How to create Lambda Function in AWS

To create 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:

Log into Your AWS account: Choose Lambda in Management console: Create a new Lambda function:

Give the details for the function: Select the role: To create a new role select the AWS service and continue the process: Select the existing role:

Make some changes in code and deploy the changes: Then run a program by clicking Test: Enter the Event name: Again run a program: Then, check the execution status: With This method creation of Lambda Function comes to an End.

FAQ
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.
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
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
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.
