Success Story
Multi-cloud observability and −54% costs in a QA environment
N5 Now is an Argentine software company founded in 2017 that builds digitalization platforms for banks and insurers, letting them modernize without replacing their legacy technology. Its solutions are used by banks such as Santander and Itaú, and insurers such as Assegur and Zurich. Craftech worked on the cloud infrastructure N5 operates for its own clients across AWS and Azure.
−54%
costs in a QA environment
Kafka → Amazon MSK
managed broker, no operational burden
Challenge
N5 runs a multi-client cloud infrastructure across AWS and Azure. One of the accounts lacked observability, making it hard to detect and resolve production incidents. In parallel, costs in other accounts were high due to oversized resources and the absence of autoscaling, and stateful services managed inside Kubernetes (Kafka, Redis, RabbitMQ, MongoDB) caused recurring operational issues.
Solution
Craftech implemented full observability with New Relic in the DEV and PRD environments of one of the accounts (AWS), with real-time visibility into applications, infrastructure and user experience (APM, logs with FluentBit, RUM, synthetic tests and dashboards). In parallel it analyzed and optimized costs in accounts on Azure/AKS, tuning pod requests/limits and oversized resources, and implemented node autoscaling with Karpenter. It also migrated the self-managed Kafka broker to Amazon MSK and automated QuickSight dashboard deployment versioned in Git.
Results
A 54% cost reduction was achieved in a QA environment through requests/limits optimization and resource tuning. One of the accounts gained comprehensive observability in DEV and PRD (APM, logs, infra, RUM and real-time alerts), Kafka was successfully migrated to Amazon MSK in DEV removing the broker's operational burden, node autoscaling was enabled with Karpenter, and QuickSight deployment became automated and versioned.
