Quantum Cloud Service is a private cloud platform developed in-house based on open-source technologies such as OpenStack, Kubernetes, and Ceph.

QCS adopts a multi-cloud strategy to ensure continuous, uninterrupted service.
This approach involves operating development, QA, and production systems on separate clouds, using Kubernetes as the foundational platform to maintain consistency between development and operations.
Furthermore, to reduce costs, development and QA systems are deployed on a private cloud, while the production system is deployed on a public cloud for stability and scalability.
One point to note is that, if necessary, the development and QA systems can be operated on a single cloud, separated by Namespaces.

Other benefits of QCS include establishing a sophisticated CI/CD system that enables rapid creation of runtime environments matching the source branch, and its ability to integrate with any public cloud offering Kubernetes services.
For virtual resources, Virtual instances are managed by OpenStack, Containers by Kubernetes, and Virtual Disks by Ceph.

Examples of implementations to date include the LG AI Research CI/CD platform, the Digital Companion Service (government project), the AI Speaker service (Company I), and the Jonathan AI Service Cloud (Company A – https://www.iacryl.com).
