Measuring employee trust at scale

Its approach is based on a simple idea: trust is a key driver of performance and engagement at work. To measure this trust, Great Place To Work relies on a research-based methodology and a standardised questionnaire designed to assess employee experience.

The collected responses enable organisations to:

• identify strengths and areas for improvement
• benchmark their results against their industry
• guide their HR strategy using concrete data

At the core of this model lies a critical element: data directly collected from employees’ perceptions.

In this context, data reliability and confidentiality are essential to the credibility of the service.

Data at the core of the Great Place To Work model

Great Place To Work surveys are built on a fundamental principle: allowing employees to express themselves freely and anonymously. The responses feed analyses that help organisations improve their work environment and management practices. This approach is based on a structured methodology, relying on around sixty questions designed to assess different dimensions of trust within an organisation.

For Great Place To Work teams, data is therefore the foundation of their entire activity.

Survey responses are collected through Great Place To Work’s global tools. The French teams then use their own analysis and reporting tools to make results accessible to client organisations. In this context, hosting infrastructure becomes a key component of the overall value chain.

Data hosting: why Great Place To Work chose Clever Cloud

Great Place To Work France has been using Clever Cloud since 2018 to host part of its applications. Choosing an infrastructure provider is not just a technical decision. It also plays a role in building trust with client organisations.

These organisations rely on Great Place To Work to handle data related to employee perception, and expect strong guarantees in terms of security and confidentiality.

Several factors help explain the choice of Clever Cloud.The first relates to data sovereignty. The ability to host applications on a French cloud is a key factor for corporate clients who wish to ensure that their data remains within the European regulatory framework.

The second criterion concerns infrastructure security. ISO 27001:2022 and HDS (Health Data Hosting) certifications, along with the technical guarantees associated with the hosting service, help to reinforce the platform’s credibility with corporate clients.

Finally, operational simplicity also played a decisive role. As Great Place To Work France’s technical team is relatively small, the aim was to minimise the complexity involved in managing the infrastructure as much as possible.

Operating a PaaS with a small technical team

Today, the technical teams rely on Clever Cloud primarily through automation. Deployments are automatically triggered when code is pushed to the Git repository, significantly simplifying production workflows and reducing manual intervention.

This approach helps:

• streamline deployments
• reduce human error
• accelerate delivery cycles

The team also runs its own monitoring tools on the platform, providing a global view of application health and enabling faster incident detection. In practice, Clever Cloud allows Great Place To Work teams to focus on their applications rather than managing infrastructure.

Continuous deployments with minimal operational effort

Some Clever Cloud features are particularly valuable in day-to-day operations. This is especially true for Blue-Green Deployment, which enables safer and more efficient release processes.

This capability allows teams to deliver updates continuously with very little effort, while reducing risks associated with production releases. The platform also supports both vertical and horizontal scalability, which currently meets the organisation’s growth needs.

Advice from Nicolas Moreau to CIOs

For organisations considering moving to a sovereign cloud, Nicolas Moreau recommends starting with experimentation.

According to him, the key is to choose an infrastructure that genuinely simplifies day-to-day operations, allowing teams to focus on what matters most: product and value delivery.

Infrastructure as a foundation for trust

For Great Place To Work, infrastructure is not just a technical layer. It directly contributes to the trust placed in the organisation by both clients and survey participants. Security, sovereignty and reliability all play a role in ensuring that collected data is handled in a transparent and controlled environment.

In a model where data reflects employee perception, this trust is fundamental.By relying on a sovereign cloud and a PaaS platform designed for simplicity, Great Place To Work teams can focus on their core mission: analysing data and helping organisations improve employee experience over time.

Building digital sovereignty as a trajectory, not a posture

Rather than claiming an ideal stance or a “100% sovereign” label, Badsender chose a different path: transparency. The agency publicly documents its IT stack, openly acknowledging inconsistencies and dependencies, and explaining the trade-offs behind each decision. This approach is not about claiming perfection, but about creating a compass to guide future technical choices.

Open source as the foundation of sovereignty

For Badsender, the reflection quickly went beyond the simple question of hosting providers.

This reasoning is fully aligned with Badsender’s DNA: sharing knowledge, documenting practices, and building tools that can be reused by others. It is within this mindset that LePatron was created—an open-source email builder designed to simplify the creation of responsive emails that comply with industry best practices. One key question then remained: where should this web application be hosted in a way that is consistent with these principles?

