As virtualization licensing models undergo significant restructuring and the adoption of private AI accelerates, enterprises face mounting pressure to transform their IT environments. Demand is growing simultaneously for data sovereignty, on-premises GPU infrastructure, and cloud-native architectures. The challenge for IT teams extends beyond system modernization to require a comprehensive shift in governance, computing resources, and data flows.

Against this backdrop, Bigstack centered its Bigshare 2026 Technology Summit around the theme "Open Gravity," exploring how open source technologies can reduce the risks of vendor lock-in, increase infrastructure autonomy, and ultimately accelerate enterprise cloud transformation.

Kai Kuo, Co-founder and Executive Vice President of Bigstack, emphasized, "Openness is competitiveness, and transparency is the foundation of trust. Drawing on experience from a telecommunications security audit project, the team successfully remediated over a thousand vulnerabilities in just three months, showcasing the resilience and dependability of open-source architectures. Building on these achievements, Bigstack plans to launch an on-premises AI platform for data governance by the end of the year. This platform will enable enterprises to maintain full control over their data while leveraging private cloud computing resources.

Zero-Downtime Upgrades: CubeCOS Redefines Infrastructure Operations

Enterprises face the risk of service disruption during virtualization platform upgrades. In response, Bigstack Technology Evangelist Brian Su announced the release of CubeCOS 3.1 in the first quarter. It is designed to significantly reduce upgrade friction and operational complexity.

CubeCOS 3.1 introduces live and cold migration capabilities and one-click rolling updates. It integrates health checks and automated rollback mechanisms, transforming traditionally high-risk upgrades into routine maintenance operations. The release also adds a Traditional Chinese user interface, enhanced IPMI-based remote management, and OCI storage support, further improving operational efficiency and manageability.

Continuing the platform's evolution, Bigstack Chief Operating Officer Gary Hsueh unveiled CubeCMP 2.1, built around the principles of greater flexibility, automation, and visibility. Through advanced network controls, API-driven self-service capabilities, and multi-dimensional operational insights, CubeCMP 2.1 further strengthens the management of hybrid and multi-cloud environments.

Beyond the Lab: Open Source Infrastructure Accelerates AI Adoption

Beyond product innovation, Bigstack is extending the value of open source into education and research. According to Yang Chao-Tung, Director of the Library and Information Center and Chair of the Department of Computer Science at Tunghai University, AI talent development should not be limited to models and algorithms alone. Equally important is cultivating an understanding of the underlying infrastructure and governance frameworks that enable AI systems to operate effectively.

To connect research with real-world use, the university's HPC Lab used CubeCOS to combine existing server resources and create a hyperconverged platform. This environment supports various AI applications, such as echocardiography analysis and tennis match analytics. It enables researchers to accelerate experimentation and production deployment.

Yang Chao-Tung, Director of the Library and Information Center and Chair of the Department of Computer Science at Tunghai University, emphasized that AI talent development should encompass not only models and algorithms, but also a solid understanding of underlying infrastructure and governance capabilities.

In the semiconductor research domain, Dr. Lin-Hung Lai of the Institute of Electronics at National Yang Ming Chiao Tung University explained how his team met the demanding requirements of IC design workloads using CubeCMP. The platform uses virtualization template management to enable researchers to respond more efficiently to fluctuating and peak computing demands

The team has also developed the AMP account management platform, which integrates virtual machine provisioning with electronic signature workflows. Combined with VDI-based remote desktop access and screen recording capabilities, the solution establishes a comprehensive audit framework that maintains separation between research and teaching environments while strengthening information security and compliance.

Migration as Governance: CubeDPX Helps Enterprises Break Free from Virtualization Lock-In

As enterprises reassess their virtualization strategies, data migration has emerged as a critical factor in infrastructure modernization. To address this challenge, Bigstack partnered with Trilio to introduce CubeDPX, a solution designed to simplify migration while ensuring data protection and operational continuity.

According to David Safaii, Co-founder and Chief Evangelist of Trilio, the greatest challenge in migration is not speed, but data integrity. Compared with a one-time cutover approach, phased incremental migration better aligns with the operational realities of enterprise environments.

Bigstack engineer Terry Shih further explained that CubeDPX adopts a "restore-first" design philosophy. By providing one-click recovery, selective recovery, and in-place recovery capabilities, the platform transforms migration from a high-risk project into a routine operational process.

Meanwhile, Jason Cheng, technical director of Jason Tools, explained how CubeCOS was integrated with the Graylog centralized logging platform. The team established 147 processing rules, 11 dashboards, 210 visualization components, and 12 alert policies through a six-layer data pipeline architecture, significantly enhancing observability across the open-source environment. The solution has also been contributed back to the community through GitHub.

Jason noted that more than 60% of the world's top 1,000 commercial software products rely on open-source technologies. This means that security is no longer the primary concern in enterprise adoption. Instead, organizations are increasingly evaluating the strength of vendor support and focusing on implementing three key principles: open standards, open source, and open formats.

Through a six-layer data pipeline architecture, the team built a centralized logging platform with comprehensive monitoring and analytics capabilities, while also open-sourcing the implementation on GitHub.

Concluding the forum, Bigstack Technology Evangelist Brian Su summarized the event around three key pillars: open standards, automation, and open licensing. He emphasized that only through open source can organizations sustain innovation in a rapidly evolving cloud landscape.

By combining local collaboration with a long-term commitment to customer value, Bigstack continues to build a transparent and trusted open-source ecosystem that accelerates cloud-native adoption and strengthens long-term enterprise competitiveness.

More than a showcase of technological achievements, Bigshare 2026 marked a new starting point for the expansion of the CubeCOS open-source ecosystem. It also signaled a new phase in the convergence of cloud computing, AI, and edge computing. With openness as its gravitational force, Bigstack is bringing together ecosystem partners to create shared value and drive industry innovation.

Following its recognition with the IMA (IT Matters Award) Best Social Impact Award 2025, Bigstack has further demonstrated its growing influence across both industry and open-source communities. Looking ahead, CubeCOS will next be featured at the Open Source Taiwan Pavilion at COMPUTEX, showcasing how open collaboration can empower enterprise cloud transformation.
