How to Deploy an App to AWS

Deploying an app to AWS (Amazon Web Services) can seem daunting, but it’s straightforward once you understand the key components. AWS offers many services to host and manage applications, ranging from virtual machines to fully managed serverless platforms.

Basic steps to deploy a simple web app:

  1. Create an AWS account: Sign up at aws.amazon.com and set up IAM users with proper permissions.
  2. Choose your deployment method:
    • EC2: Launch a virtual machine, install your stack manually.
    • Elastic Beanstalk: A Platform-as-a-Service (PaaS) for quick deployments.
    • S3 + CloudFront: For static websites (HTML/CSS/JS).
    • Lambda + API Gateway: For serverless applications.
  3. Prepare your app: Ensure your code is production-ready. Package it appropriately—ZIP file, Docker container, or build artifact.
  4. Upload and configure:
    • For EC2: SSH into your instance, transfer files, and run your server.
    • For Beanstalk: Use the EB CLI or AWS Console to deploy and manage environments.
    • For Lambda: Upload functions via console or deploy using frameworks like Serverless.
  5. Configure networking: Use Elastic IPs, VPCs, and Security Groups to control access. Add a Load Balancer for redundancy.
  6. Set up DNS: Use Route 53 to connect your domain name to your app.
  7. Monitor and scale: Use CloudWatch for logs, alarms, and metrics. Set up Auto Scaling for high availability.

AWS provides powerful tools and granular control. With practice, you’ll be able to automate deployments using services like CodeDeploy, CloudFormation, or Terraform.

    Understanding Serverless Architecture

    Serverless architecture is a cloud computing execution model where the cloud provider manages the infrastructure, allowing developers to focus solely on writing code. Despite the name, “serverless” does not mean servers are eliminated—it means the server management is abstracted away from the developer. In a serverless model, your code is executed in response to events,…
