP APIs over REST APIs:<\/strong> HTTP APIs cost less per million requests.<\/li>\n\n\n\n
              • Keep Lambda Function Execution Times Low:<\/strong> Optimize code to reduce run time and memory usage.<\/li>\n\n\n\n
              • Use Provisioned Concurrency Only When Needed:<\/strong> On-demand is cheaper for spiky workloads.<\/li>\n\n\n\n
              • Set Up API Gateway Caching:<\/strong> Cache common responses to reduce Lambda invocations.<\/li>\n\n\n\n
              • Use DynamoDB On-Demand Mode:<\/strong> Pay per request for unpredictable workloads.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
