9OCTOBER 2025The initial expectation that cloud would be the ultimate solution for all IT challenges has been replaced by a more balanced approach, recognizing the limitations and hidden costs of a purely cloud modelmost of its infrastructure in its own data centers, despite the growing use of public cloud in the financial sector.At the same time, there has been an evolution in data centers. Today, tools and platforms simplify and automate infrastructure delivery. Private clouds have significantly advanced, along with new consumption-based contract models (As a Service). It's already possible to achieve better costs with private clouds, even when compared to workloads deemed efficient in the public cloud, such as containerized and auto-scalable applications.That initial vision of the cloud absorbing all types of services has been replaced by a hybrid strategy, where the benefits of an on-premises structure coexist with what really makes sense to be in the cloud, after all, cost is only one of the pillars that should guide this decision.On the other hand, when it comes to innovative and specialized technologies, such as Artificial Intelligence (AI) and Analytics, it makes more sense to use ready-made services available in the cloud, rather than investing time and money in acquiring and implementing disruptive or specialized technologies internally.The trick lies in keeping in-house the systems that do not fully benefit from the cloud, such as consolidated applications with predictable growth, while ensuring agility in meeting business demands. At the same time, the cloud should be leveraged for innovative and highly scalable services, designed to thrive in that environment.However, managing a data center requires attention to several aspects ­ availability, resilience, capacity, scalability, accessibility, speed, efficiency and risk. In the cloud, most of these issues come "packaged." For companies with a mature and evolving structure, the transition to a hybrid model or the repatriation of workloads is a less painful process. On the other hand, for organizations whose infrastructure limitations prompted the migration to the cloud, or that were born in the cloud, this journey can be much more complex.Some factors are crucial in this journey, such as the adoption of open technologies, instead of proprietary solutions that may lock the company into a single provider. Ideally, applications should be agnostic, capable of operating both in private and public clouds, with scalability between them in some specific cases.Infrastructure and Platform are becoming commodities, even the container orchestration layer is becoming a market standard and some data center providers have realized they can compete at this level, offering these types of service. In the coming years, the real competitive edge will come from offering specialized products, such as specialized services in AI or ML, Big Data, IoT, E-mail and collaboration and platforms like SAP or Salesforce, regardless of the cloud provider behind the solution.At a time when cloud dominates infrastructure discussions, it has become clear that not all workloads benefit equally from this model. The initial expectation that cloud would be the ultimate solution for all IT challenges has been replaced by a more balanced approach, recognizing the limitations and hidden costs of a purely cloud model. Workload repatriation is a response to this reality, driven by the pursuit of greater cost control and operational efficiency.Hybrid StrategiesA well-planned hybrid strategy emerges as the ideal solution. It allows companies to internally manage predictable and consolidated workloads, while leveraging the agility and scalability of the cloud for innovations and highly dynamic demands. For organizations that have achieved sufficient maturity in their infrastructures, the combination of public and private cloud can ensure the best of both worlds: efficiency, agility and innovation. In the end, the secret is not in choosing between data center or cloud, but in finding the right balance between both, based on the specific needs of the business.
