Software energy consumption
is on the rise

The Internet and its online services now account for more than 7% of the planet's electric consumption. Usage continues to grow extremely rapidly while energy consumption increases almost linearly with usage.

Taking corporate responsibility seriously

Taking corporate responsibility seriously

As developers, it's not possible to ignore the problem of sustainability. As a company providing online applications and services for users, we must also make a commitment to reverse the trend.

The levers for action exist. Application architecture and design, technologies used, data collected, bandwidth used, etc., many elements have a significant impact on the energy footprint of your applications.

Today, most large companies are committed, at all levels, to reducing their indirect greenhouse gas emissions. This constraint applies to all departments, including IT.

However, CIOs are currently focusing on the use of data centres supplied with more renewable energy and limiting the usage by users. In order to have a real impact, the scope of action must be extended:

  • to the design of applications.
  • to the choice of energy-efficient applications.
  • to development approaches that integrate energy issues from the design stage, with partners who are aware of this process.


Smaller energy footprint means good design

Smaller energy footprint means good design

Fortunately, all of these drivers contribute to turning good energy practices into a competitive advantage:

  • Cost: Reducing the energy footprint of your application also reduces your operating costs, in particular by keeping machine usage, energy consumption, storage, bandwidth, etc. under control.

  • Maintainability: The most efficient applications are those whose architecture has been designed to be minimalist, efficient and maintainable.

  • Good level of granularity of the architecture: In the age of micro-services, it is not always easy to find the right level of granularity for the breakdown of our applications. The right level from a design point of view is usually at the point of maximum efficiency.


How can you reduce the energy footprint of your application?

ProcessOne helps you to act on several dimensions.




Benchmark and Diagnostic

Benchmark and Diagnostic

In order to define a remediation strategy, it's critical to measure the energy efficiency of an application and to map the most energy consuming areas. ProcessOne conducts performance tests that can:

  • Measure the raw performance of an application, its architecture and infrastructure, and identify breakpoints (number of simultaneous users, number of requests per second, bandwidth, etc.).
  • Evaluate the energy efficiency of the service.
  • Map the most energy-intensive spots.
  • Calculate the operating costs, before being able to build a business case to finance the energy optimization of the application.

Optimization

Optimization

Optimization is an iterative process, carried out with the client's development team. The goal is to target the hot spots:

  • By working on the service architecture to make the most demanding operations modular.
  • By adjusting the technologies used, in order to change the overall energy efficiency of the platform.
  • By optimizing the algorithms.
  • By re-engineering processes to optimize usage.

Measurement and Iteration

Measurement and Iteration

The benchmark must be repeated after optimization to measure the optical impact in terms of gross performance, energy balance and operating cost reduction. Depending on the target result, another round of optimization can be carried on.
