Breaking Free from Vendor Lock-In: Nubank DIY Observability Success
Nubank is the largest digital bank outside Asia, operating in Brazil, Mexico, and Colombia, and serving over 120 million customers. As a cloud-native company, Nubank distributed digital environment relies on more than 4,000 microservices, generating nearly 1 petabyte of monitoring logs daily.
