Once again, be sure you understand how the free-tier models work to avoid any charges. You will need to use the EC2 and S3 server models you previously used to assist in the project. Essentially, you will spin those servers up and configure the software for supporting the database and web application.

The Web application should be simple. It should consist of at least two Web pages with data being transferred between a Web browser and the cloud application and make use of the database for storage, updates or reads as needed. As an example you could create a simple login form that allows a user to login and then update their user information. You are welcome to make the Web application more complex. The AWS can be relational or no SQL-based.

It should be simple with no more than a 3-4 tables. For your documentation, you should describe the steps used to successfully complete this assignment, provide screen capture documentation of those steps and discuss any challenges you faced and how you overcame those challenges. You should also show screen captures and a complete description of your application and you successfully executing it. Document the server instance names you created and the time spent for each instance. You should be able to monitor the number hours and minutes spent on each server.

Finally, and most importantly, be sure to shut down each instance to avoid any additional charges to your account. Your document should be well-organized, well-written and provide all references used for your research. There should be minimal spelling and grammatical errors.

Creating a Simple Web Database Application Using AWS Free Tier

The objective of this project is to leverage Amazon Web Services (AWS) free-tier offerings to develop a basic web database application. This process involves deploying and configuring AWS EC2 (Elastic Compute Cloud) and S3 (Simple Storage Service) instances to support a web interface that interacts with a database. The goal is to understand cloud infrastructure management, database integration, and cost control, while producing a functional, minimal web application with thorough documentation.

Introduction

Cloud computing has revolutionized how developers build, deploy, and manage applications by providing scalable and cost-effective infrastructure. AWS, as a leading cloud provider, offers a free-tier model that grants access to certain resources with no cost, provided usage remains within specified limits. This project utilizes AWS's free-tier EC2 and S3 services to create a simple, yet functional, web-based database application that serves as a practical exercise in cloud deployment, configuration, and management.

Design and Functionality of the Web Application

The designed web application consists of at least two web pages: a login page and a user profile page, interconnected through data interactions with a database. The application enables user authentication and profile management, including viewing and updating user details. Its structure employs a relational database with 3-4 tables, such as Users, UserDetails, LoginHistory, and Preferences, balancing simplicity with functional relevance.

Implementation Steps

1. Setting up AWS EC2 Instance

The first step involved launching an EC2 instance using the free-tier Amazon Linux AMI. During setup, instance details such as name (e.g., "WebApp_EC2") and configuration parameters were documented. The instance was configured with security groups to allow HTTP (port 80), HTTPS (port 443), and SSH (port 22) access. Once the instance was launched, SSH access was established for further configuration.

Using SSH, necessary software was installed: Apache web server, PHP or Node.js, and a database server such as MySQL or a NoSQL alternative like MongoDB, based on project preference. The setup ensured that the server was capable of serving web pages and interacting with the database.

2. Setting up the Database

A relational database was configured on the EC2 instance, creating the essential tables—Users, UserDetails, LoginHistory, and Preferences. SQL scripts were written and executed to create these tables. Each table's schema was documented, specifying primary keys, foreign keys, and data types to ensure data integrity and efficient querying.

Additionally, security best practices were applied: database access was restricted locally, and user credentials were secured. The database was tested with sample data entries to confirm correct operation.

3. Configuring the Web Application

The web application code was developed locally, implementing two key pages: a login page and a profile update page. The frontend utilized HTML/CSS and JavaScript, while server-side scripts (PHP or Node.js) handled requests, communicated with the database, and dynamically rendered pages. These scripts were then transferred to the EC2 instance via SCP or FTP, and the web server was configured to serve these pages.

The login process involved verifying user credentials against the database, while the profile page allowed data retrieval and updates. Proper form validation and security measures, such as input sanitization, were implemented to prevent vulnerabilities.

4. Using AWS S3 for Static Files

Static assets such as images, CSS, and JavaScript files were uploaded to an S3 bucket configured for static website hosting. The web pages referenced these assets via the S3 URL, improving scalability and isolating static content from dynamic application logic.

5. Monitoring and Cost Management

Throughout the project, the AWS Cost Explorer and billing dashboard were monitored to ensure usage stayed within free-tier limits. Instance uptime and hours were logged, with notes on the total time spent on each server instance, demonstrating effective resource management.

6. Shutting Down Instances

After completion, all EC2 instances were properly stopped to prevent any additional charges. The process involved terminating server instances via the AWS Management Console and confirming their shutdown status. Documentation of timestamps and duration on each server was maintained for thorough reporting.

Challenges and Solutions

Several challenges emerged during this process, including configuring the firewall rules to allow necessary ports, securing database credentials, and ensuring the web server correctly interfaced with the database. Troubleshooting involved reviewing AWS security groups, adjusting access permissions, and inspecting error logs to diagnose and resolve connectivity issues. Using detailed documentation, online resources, and AWS forums proved invaluable during problem resolution.

Another significant challenge was managing costs, ensuring server instances were not left running unintentionally. Regular monitoring and timely shutdowns addressed this concern effectively.

Application Description and Execution

The final application comprises a user-friendly interface for login and profile management. Upon successful login, users can view and update their profile information, which updates the corresponding database entries. Screenshots of the application interface, server configuration, and test runs demonstrate correct functionality. The system’s responsiveness and data integrity validate the successful deployment of the web database application.

Conclusion

This project showcases how leveraging AWS free-tier resources enables the deployment of a functional web database application with minimal costs. The hands-on experience with EC2, S3, database systems, and web development fosters essential cloud computing skills. Proper planning, monitoring, and shutdown procedures are critical to maintaining the project’s cost effectiveness. Future improvements could include enhanced security measures, scalability features, and integration with additional AWS services such as Lambda or API Gateway.
