With <strong>OpenCloud 4.0<\/strong>, 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 &#8211; for example by <a href=\"https:\/\/get-it-easy.de\/en\/rent\/computers\/laptops\/\" target=\"_blank\">renting laptops<\/a> or <a href=\"https:\/\/get-it-easy.de\/en\/rent\/tablets\/\" target=\"_blank\">tablets for projects and events<\/a> &#8211; there are new opportunities to build their infrastructure efficiently and securely.  <\/p>\n\n<p>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 &#8211; and specifically for your rental fleet if you want to provide, manage or easily scale devices. <\/p>\n\n<h2>What is OpenCloud 4.0?<\/h2>\n\n<p>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: <\/p>\n\n<ul>\n  <li><strong>Multi-client capability<\/strong> (&#8220;multitenancy&#8221;): Several customer or departmental systems can be operated securely on the same infrastructure.<\/li>\n  <li><strong>OpenSearch integration<\/strong>: For powerful, distributed search and analysis functions on big data.<\/li>\n  <li><strong>Kubernetes optimization with Helm charts<\/strong>: For simple, scalable deployment of container-based applications.<\/li>\n<\/ul>\n\n<p>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 <a href=\"https:\/\/get-it-easy.de\/en\/rent\/tablets\/\" target=\"_blank\">manage an extensive fleet of tablets for rental<\/a>, this opens up new options in automation and monitoring. <\/p>\n\n<h2>Advantages of OpenCloud 4.0 for companies<\/h2>\n\n<p>The introduction of OpenCloud 4.0 brings tangible benefits for companies in virtually every industry &#8211; especially for service providers, IT managers and technology rental managers. Here are some of the key benefits: <\/p>\n\n<table>\n  <thead>\n    <tr>\n      <th>Function<\/th>\n      <th>Advantage for companies<\/th>\n    <\/tr>\n  <\/thead>\n  <tbody>\n    <tr>\n      <td>Multi-client capability<\/td>\n      <td>Parallel, secure operation of multiple client systems. Ideal for MSPs or for device fleets with a client structure, for example if you manage several <a href=\"https:\/\/get-it-easy.de\/galaxy-tab-s8-ultra-mieten\/\" target=\"_blank\">Galaxy Tab S8 Ultra<\/a> for different projects at the same time. <\/td>\n    <\/tr>\n    <tr>\n      <td>OpenSearch<\/td>\n      <td>Fast data analysis &#038; visualization e.g. of telemetry data, utilization or error messages of the device fleet &#8211; especially helpful for many mobile workstations or for event use with <a href=\"https:\/\/get-it-easy.de\/macbook-air-15-m2-mieten\/\" target=\"_blank\">rented MacBook Air 15 inch<\/a> devices.<\/td>\n    <\/tr>\n    <tr>\n      <td>Kubernetes with helmet<\/td>\n      <td>Scale workloads automatically. Ideal for deploying monitoring systems or service apps on rental devices, for example if you rent <a href=\"https:\/\/get-it-easy.de\/en\/rent\/macbook-pro-13-2022\/\" target=\"_blank\">the MacBook Pro 13 inch (2022)<\/a> and want to customize it. <\/td>\n    <\/tr>\n    <tr>\n      <td>Automation<\/td>\n      <td>Consistent CI\/CD pipelines enable faster product provision and updates for rental solutions.<\/td>\n    <\/tr>\n    <tr>\n      <td>Open source integration<\/td>\n      <td>Avoidance of vendor lock-ins and more flexibility in system selection.<\/td>\n    <\/tr>\n  <\/tbody>\n<\/table>\n\n<h2>New possibilities for mobile device fleets<\/h2>\n\n<p>OpenCloud 4.0 can also bring real added value if you as a provider or company rent out or manage mobile devices, such as <a href=\"https:\/\/get-it-easy.de\/google-pixel-7-mieten\/\" target=\"_blank\">Google Pixel 7 smartphones for temporary projects<\/a>:<\/p>\n\n<ol>\n  <li>OpenSearch can be used to centrally evaluate device statuses &#8211; such as charge status, frequency of use, location or error messages.<\/li>\n  <li>Multi-client capability allows different customers or locations to be managed on one platform &#8211; with clearly separated dashboards and access rights.<\/li>\n  <li>Kubernetes with Helm enables the flexible rollout of MDM systems, diagnostic software or individual applications on the end devices.