The lambda service supports Java, Node.js, C#, Python, and Go languages. Once you create, the next step is to implement it. Upload your code, and configure the execution environment. Then, the code executes within a fully managed computing environment. **Table of contents** 1.

[Steps to create Lambda function](https://srinimf.com/2022/06/04/exclusive-how-to-add-lambda-tool-to-aws-services/#5.-Steps-to-create-Lambda-function) ## **AWS Lambda** The features of lambda. - Offers a maintenance-free and highly available computing environment. - You no longer need to install security updates, replace failed virtual machines, or manage remote access (such as SSH or RDP) for administrators. - It is billed by invocation. Therefore, you don’t have to pay for idling resources that are waiting for work (for example, for a task triggered once a day). ## **Lambda is Serverless** - It is a Serverless, event-driven computing service. - Maintenance is not needed. So it is called serverless. No need to manage and maintain virtual machines. - Fully managed service offering scalability and high availability. - Billed per request and by resource consumption. Invoke the function to execute your code in the cloud. Advertisements ## **[Lambda Vs](https://srinimf.com/2024/10/15/aws-lambda-vs-step-functions-key-differences-explained/) EC2** Here are the differences between EC2 and Lambda - Virtual machines provide a full operating system for running one or multiple applications. In contrast, AWS Lambda offers an execution environment for a single function, a small part of an application. - Amazon EC2 offers VMs as a service, but you are responsible for operating them in a secure, scalable, and highly available way. By contrast, AWS Lambda offers a fully managed execution environment. - AWS Lambda is billed per execution, and not per second a virtual machine is running. ## **Blueprint in AWS** Blueprints are sample code templates. You can use them for your first lambda function. ## **Steps to create Lambda function** 1. Visit Blueprints to get the sample code 2. Search for Lambda==> Function==> Create function 3. Fill basic details 4. Create a new IAM role [to write](https://srinimf.com/2024/09/08/aws-3-easy-to-write-lambda-functions/) your Lambda function details to cloud watch 5. Create a cloud watch event 6. Map the rule name in Cloud watch is the same as Lambda function name That’s it you can watch your **lambda function work in Cloud watch**.
