Aelis Case Study: Secure Housing and Connectivity for Sage ERPs in the Cloud
The partnership that ensures service continuity, security, and scalability for SMEs
The Challenge
Aelis needed to consolidate its IT infrastructure into a dedicated private cloud environment, hosted in external data centers, to deliver more secure, agile, and scalable Sage ERP solutions to its clients. Keeping servers distributed across client premises created high operational complexity, hindered standardization, and increased risks to service continuity. The challenge was to centralize all environments in its private cloud, ensuring a seamless migration of critical systems and fully secure data management.
The Solution
Adam provided rack colocation, dedicated connectivity, and comprehensive technical support, managing a progressive migration of servers to the data center while ensuring continuous uptime throughout the process. The infrastructure was replicated between Madrid and Barcelona, combining physical and logical security, power redundancy, and scalability to support Aelis’s growth and its clients’ diverse requirements.
Founded in 2005, Aelis was created with the mission of bringing advanced technology solutions to small and medium-sized enterprises (SMEs)—a segment that, at the time, lagged behind large corporations in terms of digitalization. Today, the company has nearly 200 employees and over 2,000 clients across multiple industries, with annual revenue approaching 20 million euros.
Aelis focuses primarily on the implementation of Sage ERP solutions, being one of the main Sage partners in Spain, as well as on developing vertical applications tailored to specific industries such as food production and waste management.
In addition to ERP implementation, Aelis provides comprehensive support and custom software development, ensuring that each client can optimize their processes and adapt efficiently and securely to digital transformation.
20 Years Digitalizing SMEs with Sage ERP Solutions
Since its founding in 2005, Aelis has remained committed to helping Spanish SMEs digitize their processes and leverage technology to enhance management efficiency. Two decades later, the company stands as one of Sage’s leading partners in Spain, with nearly 200 professionals, more than 2,000 active clients, and close to 20 million euros in annual revenue.
Aelis structures its activity around three complementary areas: implementing Sage ERP solutions; providing end-to-end system and server management—hosted in Adam’s data centers—which enables SMEs to outsource their IT infrastructure; and developing custom applications that adapt standard products to each client’s unique needs, creating truly tailor-made solutions.
What began as on-premises server deployments in client offices has evolved into advanced ERP environments fully hosted in Adam’s cloud, allowing businesses to work efficiently and securely from anywhere in the world.
Personalized support and hands-on guidance remain essential for companies that, due to their size, lack in-house IT departments—from implementation and training to ongoing support and custom tool development that complements standard Sage systems.
Aelis also stands out for its sector-specific expertise, developing vertical solutions for industries with complex, specialized needs, such as food traceability or waste management. This blend of technical know-how, strategic vision, and close client relationships has positioned Aelis as a benchmark in SME digital transformation—while keeping its original mission intact.
“Our mission remains the same as it was at the beginning: to help SMEs adapt to new technologies and achieve the highest level of digitalization.”

Migrating ERP to the Cloud While Ensuring Service Continuity
With a large base of ERP deployments in on-prem environments and highly diverse client requirements—ranging from factories to accounting firms—Aelis was looking for a partner to help consolidate and scale its own cloud platform, enabling a smooth and secure migration from clients’ local servers to a centralized infrastructure. The goal was to unify its data centers without disrupting daily operations or compromising the performance of critical systems.
In Adam, Aelis found the perfect match: a robust and scalable infrastructure combined with close technical collaboration, fully aligned with Aelis’s DNA. Thanks to this partnership, Aelis now hosts its private cloud across Adam’s data centers in Madrid and Barcelona, with mirrored servers that ensure high availability, service continuity, and full redundancy.
“What made us decide to move all our infrastructure and grow with Adam was their balance—a very solid scale and data centers in different locations, allowing us to replicate servers between Madrid and Barcelona.”

“One of the things we like most about Adam is that their way of working closely matches ours.”

A Collaboration Built on Proximity and Flexibility
In this partnership, Aelis particularly valued Adam’s flexibility and close technical approach, which made it possible to tailor each solution to clients’ specific requirements. This collaborative mindset enabled a “silent” migration to the cloud—with complete security and no perceptible downtime for end users.
Thanks to this alliance, Aelis has consolidated its entire infrastructure within a scalable, certified environment, managing over 100 TB of storage and thousands of concurrent ERP users accessing remotely. Replication between data centers, advanced backup policies, and rapid response during emergencies—such as the nationwide outage in April 2025—have reinforced Aelis’s trust in Adam, ensuring data protection and continuous operation at all times.
“We have great peace of mind knowing that all our clients hosted at Adam are covered. Even in the face of serious incidents, everything keeps running, and there’s an immediate recovery plan. That gives confidence to us—and to our clients.”
Carlos Calvo, CIO of Aelis
The Result: A Secure, Scalable, and Efficient Solution
For Aelis, one of the most valuable outcomes of its collaboration with Adam has been the simplicity achieved both commercially and technically: having a single point of contact and a unified workflow that optimizes processes, reduces management time, and enables a faster response to client needs. This centralization has significantly improved internal coordination and the overall quality of service.
From a technical perspective, infrastructure scalability has been key, as Aelis’s clients demand flexible solutions that can grow alongside their businesses. To meet that demand, both Aelis and its technology partners must be able to scale seamlessly together—something Adam’s infrastructure has proven fully capable of supporting.
The decision to migrate all infrastructure to Adam’s data centers was driven by this need for expansion and adaptability. Aelis found in Adam an environment that not only guarantees security and business continuity but also allows solution customization without technical limitations or connectivity restrictions—issues they had faced with other providers.
As a result, Aelis now delivers a robust, well-balanced solution that meets the needs of both large companies and SMEs alike. The combination of security, flexibility, and scalability has become the foundation of its value proposition.
“Working easily with Adam, without the excessive rigidity we had with other providers, is what has kept us together for so many years.”
Eduardo Vía, CEO of Aelis
“We’re very happy with this relationship, and I believe the human touch behind Adam’s technological solutions is their true differentiator.”

The Future: A Strategic Partnership and Shared Growth
As this case demonstrates, the relationship between Aelis and Adam has been built on technical trust, operational simplicity, and the ability to grow in sync. In a market where demand for cloud solutions is rapidly increasing, having a partner capable of supporting that growth with agility and reliability is essential.
Through its collaboration with Adam, Aelis has scaled its infrastructure effortlessly, adding capacity with ease while maintaining service continuity. With close, hands-on management—both commercially and technically—the Aelis team can focus on growing its business, confident that its housing and connectivity environment is in good hands.
This stability enables both companies to continue building a long-term relationship founded on trust and a shared vision of secure, efficient, and sustainable growth.
“Contacting support usually means something’s wrong—and in our case, it’s rarely been necessary. That shows everything works as it should.”
