To Ceate Lambda Function in AWS

Introduction

AWS Lambda is a serverless measure service that runs code in response to events and spontaneously runs the underlying compute resources. Lambda runs the code only when needed and scales automatically, from a few requests per day to thousands per second. It also extends other AWS services with custom logic or creates its own back-end services that operate at AWS scale, performance, and security.

Steps to Create Lambda Function:

Ste 1:- Log into your AWS account SNAP 1

Step2:- Choose Lambda in Management console SNAP 2

Step3:- Create a new Lambda function SNAP 3

Step4:- Give the details for the function SNAP 4

Step5:- Select the role SNAP 5

Step6:- To create a new role, select the AWS service and continue the process SNAP 6 SNAP 7 SNAP 8 SNAP 9 SNAP 10

Step7:- Select the existing role SNAP 11

Step8:- Make some changes in code and deploy the changes SNAP 12

Step9:- Then run a program by clicking Test SNAP 13

Step10:- Enter the Event name SNAP 14

Step11:- Again, run a program SNAP 15

Step12:- Then, check the execution status SNAP 16

Conclusion:

We have reached the end of this article. In this guide, we have walked you through the steps required to Create Lambda Function on AWS. Your feedback is much welcome.

Q

What is AWS Lambda?

A

AWS Lambda is a serverless measure service that runs code in response to events and spontaneously runs the underlying compute resources. Lambda runs the code only when needed and scales automatically, from a few requests per day to thousands per second. It also extends other AWS services with custom logic or creates its own back-end services that operate at AWS scale, performance, and security.

Q

How does AWS Lambda secure my code?

A

AWS Lambda stores code in Amazon S3 and encrypts it at rest. AWS Lambda performs additional integrity checks while your code is in use.

Q

What languages does AWS Lambda support?

A

AWS Lambda natively supports Java, Go, PowerShell, Node.js, C#, Python, and Ruby code, and provides a Runtime API that allows you to use any additional programming languages to author your functions. Please read our documentation on using Node.js, Python, Java, Ruby, C#, Go, and PowerShell.

Q

What if I need scratch space on the disk for my AWS Lambda function?

A

Each Lambda function receives 500MB of non-persistent disk space in its own /tmp directory.

Q

Can I use threads and processes in my AWS Lambda function code?

A

Yes. AWS Lambda allows you to use normal language and operating system features, such as creating additional threads and processes. Resources allocated to the Lambda function, including memory, execution time, disk, and network use, must be shared among all the threads/processes it uses. You can launch processes using any language supported by Amazon Linux.
