Abstract: This research paper delineates the creation and execution of an application based on serverless architecture, aimed at simplifying blood donation by enabling location-based donor searches. The system primarily uses cloud services such as API Gateway, Lambda Functions, and DynamoDB on popular cloud platforms. Google Maps API integration provides a dynamic mapping solution for a better user experience. This application allows a donor and blood bank to register their details including her GPS coordinates, thus providing users with an efficient and real-time way to find a donor nearby. Serverless architecture ensures cost efficiency, scalability, and seamless management of resources. API Gateway and Lambda functions are us ed to create RESTful APIs and facilitate communication between applications and databases. The DynamoDB database is used to store donor information, ensuring data persistence, reliability, and easy retrieval. Users can use the application to search for donors based on their current location and view the results on an interactive map. The system optimizes the blood donation process by calculating and displaying important information such as distance to the donor’s location, direction, and estimated time of arrival.
