问题 I'd like to define a lambda. When it receives a POST request, I'd like to make another POST request to an external uri (say, splunk or apigee or anything outside of AWS). Is this possible? Does Lambda allow the internet access? I googled but did not find a good answer for this one. 回答1: Yes, you can run pretty much any code that you would run on a normal EC2 instance. For instance, if you write your Lambda in node.js you can use the request library to make HTTP calls out to other webservices.

问题 I would like to retrieve some meta data I added (using the console x-amz-meta-my_variable) every time I upload an object to S3.

问题 I would like to be able to send data sent to kinesis firehose based on the content inside the data.
