How does AWS Lambda handle scaling automatically?
- By adjusting the number of function instances based on incoming requests
- By increasing the memory allocation of functions
- By limiting the number of requests per function
- By manually configuring scaling policies
AWS Lambda automatically scales by adjusting the number of function instances to match the incoming request volume, ensuring that there are enough resources to handle the workload.
What happens when multiple requests are received simultaneously by an AWS Lambda function?
- AWS Lambda creates separate instances of the function to handle each request concurrently
- AWS Lambda queues the requests and processes them sequentially
- AWS Lambda randomly selects one request to process and discards the rest
- AWS Lambda rejects the additional requests until previous ones are processed
When multiple requests are received simultaneously, AWS Lambda creates separate instances of the function, allowing each request to be processed concurrently without impacting others.
What are some factors affecting the scalability of AWS Lambda functions?
- Concurrent executions
- Function duration
- Memory allocation
- Network bandwidth
The number of concurrent executions allowed for a function can affect its scalability, as high concurrency can lead to resource contention and increased latency.
What is the default concurrency limit for AWS Lambda functions?
- 1000
- 2000
- 250
- 500
The default concurrency limit for AWS Lambda functions is 1000, which represents the maximum number of concurrent executions allowed for all functions within an AWS account.
How can you adjust the concurrency settings for an AWS Lambda function?
- Contacting AWS support
- Editing the function code
- Programmatically using AWS SDK
- Using the AWS Management Console
You can adjust the concurrency settings for an AWS Lambda function through the AWS Management Console, allowing you to control the maximum number of concurrent executions.
