Citrix

Eighteen years of published application delivery on the municipal estate, five platform generations — and the virtual desktop product the same estate decided not to buy.

Product lines and other names: MetaFrame, Presentation Server, XenApp, XenDesktop, NetScaler, StoreFront, Citrix Secure Gateway, Web Interface

Left to right is time. Each row is one of the 6 disciplines Citrix carried, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that named this manufacturer is counted, so this is the shape of what it carried rather than of the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

MetaFrame and Presentation Server from 2005, the 4.5 farm, XenApp 7.6 into production, XenApp 7.15 long-term service release, then a rebuild onto Windows Server 2019. The external path moved with it: Citrix Secure Gateway with Web Interface, later NetScaler Gateway fronting load-balanced StoreFront in the demilitarized zone.

XenDesktop appears here too, and it is the counter-example. It was piloted in 2011 on a dedicated subnet with the firewall policy staged so the whole thing could be backed out cleanly, and decommissioned by change order inside eighteen months. Named on this page because it was operated, not because it was adopted.

Where it appears

Declared on each entry rather than listed here, so this page cannot drift from the work it describes. What each entry named is quoted as it stands, with how much of that project rested on it and what stands behind the claim beside it. The first of those drives the height of the surface above.
