Cortex, a scalable Prometheus implementation and CNCF project, is poised for significant growth despite Grafana Labs' shift in focus to Grafana Mimir for long-term storage solutions. While Cortex has been praised for its ability to handle large-scale data and provide a centralized monitoring experience for enterprises, it faces challenges such as reliance on NoSQL stores and a need for improved documentation and user experience. Efforts are underway to eliminate the NoSQL dependency by integrating object storage solutions, facilitating interoperability with Thanos, and enhancing user onboarding through better documentation and UI improvements. Cortex's enterprise appeal is underscored by its ability to centrally manage metrics and alerts, exemplified by its use at companies like GoJek. The goal for 2020 is to enhance Cortex's adoption by addressing these challenges and exploring potential synergies with Thanos, ultimately driving broader enterprise adoption of Prometheus.