Why Clever Cloud to host LePatron

From a technical standpoint, LePatron relies on a well-controlled architecture: a Node.js web application, a MongoDB database delivered as DBaaS, and asset hosting. Users are mainly located in Europe, but also in the United States and the Asia-Pacific region, which requires continuous service availability.

Choosing Clever Cloud was not driven by the pursuit of extreme performance, but by a precise balance:

• data hosting outside the scope of extraterritorial legislation,
• a genuinely European and independent company,
• a PaaS model that allows teams to focus on the application rather than infrastructure operations,
• and the ability to centralise the application, database and assets with a single provider.

For Badsender, Clever Cloud was selected not to “do more”, but to do things right, in line with both its values and operational constraints.

A pragmatic, prepared and well-supported PaaS migration

The migration to Clever Cloud was anticipated and prepared in advance. The main adjustments involved resource sizing and optimising performance for the specific needs of the application.

Despite the uncertainties inherent in any production deployment—particularly around real-world load—the support provided by the Clever Cloud team helped secure the transition.

The migration was completely transparent for LePatron users.

Centralisation, clarity and operational peace of mind

After several months in production, the benefits observed are primarily structural. Centralising the application, database and assets with a single provider has significantly simplified the team’s day-to-day operations. Logging and monitoring tools, available from the outset, proved more effective than previously used solutions.

Beyond the technical aspects, the human relationship also played a key role. Having direct access to identified contacts who understand the context of a small European organisation makes a tangible difference compared to large hyperscalers.

A technical choice that became a strong signal for the ecosystem

While end users did not experience any functional change, Badsender deliberately chose to communicate openly about the reasons behind this move: data sovereignty, environmental coherence, and alignment with an open-source vision of digital infrastructure.

This communication generated many positive responses from technical peers, partners and stakeholders within the email and responsible digital ecosystems. Choosing a sovereign cloud for web applications thus became a credibility signal, reinforcing the consistency between Badsender’s discourse and its actual practices.

Clever Cloud as an operational building block for sovereignty

For Badsender, Clever Cloud is neither a symbol nor an abstract promise. It is a concrete and coherent building block that makes it possible to apply principles often discussed only in theory: taking control of data hosting, remaining within a European legal framework, and focusing on what truly matters—the product and its use cases.

A pragmatic choice that allows the agency to keep moving forward: improving its products, supporting its clients, and continuing to challenge the practices of its industry.

Discover the testimonial of Eddy Montus, Co-Founder of Madietenligne

A fully in-house healthcare platform

Created during the pandemic, Madietenligne built and operated its entire platform internally from day one. This includes:

• video consultations,
• document sharing,
• patient record management,
• automated SMS and email reminders.

The architecture ran on self-managed bare-metal servers. As the platform grew, now used by more than 2,500 dietitians,  maintaining the infrastructure became increasingly demanding: zero-downtime deployments, server configuration, monitoring, version upgrades and data reversibility. Madietenligne needed to preserve its HDS compliance while reducing operational effort.

Compliance and simplification at the core

To support its growth, the platform needed to:

• maintain strict HDS-compliant hosting,
• ensure encryption at rest for database and file storage,
• guarantee 24/7 service continuity despite constant reminders being sent,
• reduce operational workload,
• rely on a sovereign infrastructure located in France.

Why Madietenligne chose Clever Cloud

In late 2023, Eddy Montus benchmarked several PaaS providers. The decision criteria were clear: performance, HDS, and French sovereignty. Clever Cloud met all three requirements, with a clear and transparent HDS contract.

Customer support also played a key role. Many technical questions emerged during the migration, all addressed promptly at the start of each day.

A fast migration with no noticeable downtime

The full migration, both test and production environments, took less than two weeks. It involved:

• transferring and synchronising 500 GB of documents,
• converting files previously stored on Azure,
• deploying PHP and Node applications via GitHub,
• managing CRON jobs and monitoring on the PaaS.

The DNS switch was the only potential interruption. For end-users, the transition was seamless.

Immediate benefits and full HDS continuity

By migrating to Clever Cloud, Madietenligne maintained its HDS compliance while significantly reducing its operational workload.

