Deploying a Go application on AWS in 2025 has become more streamlined and efficient, leveraging advanced AWS services to ensure optimal performance and scalability. This guide will walk you through the essential steps to get your Go application up and running on AWS, taking advantage of modern tooling and best practices.

Prerequisites

Before you begin, ensure you have the following:

  1. AWS Account: Set up an AWS account if you haven’t already.
  2. Go Installed: Make sure your local environment has the latest Go version installed. You can verify this by running go version in your terminal.
  3. Docker: Install Docker to containerize your Go application.

Step-by-Step Deployment

1. Containerize Your Go Application

The first step in deploying your Go application is to containerize it using Docker. Create a Dockerfile in the root of your application directory:

# Use the official Golang image
FROM golang:latest

# Set the Current Working Directory inside the container
WORKDIR /app

# Copy the source code into the container
COPY . .

# Build the Go application
RUN go build -o myapp

# Command to run the executable
CMD ["./myapp"]

2. Push Docker Image to Amazon ECR

Amazon Elastic Container Registry (ECR) is the ideal place to store your Docker images:

  • Create an ECR Repository: Use the AWS CLI to create a repository.
  • Authenticate Docker with ECR: Run aws ecr get-login-password and pipe it to Docker to authenticate.
  • Push Image: Tag and push your Docker image to ECR.

3. Deploy Using Amazon ECS or AWS Lambda

Option 1: Amazon ECS

Amazon ECS (Elastic Container Service) is a powerful tool for running containerized applications:

  • Create a Cluster: Set up a new ECS cluster.
  • Define a Task: Register your Docker container as a task definition.
  • Service Creation: Deploy the task as a service within your ECS cluster.

Option 2: AWS Lambda

For serverless deployment, consider AWS Lambda with Amazon API Gateway:

  • Zip and Upload: Package your Go binary, upload it to S3, and create a Lambda function pointing to it.
  • Configure a Trigger: Use API Gateway to expose your Lambda function.

4. Monitor and Scale

Utilize AWS CloudWatch for monitoring and enable auto-scaling to handle traffic spikes, ensuring your application runs smoothly.
