Literally it deploys in <strong>under 3 mins</strong>!</p> <h2> What You'll Learn </h2> <ul> <li>How to write a minimal Spring Boot app for serverless</li> <li>How to define AWS infrastructure using Terraform (Lambda + API Gateway)</li> <li>How to deploy everything with a single script</li> <li>How to test endpoint on AWS</li> </ul> <h2> What's Inside the Demo </h2> <ul> <li>Java 17 + Spring Boot starter project</li> <li>Lambda-compatible handler</li> <li>Infrastructure-as-Code with Terraform</li> <li>API Gateway config</li> <li>Bash deploy script</li> <li>Lightweight README + setup guide</li> </ul> <p><strong>GitHub repo:</strong><br><br> <a href="https://github.com/ZPetrovich/springboot-aws-template-demo" rel="noopener noreferrer">https://github.com/ZPetrovich/springboot-aws-template-demo</a></p> <p><strong>1-minute walkthrough video:</strong><br><br> <a href="https://www.youtube.com/watch?v=agKj_un5PZg" rel="noopener noreferrer">https://www.youtube.com/watch?v=agKj_un5PZg</a></p> <h2> How to Try It Yourself </h2> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>git clone https://github.com/ZPetrovich/springboot-aws-template-demo <span class="nb">cd </span>springboot-aws-template-demo <span class="nb">chmod</span> +x deploy.sh ./deploy.sh </code></pre> </div> <p>You'll need:</p> <ul> <li>Java 17+</li> <li>AWS CLI + credentials</li> <li>Terraform 1.x+</li> </ul> <p>Once deployed, test the endpoint in your Browser:</p> <p><code>https://&lt;YOUR_AWS_GATEWAY_ID&gt;.execute-api.&lt;YOUR_AWS_REGION&gt;.amazonaws.com/prod/api/items/YOUR_KEYWORD</code></p> <p>The goal is to reduce the DevOps burden for solo developers, learners, and backend engineers who want to experiment with Lambda.</p> <p>If this project helps you, or if you see anything that could be improved — I’d love to hear from you.</p> <p>I'm happy to expand it further (add CI/CD, DynamoDB, multi-environment support, etc.) if there's interest.</p> <p>Thanks for reading!</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F2xwic1scj8w9hqam8j29.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F2xwic1scj8w9hqam8j29.png" alt="API Gateway" width="800" height="424"></a></p> java aws terraform springboot
