Originally, it was the only form of construction and operation of an information system, so a name representing itself was not required.However, from the late 1990s to the early 2000sBroadband internet connectionAs a method of outsourcing the construction and maintenance of information equipment due to the spread of information, external devices connected to the InternetServer farmAs a resource, depending on the scale of your company's information systemon-demandIt is now possible to realize a new operation form to be utilized in.This conceptSaaS,PaaSIt was commercialized as, and since 2006Cloud computingAs the name was proposed and permeated into society, to distinguish the conventional operation form that independently manages resources from those on-demand forms.Retro NimAs a result, the word "on-premises" has been commonly used since around 2010.

The advantages of using cloud computing services include low initial costs and fixed maintenance and operation costs, but on the other hand, other factors such as reaction speed, security, customizability, and visibility. You need to consider the aspect.In addition, when the billing system is on-demand, that is, a pay-as-you-go system, it becomes necessary to determine economic efficiency based on business growth.On-premises is often preferred depending on the business model, such as the financial and defense industries.Therefore, in actual operation, it is not a simple transition to on-demand, but the view that users need to cooperate with the cloud and on-premises while considering various factors.^[2]Analysts also predict that latecomers in Japan will focus on business models that meet such needs.^[3]..The transition from on-premises to full cloud continues because it's so easy that you don't have to buy hardware and install it in-house.
