Tokyo Gas Triumphs at CNCF Contest with Innovative Cloud Native Solutions
Tokyo Gas Triumphs at CNCF Contest with Innovative Cloud Native Solutions
On June 15, 2025, the Cloud Native Computing Foundation (CNCF) announced Tokyo Gas as the winner of the CNCF End User Case Study Contest. This recognition is due to Tokyo Gas’s exceptional application of Kubernetes, Argo CD, and Istio to revamp its largest digital membership platform. The company will present its transformative journey at the upcoming KubeCon + CloudNativeCon Japan 2025, taking place from June 16-17 in Tokyo.
The initiative was led by the myTOKYOGAS development team, which sought to address the limitations posed by their previous cloud migration strategy. Initially, the system operated on a monolithic architecture and rigid virtual machines, resulting in slow release cycles and scalability challenges. With the deregulation of Japan's energy market completed in the late 2010s, the urgency to improve business agility and enhance customer interactions became increasingly evident.
Yusuke Sugiyama, a software engineer at Tokyo Gas, noted, "Modernizing a legacy system is never easy, but by embracing a cloud-native architecture, we have built a flexible foundation for long-term innovation and competitiveness in a dynamic market." The strategic adoption of Kubernetes has been vital in reducing operational costs, allowing the company to better engage with its customers while streamlining various operations.
By leveraging cloud-native technologies, Tokyo Gas plays a pivotal role in minimizing data center energy consumption and promoting a transition towards a carbon-neutral future. The enhancements achieved through Kubernetes include dynamic scaling capabilities and decreased operational burdens, resulting in the following measurable outcomes:
- - A 30% cost saving from the dynamic scaling feature of Kubernetes and Karpenter.
- - A 30% reduction in operational efforts due to Kubernetes' auto-healing functionalities.
- - Accelerated deployment processes facilitated by GitOps and Argo CD.
- - A significant decrease in testing duration, from two months to just two weeks, utilizing k6 on Kubernetes.
Chris Aniszczyk, CTO of CNCF, commented, "Kubernetes, combined with Argo and Istio, is revolutionizing how organizations develop and manage software at scale. Tokyo Gas exemplifies the potential when these technologies converge. By embracing open source and cloud-native best practices, they have optimized their systems for agility and sustainability in a rapidly evolving energy landscape."
As Tokyo Gas continues to expand its microservices-based architecture, the implications of its success extend beyond innovation to encompass environmental accountability. Their forthcoming presentation at KubeCon + CloudNativeCon Japan will provide valuable insights into the cloud-native transformation process for teams just embarking on similar journeys.
