What is a Private Cloud? – Fundamentals of Private Cloud Computing
Private Cloud in Cloud Computing: Differentiation from Public and Hybrid Cloud
In the ecosystem of cloud computing, the private cloud represents a deployment model in which all IT resources are reserved exclusively for a single organisation (single-tenant). The fundamental difference to the public cloud lies in multi-tenancy: while in the public cloud multiple customers share a physical infrastructure (multi-tenant), the private cloud guarantees complete isolation. The hybrid cloud is not a separate model but an architecture that strategically connects both worlds: it integrates a private cloud with one or more public clouds to place workloads optimally depending on requirements.
Private Cloud – What the Term Means in a Corporate Context
In the corporate context, “private cloud” means above all sovereignty. It is not just about own servers, but about full control over your own IT environment. This includes the free choice of technologies (hypervisor, management software), exclusive authority over security policies, and the physical location of the data (data sovereignty). A private cloud is thus the technical implementation of a strategic decision for maximum control, security and compliance.
Private Cloud Computing for Enterprises – Benefits, Use Cases and Cost Efficiency
Why Companies Choose Private Cloud Solutions
Organizations opt for private cloud computing for strategic reasons. The main drivers include the need to comply with strict industry-specific and regulatory requirements (e.g. GDPR, BaFin, HIPAA), the protection of intellectual property and sensitive customer data, as well as the requirement for guaranteed, predictable performance for mission-critical applications. In addition, a private cloud enables better cost control (TCO) for consistent workloads compared to the often unpredictable, usage-based costs of the public cloud.
Scalability, Security and Performance: The Core Advantages of the Business Private Cloud
The Business Private Cloud is built on three pillars:
- Security: Complete infrastructure isolation minimizes the attack surface. Companies maintain full control over firewalls, network segmentation, and access permissions.
- Performance: Own servers eliminate the “noisy neighbor” issue, where other tenants affect performance. Critical applications receive the guaranteed compute power they require.
- Scalability: A private cloud is designed to grow with your business needs. Resources can be dynamically allocated within the cluster, and the infrastructure can be modularly expanded as needed.

Private Cloud Business Use Cases: From ERP Systems to AI Workloads
The use cases for a private cloud are diverse and demanding. These include running resource-intensive ERP systems (e.g. SAP HANA), high-availability databases, and development environments for in-house software. Increasingly, private clouds are also becoming the foundation for modern AI and machine learning workloads, as they support the integration of specialized hardware such as GPUs and provide the necessary security for sensitive training data.
Private Cloud Compared to Traditional IT Infrastructures
Unlike traditional, siloed IT infrastructures with servers for individual applications, the private cloud offers a dynamic, virtualized, and automated operating model. Instead of manual configuration, it enables automated resource provisioning via self-service portals (Infrastructure-as-a-Service). This accelerates processes, increases efficiency, and turns IT into an agile enabler for the business.

On-Premise Private Cloud & Private Data Center – Control and Security in Your Own Data Center
On-Premise Solution vs. Cloud: What Are the Differences?
“On-Premise” refers to the physical location of the infrastructure — within your own organization. “Cloud” describes the operating model — virtualized, automated, and scalable. An on-premise private cloud combines both: it is a cloud architecture operated within your own private data center. This setup provides maximum control over physical security and data location.
Building an On-Premise Private Cloud – Infrastructure and Server Requirements
Building an on-premise private cloud requires a carefully planned infrastructure. The foundation consists of high-performance servers, flexible storage systems (e.g. SDS), and high-speed networking components (switches, firewalls). On top of this lies the software layer, comprising a hypervisor (e.g. KVM), virtualization software, and a cloud management platform.
The On-Premise Server as the Heart of the Private Cloud
The on-premise server is the fundamental building block of any private cloud. As part of a cluster, it provides the compute power. Selecting the right server configuration — from CPU performance and RAM capacity to specialized accelerator cards (GPUs) — is crucial for the performance of the entire cloud environment.
The Private Data Center: Maximum Data Sovereignty and Compliance
A private data center provides the ultimate assurance of data sovereignty. Organizations retain 100% physical control over their server and data. This is often a mandatory requirement for entities in critical infrastructure sectors (KRITIS) or for companies subject to the strictest national data protection regulations.
Technical Foundation of the Private Cloud – Clusters, Virtualization, and Management
Private Cloud Clusters: Architecture, Scaling, and High Availability
A private cloud cluster consists of a group of servers (nodes) that operate as a single, large resource. If one node fails, the others seamlessly take over its tasks — this mechanism is known as a failover cluster and ensures high service availability. Scaling is achieved simply by adding more nodes to the cluster, resulting in a linear increase in overall performance.
OpenStack Clusters and Kubernetes as the Foundation of Modern Private Clouds:
OpenStack Clusters:
OpenStack is a well-established open-source framework for delivering Infrastructure-as-a-Service (IaaS). It centrally manages compute, networking, and storage, enabling flexible resource allocation.
Kubernetes:
Kubernetes has established itself as the de facto standard for container orchestration. It enables the creation of a flexible, application-centric Platform-as-a-Service (PaaS) layer within the private cloud and allows automated deployment, scaling, and management of containerized applications.
FishOS as the Management and Storage Layer for Private Clouds
While OpenStack and Kubernetes primarily cover virtualization and orchestration, FishOS provides a stable and efficient infrastructure layer underneath.
FishOS is based on Ceph and combines storage, network, and compute management within a single platform. It offers:
- Software-Defined Storage (SDS) with Ceph for high availability and data redundancy,
- Integrated monitoring and management of all cloud resources,
- Simplified deployment of on-premise private clouds, particularly in enterprise data centers.
As a result, FishOS becomes an ideal solution for organizations looking to build a fully integrated on-premise private cloud with a focus on storage, security, and performance.

Cloud Management Platform – Managing Compute, Storage, and Networking
The Cloud Management Platform (CMP) is the central “brain” of the private cloud. It provides a unified interface for managing all resources, automating processes, monitoring utilization, and handling user permissions. It is the essential tool for efficient and secure operations. FishOS can function as part of a CMP or, in combination with OpenStack, form a complete management layer. This creates a unified control center that manages cluster, container, and storage components — ideal for organizations requiring maximum transparency and efficiency.
Compute Cluster Cloud: Performance for Demanding Business Applications
A compute cluster within the cloud is specifically designed to deliver maximum computing power for demanding applications. By pooling the CPU and RAM resources of multiple servers, even complex simulations, big data analytics, or rendering tasks can be processed efficiently.
In combination with tools like Kubernetes or FishOS Ceph Storage, this enables high-performance, fault-tolerant environments for machine learning, analytics, or 3D rendering.
