As of 2007, centralized computing is now coming back into fashion – to a certain extent. Cloud computing has had an important role in the return of centralized computing.<ref>{{Cite journal|last=Irion|first=Kristina|date=2012-12|title=Government Cloud Computing and National Data Sovereignty|url=http://dx.doi.org/10.1002/poi3.10|journal=Policy & Internet|volume=4|issue=3-4|pages=40–71|doi=10.1002/poi3.10|issn=1944-2866}}</ref>. [[Thin client]]s have been used for many years by businesses to reduce [[total cost of ownership]], while [[web application]]s are becoming more popular because they can potentially be used on many types of computing device without any need for software installation. Already, however, there are signs that the pendulum is swinging back again, away from pure centralization, as [[thin client]] devices become more like [[diskless workstation]]s due to increased computing power, and web applications start to do more processing on the client side, with technologies such as [[AJAX]] and [[rich client]]s.

In addition, [[Mainframe computer|mainframe]]s are still being used for some mission-critical applications, such as payroll, or for processing day-to-day account transactions in banks. These mainframes will typically be accessed either using [[terminal emulator]]s (real terminal devices are not used much any more) or via modern front-ends such as [[web application]]s – or (in the case of automated access) [[Communications protocol|protocols]] such as [[web service]]s protocols.
