AWS Create Lambda Function

To create a Lambda function on AWS, you can use the AWS Management Console, the AWS Command Line Interface (CLI), or the AWS SDKs. Here’s an overview of the process for creating a Lambda function using the AWS Management Console:

  1. Log in to the AWS Management Console and navigate to the Lambda service.
  2. Click on the “Create function” button to start the function creation process.
  3. Select “Author from scratch” and provide a name and runtime for your function.
  4. In the “Function code” section, you can choose to upload a .zip file containing your code and dependencies, or you can choose to write your code directly in the inline code editor.
  5. In the “Function configuration” section, you can set the amount of memory and timeout for your function, as well as configure any environment variables or VPC settings.
  6. In the “Permissions” section, you can specify the IAM role that will be assumed by the function when it is executed.
  7. Click on the “Create function” button to create your function.
  8. Once the function is created, you can test it by providing test events and invoking it.

You can also use CLI or SDKs for creating the function.

Once the function is created, you can configure triggers and events to invoke the function.

AWS Lambda Pricing

AWS Lambda pricing is based on the number of requests and the duration of each request. The cost of each request is determined by the amount of memory allocated to the function.

When a Lambda function is invoked, it is charged for the number of requests and the duration of the request in increments of 100ms.

There is no additional charge for the amount of data processed by the function, but data transferred in and out of the function is charged according to the Amazon S3 or Amazon DynamoDB pricing.

AWS also offers a free tier of 1 million free requests and 400,000 GB-seconds of compute time per month.

AWS also offers reserved instances that provide a lower cost than on-demand instances when the function is expected to run for a long period of time.

Overall AWS Lambda pricing is pay-per-use and allows customers to pay only for what they use and nothing more.
