BUSINESS CASE Juri di Natale

LINKME à agile development ENTER CLOUD SUITE à cloud computing CROWDCORE à crowd economy


THE “PROTAGONISTS”


SOME DEFINITIONS, BEFORE WE START

•  MongoDB •  ExpressJS •  AngularJS •  NodeJS


WHAT IS M.E.A.N.

•  Reward crowdfunding •  Equity crowdfunding •  Donation crowdfunding •  Pre-order crowdfunding •  Social lending


CROWDFUNDING

A framework to develop crowd economy tools and platforms


CROWDCORE

CROWDCORE for NTT DATA


CROWDECONOMY

Customers are creating new business models


PLATFORM CHARACTERISTICS •  Multiplatform •  Multiproject •  Set of tools specific to different

types of crowdfunding •  Custom application

How cloud computing and M.E.A.N. supported the development of a framework for a crowd economy platform


BUSINESS CASE

1. Scalability 2. Agile new feature implementation 3. Component re-use


THE CHALLANGE


CROWDCORE APPLICATION


BACKEND Giovanni Lela

•  I/O intensive REST APIs •  Horizontal scalability •  Leverage existing javascript know-

how •  Huge community


WHY

•  (mostly) non relational data •  Horizontal scalability (again) •  Mongoose ODM


WHY

•  Unopinionated •  VERY modular •  Mature


WHY


6 MONTHS LATER…

•  You need something to fight the callback hell (Bluebird)

•  Needs static typing •  Too many community packages

are too many


nodeJS IS OK BUT…

•  Mongoose Schemas are great o  Valida&on o  Referencing other documents o  Schema inheritance o  Plugins


mongoDB and mongoose ARE OK BUT…

•  Easy to extend •  Maybe too much unopinionated


EXPRESS IS OK BUT…

•  Typescript •  ES6 generators - koa

WHY ANGULAR

Every components is assembled with a Directive and a Service

STANDALONE MODULES

Directive

Template

MODULE CONFIGURATION

GruntJs let us build portable environment and tailor them to the developer needs.


DEV ENVIRONMENT

Every Module has his own repository, that is importend in the main project as a Git SubTree


VERSION CONTROL


SIX MONTHS LATER…


Modules à Web Components


Grunt à Vagrant

Subtree à Private Bower Registry


Q&A


HOW WE DESIGNED THE INFRASTRUCTURE Giorgio Bonfiglio

•  Cost effectiveness •  Ability to scale-up


WHAT THE CUSTOMER ASKED FOR…

•  (Very) short deployment time •  Standardized processes •  Ability to clone the infrastructure


…AND WHAT ABOUT DEVELOPERS?

•  Designed for the cloud •  Easier distribution of components


NEW FRAMEWORKS, BETTER POSSIBILITIES


HERE IT IS

“deploy and scale in seconds easily manageable building blocks”


IT’S ALL ABOUT AGILITY

•  Easy disaster recovery, replica and versioning: NO limits!


DREAMS… AS A SERVICE

•  Infrastructure awareness for the application

•  Platform APIs enable it to control the underlying layer


WHAT’S NEXT?


Q&A


KEY FINDINGS

•  Technology supports the crowd economy

•  MEAN provides high scalability and flexibility

•  Cloud native applications do “manage” cloud infrastructures
