Different SPI Models of Cloud Computing Case Study - 1

Different SPI Models of Cloud Computing - Case Study Example Cloud computing is actually a colloquial expression that refers to an array of varying types of computing concepts that consist a large number of computers interconnected to each other by means of an actual, simultaneous communication like the Internet (Carroll et al., 2012). Also, cloud computing is a model that is used to allow pervasive, global, and convenient network access to a common collection of configurable computing resources such as networks and servers (Mell & Grance, 2011). Essentially, the objective of cloud computing is to maximize shared resources. This has been carried out by sharing services and resources that are made available on the World Wide Web. How? At the root of cloud computing is a deeper concept of combined infrastructure and shared services. So, why the thought of using clouds as part of the phrase? Cloud computing allows shared services including servers, not actual serves but virtual servers which are interconnected to each other using the internet. These servers do not really exist in actuality; hence, they can be moved around or expanded while the end-user is not being affected at all – similar to a cloud. Cloud computing has different SPI models and each of them has a specific use. But first, let us learn about what SPI means. SPI is an acronym that refers to conventional cloud computing models. SPI stands for the following: S is for Software as a Service (SaaS); P is for Platform as a Service (PaaS), and I is for Infrastructure as a Service (IaaS). SaaS is specifically intended for the end-users, which are transmitted over the internet. PaaS is a collection of means or instruments meant for coding and setting up applications quickly and efficiently. And lastly, IaaS simply pertains to the hardware and software that make everything work effectively. These include servers, networks, operating systems, etc. (Mell & Grance, 2011). SaaS is normally end-user applications that are being delivered by means of the internet.  There is no need for installation as long as a browser and a connection to the internet are set.
