λ(x) triggered by object upload to S3

A simple example to analyze research data in the cloud using AWS

Background

This is an efford to show how simple use of DevOps tools in new resources in cloud computing can bring a innovative way to analyze data. Using cloud computing the simplest analysis of everyday experiemntal data can quickly be accompish accelerating the work flow.

What it does?

This example uses excitation spectrum data. The lambda function (./function/main.py) contains a python script that will read an csv file from S3 bucket (source_bvc_files/data/) and find the maximum of emission intensity. Then, the maximum intensity and wavelength are saved in a different bucket (source_bvc_filesanalyzed/data/).

The function is triggered as soon a file is saved in the source bucket (source_bvc_files/data/).

Provisioning

The AWS resources required to have this function are provisioned using terraform (./infrastructure/terraform/).

How to use it?

  • Clone this repository
  • cd infrastructure/terraform/
  • Check what resources will be created terraform plan
  • Provision resources terraform apply *Login to AWS console and check the s3 buckets, lambda function and its logs.
  • cd ../function/
  • Upload files to S3 aws s3 cp --recursive ./data/ s3://source_bvc_files/data/
  • Check again the buckets you will see the analyzed files!!!

Et Voilá!
