Eliminating instability to unify healthcare operations
For more than 30 years, Micromed has been a reference in cardiology diagnostics in Brazil. What began with locally made ECG equipment has grown into a portfolio of cardiology devices and a new generation of digital platforms. But as the company expanded, its infrastructure created challenges that slowed operations and limited growth.
The company’s ERP system was still hosted in a monolithic structure that frequently disrupted day-to-day work. “Previously, our ERP system operated in a separate environment with a rigid architecture that caused slowness and instability, especially during critical periods like monthly financial closing. This directly impacted our billing and accounting reconciliation,” says Felipe Broering, chief technology officer.
The instability created bottlenecks in basic tasks such as invoicing, payroll, and integration with Micromed’s digital platform. These issues drained engineering resources and prevented the company from moving quickly to meet growing demand. To scale effectively, Micromed needed a unified and reliable foundation for both its digital services and back-office systems.
When the ERP was in another cloud, even a simple API query required VPNs, tunnels, and layers of security. Now that everything is in one environment, integration is much faster and safer.

That need became more urgent as Micromed expanded its cloud-native health platform, designed to handle thousands of exams each day and support more advanced analytics. “The launch of our digital platform made integration with the ERP system essential to scale operations and back office functions, such as optimizing subscription, billing, and invoicing processes,” Broering explains.
Migrating the ERP system to Google Cloud became the final milestone in Micromed’s modernization journey. It closed the chapter on fragmented infrastructure and brought every critical system under one roof. “By consolidating these vital systems in a single platform, we gained operational efficiency and a unified view of all processes and data,” Broering continues. This decision was less about immediate gains and more about building a stable, integrated foundation that would allow Micromed to grow without the constant disruptions and complexity of the old environment.
Making daily operations easier for employees to run
Working with migration and implementation partner Tigabytes, Micromed rebuilt its ERP system on Google Cloud to bring stability and security to daily operations. The application now runs on Compute Engine, which provides the flexibility to host back-office processes at scale, while Cloud SQL manages financial data with automatic backups and high availability. Together, they ensure that payroll, invoicing, and reconciliation — once prone to delays — are now reliable and efficient.
Access control became much simpler. If someone leaves the company, their Google account is deleted and they automatically lose access to sensitive systems. That level of integration saved us hours of manual work and reduced risks.

Security was also a major concern before the migration. Broering recalls one of the biggest pain points: “Our legacy ERP lacked modern TLS security before the migration. Employees had to type an IP address or install software on Windows. Now, with Cloud Armor at the front, everything runs securely in the browser with a simple address.” This shift simplified access for employees and added a layer of protection that’s critical in healthcare environments.
Traffic spikes are now handled with Cloud Load Balancing, which distributes system access across servers so performance remains steady during peak demand. At the same time, Micromed’s digital health platform leverages Cloud Run to scale containerized services automatically.
That means the engineering team can deploy updates in minutes without worrying about provisioning servers or scheduling downtime. “By relying on services like Cloud Run and Cloud SQL, we can focus on code and innovation instead of infrastructure management,” Broering says.
Data also became an asset rather than a burden. BigQuery allows Micromed to analyze millions of cardiology records quickly, and Cloud Storage offers an economical way to archive years of exams while keeping them instantly available for doctors. “Exams that used to take nearly two seconds to load now appear in 200 milliseconds,” Broering says. “That difference may sound small, but in healthcare, speed matters. For a patient with chest pain, faster access to results can make all the difference.”
Cutting costs today to fund the future of cardiology
Migrating all core systems to Google Cloud delivered immediate improvements in cost, performance, and stability. Micromed cut infrastructure expenses by more than half, freeing resources to fund product development and expand digital services. “By reducing infrastructure costs, we got more than financial relief. It gave us room to invest in innovation, to hire, and to deliver new solutions faster to our clients,” says Broering.
Exam responsiveness also improved tenfold, a speed upgrade that enhances daily workflows and enables the company to deliver new features at a pace unheard of in its old environment. “The time needed to develop and launch new features or products dropped from weeks or months to just hours and days,” says Broering.
With this foundation in place, Micromed is now focused on the future of cardiology. The company is developing advanced AI models that can automatically measure ECG signals, suggest diagnostic paths, and increase cardiologists’ confidence. At the same time, it’s redesigning its hardware strategy around modular devices, equipment that can be upgraded with new digital capabilities instead of replaced entirely. This approach lowers costs for hospitals while accelerating the adoption of new technologies.
Broering is clear about Micromed’s approach: "We don’t do AI for the sake of AI. We build it for what truly matters: helping cardiologists be faster and more accurate, without losing control of the decision."
Looking further ahead, the company is preparing to expand internationally, pursuing regulatory approvals such as Food and Drug Administration (FDA) and the Conformité Européenne (CE), that will allow it to take its solutions beyond Brazil. For Micromed, the next chapter is about scaling its innovations globally and redefining how digital cardiology is delivered.
One of the most important advances is what we call Diagnostic Suggestion, which is like a co-pilot for cardiologists. It doesn’t replace them, but it increases confidence and reduces the chance of missing something important.
