It’s easy to say that cloud computing benefits people who use it. The idea is that what is this benefit really? Usually the advantages focusing on us are for end-users’ groups. As noted previously, the biggest advantage for any end user is that Cloud Computing can only be used when you need it (Consumer E-2008). It’s your system as a pay. The question is: why is it actually the benefit? To start with a user organization, no physical room is required for all hardware to install. In addition, there are no maintenance costs for all hardware (WATCH 2009).
Apart from hardware that is the applications that provide benefits. Cloud is full of applications that are ready to use, and the data used in this application is always available accessible anywhere around the world (Vacancola 2009).
A SLA (Service Level Agreement) guarantees that quality measures are known before entering the cloud. It is essential for SLA users and may be better when buying an organization by itself all the difficult and software.
Not only direct advantage, but the importance is that the databases are usually placed on strategic selective places that reduce cost of maintenance. Think of low salary countries (Vacancola 2009).
Advantages of more focused on cloud users become more concrete. As it is clear now, scholarship is one of the major benefits. When an organization is expecting a peak in its use, they only get more IT services from the cloud. It’s also her beauty, it’s very easy. Since large organizations have invested in cloud computing, users can expect a specific degree security (wit 2010) to users.
Cloud computing provides a combination of economic and performance benefits in this way. The economic benefit is to apply when the costs require additional IT services, and it is about the benefits of performance. Extra performance can be achieved when necessary, and can improve the performance of an organization directly.
With the understanding of cloud computing, we can see some similarities with other technologies. This paragraph is about explaining what cloud computing is not, and what are the differences with similar technology? Most of these technologies are larger than cloud computing and are more familiar with the audience, so it is important to make a difference between cloud computing.
Autonomous computing systems are the first to meet cloud computing. This computing format is different in different ways. The purpose of autonomous computing is to provide system with autonomous work (White 2004). That means they have to be able to manage themselves. They have to fix and fix themselves. It’s like cloud computing because it also contains large computer systems that lead to advanced guidance from humans.
The difference between cloud computing and grid computing is much better, but it’s easy to explain. Grid Computing focuses on massively while cloud computing offers both small and large services. Grid Computing usually provides continuous high performance, and (as it is necessary, when performing large computing of cloud computing, it will provide its performance.
Compared with each other’s main frame; the difference can be clear with an important frame, but there is similar equality. A central frame can be seen as a cloud. Although it is clear that a central frame provides access to employees in a larger organization and the main frame is completely central. This cloud is different with computing, as it is also performance. Mainframes provide continuous high efficiency and cloud computing only when necessary (Armbrust et al 2009).
Comparison-friendly neighbors have also been developed with competition. This is because there is a full cloud of users who are both “client” and “server” (Steve 2002). This is also the difference. In Cloud Computing clients, themselves do not work as a service provider.
The last comparison on which is discussed is compared to the individual computing service. The course is based on the cloud computing service. But service-oriented computing focuses on high-speed technologies. Cloud computing focuses on delivering computing instead of techniques, as mentioned earlier several times.
