Kubernetes, while an industry standard for container orchestration, presents significant complexity challenges as organizations scale their deployments, as evidenced by PicPay's experience. PicPay, a leading digital wallet and bank in Latin America, faced difficulties in managing their extensive Kubernetes infrastructure, which includes over a hundred clusters and thousands of microservices. The complexity led to fragmented IT stacks and inefficient log-heavy analysis methods, prompting PicPay to adopt a strategic Kubernetes platform engineering approach. This approach involved breaking down large clusters, standardizing infrastructure, and integrating metrics, traces, and logs to improve observability and cost efficiency. Partnering with Dynatrace, PicPay consolidated its toolset, enhancing visibility and scalability while reducing maintenance costs. This strategic shift underscores the importance of platform engineering in managing Kubernetes complexity, emphasizing the need for a unified toolset and early implementation to simplify infrastructure and improve operational efficiency.
