Golang Aws Lambda Tutorial

Golang (or Go) is a programming language developed by Google, and AWS Lambda is a serverless computing service provided by Amazon Web Services (AWS). You can use golang to write functions that can be executed by AWS Lambda.

To use golang with AWS Lambda, you will first need to create a golang function and compile it into a binary file. The function must have a specific format, with a specific input and output, in order to be compatible with AWS Lambda. Here is an example of a simple golang function that can be used with AWS Lambda:

package main

import (
    "context"
    "fmt"
)

// The main function is the entry point for the Lambda function.
func main() {
    // Create a new Lambda context
    ctx := context.Background()

    // Call the handler function
    if err := handler(ctx); err != nil {
        fmt.Println(err)
        return
    }
}

// The handler function is the main logic of the Lambda function.
func handler(ctx context.Context) error {
    // Print a message to the console
    fmt.Println("Hello, world!")
    return nil
}

Once you have created your golang function, you can compile it into a binary file using the go build command. Then, you can upload the binary file to AWS Lambda and create a new Lambda function.

You can also use the AWS SDK for golang to manage your AWS Lambda functions and access other AWS services from within your golang code. This can make it easier to integrate your golang functions with other AWS services, such as Amazon S3 and Amazon SNS.
