Overview

Since the Industrial Revolution, energy companies have continuously evolved in response to new opportunities, challenges, and questions, such as: how can we take advantage of renewable-energy sources and provide sustainable-energy options to customers? Many energy providers are looking to technology and digitalization to drive insights into energy use and to provide consumers and companies around the world with continuously optimized renewable-energy options.

As a leading global provider of power and energy-efficient services, ENGIE's mission is to not only provide power through low-carbon, renewable resources but also to be a leading innovator in the space through technology. “From utility and energy services to production to distribution to sales, we focus on the big picture and strive to be a leader in the energy-decarbonization transition,” says Thierry Langer, chief information officer (CIO) of the finance division at ENGIE.

“Our CEO, Isabelle Kocher, has defined a new strategy for ENGIE focused on decarbonization, digitalization, and decentralization. This transformation strategy has placed a much greater emphasis on data and operational efficiency,” explains Langer. “We're at an important step in the development of the Group; in order to be more precise in our calculations and performance measurements, we must develop better and more consistent tools and capabilities across business units.”

Measuring business performance became a top priority—and challenge—for the finance division, particularly given the variable cost of utilities.

Opportunity | Simplifying Financial Processes to Produce Precise and Consistent Insights Across Business Units

To address these issues, ENGIE created its Common Finance Program (CFP), which integrated different enterprise-resource planning (ERP) systems used by various companies within the Group worldwide. The company created a centralized finance system and business framework to simplify processes while creating consistency across the Group. "It’s imperative for the finance division to have dependable capabilities to measure our costs and performance consistently across divisions," says Langer. "But we have a varying portfolio and each company calculates costs its own way, so it can be difficult to measure and compare data accurately between two companies at a Group level.”

By developing a new solution that integrates with local ERP systems and transforms localized data into a standardized central business framework in the same instance, ENGIE hoped to provide more precise data measurement and analysis for both local and central users.

“We sought to transform our financial processes through the CFP and we believed that the tools that would enable this transformation begin with SAP—specifically SAP HANA,” explains Langer.

Solution | Beginning with SAP HANA On Premises and Migrating to S/4HANA on AWS

Because of SAP’s position as a leader in the ERP market and broad adoption by enterprises worldwide, ENGIE chose to use SAP tooling widely throughout the Group. For the finance team, SAP was a critical component in successfully transforming its processes and fulfilling the mission of the CFP. The finance team first chose to run its SAP Business Suite on HANA implementation on premises. However, as the team began to evaluate its long-term approach and goals—which included an upgrade to SAP S/4HANA— it began to re-evaluate its hosting situation.

“Two of the most critical factors for the CFP when we evaluated the development of our system and upgraded our SAP deployment to S/4HANA were time and scalability,” Langer explains. “We needed to update our platform while at the same time developing a new analytics solution and new business model. Moreover, each local ERP system needed to connect to S/4HANA for development. During the short development timeframe, we needed to scale substantially—which made AWS a compelling option for us.”

ENGIE had already engaged with AWS as it underwent a broader organizational digital transformation. The finance team felt that, given the company’s experience as well as the proven AWS technical capabilities for running large-scale SAP workloads, AWS would be an excellent partner to host the development environment for the CFP.

Thierry Langer and his team engaged AWS Professional Services and began building a business case for migrating the CFP’s development environment to AWS.

“48 hours after the AWS team provided a comprehensive demonstration of what was possible on AWS, we decided to migrate our non-production environment to AWS. After we completed that step, we chose to migrate our entire platform and production environment as well,” says Langer. “I saw the difference between running SAP on premises and on AWS, and there was no question it would be advantageous for us to migrate to AWS.”

From initial decision-making to the go-live date, the project took approximately six months. This aggressive timeline was much shorter than Langer had expected or experienced with past projects of a similar scale (which took between nine and 12 months). “I was quite impressed by the delivery timeframe for a completely new and complex SAP platform,” says Langer. “The rollout was very smooth. I found myself wondering if we really had gone live. With this kind of upgrade, it had become normal for us to expect some errors and difficulties, but it wasn’t like that with AWS. I was perplexed, and pleasantly so.”

AWS X1 Instances Power ENGIE’s SAP S/4HANA Database

The ENGIE finance team worked closely with AWS Professional Services during every step of the engagement with AWS and found the AWS Enterprise Support team valuable. “Our experience working with AWS Professional Services and AWS Enterprise Support has been excellent,” says Langer. “AWS Professional Services were instrumental in the project and have helped transfer their expertise to our internal team so we can work towards being fully autonomous while we run the platform.”

At the core of ENGIE’s SAP deployment on AWS is the Amazon Elastic Compute Cloud (Amazon EC2) X1e instance, which is designed for running high-performance databases and in-memory workloads like SAP HANA. X1e instances are powered by four Intel Xeon E7 8880 v3 processors, offering up to 128 vCPUs and 3,904 GiB of DRAM-based memory.

The AWS Professional Services team worked with ENGIE to automate a lot of the SAP environment, including the SAP database, by using AWS CloudFormation. Currently, ENGIE is running several SAP solutions on AWS, including SAP S/4HANA, SAP S/4HANA solution for Central Finance, SAP Fiori User Experience (UX), SAP Adobe Document Services (ADS), and SAP Content Server.

Outcome | Saving Time, Simplifying Processes, and Improving Insights Running SAP S/4HANA on AWS

For the ENGIE finance team, being able to reduce the expected delivery time of its new business framework by two times while upgrading its SAP platform to SAP S/4HANA was immensely beneficial for driving new business outcomes and opportunities.

"Deciding to migrate our SAP footprint to AWS while developing our new business framework and analytics system proved to be an excellent choice for us," says Langer. “We were able to reduce the footprint of our database substantially: on premises, our SAP database was 4 TB on the primary database and 4 TB on the secondary database. By moving to AWS, we right-sized our database. We reduced the size of the primary database from 4 TB to 2 TB and reduced the secondary database from 4 TB to around 200 GB.” ENGIE has not only saved costs by reducing the size of its HANA databases, the company also achieved cost savings by avoiding the need to procure on-premises hardware on an ongoing basis.

“We’ve increased data transparency for our business organizations with continuous financial reporting,” says Langer. “We also drastically reduced the ramp-up time for new users from three days to one day by running SAP S/4HANA on AWS.”

ENGIE continues to engage with AWS to optimize its environment and introduce innovation to its platform. For example, the AWS Professional Services team is currently working with ENGIE to build a custom auto-scaling solution for the SAP application using AWS Lambda, Amazon Athena, and Amazon DynamoDB.

"Currently, our team is the only team within ENGIE running S/4HANA. As the first company use case for running S/4HANA on AWS, we've demonstrated what's possible," says Langer. "As we continue to focus on digitalization and driving insights through data, we feel it is an enormous advantage to be running S/4HANA on AWS."
