networks, but we never seem to have access to the document we need, when and where we need it. It is apparent that we need highly
intelligent indexing routines, so the computational implications of cloud systems do seem to offer some hope. That means we can run complex search programs in the same internet space where the shared files reside.
Moving to the Cloud The second step in migrating to the
cloud is often to move the traditional data-processing system per se. All of the cloud companies men-
tioned above offer the ability to configure your cloud virtual server so that it appears to be whatever kind of computer you may need it to be. If your existing in-house server is Microsoft-based, then you can have a cloud virtual server configured to run the appropriate Microsoft operating system. Likewise, if your operational system is Linux- based, your virtual server can be Linux. Typically, when traditional da-
ta-processing systems are migrated to the cloud, certain modifications are required. Users connecting to in- house servers do so using terminals (or PCs acting like terminals). Access to internet sites is, of course,
more often carried out using brows- ers like Internet Explorer, Safari or Chrome. While these user interface differences need to be addressed, traditional systems can usually be mi- grated to the cloud, without changing database structures, business logic, or even many reporting programs. All of our existing clients have
made the migration, and the last to do so completed it in 2002. We are more than happy to share our expe- riences to all STN subscribers free of charge. ●
