A FinTech Company achieves Cost-Effective AWS Infrastructure with Amazon API Gateway

Solutions

• An Amazon EC2 instance was configured with Nginx to handle request redirection to Amazon API Gateway, which in turn directed the requests to the appropriate AWS Lambda function. 
• This architecture allowed the Amazon API Gateway to seamlessly route incoming requests to the appropriate Lambda function. 
• The implementation of the Amazon HTTP API gateway was designed to handle a maximum of 5,000 requests per second, with the capability to dynamically throttle itself if necessary and scale up to 10,000 requests per second.  
• This flexible and adaptive configuration ensures that the API gateway can effectively manage varying levels of incoming traffic, maintaining optimal performance and preventing potential overload. 
• A single HTTP Amazon API Gateway was utilized to handle both GET and POST requests for 26 lambda functions. This streamlined approach consolidated the API calls, simplifying the architecture and improving overall efficiency. 
• The Amazon HTTP API gateway supported two types of API calls: public and private.  
• The public API calls were accessible to everyone, while the private API calls required IAM authentication, ensuring secure access for authorized individuals. This setup provided flexibility and enhanced security in managing different levels of API interactions. 
• AWS CloudFormation Template was provided for the production server, enabling the client to modify instance types for Amazon EC2 and Amazon RDS. Inputs such as AMI, instance type, RDS instance type, and key for the production setup could be specified through parameters. Amazon API Gateway, AWS Lambda Function, and Amazon ECS were created through AWS CloudFormation Stack.
