The Real Role of AI in Mainframe Modernization Is Still Being Misunderstood
The discussion around artificial intelligence in the mainframe usually starts in the wrong place. People talk about code generation, automatic translation, and copilots. All of that matters, but it does not solve the core problem: no one can fully understand everything that is already running.
Eccox at FEBRABAN TECH 2026: an immersion in technology, innovation, and new perspectives
From August 24 to 26, the Eccox team was present at FEBRABAN TECH 2026, closely following the discussions, trends, and experiences that marked another edition of the largest technology and innovation event in the financial sector.
Mainframe Talent Shortage: Why the Problem Is the Environment, Not the People
The market often treats the shortage of mainframe professionals as an unavoidable problem. A natural consequence of an “old” technology that is difficult to learn and disconnected from younger generations. That interpretation is convenient and, in most cases, wrong.
The problem is not a lack of interest. It is the experience.
Emulated Tests vs. Real Tests: Why Emulation Fails Where Risk Is Highest
Mainframe modernization rarely fails because of a lack of technology, but because of too many assumptions. In mission-critical environments, it is not enough to validate whether something works. You need to ensure that it will continue to work under real load, with real data, and real dependencies.
This is where the difference between emulated testing and real testing stops being a technical matter and becomes a direct decision about operational risk.
Much More Than a Gathering: Cultura Eccoxer Celebrates the People Who Bring Eccox to Life
On **August 10**, Eccox brought its employees together for an afternoon dedicated to what lies at the heart of its journey: **the people, culture and relationships that help build the company every day**.
Held at **Grupo Acelerador – Sala São Paulo, in Alphaville**, **Cultura Eccoxer** was created to bring employees together, strengthen connections and celebrate the history built over the years.
José Ronaldo Martins: The Founder Who Never Stopped Being a Student
Those who know him tend to immediately associate him with mainframes, COBOL, @Eccox products, or the technical discussions that have spanned decades of enterprise computing evolution.
But the trait that defines him best is something else. Ronaldo never stopped being a student.
6-Month ROI: Why Mainframe Modernization Starts with Testing (Not Code)
Mainframe modernization is often perceived as a long-term initiative with delayed returns and significant risk. For CFOs and CTOs, this has created a common perception: modernization is necessary, but the financial impact takes too long to materialize.
The problem is that this assumption starts from the wrong place. The biggest cost is not the transformation itself—it is the development lifecycle that supports it.
The Culture of Those Who Keep the Invisible Running
Most people will never think about what happens between sending a Pix payment and having it received—and that’s precisely the point. Some technologies are built to be seen, while others exist to ensure the world never stops.
The mainframe has always belonged to the second group. It doesn’t appear in social media feeds, become a trend, or dominate conversations about “the future of technology.”
Batch Window Optimization and Code Quality: How to Sustain 24/7 Operations Without Sacrificing Mainframe Efficiency
For years, mainframe operations were built around a simple premise: daytime was for processing, nighttime was for consolidation. The batch window was when systems closed transactions, reconciled data, and reorganized workloads. That model worked—until transaction volumes stopped following the clock.
Today, with Pix, Open Finance, and applications available 24/7, processing never slows down. It keeps growing while the batch window continues to shrink.
