Serverless Architecture Implementation Reduced Costs by 40% for a FinTech Company Using AWS Lambda

Solutions

• An Amazon EC2 instance configured with Nginx directed requests to Amazon API Gateway, seamlessly routing them to the appropriate Lambda function.
• The architecture allowed Amazon API Gateway to efficiently route incoming requests to the right Lambda function.
• The Amazon HTTP API gateway was designed to handle up to 5,000 requests per second, dynamically throttling and scaling to 10,000 requests per second as needed.
• 26 AWS Lambda functions were used for data processing.
• AWS Lambda functions were positioned within a private subnet for secure internet access.
• Different AWS Lambda functions with distinct processing logic sent their outputs to an API.
• AWS Lambda functions could access Amazon RDS for data retrieval and storage.
• AWS CloudFormation Template was provided for the production server, enabling flexible configuration of instance types, AMI, and more. Amazon API Gateway, AWS Lambda Functions, and Amazon ECS were created through this CloudFormation Stack.
