What Quality Cloud does

Quality Cloud株式会社 is a Tokyo-based private cloud infrastructure company established in October 2023 as a subsidiary of Quality Soft Corporation. It commercializes two integrated products: CGS (Cloud Green System), a power-efficient domestic cloud hardware platform that claims approximately 87% power consumption reduction via compact general-purpose computers, and OPEN Cypress, a unified management environment that orchestrates virtual machines, containers, and Kubernetes clusters through a single interface without requiring deep Kubernetes expertise. The platform is built on open-source foundations (Proxmox, Kubernetes, Ceph, Docker) wrapped with proprietary tooling.

The company sells to Japanese enterprises seeking sovereign cloud infrastructure independent of foreign hyperscalers, addressing data sovereignty, infrastructure cost escalation, and virtual server memory constraints faced by enterprise IT departments. Its business model combines a per-CPU-core monthly subscription for OPEN Cypress, one-time or project-based professional services (training, consulting, implementation, helpdesk), and hardware sale/operation/maintenance revenue from CGS deployments. Go-to-market is direct enterprise sales supported by pre-sales engineers, augmented by a strategic partnership with TIS Inc. (signed June 2025) for end-to-end planning-through-operations delivery.

The company is very small, with 1–10 disclosed employees, 230,000,000 JPY in registered capital, no external funding rounds, and operations limited to Japan. Its only named reference customer is its parent, Quality Soft Corporation, which serves 55+ countries and 85,000–90,000+ companies with security software. Leadership is led by CEO Kiyoshi Yoshitani (formerly of Hewlett-Packard Japan and Yokogawa Rent & Lease), with CTO Tsutomu Rokunohe and CRO Osamu Kakutani promoted to directors in June 2026 alongside the addition of KDDI co-founder Sachio Semmoto and founder Kiyoharu Ura to the board.

Direct peers

• Mirantis: Mirantis provides Kubernetes, OpenStack, and cloud-native platform services combining open source with proprietary management tooling. Closely comparable to Quality Cloud's OPEN Cypress + CGS approach of delivering unified VM/container management and private cloud infrastructure for enterprises, particularly those escaping proprietary virtualization stacks.
• SUSE: SUSE is an open-source enterprise infrastructure company offering Rancher (Kubernetes management), SUSE Virtualization, and private cloud platforms built on upstream open source. Directly comparable to Quality Cloud because both wrap open source components (Kubernetes, virtualization, Ceph-class storage) into enterprise-grade management stacks targeting on-prem private cloud deployments.

Broad incumbents

• Nutanix: Nutanix is an established hyperconverged infrastructure vendor offering integrated compute, storage, and virtualization for private cloud. Comparable to Quality Cloud as an alternative to traditional server-plus-virtualization stacks, but Nutanix is a much larger incumbent with proprietary hardware/software and broad global reach versus Quality Cloud's Japan-focused, open-source-rooted offering.
• Canonical: Canonical (Ubuntu) offers Charmed OpenStack, LXD, MicroCloud, and managed Kubernetes solutions built on open source for on-prem private cloud. Comparable to Quality Cloud in its open-source-rooted approach to delivering private cloud infrastructure for enterprises, though Canonical operates globally and at much larger scale.
• Red Hat (OpenShift): Red Hat (an IBM company) provides OpenShift as an enterprise Kubernetes platform along with RHEL, OpenStack, and Ansible for hybrid/private cloud. Comparable to Quality Cloud's Kubernetes/container and VM management focus, but Red Hat is a much larger global incumbent with broad enterprise footprint.
• Fujitsu: Fujitsu offers private cloud, hybrid cloud, and integrated systems for Japanese enterprises under its FUJITSU Cloud Service portfolio and PRIMERGY/PRIMEFLEX platforms. Comparable to Quality Cloud as a domestic enterprise cloud infrastructure option, but Fujitsu is a much larger incumbent with proprietary hardware, software, and a broad managed services portfolio across Japan.
• VMware (Broadcom): VMware is the dominant virtualization and private cloud platform globally and in Japan, now owned by Broadcom. Quality Cloud explicitly positions OPEN Cypress as a VMware migration target for enterprises seeking to escape the VMware/Broadcom stack, making VMware the principal incumbent competitor Quality Cloud is built to displace.

Emerging players

• ZStack: ZStack is an Asia-based private cloud platform offering IaaS, hyperconverged infrastructure, and container cloud built on open source components. Comparable to Quality Cloud as a regional open-source-rooted private cloud challenger, with particular overlap in the sovereign/domestic cloud positioning targeting Asian enterprises.

Regional players

• Internet Initiative Japan (IIJ): IIJ is a major Japanese internet/network and cloud services provider offering private cloud, hosting, and managed infrastructure to Japanese enterprises. Comparable to Quality Cloud as a Japan-focused cloud infrastructure provider addressing domestic enterprise customers, but IIJ operates at much larger scale and across a broader portfolio of services.
• SmartX: SmartX is an Asia-based hyperconverged infrastructure vendor offering distributed storage and integrated compute/storage for private cloud deployments. Comparable to Quality Cloud in its open-source-rooted hardware/software stack approach and Asia regional focus, though SmartX has stronger traction in China rather than Japan.
