Prototype for Production

Use FOSS smartly to Deliver your ideas with

Speed and Quality

What’s in it for you?

● If you have an Idea and want to launch it in a

week with production quality using free &

open source tools.

● If you are a DevOps looking for code

snippets of real life usage cases.

● ...Or..

..or.. If you just love to hear about

Django

NLP

Ansible

LibreOffice

AngujarJS

REST APIs

Postgresql

Editors

Supervisord Diagram Tools

Nginx+Uwsgi Test Reports

Trello

Git

Agile, Business Model Canvas…

…. & Simple common sense ;-)

Who am I?

Let’s divide and rule!

Phase 1: Things about IDEA

Phase 2: Things about Execution

Phase 3: Continues Improvements

Abstract to Actionable

Phase1 : IDEA

Business Model Hypotheses

http://practicetrumpstheory.com/businessmodelcanvas/

(Lean) Business Model Canvas

http://www.leanstack.com/

Do's &

Dont’s

● Iterate multiple times

● Iterate in parallel

● Let whole team agree

on BMC

● Don’t create BMC with

hi-fi tools (just use

docs/whiteboard)

● Don’t complicate single

BMC

Actionable to Measurable

Phase2 : Execution

Trello : Boards that Boosts!

Trello : Boards that Executes ;-)

GIT : branch me if you can

- Master based git development

- “master” => always ready for Production.

- use “develop” branch as working branch

- each branch must represent fully working release..

- else .. Don’t branch!

- use Feature Flags

The real meat: Django!

● One of the best frameworks which provides

out of the box Production readiness

● One of the best doc, from where copy

pasted code can actually work in production!

● Lot of extension points:o Make it work first => then make it correct.

● Django is awesome: o but will talk about only few relevant features to

highlight integration

Data Migration : Git for database!

● Django is serious about migrationo Auto migration

o Full manual mode

PostgreSQL : Pinnacle in FOSS DB

● “Use Blue elephant before trying out Yellow elephant” - @yourfrienddhruv

● Again, talking about only few PostgreSQL thing here

● Full Text Search

o Without writing Lot of code, without running external services!

o https://github.com/niwibe/djorm-ext-pgfulltext

o Full pros/cons

Ansible : Git for Infrastructure!

● Cool as git

● Simple as SSH

● Works as puppeto but does it install like puppet :Hell NO!

● Template like Markdown

● Modularize like Django

I see docker there: Yes but not enough time to talk about it now, Sorry!

Ansible : Templatize configuration

dbname: myAppDB

dbuser: myAppDBUser

[webservers]

webserver1

webserver2

hosts file vars file

SupervisorD: Integrating with Non

Python Stuff

● Run java service in background

Measure to Take Action

Phase 3 : Continues

Improvement

Learning: There is no separate phase-3

Phase 3 :

Execution tools/Design

must support Continuous

Improvement

Few quick things helps you measure

● Measure Python API performance!o Google UA python Tracker

o Actually you can send some meta data too ;-)

o P.S: For production kindly use reverseAsyncProxy to avoid slowdown

in case of slow HTTPS calls to GA.

PsDash : Monitor ThingsMonitor live process, Load Avg, Open Files, Network state, Disk Space,

Even tail & search logs!

QA:Test and Report Business Cases

Use even simple tools:

Write simple Shell/Python script to invoke Django CLI custom

commands to trigger tests which produces Json Results
