Create an AWS lambda function from scratch using Python, configure execution role, use an existing role or create one, and test and deploy code with the built-in editor.
Learn how to create an AWS Lambda function from scratch, select Python, and configure an execution role to grant access to other services like S3; test, deploy, and iterate.
Dockerize a Node.js Express app and test it locally. Push the container to Amazon ECR and run it on an EC2 Linux instance exposed on port 3000.
Learn how to push to AWS ECR from an EC2 instance by configuring Docker, logging into ECR, and pulling containers, while troubleshooting permission and connection issues.
Set up an AWS EC2 Linux instance, start Docker, login to ACR, pull and run the container, and map port 3000 while configuring security group rules for internet access.
Fetch the ECR image to an EC2 Linux instance, dockerize and run the container, map port 3000, and access the Node.js express API via http while configuring security groups.
AWS Lambda is a server less computing service provided by Amazon Web Services (AWS). It allows you to run your code without provisioning or managing servers. With Lambda, you can focus on writing the code for your application while AWS handles the underlying infrastructure and scaling.
Here are some key features and concepts related to AWS Lambda:
Function Execution: Lambda allows you to upload your code as a function, written in languages such as Node.js, Python, Java, C#, or Go. The code is divided into small, self-contained units called functions, which can be triggered by events or invoked directly.
Event-driven Architecture: Lambda functions are typically triggered by events such as changes in an Amazon S3 bucket, updates to a DynamoDB table, or incoming messages from Amazon SNS or AWS IoT. When an event occurs, Lambda automatically executes the associated function.
Lambda has become popular for a variety of use cases, such as web applications, data processing pipelines, real-time file processing, IoT backends, and more. Its server less nature and event-driven model make it flexible and scalable for different types of workloads.
