A thin client is a lightweight computer that is purpose-built for remoting into a server (typically cloud or desktop virtualization environments). It depends heavily on another computer (its server) to fulfill its computational roles. This is different from a conventional desktop PC (fat client),
which is a computer designed to take on these roles by itself. The
specific roles assumed by the server may vary, from hosting a shared set
of virtualized applications, a shared desktop stack or virtual desktop,
to data processing and file storage on the client's or user's behalf.

Software as a service
Software as a service (SaaS; pronounced /sæs/[1]) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted.[2][3] It is sometimes referred to as "on-demand software",[4] and was formerly referred to as "software plus services" by Microsoft.[5] SaaS is typically accessed by users using a thin client via a web browser.
SaaS has become a common delivery model for many business applications,
including office and messaging software, payroll processing software,
DBMS software, management software, CAD software, development software, gamification, virtualization,[4] accounting, collaboration, customer relationship management (CRM), management information systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, content management (CM), and service desk management.[6] SaaS has been incorporated into the strategy of nearly all leading enterprise software companies.[citation needed][7][8]
According to a Gartner Group estimate, SaaS sales in 2010 reached $10 billion and were projected to increase to $12.1 billion in 2011, up 20.7% from 2010.[9] Gartner Group estimates that SaaS revenue will be more than double its 2010 numbers by 2015 and reach a projected $21.3 billion. Customer relationship management (CRM) continues to be the largest market for SaaS. SaaS revenue within the CRM market was forecast to reach $3.8 billion in 2011, up from $3.2 billion in 2010.[10]
