Guide to my recent research on computing appliances
My recent flurry of research into computing appliances was spurred by a column I just submitted to Network World. In that column there’s a URL – pointing to this post – promising a guide to more details on that research. Thus, here’s a set of links to my posts of the past few months on computing appliances, both here and on DBMS2.
Half or more of the computing appliance vendors I’ve looked into follow very similar hardware strategies: They use mainly standard parts; they include uncommon but off-the-shelf networking (and sometimes encryption) accelerators; and they of course optimize the mix of those parts and general hardware architecture as well. (EDIT: I actually gave names to three strategies — even if they were just “Type 0”, “Type 1”, and “Type 2” — in this overview of data warehouse appliance vendors. And in another post I considered arguments about whether one would want a data warehouse appliance at all.) Examples I’ve posted about recently include – and I quote the forthcoming column – “DATallegro and Teradata (data warehousing), Cast Iron Systems (data integration), Barracuda Networks (security/antispam), Blue Coat Systems (networking), and Juniper (security and networking).” (ANOTHER EDIT: But I think DATAllegro’s strategy has changed.)
By way of contrast, there’s also a group whose stance is more along “hardware/schmardware” lines. Sendio and Proofpoint (in most cases) don’t really do anything special at all in their boxes; what’s more, Proofpoint actually has significant software-only deployments over VMware’s virtualization layer. Kognitio and Greenplum think their software-only data warehouse offerings are appliance-equivalents too; indeed, Greenplum’s software is sold mainly bundled with Sun hardware (to the extent it’s sold at all), and Kognitio is hinting at an appliance-like offering for competitive reasons as well. Check Point Software plays both sides of the field; it offers its own kind of “virtual appliance,” but also gets many of its sales through appliance vendors. Its most interesting such partner, if not its biggest, is Crossbeam Systems, which in my opinion may very well represent the future of appliance technology.
Proofpoint and VMware – an apparently non-trivial virtual appliance success story
I talked with Proofpoint today, and got a more positive view about VMware’s virtual appliance strategy than I’ve gotten from other appliance vendors. They cite over 500 downloads in the past couple of months, of which a significant fraction have turned into actual sales. Specific deployment scenarios they mentioned include:
- Demo (of course).
- Tweak, test, deploy – between patches and new anti-spam rulesets, Proofpoint users seem to have a rapid change/test/deploy cycle. Virtualization makes it possible to do that without having multiple copies of an appliance.
- Disaster recovery – this seems to be a big one.
- “Surges” – depending on what the bad guys are doing, one’s need for anti-spam servers can go up and down in a hurry. Virtualization makes it easy to respond.
