Enterprise Service Bus is still a pretty vague term, first introduced in the Gartner Report of 2002.

It is essential for running a large SOA infrastructure.

Our interpretation of what an ESB should consist of:

• Service Abstraction / Metadata Definition
• Centralized Service / API Registry containing clean XML, JSON Model
• Centralized Service AAA (Authentication / Authorization / Accounting)
• Internal Service XML / (Python) Class Mapping
• OOP Relational Database Mapper
• Service Model Documentation / API (Auto)-Generation

# setup virtual-env
python3 -m venv .micro-esb

# activate virtual-env
source .micro-esb/bin/activate

# upgrade pip
python3 -m pip install --upgrade pip

# install microesb module
pip3 install microesb

# install dependencies
pip3 install pytest pytest-pep8

Building web applications on PaaS infrastructure also relies on a clean Service Abstraction Model.

Note The Python micro-esb module will help.

• Service Abstraction / Metadata Definition
• Internal Code (Python) Class / Service Properties Mapping
• Graph-Based / Recursive JSON Result Abstraction

• OOP Relational Database Mapper
• Service Documentation (Auto)-Generation

Documentation, including detailed examples, can be found either in the ./doc directory or at: https://pythondocs.webcodex.de/micro-esb
