Best Virtualization Software for Linux of 2025 - Page 2

Sphere 3D’s Glassware 2.0 platform is designed for simplicity, adaptability, and scalability, effectively removing the complicated processes involved in creating, executing, and managing application hosting environments, thereby providing secure and scalable server-based computing advantages to everyone. By separating the application from the underlying operating system, Glassware 2.0 enhances the longevity of applications. It has the capability to virtualize Microsoft Windows applications in 16, 32, and 64-bit formats*, delivering them with native performance to a wide range of end-user devices such as Chromebooks, Windows 10 systems, iPads, thin clients, and various tablets. Employing a container-based strategy for application virtualization on servers, Glassware 2.0 also features a remote presentation functionality that guarantees smooth application delivery to end-user devices. In contrast to hypervisor-based methods, Glassware 2.0 ensures that the application’s host operating system is never installed on the server, streamlining the entire process. This innovative approach not only simplifies deployment but also enhances user experience across multiple platforms.

KVM, which stands for Kernel-based Virtual Machine, serves as a comprehensive virtualization solution for Linux systems operating on x86 hardware equipped with virtualization capabilities (such as Intel VT or AMD-V). It comprises a loadable kernel module, known as kvm.ko, that underpins the essential virtualization framework, along with a processor-specific module, either kvm-intel.ko or kvm-amd.ko. By utilizing KVM, users can operate several virtual machines that run unaltered Linux or Windows operating systems. Each virtual machine is allocated its own set of virtualized hardware components, including a network interface card, storage, graphics adapter, and more. KVM is an open-source project, with its kernel component integrated into the mainline Linux kernel since version 2.6.20, while the userspace aspect has been incorporated into the mainline QEMU project starting from version 1.3. This integration enables widespread deployment and support for various virtualization applications and services.

IBM PowerVC is a virtualization management solution based on OpenStack, created to streamline the deployment and oversight of virtual machines across IBM Power Systems that operate AIX, IBM i, and Linux. It allows for quick deployment, significantly shortening the time required to realize value through easy installation and configuration. With a user-friendly interface, it reduces the necessity for specialized training, ultimately boosting administrator efficiency. PowerVC enhances resource utilization by promoting resource pooling and establishing placement policies, which helps in optimizing IT expenses. The Dynamic Resource Optimizer (DRO) automates workload balancing within host groups based on set policies, ensuring that performance remains at its peak. Furthermore, VM templates foster consistency and standardization, making deployments smoother and less labor-intensive. Additional key features include automated I/O configuration that supports both mobility and high availability, along with the effortless import and deployment of workload images, making it an invaluable tool for IT management. Overall, PowerVC not only simplifies operational tasks but also contributes to improved resource management and cost efficiency.

Clonetab has many options to meet the needs of each site. Although Clonetab's core features will suffice for most site requirements, Clonetab also offers infrastructure to allow you to add custom steps to make it more flexible to meet your specific needs. Clonetab base module for Oracle Databases, eBusiness Suite, and PeopleSoft is available. Normal shell scripts used to perform refreshes can leave sensitive passwords in flat file. They may not have an audit trail to track who does refreshes and for which purpose. This makes it difficult to support these scripts, especially if the person who created them leaves the organization. Clonetab can be used to automate refreshes. Clonetab's features, such as pre, post and random scripts, target instances retention options like dblinks, concurrent processes, and appltop binary copying, allow users to automate most of their refresh steps. These steps can be done once. The tasks can then be scheduled.
