Studija iz publikacije Communications of the ACM, koju je napisala grupa istraživača iz RISELab (Real-Time Intelligence Secure Explainable Systems Lab) sa UC Berkeley. Pojedini autori su 2010. godine počeli da se bave fenomenom cloud computing-a, a sada se bave analizom postojećih trendova i predviđaju novu fazu rada u oblaku.
The first phase mainly simplified system administration by making it easier to configure and manage computing infrastructure, primarily through the use of virtual servers and networks carved out from massive multi-tenant data centers. This second phase hides the servers by providing programming abstractions for application builders that simplify cloud development, making cloud software easier to write. Stated briefly, the target of the first phase was system administrators and the second is programmers. This change requires cloud providers to take over many of the operational responsibilities needed to run applications well.
