It integrates enterprise-grade NVIDIA GPUs such as the H100, H200, and L40s, as well as specialized AI accelerators like Intel Gaudi, enabling massive parallel processing for compute-intensive applications. GPU-accelerated instances extend cloud infrastructure with dedicated graphics processors so virtual machines can perform complex calculations and data-heavy operations much faster than conventional servers. It is particularly suitable for artificial intelligence, deep learning, and data science tasks that involve training models on large datasets or performing high-speed inference operations. It also supports big data analytics, scientific simulations, and visualization workloads such as 3D rendering or modeling that require high computational throughput. 45,199 Ratings Visit Website OpenMetal OpenMetal delivers hosted private cloud and bare metal infrastructure that gives organizations a real alternative to building their own private cloud or committing to a hyperscaler. Our private cloud platform is built on OpenStack and Ceph, giving customers full access to a proven, open source cloud stack without the overhead of managing it themselves. That means more control, more transparency, and a predictable cost structure that public cloud pricing rarely offers at scale. For organizations that need dedicated infrastructure without the operational burden, we offer fully hosted bare metal servers that can run standalone or integrate directly with an OpenMetal private cloud. Deployment is fast, hardware is dedicated, and pricing is fixed so you can focus on the work, not the bill. 40 Ratings Visit Website Nexcess Managed Cloud Nexcess is a managed cloud hosting platform engineered to simplify infrastructure while delivering high performance, security, and scalability for business-critical workloads.

About Stackscale’s Private Cloud is a hybrid solution between the traditional environment, robust and secure, and Public Cloud services, functional, flexible and scalable. In combination with our oversized network, our state-of-the-art data centers in Europe and our 24/7 specialized technical support team, our private cloud environments offer great performance, availability and security. We can consolidate two full racks housing networking gear and servers in just two nodes using network storage, reducing power usage by up to 95%. Designing a private cloud environment meant to be run at Stackscale is an easy task, as there are by far less variables to play with. Important design parameters are RAM and persistent storage size. IOPS, bandwidth and CPU requirements are less critical, since these are prevented from becoming a bottleneck in most scenarios. Our bare-metal servers are fully configurable and offer a level of control that matches in-house solutions.
