Implementing Kubernetes at scale presents challenges, from efficient resource management to ensuring the resilience of critical applications. In this session, we will discuss approaches to cluster provisioning, deployment automation, secure upgrades, and adoption of cell-based architecture using k8s. Itaú Unibanco will share its journey, demonstrating how they used IaC and GitOps through a provisioning framework at scale to create a multi-cluster architecture for critical applications. Join us to discover valuable insights on resilience and scalability in Kubernetes' environments in the cloud.