Key outcomes include:

• full continuity of HDS compliance, with encryption at rest enabled at database creation;
• simplified operations: no more NGINX configuration or fragile scripts;
• reliable, zero-downtime deployments, thanks to automatic swap and validation;
• responsive support, especially during migration;
• future-ready infrastructure, with autoscaling available if needed.

A sovereign and sustainable infrastructure to support future growth

With a sovereign, automated and easier-to-maintain HDS environment, Madietenligne can now focus on improving its product. The platform continues to grow in France and abroad, while maintaining a high level of security and regulatory compliance for health data.

Like many IT Services Companies, this firm specialised in placing tech experts, and internal IT had historically not been a priority. However, as the company grew and its operations became more complex, the need for transformation became unavoidable.

David embarked on a comprehensive modernisation, with a clear goal: streamline infrastructure, ensure business applications’ reliability, and optimise operating costs.

From overcomplication to rationalisation

Upon his arrival, David Caussinus made a stark assessment: the company was running a SaaS ERP, an Office 365 suite, and a digital factory hosting internal and client applications on AWS via Kubernetes (EKS). A complex and costly architecture for only 5–6 applications, while the internal IT team was very small and had limited expertise in managing such infrastructure.

Faced with these constraints, David initiated a paradigm shift. In January 2024, he decided to fully move away from AWS and Kubernetes, migrating everything to Clever Cloud.

Why Clever Cloud?

The ESN needed a simpler, more pragmatic infrastructure, aligned with available skills and business priorities.

Clever Cloud’s Platform as a Service solution allows teams to focus on applications, without worrying about operational maintenance.

A gradual, usage-oriented migration

Migration began with internal business applications essential to company operations: ERP data extraction, reporting, automations, and more.

These roughly ten applications included tools for extracting data from the SaaS ERP, processing data to feed Power BI reports, and various business automations.

In total, around ten applications were migrated. The digital factory developers regained a stable, responsive environment, tailored to their needs.

Lasting lessons

The experience reinforced David Caussinus’ strong belief: not all technologies suit every context, and a good technical choice is first and foremost one adapted to the situation.

To host this strategic platform, BLOOM chose Clever Cloud — a sovereign, secure, and automated hosting provider offering flexibility with minimal resources.

Trawl Watch: monitoring protected marine areas

Trawl Watch allows BLOOM to track more than 1,700 industrial fishing vessels across France and Europe, and to identify their presence in marine protected areas.

The tool enables BLOOM to:

• Collect alerts submitted by small-scale fishers;
• Request inspections from relevant authorities;
• Compile investigation files to pressure institutions;
• Inform the public about observed abuses.

A data-intensive application

Trawl Watch aggregates a wide range of data: real-time AIS trajectories, vessel speeds, ship types, time spent in sensitive zones…

All this information is displayed via an interactive map, filterable by area of interest, along with a dashboard showing metrics and rankings (e.g. most intrusive vessels, most impacted zones).

Clever Cloud manages the handling of AIS data volumes — often expensive and complex — while delivering constant performance and seamless scalability, without burdening BLOOM’s technical team.

PaaS hosting built for the mission

Clever Cloud addresses several critical needs for BLOOM:

• Frictionless scaling, crucial for handling a large real-time database;
• French infrastructure, protected from the Cloud Act and ensuring data sovereignty;
• A simple interface, making it easier for non-technical teams to work;
• Responsive support, throughout the project lifecycle;
• Active commitment, by providing cloud resources to power a project with high ecological impact.

Next steps: greater autonomy and impact

Upcoming features include:

• Automatic fishing detection, via open source models or a partner API;
• Smart alerting system, combining speed and time-in-zone to reduce false positives;
• Public launch, with a redesigned interface to boost accessibility and civic engagement.

To fulfil this mission, Data For Good relies on Clever Cloud — a fully automated PaaS infrastructure, hosted in France, that offers agility while ensuring data sovereignty.

A tech community committed to the common good

Since 2015, Data For Good has mobilised a community of volunteer developers, data scientists, and designers to work on high-impact projects. Each year, the organisation supports several NGOs and citizen-led groups through a structured tech incubation programme.

The projects span key issues like climate, social justice, and democratic transparency. All share the same ambition: to create useful and reusable digital commons, made open source for the benefit of all.

