VMmanager

VMmanager is a platform for automation of virtual infrastructure leasing and creation of high-availability virtual environments. It handles both hardware and container virtualization, isolates and abstracts virtual infrastructure from physical hardware, and streamlines cloud hosting service provisioning. The platform automates the delivery of IaaS VPS and SaaS-based services to hosting providers’ clients. A built‑in library of over 60 ready‑to‑deploy operating system images and application stacks enables rapid VM deployment with pre‑configured software. Integrated IP address management (IPAM) simplifies network configuration, while IP‑Fabric based on BGP allows providers to create isolated private networks and conserve public IP addresses. Additional services such as extra IPs, VXLAN subnets, and data protection tools can be automatically provisioned through the same unified workflow. A self‑service client portal lets end users independently reboot machines, monitor performance, manage IP addresses, and establish remote connections — all without involving support staff. The underlying architecture is built to scale: a single installation supports over 25,000 virtual machines and 350+ physical nodes in a cluster. High availability is ensured through HA clusters, live migration capabilities, automatic load balancing (DRS), and built‑in backup functionality. The platform also supports GPU passthrough and virtual GPU (vGPU) for graphics‑intensive workloads. Designed with an API‑first approach, VMmanager integrates into existing toolchains and billing systems without locking providers into a single vendor. This allows businesses to scale their virtual infrastructure on demand without switching platforms.

Verge.io

VergeOS by VergeIO is a Private Cloud Operating System (Private Cloud OS) designed to replace legacy virtualization stacks and assist organizations in modernizing their infrastructure while transitioning away from platforms like VMware. This innovative solution integrates compute, storage, networking, and data protection capabilities into a single software platform, allowing it to run directly on standard x86 servers. By consolidating these functionalities, VergeOS simplifies the management of IT resources and enhances operational efficiency. Traditional virtualization environments often rely on layered architectures, where separate components handle compute, storage, and networking, leading to increased complexity and costs. This fragmentation can hinder the modernization efforts of organizations, especially those seeking alternatives to VMware. By replacing only the hypervisor, companies may still encounter operational challenges and fail to realize the full benefits of an integrated system. VergeOS addresses these issues by offering a unified Private Cloud OS that incorporates all necessary functionalities within a single architecture. At the heart of VergeOS is its enterprise-grade server virtualization, which enables organizations to run virtual machines across clusters of standard hardware. The built-in storage virtualization aggregates internal disks from servers into a resilient distributed storage layer, eliminating the need for external storage area networks (SAN) while still supporting FC attached SANs if required. Additionally, the integrated software-defined networking capabilities provide essential services such as segmentation, routing, and automation without the need for separate networking platforms, thereby streamlining operations. The unified design of VergeOS not only enhances infrastructure efficiency but also allows organizations to maximize their existing resources. By reducing overhead and simplifying operations, more CPU, memory, and storage capacity can be allocated to actual workloads rather than maintaining disparate infrastructure components. For organizations looking to exit VMware, VergeOS facilitates migration with built in tools, without necessitating a complete data center overhaul. Existing servers, regardless of vendor or generation, can often be reused, allowing for modernization without incurring the costs of a hardware refresh. Furthermore, VergeOS includes integrated data protection features such as snapshots, replication, and disaster recovery orchestration, which eliminates the need for separate backup solutions. This consolidation not only reduces costs but also enhances visibility and recovery speed for IT teams, resulting in a more predictable environment for automation and infrastructure management. As organizations strive for cloud-like agility within their data centers, VergeOS provides a practical and sustainable alternative, transforming traditional virtualized infrastructure into a modern private cloud platform.
