Ring Any Bells?• You manage a Web service or create
departmental Web pages• Your job was fun once, but now it's difficult to
keep on top the job• You need extra resources, but can’t get them• Your good Unix systems staff have left for $$$$• There is a software solution, but it's expensive• You tried to install the 14 day evaluation version,
but couldn't get it to work• When you eventually got it to work, your PC
wasn't powerful enough to run it• You can't afford an upgrade to your PC

An Answer To The Webmaster's Prayer?A solution may be available:
• A solution which is free (in many cases)• A solution which requires no software installation• A solution which requires no investment in
hardware• A solution which exploits the network – remember
Sun’s slogan “The network is the computer”
The solution is deployment of externally-hosted Web services
Sounds great? But will it mean outsourcing your IT department?

What Do We Mean?Remember HTML Validation services:
• Enter a URL into a Web form and check it validates
• Add an image if your page is valid HTML
• Link the page to the validation for on-the-fly validation - an externally-hosted web service
Another example is the hit counterAnother example is the hit counter

What edge of this spectrum are you closest to?
Sorry I'm indecisive.I can't decide.
Your View So Far
Sounds great, no software to install, available for free. What else can be done in this way?
No way! I don't want to be reliant on anyone else. Besides, I'll be out of a job if this idea takes off – this is out-sourcing.

IssuesMany externally-hosted web services are available, but:
• What about the dependencies of the network(s)?• What about the reliance of the third-party? Will
the company stay in business?• The interface isn't as rich as desktop applications• If the service is funded by advertising revenue,
with use contravene the AUPs and guidelines?• Will large-scale use of such services generate
large network bills?• Is my data secure and private?• Is my data reusable and available in an open
format?• Is is sensible for a mission-critical service?

RDN IncludeThe Resource Discovery Network Centre (RDNC) coordinates the work of RDN hubs, such as SOSIG, EEVL, BIOME, etc. Institutions may be reluctant to link to hubs as they want users to stay on the University Web site.
The RDNC is developing the RDN-I (Include) service to give the appearance that the hub is located within the institution.

What About The Users?
"I use the external services because the University doesn't allow me access to install on the server and because it doesn't make any appropriate tools available."
Tom Wilson, Department of Information Studies,
University of Sheffield
"Our search facility is currently hosted by atomz.com , some calendering by Yahoo!, so I'm increasingly drawn to externally hosted solutions... more time to catch up on other, more pressing work, until they all stop working."
Ian Usher, Webmonger, Department of Geography, UCLAt one university 60% of UGs arrived with a HotMail account, which they used in preference to the University email account.
• Should the university support use of HotMail?• Can they afford not to?• What will happen when they arrive with a calendar service?

ASP Application Service Providers (ASP):
• Commercial sector already moving in this direction
• Sun promote access to StarOffice across network in preference to MS Office on local PC
• Futurelink.net renting MS Office across network for £79 / month
Do I need an ASP?Useful if:
• You don’t have any in-house IT staff
• You need software for a fixed time
• You want your IT staff to concentrate on “competitive edge” projects
• You’re a small organisation with remote sites to support
• You want to try out software without buying it
• You prefer monthly rental to upfront hardware / software costs

Conclusions
Externally hosted web services:• Are available in many different areas• Arguments against their use (reliability, privacy, trust,
performance) should diminish as they mature• Their usability will improve as W3C developments
(DOM, XHTML, SVG) become more available• Your user community will use them (are using them)
in any case• Of particular interest to the public sector community? • Will we see a move towards use of Application
Service Providers (ASPs)? • A valuable resource for the Web Manager
