Running nightmare on Amazon Linux

You may have thought of running nightmare on AWS Lambda. But before we can run it on Lambda, we need first to make it run on Amazon Linux.

Provision instance which replicates Lambda environment

According to AWS Documentation on Lambda Execution Environment and available Libraries we would need this AMI image with this alias amzn-ami-hvm-2016.03.3.x86_64-gp2. Keep in mind that AMI-image-id for this instance would be different in different regions (eg):

• In eu-west-1 - ami-f9dd458a
• In us-east-1 - ami-6869aa05

Installing Node.js on Amazon Linux AMI

The following will guide you through the process of installing Node.js on an AWS EC2 instance running Amazon Linux AMI 2016.09 - Release Notes

For this process I'll be using a t2.micro EC2 instance running Amazon Linux AMI (ami-d41d58a7). Once the EC2 instance is up-and-running, connect to your server via ssh

• Make sure our server has the latest packages : sudo yum update -y

Motivation

Allow developers to specify workflows without the need for installing additional tooling such as a modeler.

Goals

• It should be easy to define a simple workflow with a text editor only
• The format must map down directly to BPMN
• The format must be based on an existing text based format like (XML, JSON, YAML, TOML, ...)
