Basic architecture

This section describes the basic architecture of SOULs Functions.

rspec

The big picture of SOULs Functions

SOULs use Google Cloud Functions.

Google Cloud Functions

  • No server provisioning, management or upgrades required
  • Automatic scaling according to load
  • Integrated monitoring, logging and debugging capabilities
  • Per-role and per-function levels of built-in security based on the principle of least privilege
  • Key networking features for hybrid and multi-cloud scenarios

By using Cloud Functions in SOULs, you can create applications not only with Ruby but also with Node.js , Python , and Go .

Runtime Versions
Ruby 2.7, 2.6
Node.js 16, 14, 12, 10
Python 3.9, 3.8, 3.7
Go 1.16, 1.13

Directory structure of SOULs Functions

Interactively with the souls create functions command

Select the runtime and version,

Automatically generate the files needed to deploy Cloud Functions.

$ souls create functions ${method_name}

SOULs Functions creates multiple Cloud Functions.

The function directory name is

cf-${Runtime}-${Function}

Runtime Version Function
Node.js 16 method1
Python 3.9 method2

The folders name will be

cf-node16-method1

cf-python39-method2

Once done,

It will be automatically generated if you need to go to the front CloudFuncion.
