In today's fast-paced financial markets, having timely and accurate information is crucial for making informed investment decisions. To streamline this process, I recently embarked on a project utilising AWS Lambda to automate fetching stock market data, generating prediction questions, and storing the results in a MySQL database. In this blog post, I will share my experience of developing and deploying this Python application and demonstrate how AWS Lambda, Docker, CloudWatch, and other AWS services played a vital role in its successful implementation.
Understanding the Project:
The primary objective of this project was to create a Python application that could predict the closing price of a specific stock by the end of the trading day. The application would generate a question related to the prediction and store the data in a MySQL database. To accomplish this, I leveraged the power of AWS Lambda, a serverless computing service that allows running code without provisioning or managing servers.
Building the Python Application:
To fetch the stock market data and generate prediction questions, I developed a Python application. I utilised various libraries and APIs to retrieve real-time market data and perform the necessary calculations. By combining data analysis techniques and machine learning algorithms, I could generate insightful questions related to the closing price of a specific stock.
Utilising AWS Lambda and Docker:
For deployment, I opted to use the AWS Lambda service. To simplify the process, I leveraged the AWS Lambda Docker image, which provides a ready-to-use environment for running Python code. This choice allowed me to package the application and its dependencies easily. By utilising Docker, I achieved consistency across different environments, making it simpler to reproduce the deployment process.
Scheduling with CloudWatch:
To execute the Lambda function automatically at a specific time each day, I employed AWS CloudWatch. CloudWatch provides powerful scheduling capabilities, allowing me to configure the Lambda function to run at 9:35 IST every day. This ensured that the predictions were generated and stored in the database at the desired time, providing valuable insights for the trading day.
Storing Data in MySQL Database:
To store the generated prediction questions and their corresponding answers, I integrated a MySQL database with the application. AWS Lambda supports seamless integration with various database services, including Amazon RDS. I set up a MySQL database instance on Amazon RDS and configured the application to connect to it securely. This allowed me to persist the prediction data for further analysis and retrieval.
In this project, I demonstrated how AWS Lambda, Docker, and other AWS services can be harnessed to automate stock market predictions. By utilising the power of serverless computing and leveraging the scalability and flexibility of AWS, I successfully developed and deployed a Python application that fetches stock market data, generates prediction questions, and stores the results in a MySQL database. This automation saves time and effort, providing valuable insights for traders and investors. With AWS Lambda, the possibilities for automating and streamlining various tasks are limitless.
As the stock market landscape continues to evolve rapidly, leveraging cloud-based solutions like AWS Lambda can help traders and investors stay competitive and make informed decisions. By combining technological innovation with financial expertise, this project showcases the potential for automation and intelligent data analysis in the financial domain.
