Performance Testing for Serverless Architecture (AWS)

Introduction

This document provides a brief description of how JMETER can be used with a server-less architecture like AWS. This can be used to evaluate the read/write capacity of the underlying DB, to benchmark the load an application can survive with.

What are AWS Lambdas?

The code written is deployed to AWS lamba over the cloud with one or more lambda functions. A compute service runs the code on our behalf.

AWS Lambda Automated Deployment

Objective

This blog details the steps to build, deploy and maintain different versions of Lambda functions across various product stages such as development, testing, staging and production on multiple AWS accounts.

AWS Lambda Versions and Aliases

AWS Lambda lets you run code without provisioning or managing servers. You are charged based on the time and resources consumed by your code when it runs – there is no charge when your code is not running. All of this makes AWS Lambda very easy to jump straight into your business logic and not worry about the infrastructure setup. But since this is a “server less architecture”, code deployments for your various stages is a bit different than what you are used to. Let’s look at how to manage staging with the help of Lambda Versions and Aliases.