Why Clever Cloud?

The collaboration with Clever Cloud allows Data For Good to:

• Standardise technical practices on reliable infrastructure;
• Host sensitive tools securely, without sacrificing agility;
  Save time with a ready-to-use PaaS platform;
• Amplify the impact of the projects it supports.
  

Among the projects hosted on Clever Cloud:

• Trawl Watch: a platform to track industrial fishing vessels, co-developed with BLOOM Association;
  CodeCarbon: a tool that measures the energy consumption and carbon emissions of code execution, used in AI, data science, and software development contexts.

Technical focus on CodeCarbon

CodeCarbon was launched in 2019 at the Montréal Institute for Learning Algorithms (MILA). Incubated by Data For Good since 2021, the project benefited from Clever Cloud’s support to build a public API and a community database. This infrastructure helps centralise carbon impact data collected by the Python tracker integrated into users’ projects.

Clever Cloud hosts the API, database, and visualisation app, which went live in December 2023. It allows organisations to monitor their workloads’ carbon footprint, with metrics broken down by task, hardware, duration, and energy use.

The project relies on:

• Low-level metrics collection (GPU via NVIDIA SMI / AMD ROCm, CPU, and RAM);
• Heuristics fallback, when direct access is limited, ensuring compatibility across cloud environments;
• Integration of national energy mixes, using Electricity Map data to calculate localised carbon impact.
  

From build to run, without friction

Thanks to Clever Cloud’s PaaS approach, incubated projects can scale to production quickly, with automated, reliable run environments, and no operational overhead. This continuity allows associations to focus on their missions while keeping tools fully operational.

A shared vision for responsible tech

At Data For Good, every line of code is written to build a fairer future. With the support of a reliable, sovereign French cloud provider, the organisation can focus on what matters: bringing impactful digital solutions to life.

What sets it apart? The agency has developed its own in-house CMS, enabling it to offer its customers faster, more personalised and customised website design.

Faced with the growing challenges of high availability and scalability, the agency decided to migrate to Clever Cloud to guarantee its customers a professional, high-quality service.

Read what Maxime Magné, Co-founder of Évolusite, has to say about his experience

A proprietary CMS for efficiency

Évolusite stands out for its unique approach: the agency has developed its own in-house CMS for website creation. This solution makes it possible to create sites more quickly and entirely customised to each customer's needs.

Evolusite's CMS offers customers a simplified and intuitive administration interface, giving them access to all the essential information: site statistics, number of views, most frequently consulted pages, types of device used by visitors, content management, lists of projects, products for e-commerce, and orders.

The aim is clear: to relieve customers of the technical management of their website so that they can concentrate on their core business, while benefiting from personalised, responsive support.

The challenges of rapid growth

For two years, Évolusite was hosted on a conventional server. This solution, which was the natural choice at the start, quickly showed its limitations as the agency grew.

Why choose Clever Cloud?

The search for a more robust solution naturally led Évolusite to Clever Cloud. The decisive criteria were:

• High availability: guaranteed uninterrupted service;
• Native scalability: automatic horizontal and vertical scalability according to needs;
• Advanced monitoring: easy access to logs and performance monitoring;
• Simplified database management: migrations in just a few clicks, with no downtime;
• Automated back-ups: 7-day back-ups to ensure data security;
• Responsive support: assistance and quick answers to questions.

Une migration préparée avec soin

Migration to Clever Cloud required considerable technical preparation. The Évolusite application, initially developed for traditional hosting, had to be adapted to take full advantage of the scalability capabilities of PaaS.

Once the development work was complete, the actual migration went remarkably smoothly. In less than twenty minutes, the entire system was up and running on Clever Cloud, including the complete migration of the database.

A solid technological partnership

For Évolusite, Clever Cloud is much more than just a hosting provider: it's a technology partner that allows the agency to focus on its core business while offering its customers a professional, high-quality service.

Thanks to this robust, scalable infrastructure, Évolusite can now support its customers' growth with complete peace of mind, with the guarantee of a permanently available service and optimised performance.

Supported by the CaPASSCité association, in collaboration with addictologist Dr. Géraldine Talbot, Option Zéro has been developed by Selego. Also supported by the Fonds de lutte contre les addictions, the application offers personalized follow-up and genuine support in managing addictions.

