Customer Success Story : Quota Climat

Thanks to Scaleway, Quota Climat was able to optimize technical management, reduce costs and deliver the product in time for its launch in November 2024.

Missions

The initial observation stems from media coverage of environmental issues that could be improved both in quantity and quality.
To better address this observation, we have come together as a consortium of associations around Climat Medias, Quota Climat, Expertise Climat, and Data For Good to provide public, reliable, and transparent data on the state of media coverage of environmental crises through a digital "commons": L’Observatoire des Médias sur l’Écologie.

Challenges

This project was both a human and financial challenge, with the following issue: how to ensure sustainability, robustness, eco-design, and maximize the impact of a tool with a limited budget and a very small tech team?

No miracle solutions—just focusing on the essential need: measuring environmental issues in the media on a daily basis. This required avoiding devoting our small resources to server management and efficiently handling a microservices architecture.

That's where the beta release, followed by the general availability of Scaleway's Serverless Jobs service, saved us precious time. It allowed us to deliver the product on time for a major launch event in November 2024, attended by our partners such as ARCOM, ADEME, and distinguished guests like Jean-Marc Jancovici and David Colon.

During the development of the service, the team appreciated the responsiveness and interactions on Scaleway's public Slack, which gradually evolved into a true relationship of trust over the months.

Architecture

Our deployed application is based on our code versioned on GitHub. When changes are made in the repository, we leverage continuous integration through GitHub Actions to update the images on Scaleway's Container Registry.

From there, with our various application images on the registry, we can configure the "Serverless Containers" services - linked to web applications - and "Serverless Jobs"—for deferred computations- with just a few clicks.

Beyond the convenience of the production deployment process, using a serverless service allows us to pay only for usage, optimizing our infrastructure costs.

To further optimize costs with Serverless, we quickly implemented a system (via the Scaleway CLI) that allows us to adjust the scaling of our resources based on different times of the day.

Ecodesign of digital services - architecture

In terms of eco-design for digital services, which should be clearly distinguished from optimization, we were able to meet the goal of avoiding an oversized architecture and prioritizing one that dynamically adjusts the amount of resources used based on service demand. This also allows us to scale up when larger computations are required.

Looking at the numbers, we launched a thousand Serverless Jobs in 2024, with varying levels of power (it's possible to allocate CPU and RAM according to the specific needs).
Take aways

By adopting Serverless products, we were able to automate task execution without managing the underlying infrastructure. Specifically:

  • Eliminating unused servers: Resources are dynamically provisioned with Serverless Containers and Jobs, everything is managed based on demand, reducing energy waste.
  • Improved scalability: A key strength of Serverless products is their ability to automatically adapt to load, efficiently handling demand spikes or consuming no resources when the infrastructure is idle.
  • Cost reduction: Paying only for actual usage is an excellent way to optimize costs. However, the most significant factor in the equation is the lack of maintenance required for complex resource orchestration systems.
  • Simplicity: This time-saving approach allows the team to focus on development, innovation, and project engagement rather than server maintenance. Resources are flexible, monitoring and logs are integrated, and there’s nothing else to manage. Networking, security, and scalability aspects are all handled.

Future plans

The adoption of Serverless Jobs and Serverless Containers has undoubtedly contributed to the success and will continue to contribute to the future successes of L’Observatoire des Médias sur l’Écologie. Not only have we improved our operational efficiency, but we have also aligned our technological infrastructure with our sustainability ambitions.
