OpenCloud 4.0: The cloud future for companies
In 2025, cloud technology is at a new level of maturity. With OpenCloud 4.0, companies are experiencing an innovative platform that combines multi-tenancy, OpenSearch integration and support for modern deployment methods such as Helm charts for Kubernetes in a standardized environment. Especially for companies that want to scale their IT capacities flexibly and at short notice – for example by renting laptops or tablets for projects and events – there are new opportunities to build their infrastructure efficiently and securely.
But what exactly is behind OpenCloud 4.0? In this article, we take an in-depth look at the current developments surrounding OpenCloud and show what it means for companies in the areas of IT, technology and mobile devices – and specifically for your rental fleet if you want to provide, manage or easily scale devices.
What is OpenCloud 4.0?
OpenCloud 4.0 is the latest generation of an open, cloud-native IT service platform that has been developed especially for enterprise use. The focus is on the following key points:
- Multi-client capability (“multitenancy”): Several customer or departmental systems can be operated securely on the same infrastructure.
- OpenSearch integration: For powerful, distributed search and analysis functions on big data.
- Kubernetes optimization with Helm charts: For simple, scalable deployment of container-based applications.
At the same time, OpenCloud remains open: It integrates existing open source systems and allows modular extensions. For companies that already rely on modern DevOps and container strategies or manage an extensive fleet of tablets for rental, this opens up new options in automation and monitoring.
Advantages of OpenCloud 4.0 for companies
The introduction of OpenCloud 4.0 brings tangible benefits for companies in virtually every industry – especially for service providers, IT managers and technology rental managers. Here are some of the key benefits:
| Function | Advantage for companies |
|---|---|
| Multi-client capability | Parallel, secure operation of multiple client systems. Ideal for MSPs or for device fleets with a client structure, for example if you manage several Galaxy Tab S8 Ultra for different projects at the same time. |
| OpenSearch | Fast data analysis & visualization e.g. of telemetry data, utilization or error messages of the device fleet – especially helpful for many mobile workstations or for event use with rented MacBook Air 15 inch devices. |
| Kubernetes with helmet | Scale workloads automatically. Ideal for deploying monitoring systems or service apps on rental devices, for example if you rent the MacBook Pro 13 inch (2022) and want to customize it. |
| Automation | Consistent CI/CD pipelines enable faster product provision and updates for rental solutions. |
| Open source integration | Avoidance of vendor lock-ins and more flexibility in system selection. |
New possibilities for mobile device fleets
OpenCloud 4.0 can also bring real added value if you as a provider or company rent out or manage mobile devices, such as Google Pixel 7 smartphones for temporary projects:
- OpenSearch can be used to centrally evaluate device statuses – such as charge status, frequency of use, location or error messages.
- Multi-client capability allows different customers or locations to be managed on one platform – with clearly separated dashboards and access rights.
- Kubernetes with Helm enables the flexible rollout of MDM systems, diagnostic software or individual applications on the end devices.
Imagine managing hundreds of borrowed tablets in different rooms or even publicly displayed areas. With a suitable tablet floor stand, you can present your content securely and attractively – while updates, security and analysis are conveniently handled centrally thanks to OpenCloud 4.0.
Case study: Device management in the healthcare sector
A provider of medical devices and tablets in care facilities uses OpenCloud 4.0 to centrally manage over 5,000 mobile devices in Germany:
- MDM systems are rolled out on rented tablets via Helm charts, individually adapted to each institution.
- Via OpenSearch, technicians can see the device status in real time and local problems can be solved remotely.
- Thanks to client separation, operators manage several clinics efficiently in one dashboard, without overlaps.
The result: a 40% reduction in downtime, faster updates, fewer IT staff required on site – and a significant increase in customer satisfaction.
OpenCloud 4.0 in practice: technical requirements
Even if OpenCloud 4.0 is a modern and open platform, a decision should be made before implementation as to whether the company’s own IT fulfills these basic requirements or can be expanded:
- Container infrastructure available or possible (Kubernetes, Docker)
- CI/CD pipelines for automated deployments desired
- Monitoring or logging requirements (e.g. for the laptop fleet in the field or the app status).
- Several clients or customer systems in use
For companies that do not wish to operate their own servers, there are now also Managed OpenCloud Services that offer infrastructure and support through external partners or rental platforms.
Why it’s worth relying on OpenCloud 4.0 as early as 2025
Digital transformation is no longer a buzzword, but a prerequisite for efficient, competitive companies. OpenCloud 4.0 offers exactly the tools that are needed today:
- High scalability for growing numbers of devices and customers
- Flexibility through modular architectures with open source
- Faster time-to-market through automation
- Secure and separate systems through multitenancy
- Intelligent monitoring and analysis with OpenSearch
This gives technology providers, local IT system houses and device rental companies in particular a considerable advantage – for example, if they use OpenCloud 4.0 for management in the context of tablet rental or the professional provision of laptops on a temporary basis.
If you rent out, network or monitor products such as tablets, notebooks or mobile terminals, OpenCloud 4.0 can become a central component of your digital strategy. Combine the platform with modern rental solutions – such as the MacBook Air 15″ for rental or flexible Google Pixel 7 rental devices – and sustainably increase efficiency, service quality and sales.
FAQ: Frequently asked questions about OpenCloud 4.0
- Is OpenCloud 4.0 a product or an architecture?
- OpenCloud 4.0 is an architecture platform that consists of several open components (OpenSearch, Kubernetes, etc.) – partly as open source, partly supplemented by company-specific extensions.
- Do I have to operate my own servers?
- No, OpenCloud 4.0 can also be obtained as a managed service – or via existing cloud providers. The desired level of control determines the choice of infrastructure.
