Over the past five years, Logz.io's DevOps Pulse survey has highlighted the growing adoption of open-source observability solutions, driven by the need for cost-effective and flexible alternatives to proprietary tools. Open-source projects, such as OpenTelemetry, have become essential for organizations aiming to standardize metrics, logs, and traces while avoiding vendor lock-in. Large enterprises, including banks, are increasingly prioritizing open-source solutions not only for their cost-efficiency but also to future-proof their data collection strategies. However, challenges such as talent shortages and the need for ongoing maintenance persist, with usability and scalability remaining significant hurdles. Despite these issues, the open-source community continues to thrive, offering integration, community support, and cost benefits. As companies navigate economic pressures, many are turning to cloud providers and specialized vendors to manage these open-source solutions, ensuring they remain up-to-date and efficient.
