Infrastructure as a Service, Platform as a Service and Software as a Service
The services offered by the hardware and systems software over the Internet are referred to as software as a service. Software as a service utilizes a cloud, which is a data center that utilizes the hardware and software system. The services provided can be for public consumption or for private consumption. The public services are also known as public clouds, for example the “pay as you go” plan. The private services are known as internal services and can be utilized by a company for storing data.
The products gained from services offered by software as a system are referred to as platform as a service or infrastructure as a service: the two phrases are sometimes used interchangeably. These are also known as cloud users since cloud computing is as a result of software as a system. Software as a service is a result of a cloud and the other two components dependent on it. It is a precursor to platform as a service or infrastructure as a service. It seems that the last two cannot operate without the software as a service.

Large Capital Outlays in Hardware
Digital technology is improving as the years progress and globalization spreads. It is quite possible to find machines that have replaced human beings in many organizations. Machines are preferred due to many advantages including the fact that they are faster. A good example in this case is cloud computing, which utilizes the normal computers and software to make work easier. An example is given where during demand outbursts, cloud computing can offer equipment that can handle such spikes in the market. If the same services were to be provided by human beings, then it would take longer and become more costly.
Initially, large capital outlays would be required to invest in better hardware. However, cloud computing has offered a cheaper way of doing this. Apparently, cloud computing has provided more efficient ways of performing work such as cost analysis. This efficiency means that developers of innovative ideas can utilize cloud computing instead of investing large capital outlays in other hardware.
Cloud Computing Economics
Cloud computing is viewed as an economic choice for many companies because of its benefits over conventional hosting. First, cloud computing seems to save time and cost as well. Cloud computing is a way, whereby companies can get machines for renting when and if such services are needed. This advantage has improved the demand, especially due to cost saving.
Moreover, sometimes the duration of demand for a certain service is unforeseeable. For most companies cloud computing offers the best choice when it comes to such cases. An example is given where a web may lose its popularity over a certain period. In such a case, batch analysts can use cloud computing to clear computations much faster than the conventional services. The economic premise here is based on the cost analysis and the short time that cloud computing offers to make these calculations. Companies can save on time and cost.
Cloud computing has the benefits of elasticity to any company, which is also the reason why it is an economic choice. It is possible to add or remove resources from a single computer in a database using the shortest time possible. As such, the workload is reduced and, thus, companies can save on outsourcing labor. The short time it takes to acquire cloud computing ensuring that companies can provide required services during demand outbursts. This ensures customer loyalty, thus cloud computing is an economic choice.
