Overview

OnApp is a cloud server management platform vendor headquartered in London, UK, founded in 2002. Rather than selling hosting directly to end users, OnApp provides hosting providers and data center operators with an IaaS orchestration platform to quickly build and run their own public cloud, private cloud, and edge computing infrastructure.

The core product is cloud management platform software (IaaS orchestration) that unifies compute, storage, and network resources and offers white-label delivery, letting hosting providers launch cloud services under their own brand. In 2019 OnApp was acquired by Virtuozzo, and its website now redirects to virtuozzo.com as the product continues to evolve within the Virtuozzo ecosystem. See 2026 cloud market report for industry context.

Key Strengths

  • Focus on hosting providers: founded in London, UK, in 2002 and dedicated to IaaS orchestration, with the official site claiming 2000+ hosting provider customers.
  • White-label delivery: cloud servers can be delivered to end customers under the provider's own brand, with 2000+ hosting providers reportedly using this model.
  • Edge and CDN capability: bundled OnApp CDN edge delivery (90+ PoPs, official claim) adds CDN acceleration.
  • Ecosystem evolution: acquired by Virtuozzo in 2019, with virtualization and cloud capabilities continuing to grow.

Product Ecosystem

OnApp Cloud (IaaS Orchestration Platform)

The core product for hosting providers: virtual machine lifecycle management, resource pool scheduling, billing, and a customer self-service portal, building public and private clouds on KVM-based virtualization. It suits server selection for teams that need large-scale cloud resource management.

OnApp CDN

An edge delivery service that caches static assets across global points of presence, pairing with the cloud platform to give provider customers acceleration; see CDN acceleration basics.

Virtuozzo Ecosystem Integration

After the acquisition, OnApp's capabilities are integrated with the Virtuozzo container/virtualization platform, giving hosting providers a full-stack path from containers to cloud.

Limitations

  • Not an end-user product: built for hosting providers, so regular users cannot buy directly and must go through platform-based providers.
  • Complex deployment: requires virtualization, storage, and networking investment, with a high implementation and operations bar for teams.
  • Brand integration changes: after the Virtuozzo acquisition, standalone brand operations have faded and the roadmap centers on Virtuozzo, so track roadmap changes.
  • Opaque costs: licensing and implementation fees require sales discussions with no public pricing, so budget early.

Use Cases

  • Hosting providers building their own cloud (★★★★★): quickly launch a branded public/private cloud and sell it.
  • Data center operators (★★★★): use orchestration to monetize idle resources with cloud and CDN services.
  • White-label cloud services (★★★★): deliver cloud servers under your own brand without building from scratch.
  • Edge and CDN value-add (★★★★): layer OnApp CDN to offer acceleration.
  • Individuals and SMBs (★): not sold directly; choose a cloud server provider instead.

FAQ

  • How is OnApp different from a regular cloud provider? OnApp is cloud management platform software for hosting providers, not an end-user host; end users buy cloud servers from providers running the OnApp platform, see cloud server configuration guide.

  • Can individuals use OnApp? Not directly. For cloud servers, individuals and SMBs can compare terminal providers in cloud server pricing.

  • Who owns OnApp now? It was acquired by Virtuozzo in 2019, and onapp.com now redirects to virtuozzo.com as the product joins the Virtuozzo ecosystem, see cloud computing trend analysis.

  • What capabilities does OnApp offer? IaaS orchestration, white-label cloud, resource scheduling, billing portal, and OnApp CDN edge delivery; see cloud market report.

  • Is deployment costly? It requires virtualization and network infrastructure and paid licensing through sales contact, so hosting providers with engineering teams should evaluate carefully, see enterprise server budget planning.
