Lunar Way, a Denmark-based fintech company, is revolutionizing the banking sector by implementing digital-only transactions and integrating APIs with traditional banking systems, allowing for more flexible and consumer-friendly banking services. As the company rapidly expands its suite of products, including credit cards and travel cards, it faces challenges in managing the increasing complexity and diversity of its systems. Initially using Elasticsearch and Kibana for log management, Lunar Way transitioned to Humio, an on-premises solution that accommodates their private AWS cluster without the need for external log exports. Humio's schema-less log management offers Lunar Way comprehensive insights across its microservices architecture, enhancing their ability to identify and prevent potential issues quickly. This transformation has been pivotal in maintaining an agile development process, enabling rapid deployment cycles, and supporting their extensive use of Kubernetes for managing 35–40 microservices. Humio's adaptability extends beyond expected uses, assisting in real-time feedback during mobile application testing, thus shortening development cycles and accelerating feature rollouts. Lunar Way's innovative approach, supported by Humio's log management capabilities, positions them at the forefront of fintech innovation in Denmark and potentially on a global scale.
