« Windows, it’s slow »

« My computer is 2 years old,

it isn’t up to date »

Software : the first reason

of changing hardware the

first reason of equipment’s

obsolescence

Hardware context…

« Software is getting slower more

rapidly than Hardware becomes faster»

Wirth’s law

The bloatware …

« We are living in a finite world where

we will be more and more to share

resources and energy which

are more and more rare, so more

and more expensive »

Eco-design for software: an obvious!

An infinite IT world :

Big data

Very High Definition

Faster interactivity

Mobility

An important rise in the number of internet users

and services

The race for more powerful hardware, more thrifty is “the default

solution”

Eco-design for software is becoming an obvious

For ecologic and sustainable economic gains10

Eco-design: Green Software is $Green !

Energy savings

Extending IT equipment life time

Reduce IT costs : less purchase of

equipment, software licenses & space

“Economic scalability” for an increased

load

Profits thanks to the performance, and to

the autonomy on constrained or nomad

systems

Societal responsibility for your IT developers

Giving value on your product or service for

your customers11

Example of a Green pattern Taking into account the context

1 watt in addition to the minimization of the window or tab

Green pattern : at the minimization of a window: No more treatment

Avoiding waste

8 reasons to do Eco-design for Software with Greenspector® !

1. Finds on millions lines of codes consuming patterns

2. Brings solutions to correct these codes

3. Rules validated and based on measurement from an independent research

laboratory

4. Multi-language (Java, PHP, JS, CSS, HTML, SQL, C,…)

5. Shows the gains and refactoring time for each rule helps to decide and to

plan

6. For project manager (management indicators, multi-applications’ view,

reporting, level change over time) & developer (integrated on Eclipse, Sonar)

7. Quick spread into the organization, without technical training nor specific

equipment

8. Scalable in price & to fit all companies 33
