The U.S. Department of Defense (DoD) is increasingly adopting open-source software (OSS) and DevSecOps principles to modernize its software development processes, prioritizing speed, quality, and security. This shift is part of a broader strategy to create an ecosystem of software factories, utilizing tools like Platform One's Big Bang, which provides infrastructure provisioning, CI/CD pipelines, and security scanning. Big Bang 2.0 has integrated open-source projects from Grafana Labs, such as Grafana Loki, Grafana, and Grafana Tempo, to enhance observability with lower resource costs and no license requirements. Grafana offers a centralized platform for monitoring and improving software reliability by consolidating data from various sources, enabling DoD software factories to proactively manage their systems with role-based dashboards and comprehensive insights into key performance indicators.
