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.
AWS Lambda automatically manages __________ to accommodate varying workloads and optimize resource utilization.
- Billing
- Networking
- Scaling
- Security
AWS Lambda automatically scales to accommodate varying workloads by provisioning the necessary compute resources, optimizing resource utilization, and ensuring efficient cost management.
When designing AWS Lambda functions for high concurrency, it's essential to consider the impact on __________ and resource consumption.
- Cost
- Latency
- Performance
- Security
When designing AWS Lambda functions for high concurrency, it's essential to consider the impact on performance and resource consumption.
AWS Lambda provides __________ concurrency limits per region by default.
- Account-based
- Function-based
- Global
- Region-based
AWS Lambda provides account-based concurrency limits per region by default.
To control concurrency in AWS Lambda, you can set __________ at the function level.
- Execution role
- Memory allocation
- Reserved concurrency
- Timeout duration
Reserved concurrency allows you to limit the number of concurrent executions of a function, helping you control costs and resource utilization in AWS Lambda.
Strategies such as __________ can help mitigate issues related to cold starts and concurrent execution spikes.
- Auto scaling
- Elastic load balancing
- Provisioned concurrency
- Static scaling
Provisioned concurrency allows you to preallocate resources to a function, reducing cold starts and mitigating issues related to concurrent execution spikes in AWS Lambda.
When architecting for high concurrency, it's crucial to design for __________ to ensure efficient resource utilization.
- Microservices architecture
- Monolithic architecture
- Stateful functions
- Stateless functions
Designing functions to be stateless allows them to scale horizontally and efficiently handle high concurrency in AWS Lambda, ensuring optimal resource utilization.
