What We’ll Build

Throughout this course, we’ll deploy a complete Spring Boot application stack that includes:

  1. Application Layer: Spring Boot application configured for production
  2. Database Layer: MySQL database for persistent data storage
  3. Web Server Layer: Nginx as a reverse proxy for better performance and security
  4. Security Layer: SSL certificates for HTTPS encryption
  5. Domain Layer: Custom domain configuration for professional deployment

Prerequisites Overview

Before starting this course, you should have:

  • Java Development: Basic knowledge of Spring Boot framework
  • AWS Account: Active AWS account with billing configured
  • Command Line: Familiarity with terminal/command prompt
  • Web Concepts: Understanding of HTTP, domains, and basic networking
TipEstimated Time

This course typically takes 3-4 hours to complete, including hands-on practice and testing.

Course Structure

This course is organized into logical steps that build upon each other:

Prerequisites

We’ll start by ensuring you have everything needed for successful deployment.

Step-by-Step Deployment

The core of the course covers six essential steps:

  1. Configure Development and Production Profiles - Set up your Spring Boot application for different environments
  2. Create and Configure AWS Lightsail Instance - Launch and configure your cloud server
  3. Set Up MySQL Database - Configure persistent data storage
  4. Deploy Spring Boot Application - Get your application running on the server
  5. Configure Reverse Proxy - Set up Nginx for better performance and security
  6. Set Up Domain and SSL - Configure professional domain access with encryption

Troubleshooting

We’ll cover common issues and their solutions to help you resolve problems independently.

Real-World Application

The deployment strategy you’ll learn in this course is used by thousands of production applications. The skills you develop will be directly applicable to:

  • Personal Projects: Deploy your portfolio applications professionally
  • Client Work: Deliver production-ready applications to clients
  • Startup Applications: Cost-effective scaling for early-stage companies
  • Learning Environment: Create staging environments for testing

Cost Considerations

One of Lightsail’s major advantages is transparent, predictable pricing:

  • Basic Instance: $3.50/month (512 MB RAM, 1 vCPU)
