Operating System Services For Wide-Area Applications
This talk examines system support issues for wide-area applications
given the opportunity posed by remotely programmable resources.
Experience with the Network of Workstations project has helped to
identify four key requirements as applications migrate from the local
area out across the wide area: (i) naming of remote, potentially
migrating objects, (ii) coherent access to global data, (iii) safe
execution of remote programs, and (iv) secure, authenticated access to
global resources. This talk describes the design and implementation
of WebOS, a unified set of system services designed to simplify
application development and to more efficiently utilize wide-area
resources. One lesson from the work is that wide-area applications
require many of the same abstractions as local-area or campus-wide
computing infrastructures.
