Creation of Lambda Service via Console

Recipe Objective - Creation of Lambda Service via Console?

The AWS Lambda is a widely used service and is defined as an event-driven, serverless computing platform provided by Amazon as part of Amazon Web Services. It is further defined as a computing service that runs code in response to events and automatically manages the computing resources required by that code. The AWS Lambda was introduced in November 2014. The AWS Lambda officially supports Node.js, Python, Java, Go, Ruby, and C# (through . NET) as of 2018. The AWS Lambda supports running native Linux executables via calling out from a supported runtime such as Node.js for example Haskell code which can be run on Lambda. The AWS Lambda was designed for use cases such as the image or object uploads to Amazon S3, updates to DynamoDB tables, responding to website clicks, or reacting to sensor readings from an IoT connected device. The AWS Lambda can also be used to automatically provision the back-end services triggered by custom HTTP requests, and "spin down" such services when not in use, to save resources and further these custom HTTP requests are to be configured in the AWS API Gateway, which can also handle authentication and authorization in conjunction with AWS Cognito. The AWS Lambda automatically responds to the code execution requests at any scale, from a dozen events per day to the hundreds of thousands per second.

Benefits of AWS Lambda

  • The AWS Lambda helps in executing code at the capacity you need as specified. It can be scaled to match the data volume automatically enabling custom event triggers and can process data at scale. The AWS Lambda can be combined with other AWS services to create secure, stable, and scalable online experiences to run interactive web and mobile backends. The AWS Lambda can preprocess the data before feeding it to the machine learning (ML) model and with Amazon Elastic File System (EFS) access, AWS Lambda handles the infrastructure management and provisioning to simplify scaling that is it enables powerful ML insights. The AWS Lambda builds event-driven functions for easy communication between the decoupled services and further reduce costs by running applications during times of peak demand without the crashing or over-provisioning resources that is it creates event-driven applications.

System Requirements

  • Any Operating System(Mac, Windows, Linux)

This recipe explains AWS Lambda and the creation of AWS Lambda via console.

Creation of AWS Lambda using console

    • Open the Functions page of the Lambda console and choose to Create function.

AWS Lambda offers services that open the functions page of the lambda console and further choose to create the function.

    • Under the Basic information, Enter my function for the Function name. Select the Node.js 14. x for Runtime.

AWS Lambda offers services where my-function can be added for the function name under the basic information. Also, the Node.js for the runtime.

    • Choose the Create function option.

AWS Lambda offers services that can be used to create function options.

    • Choose the Test tab after selecting the function created.

AWS Lambda offers a service that provides an option for choosing the Test tab after selecting the function created.

    • Choose New event in the Test event section Leave the default hello-world option in the Template and further Enter a Name for the test

The AWS Lambda provides an option for choosing the New event option in the text event section.

    • Choose the Save changes and then choose Test.

AWS Lambda offers services that enable the save changes and further choosing text.

    • View the results in console upon the successful completion,

AWS Lambda offer services for viewing the results in the console upon successful completion.

    • Run the function (choose Test) a few more times to get some metrics

AWS Lambda offers services providing the option to run the function a few more times to get the metrics.

Finally, AWS Lambda provides the Choose with the Monitor tab option.
