AWS Lambda Overview

AWS Lambda is the #2 ranked solution in our list of top Compute Service tools. It is most often compared to AWS Batch: AWS Lambda vs AWS Batch

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).

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.

Good user experience through the console but needs additional integrations, better interface

What is our primary use case?

I back up my MongoDB, that database has user data. The performance of AWS Lambda has been fine.

Pros and Cons

  • "Provides a good, easy path from when you're using an AWS cluster."
  • "I would like to see some better integration with other providers, like Cohesity, Druva, and others. I also think the Lambda interface could be better."
  • "The setup was pretty complex because there were many steps. For me, it was complex because I was somewhat new at it. It could be easier for someone who has done it a bunch of times. I just found that it was a very dense user experience. There's a lot going on during setup."

What other advice do I have?

My most important criteria when selecting a vendor are * user experience * support. I would rate AWS Lambda at a six out of 10 because it's not quite clear that it scales, but it does have a good, easy path from when you're using a cluster.

Develops release pipeline faster but no shell script is supported

What is our primary use case?

1. Use lambda function to trigger the jenkins jobs to make whole release pipeline. 2. Send the slack notification once the release with automated test is done.

What other advice do I have?

For automation developers, we do not care too much about which CI system we use. It does not affect us too much. Automation tests can be ran in most of mainstream CI systems.
