Building a Spring Boot application is only half the journey. At some point, every backend project reaches the next question: Where should this application actually run? If you are deploying on AWS, two common options are: Amazon EC2 Amazon ECS Both can run the same Dockerized Spring Boot application. But they are not the same kind of deployment model. EC2 gives you a server. ECS gives you container orchestration. Choosing between them is less about which one is “better” and more about which one fits the stage of your application. Starting with EC2 EC2 is the most direct way to run a Spring Boot application on AWS. You create a virtual machine, install what you need, and run your application. For a Dockerized Spring Boot app, the flow often looks like this: GitHub Actions ↓ SSH into EC2 ↓ Pull latest code or image ↓ Build / run Docker container ↓ Spring Boot app runs on EC2 The mental model is simple: One server One Docker container One Spring Boot application That simplicity is useful. Especially when you are launching an MVP, a freelancer project, an internal tool, or your first production version. Why EC2 Works Well for Many Spring Boot Apps EC2 is not outdated just because newer deployment platforms exist. For many applications, EC2 is enough. It works well when: traffic is predictable the application is small or medium-sized you want full control over the server you want simple debugging through SSH you do not need multiple replicas yet you want to keep infrastructure easy to understand A common setup might be: Spring Boot Dockerfile Docker Compose GitHub Actions EC2 That setup can be production-ready for many early-stage apps. It gives you: a real deployment target repeatable Docker builds automated deployment through GitHub Actions simple logs direct server access For a solo developer or small team, that matters. You can understand the entire deployment flow without needing a full container orchestration platform. The Tradeoff With EC2 The tradeoff is that you

Introduction In my previous IAM article we learnt basics of IAM and how to create Users, Groups and attach Policies. You can refer here: https://dev.to/kadhamvj23/aws-identity-and-access-management-explained-for-beginners-cn7 After setting up secure access to our AWS account using IAM, the next question we mostly have is where do we actually run our application? The answer is Amazon EC2 - Elastic Cloud Compute. EC2 is one of the most widely used AWS services and understanding it well is essential for anyone starting their cloud journey. In this article we will cover what EC2 is, why it exists, the different types of instances, pricing models, Regions and availability Zones and finally hands-on walk through of creating your first EC2 instance. Breaking Down the Name -EC2 Let us understand what each word in the name actually means: Elastic --> In AWS you will notice many services have this prefix "Elastic". The reason is simple. Whenever AWS provides a service that can be scaled up or scaled down based on our needs, that service is called Elastic . With EC2 you can increase resources when traffic is high and decrease them when the traffic is low. So in simple terms EC2 = A virtual server on the cloud that you can resize anytime. Cloud: EC2 runs on AWS's public cloud infrastructure, meaning the servers are owned and managed by Amazon across the world. Compute: The word compute means you are asking AWS to provide you CPU, RAM and Disk - basically a virtual machine or server that can run your applications. How does EC2 actually work? When you request a Virtual server from AWS, here is what happens behind the scenes: You request a virtual machine on AWS ⬇️ request goes to a Hypervisor(a software layer sitting on top of physical servers that creates and manages VMs) ⬇️ Hypervisor creates your VM ⬇️ You get the access to your EC2 instance You never touch any physical hardware. AWS manages all of that for you. Why use EC2? Imagine your company wants to host an application. T
