Datanumia is migrating its energy monitoring platform to the AWS cloud

Datanumia, Leader in Energy Data Valorization

Datanumia is a software publisher specializing in the valorization of energy data. Formed from the merger of two EDF subsidiaries in 2021 — Netseenergy and Edelia — it develops innovative digital solutions (web portals, apps) to help individuals and businesses monitor and optimize their energy consumption and carbon footprint.

Using advanced techniques combining statistical modeling and predictive analytics, Datanumia helps both individuals and professionals understand and leverage their data to guide them toward energy efficiency.

With over 10 million data points processed daily, Datanumia controls the entire data value chain, ensuring the highest quality, security, and protection of the collected and reported data.

Creation of a Unified IT Department Leading to Cloud Migration

The merger of EDF’s two entities in January 2021, which gave birth to Datanumia, led to the creation of a unified IT department. At this point, one of the entities (Netseenergy) operated on AWS infrastructure, while the other (Edelia) relied on on-premise data centers.

Security and GDPR Compliance Challenges

Due to significant obsolescence risks in data centers and the need for full control over the technical stack and business operations, a cloud migration quickly became essential to ensure platform security and service continuity.

The goal was to transition more than 13 million users of Datanumia’s energy monitoring platform while placing security at the heart of the project to guarantee the protection of personal data:

• Data Protection and Security: Storing data in France and encrypting data both at rest and in transit.
• Governance and Access Management: Centralized role management and applying the principle of least privilege.
• Monitoring, Auditing, and Operations: Centralized security mechanisms with real-time monitoring and detection of malicious activities.
• Network Security: Implementation of a transit zone and various flow filtering mechanisms.

To achieve this, Datanumia called on Onepoint’s expertise to support its cloud migration process to AWS.

Key Success Factors of the Migration to AWS Cloud

Onepoint provided its expertise to cover the broad technological framework surrounding the AWS infrastructure: all services… and more, including expertise in OKD/OpenShift deployment on AWS.

Thus, Onepoint proposed a streamlined approach with senior experts whose complementary skills allowed them to capitalize on:

• Their relevant operational knowledge and experience in line with project expectations
• Their mastery of the application modernization process

To meet the project’s challenges and needs, Onepoint adopted a comprehensive, methodical, and multi-phase approach, within an agile framework with a DevOps mindset, full IaC, and end-to-end management.

A Project Conducted in Four Phases:

1. Framing: End of 2021 – Study and collection of requirements, inventory, and assessment of the existing ecosystem, cost estimation, and macro-planning.

2. Preparation Phase: Architecture proposal, notably through the construction of the AWS landing zone: all infrastructure services required to host the consumption tracking platform and adapt deployment scripts.

In terms of security, the implementation of encryption — using KMS and keys managed by Datanumia (Bring Your Own Key) — allows full control over data access.

This landing zone also facilitates future developments of Datanumia’s applications and products, as well as the sharing of technical elements between the B2B and B2C platforms resulting from the companies’ merger.

3. Deployment of “Up & Running” Environments: A rapid, automated, and iterative implementation of the different qualification and production environments, including a deployment phase and a full suite of end-to-end tests: TNR, Business Acceptance, and performance benchmarking, all involving the Datanumia x Onepoint project team to co-build Up & Running environments.

Throughout the project, Datanumia maintained a close and transparent relationship with its clients, keeping them informed of progress and any ongoing or upcoming infrastructure changes.

4. “Up to Date” Technical Architecture Documentation: A modern, high-performance, resilient, redundant, scalable-by-design, and natively secure architecture to ensure compliance with Datanumia’s security and GDPR requirements, as well as AWS architecture patterns.

An Agile Full DevOps Approach: Throughout the project, Onepoint committed to delivering infrastructure LZ and various environments iteratively in a full Infrastructure as Code (IaC) approach. For each delivery: Acceptance sessions were scheduled with Datanumia teams.

End-to-End Cross-Functional Management:

• Participation in Datanumia’s PI Planning and breaking down user stories into sprints according to the project timeline.
• Daily coordination and alignment with Datanumia team leads and Onepoint team (daily meetings).
• Detailed Management:
• Weekly steering committee with all stakeholders to closely monitor progress and mitigate any blocking points.

Continuous “Up-to-Date” Architecture Documentation: Throughout the project and its various phases, Onepoint continuously delivered technical architecture documentation, covering all possible views: HLD (High-Level Design) and LLD (Low-Level Design).

A Migration that Strengthens Service Quality

The migration allowed Datanumia to address the obsolescence issues identified in the data centers, while also supporting the increased usage of its platform.

Indeed, the energy crisis and rising energy prices observed in 2022 led to a significant surge in demand for Datanumia’s services. An additional 800,000 individuals subscribed to the platform, representing a 7% increase compared to 2021. This trend accelerated, particularly with the arrival of winter, seeing a 96% increase in subscriptions in October and an 86% increase in November compared to the previous month.

The rapid implementation of the migration enabled Datanumia to respond quickly, ensuring it could meet its clients’ needs during an unprecedented and unforeseeable situation. As a result, service quality was maintained, allowing Datanumia to continue supporting its clients in their journey toward energy efficiency.

Ongoing Evolutions

Building on its partnership with Onepoint, Datanumia continues to maximize the value of its cloud migration.

In addition to transitioning to replatforming, Datanumia is refining its practices to optimize costs in response to the growing client demand.

The next step is to fully leverage the flexibility offered by AWS, taking advantage of AWS’s auto-scaling capabilities to adjust cloud usage in real-time based on the platform’s client needs.

Gradually, Datanumia will evolve by implementing managed services and serverless technologies, allowing it to reduce efforts spent on maintaining physical infrastructures and focus more on its expertise in data processing related to energy and sustainability.