Option Zéro processes sensitive health-related data. For Selego, user confidentiality is an absolute priority. The team therefore wanted to comply with the highest standards attested by the Health Data Hosting certification, covering the six activities set out in the standard.

Why Clever Cloud?

Several criteria guided their choice:

• HDS compliance: Health Data Hosting certification was essential to guarantee the security and compliance of the hosting.
• Sovereignty: the infrastructure had to be hosted in France.
• Simplicity and automation: need for a modern PaaS solution, with managed resources and rapid learning curve.
• Customer support: available and responsive.
• Time savings: a platform that lets you quickly host your application in a secure environment, without having to configure everything yourself. Updates can be deployed easily, and the management of different environments is uncomplicated.

Another key point was the ability to easily control scalability via the console. When it went live, Option Zéro quickly reached several hundred daily active users, without encountering any performance problems - with a single instance of 4 CPUs and 4 GiB of RAM.

Support to match

"We appreciated the quality of the support offered by Clever Cloud, enabling us to benefit from a competitive offering, a sovereign cloud, and easy to get to grips with. They're a reliable partner, who understands the regulatory constraints and technical challenges of a project like ours."

An obvious choice

For Selego, Clever Cloud was an obvious choice when compared with other solutions:

"We considered a number of different providers, but none of them offered the same level of service as Clever Cloud. With its self-service solution, Clever Cloud limits the costs associated with infrastructure administration, while offering fully managed machines that are already ready to deploy."

Une solution SaaA SaaS solution for e-reputationS au service de la e-réputation

Guest Suite is a SaaS solution provider that helps businesses with at least one physical location manage their online reputation and local visibility. With a comprehensive approach, the platform supports the entire customer review lifecycle — from collection and distribution to analysis, response, and centralization — as well as the online presence of a business location. Unlike some review platforms, Guest Suite operates in the background, allowing its clients to take the spotlight by showcasing their reviews and boosting their visibility on major platforms like Google Business Profile, Pages Jaunes, and Tripadvisor.

The multi-sector solution is aimed at all professionals for whom online reputation has a direct impact on the act of buying or booking.

A major technological overhaul

Two years ago, Guest Suite launched a major overhaul of its platform, which at the time had 9 years of continuous development behind it. This new version was designed to meet the challenges of scalability and performance, as well as simplifying technical workflows.

The objective was clear: to regain control of the entire product and its infrastructure, with a gradual ramp-up of the teams, while integrating simpler, more reliable tools that consume less human resources on the hosting side.

Why choose Clever Cloud?

Faced with the considerable legacy of its IaaS infrastructure, Guest Suite decided to rely on Clever Cloud's PaaS to support its new SaaS platform.

There were a number of reasons for this choice:

• Greater peace of mind: Clever Cloud takes charge of managing the infrastructure, backups, deployments and monitoring;
• Native scalability: essential to support the rapid growth of users on the new platform;
• Sovereign and French hosting: a prerequisite increasingly demanded by major accounts;
• Technical and human proximity: with personalised, responsive and fluid support throughout the migration phase;
• Greater autonomy for developers: well-organised environments, accessible variables, automatic redeployments in the event of failure.

A rapid and controlled migration

The migration to Clever Cloud took place in less than two months, between March and April 2024. Each application was migrated independently, under the responsibility of the technical leads. Careful support from Clever Cloud enabled the differences between IaaS and PaaS to be overcome quickly.

Tangible benefits within the first few weeks

By relying on Clever Cloud, Guest Suite saw a number of immediate improvements:

• Automated, reliable deployment: in the event of a crash, automatic redeployment takes over;
• Improved management of backups: everything is automated, secure and compliant with ISO 27001 and 9001 standards;
• Newfound flexibility: rapid creation of SQL instances and use of environment variables in the interface facilitate testing and experimentation;
• Simplified onboarding of new developers: the runtimes are standardised and it takes no time to get to grips with the system.

An infrastructure ready for the future

Today, more than half of Guest Suite's customers are already using the new platform hosted on Clever Cloud. The full migration will soon be complete. Thanks to solid, sovereign and scalable PaaS hosting, the teams can concentrate on what really matters: enriching their product and helping their customers to control their online image.