<\/li>\n<\/ol>\n\n<p>Imagine managing hundreds of borrowed tablets in different rooms or even publicly displayed areas. With a suitable <a href=\"https:\/\/get-it-easy.de\/tablet-bodenstaender-schwarz-mieten\/\" target=\"_blank\">tablet floor stand<\/a>, you can present your content securely and attractively &#8211; while updates, security and analysis are conveniently handled centrally thanks to OpenCloud 4.0. <\/p>\n\n<h2>Case study: Device management in the healthcare sector<\/h2>\n\n<p>A provider of medical devices and tablets in care facilities uses OpenCloud 4.0 to centrally manage over 5,000 mobile devices in Germany:<\/p>\n\n<ul>\n  <li>MDM systems are rolled out on <a href=\"https:\/\/get-it-easy.de\/en\/rent\/tablets\/\" target=\"_blank\">rented tablets<\/a> via Helm charts, individually adapted to each institution.<\/li>\n  <li>Via OpenSearch, technicians can see the device status in real time and local problems can be solved remotely.<\/li>\n  <li>Thanks to client separation, operators manage several clinics efficiently in one dashboard, without overlaps.<\/li>\n<\/ul>\n\n<p>The result: a 40% reduction in downtime, faster updates, fewer IT staff required on site &#8211; and a significant increase in customer satisfaction.<\/p>\n\n<h2>OpenCloud 4.0 in practice: technical requirements<\/h2>\n\n<p>Even if OpenCloud 4.0 is a modern and open platform, a decision should be made before implementation as to whether the company&#8217;s own IT fulfills these basic requirements or can be expanded:<\/p>\n\n<ul>\n  <li>Container infrastructure available or possible (Kubernetes, Docker)<\/li>\n  <li>CI\/CD pipelines for automated deployments desired<\/li>\n  <li>Monitoring or logging requirements (e.g. for the <a href=\"https:\/\/get-it-easy.de\/en\/rent\/computers\/laptops\/\" target=\"_blank\">laptop fleet in the field<\/a> or the app status).<\/li>\n  <li>Several clients or customer systems in use<\/li>\n<\/ul>\n\n<p>For companies that do not wish to operate their own servers, there are now also <strong>Managed OpenCloud Services<\/strong> that offer infrastructure and support through external partners or rental platforms.<\/p>\n\n<h2>Why it&#8217;s worth relying on OpenCloud 4.0 as early as 2025<\/h2>\n\n<p>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: <\/p>\n\n<ul>\n  <li>High scalability for growing numbers of devices and customers<\/li>\n  <li>Flexibility through modular architectures with open source<\/li>\n  <li>Faster time-to-market through automation<\/li>\n  <li>Secure and separate systems through multitenancy<\/li>\n  <li>Intelligent monitoring and analysis with OpenSearch<\/li>\n<\/ul>\n\n<p>This gives technology providers, local IT system houses and device rental companies in particular a considerable advantage &#8211; for example, if they use OpenCloud 4.0 for management in the context of <a href=\"https:\/\/get-it-easy.de\/en\/rent\/tablets\/\" target=\"_blank\">tablet rental<\/a> or the professional provision of <a href=\"https:\/\/get-it-easy.de\/en\/rent\/computers\/laptops\/\" target=\"_blank\">laptops on a temporary basis<\/a>.<\/p>\n\n<p>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 &#8211; such as the <a href=\"https:\/\/get-it-easy.de\/macbook-air-15-m2-mieten\/\" target=\"_blank\">MacBook Air 15&#8243; for rental<\/a> or flexible <a href=\"https:\/\/get-it-easy.de\/google-pixel-7-mieten\/\" target=\"_blank\">Google Pixel 7 rental devices<\/a> &#8211; and sustainably increase efficiency, service quality and sales. <\/p>\n\n<h2>FAQ: Frequently asked questions about OpenCloud 4.0<\/h2>\n\n<dl>\n  <dt>Is OpenCloud 4.0 a product or an architecture?<\/dt>\n  <dd>OpenCloud 4.0 is an architecture platform that consists of several open components (OpenSearch, Kubernetes, etc.) &#8211; partly as open source, partly supplemented by company-specific extensions.<\/dd>\n\n  <dt>Do I have to operate my own servers?<\/dt>\n  <dd>No, OpenCloud 4.0 can also be obtained as a managed service &#8211; or via existing cloud providers.
