Final answer:
AWS Lambda isolates your code using containers, virtualization technology, and IAM roles.
Step-by-step explanation:
AWS Lambda isolates your code using a combination of techniques to provide a secure and reliable environment for your applications. First, each Lambda function runs in its own isolated environment, called a container, which is completely independent of other containers running on the same infrastructure. This ensures that your code is securely isolated from other code running in the same AWS Lambda service.
In addition, AWS Lambda uses virtualization technology to provide further isolation between Lambda functions. Each function is executed in its own dedicated computing environment, which is isolated from other functions and customers' functions.
Lastly, AWS Lambda provides security through the use of AWS Identity and Access Management (IAM) roles, which allow you to define fine-grained permissions for your Lambda functions. You can control which AWS resources your Lambda function can access, ensuring that your code is isolated from sensitive resources or data.
