Module 4: Web Application Deployment

You've put together a nice application - time to get it out there! A GitHub repo is great, but a deployed application is more effective in your portfolio as everyone in the hiring process (not just technical people) can check it out.

Note: While we use Heroku in this module as our primary deployment platform, it's important to know that Heroku has changed its pricing model and is no longer free by default. Alternatives like Render, Railway, or Fly.io offer similar functionality with generous free tiers for student projects. We'll include resources for these alternatives below.

1. Deploy a basic (single-server) web application to common cloud services

• Set up a cloud platform account (Heroku, AWS, etc.)
• Prepare a Flask application for deployment
• Configure environment variables for different deployment environments
• Manage dependencies for cloud deployment
• Deploy your application to a cloud service
• Monitor deployed application performance and logs

2. Securely connect a deployed web application to a relational database back-end

• Configure database connection strings for production environments
• Implement secure credential management
• Set up a production database instance
• Migrate local database schema to production
• Implement database connection pooling
• Manage database connections in a deployed environment
