Deployment via a Physical Support
This deployment option is still quite popular and attractive for developers and marketing staff,
given the low costs of such deployment supports and the ability to reach otherwise inaccessible
customers. In Chapter 7, we will see a concrete example of such an option. What is interesting
to note here is that often such an alternative is used as a way to distribute software rather than
a complete deployment means. Once installed, the software usually takes advantage of an
existing Web connection for further deployment services. Also, JNLP and other advanced
deployment tools can be used for this type of support. This option is quite attractive when
deployment via a CD-ROM is part of a more general deployment strategy, as discussed in the
next case.
Multiple Deployment
Of course, the deployment strategies previously described can be used together, obtaining the
advantages of all the single deployment techniques. A common way to proceed is to package
the application for Internet deployment (thus covering both the intranet and Web channels) and
then packaging it on a CD-ROM for physical distribution. In this case, the standard general-
purpose deployment means such as JNLP and some third-party deployment tools are best
