Calista Technologies

Calista Technologies was a desktop and GPU virtualization startup founded in 2006 in San Jose, California by Neal Margulis, backed by Lightspeed Venture Partners, Greylock, and Western Technology Investment. Its software improved the user experience of 3-D and multimedia delivery for virtualized desktop deployments and server-hosted applications running on Windows Server Terminal Services (Remote Desktop). Microsoft acquired the company in 2008 and folded its GPU-virtualization technology into RemoteFX. The company is defunct and publishes no live developer, documentation, or API surface; its former domain (calistatechnologies.com) is now a parked domain listed for sale.

Calista Technologies is profiled on the APIs.io network. Tagged areas include Company, Virtualization, Desktop Virtualization, GPU, and Remote Desktop.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/calista-technologies: open an issue to ask a question, or submit a pull request to add artifacts.
