What is AWS Lambda?

AWS Lambda is a compute service that lets you run code without provisioning or managing servers. AWS Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second. You pay only for the compute time you consume - there is no charge when your code is not running. With AWS Lambda, you can run code for virtually any type of application or backend service - all with zero administration. AWS Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. All you need to do is supply your code in one of the languages that AWS Lambda supports (currently Node.js, Java, C# and Python).

We use AWS Lambda because it provides a solution for our needs without requiring us to manage our infrastructure. With the tool, we only pay for the resources we use. Additionally, it is straightforward to implement and integrates with other services like API Gateway. The tool's serverless nature has had the most significant impact on our workflow. I find it particularly attractive because it eliminates the need for managing servers. In my previous experience, managing upgrades and updates was quite challenging. The solution's integration process with other AWS services was relatively easy. We primarily use AWS services such as EventBridge for scheduling processes and log management.

One area where AWS Lambda could be improved is the execution timeout limit, which is currently capped at 15 minutes. This is restrictive for tasks that require longer processing times, such as complex data analysis or large-scale batch processing. Additionally, the environment customization is limited, particularly with regard to file system access, persistent storage, and certain execution capabilities, which can be restrictive for more advanced use cases. Another area for improvement is the cold start latency, which can add significant overhead to the execution time, especially for applications with infrequent or unpredictable invocations. For future releases, it would be helpful if AWS Lambda allowed for longer execution times or offered an option for more flexible execution environments. Reducing cold start latency or offering features like provisioned concurrency with more granular control could also help improve the overall performance and responsiveness of Lambda functions.

Having a better preview would be helpful. Sometimes, if my Lambda code is too big, it can be inconvenient as I'm unable to see my code when it exceeds a certain size. AWS has a limit, like a three-megabyte limit, beyond which I cannot view or edit the code easily.

Valuable Features

"Lambda allows you to focus on the code itself."
"The fact that it is serverless is really important."
"What I like most about AWS Lambda is that it's very easy to deploy."

Room for Improvement

"Having a better preview would be helpful."
"The runtime could be improved. There are certain use cases where I need a Lambda function to run longer."
"The way Lambda works with HTTP headers is a bit odd."

Pricing

"AWS Lambda is not expensive for micro testing but is expensive if used for long deployment or long services."

Learn more about AWS Lambda

You can use AWS Lambda to run your code in response to events, such as changes to data in an Amazon S3 bucket or an Amazon DynamoDB table; to run your code in response to HTTP requests using Amazon API Gateway; or invoke your code using API calls made using AWS SDKs. With these capabilities, you can use Lambda to easily build data processing triggers for AWS services like Amazon S3 and Amazon DynamoDB process streaming data stored in Amazon Kinesis, or create your own back end that operates at AWS scale, performance, and security.
