What is a Mainframe?


The mainframe is the powerful computing heart of many organizations, designed to process large amounts of data and transactions. These "giants" of the IT world are used in sectors like finance, healthcare, retail, and other critical industries where reliability and security are crucial. Modern Mainframe, like the IBM z16 system, is no longer the size of a living room, but it still provides unmatched reliability, security, and performance compared to other hardware and software platforms.

Despite the long-term presence of Mainframe in large systems, there is a misconception that these systems are obsolete, but the truth is actually quite the opposite. Mainframe-based systems have continued to evolve, adapting to modern technologies such as artificial intelligence and cloud computing.

A few interesting facts that you might not know:

  • 90% of all global transactions are processed on the mainframe.
  • Mainframe supports 68% of global data processing.
  • 71% of Fortune 500 companies use mainframe.
  • 92 of the world's 100 largest banks, as well as all 10 largest insurance companies, rely on mainframe.
  •  Mainframe can survive an earthquake of 8.0 on the Richter scale. :)

Why is Mainframe Important?


A mainframe isn't just a computer for large corporations—it's a platform that powers the global economy.
Its security, speed, and resilience make it indispensable, especially in today's world where cyber threats are on the rise.

  • BankingIf you've withdrawn money from an ATM today, a mainframe likely processed your transaction.
  • RetailIf you've made an online purchase, a mainframe probably handled your transaction.
  • GovernmentTax, pension, and other government systems worldwide are powered by mainframe platforms.

Safety Iron Man


In today's digital environment, where every click can represent a threat, the mainframe stands out as an armored hero. Financial institutions, hospitals, and governments rely on it for its impenetrable security. Fun fact: it is not possible to make a virus or malware for the mainframe, and so far no one has been able to hack it :)

By providing robust systems for security audits and traffic analytics, modern Mainframe systems enable quick vulnerability identification. Integration with hybrid cloud solutions further enhances security through a distributed approach, while continuous updates to security measures ensure adaptation to new threats in cyberspace.

Mainframe for the Next Generation


Who says Mainframe is only for older generations? Thanks to tools such as Docker, Kubernetes, or Ansible, young developers can use familiar technologies on this platform. With the addition of languages like Python, Mainframe becomes a playground for innovation – ranging from blockchain solutions to advanced analytics systems.

Imagine a system that can predict and resolve issues before you even notice them. With artificial intelligence, the mainframe becomes not just reliable, but an intelligent business partner. Automating routine tasks, such as backing up and optimizing resources, frees up your time and energy for creative projects.

Career opportunities for those who dare


The mainframe is like a hidden golden ticket for your career. While everyone is chasing the latest trends, mainframe experts are becoming rare – and, therefore, extremely in demand. Learning COBOL, JCL, or modern DevOps tools can be a ticket to a career in a field that offers security, stability, and challenges.

Mainframe technology is an excellent choice for students because there aren't many experts in this field in the labor market, meaning there's less competition and more job opportunities. Investing time in learning about mainframe systems allows you to build a specialized skill set that is in high demand among enterprise clients.

Mainframe is cool


Kao što je to bilo i do današnjeg dana, Mainframe će i u budućnosti iznova dokazivati zašto je nezaobilazan dio budućih tehnoloških trendova. Spojem tradicionalne snage i moderne inovacije, Mainframe postaje platforma za sve - od globalnih transakcija do kreativnih tehnoloških rješenja.
