8CIOReview | | OCTOBER 2024Historically, data centers were considered reactive, slow, and inefficient. The rise of cloud services changed this reality, enabling companies to meet their business demands with greater agility. Consequently, most rushed in this direction, attracted by promises of ease, speed, and efficiency.However, over time, it became clear that not every workload is efficient in the cloud. "Repatriation" movements emerged, as demonstrated by the 2024 Barclays CIO survey, published by Michael Dell on his LinkedIn profile, where 83% of companies plan to move workloads back to their private clouds. But why is this happening?The transition to the cloud is not always optimized. The "lift and shift" approach, inaccurate cost control, inadequate sizing choices, and the unpredictability of data growth can create significant issues, particularly in terms of cost. Public cases support these statements, such as Dropbox in 2016, which realized it would be more economical, in the long run, to build and operate its own data centers, or Bank of America, which decided to keep most of its infrastructure in its own data centers, despite the growing use of public cloud in the financial sector.IN MY OPINIONBy Cléber Alexandre Agazzi, Head of Infrastructure & IT Operations, SicrediIN TIMES OF CLOUD, WHY USE A DATA CENTER?Cloud migration has transformed the way companies manage their operations, promising greater agility, scalability and cost reduction.

While some applications thrive in this environment, others have shown significant challenges, leading many organizations to rethink their strategiesCléber Alexandre Agazzi
