Architecture and Challenges in Computing

The report will discuss in detail about the concept of cloud computing and how it impacts the business in a different manner these days. Therefore, in the process of understanding the power of cloud computing, it is important to have more clarity about streamlining the processes of IT which make the whole process more convenient. However, it is important to understand that it is not easier to rush into the whole process (Aljabre, 2012). Right before, making the changes, it is also crucial to ask some relevant questions and also understand the pros and cons of the process. Cloud computing is being used like never before, and there are organizations of every kind and sizes that adapt the newer technology which helps business to work in an efficient manner. Some industry-based experts who also believe that the system will only continue to develop even further in coming future. The concept of cloud computing is also very advantageous for some mid-size as well as big organizations. As discussed, there are certain disadvantages as well of the process with the opinion to assist many establishments completely understand the process in a proper manner (Aljabre, 2012). There is the detailed discussion of advantages as well as disadvantages of cloud computing with an opinion to assist these kinds of establishments by having complete clarity about the concept of cloud computing. The objective of the report is to understand the advantages and disadvantages of cloud computing clearly. Since cloud computing comes with some advantages for the businesses however companies cannot completely depend on it, and there are some disadvantages as well, and it is crucial to completely understand the concept of business as well as technology which is based on service providers. The concept of cloud computing can be defined as the providing on-demand resources related to computing, and it is also important to understand that everything from some applications to a different base of data can be applied here on the internet. This is done with the help of on a pay for usage basis. Companies like Microsoft and the Amazon are some of the biggest names in providing cloud computing system and also offer the same kind of definition. This also means the concept can utilize the internet in the place of a hard drive in the computer to access the remote servers and also some effective processors that have the ability to perform an intensive storage functions over the internet (Subashini and Kavitha, 2011). There are different kinds of clod computing programs discussed in detail below: Infrastructure based service: this concept consists of the basic blocks that help in building cloud computing and information technology structure as well as also provides access to a number of networking based characteristics. It also consists of data based storage spaces as well as a number of computers. The system also provides companies with high flexibility level and overall control on management over a number of resources in IT, and it is also quite same to the present resources of IT that any department or developer can be familiar with at the present time. Platform as a main service: this kind of system eliminates the requirement for companies to manage the basic level of infrastructure that usually based on operating systems and hardware. Also, it also permits companies to pay attention to the process of deployment and also manage the application in an effective manner (Marston et al., 2011). This further assists them to be more effective as it doesn't require to take any tension about the resource based procurement process, or planning of the capacity, maintenance of software or any other different and heavy lifting which requires involvement in running the overall application. Software as the main service: this can be treated as a finished product that is managed by a number of different service providers. In many cases, it is important to refer the software as the main service that can be referred to software as the main service provider and it can refer to the end-user based applications. With this kind offers there is no requirement to think about how services can be maintained as well as the overall infrastructure can be properly managed. It is important that users only require basing whole research on the specific piece of software. There are some common examples of the system like website based emails. Here these emails are received and further sent without properly users that can manage characteristic in addition to the product and also maintain different servers as well as operating systems that is based on any program (Marston et al., 2011). Cover over data: while running any application that one can share the photographs with millions of mobile based users and also provide support to the critical kind of functions associated with the business. At the same time, the cloud providers are based on providing a rapid access towards flexible as well as low cost based IT kind of resources. The marketplace online and another kind of cloud provider said that the users usually don't need to make large investments in different kinds of hardware and also provide a lot of time on the heavy lifting of managing the hardware in a perfect manner. Rather, the concept of computing can be treated as a provision which is of the right kind and for the right size of computing the resources which require the power in the new as well as bright ideas that function in many IT departments (Han et al., 2011). When the cloud computing system is used in the right manner and to some extent, it is important while working with information in the cloud can be very profitable for every kind of business. Following are some of the main advantages of this system: Cost based efficiency: the concept of cloud computing is the most cost efficient system in using, maintaining and also upgrading process. While dealing with traditional desktop based software costs, companies spent a lot, and it is associated with finance. Also, the licensing based fees add different users, and this can prove to be quite expensive for the setting up in the concerned department. On the other hand, the cloud is present at an affordable rate and therefore, can lower the expenses of IT in significant manner. Also, there are some one-time payments where pay as one go and another kind of scalable point present that make it further reasonable for the organization (Han et al., 2011). Unlimited storage: storing the data in the cloud provides a lot of storage capacity. Therefore, one needs to worry about completely run out of the storage space or raising the present storage space and its overall availability. Recovery and backup: - all the data is stored in the cloud, and this is why proper backup and restoration of the same is easier than storing the similar kind of physical devices. Also, many cloud-based services providers are normally competent by nature to handle the overall recovery of data in an efficient manner. Automatic integration of software: in cloud computing, software based integration is normally associated with something which happens automatically. This also means that one need to some extra efforts to change and also integrate the applications as per the preference of the customers. These kinds of aspect generally take care of itself and not just that, the concept of cloud computing permits the company to customize the options with ease accordingly. This way, the company can handpick different services and software based applications that one can think of and it also suits the specific enterprise in a proper manner (Low et al., 2011). Comfortable access to data: - once companies get to register to the system, it can easily access the data from any part of the world where there is a proper internet connection. This feature will help in going beyond the present time zone and geographic based locations and related issues. Rapid deployment: Lastly, the process of cloud computing provides different advantages of rapid deployment. When the company goes for this method of operations, the entire system can be completely functional very quickly. At the same time, the time taken here will also depend on the same type of technology that company required for the business (Low et al., 2011). Despite of all above disadvantages, the concept of cloud computing also has some disadvantages which are discussed in detail below: Issues in technical aspect: the fact that information on the cloud can be accessed at any point of time and from any part of the world. However, at times the systems can create a lot of problems. Companies should be well aware of the fact that the technology is always based on many technical problems. In fact, the best kinds of service providers function into kinds of trouble and despite keeping some very high standards for maintaining it properly. The company also must have a strong internet connection to get logged onto a different kind of server at all possible times. The concept of cloud computing is an important characteristic of any big scale deployment. It can be taken as a method which leads a much tech-based organization to offer companies and people their personal space to store and also use the growing pile of information since some smart machines gather it. It is important to understand that not everything about storing information online can be an advantage when it is compared with older hardware ways (Janssen and Joha, 2011). Security based on a cloud: the other important issue while using the cloud technology is that there number of security-based challenges. Right before applying this technology; companies must understand that one will be completely surrendering all the sensitive information of the company to an outsider. This can be a great risk for the company. Therefore, companies require being completely sure that they choose the most trusted service provider who will protect the information correctly (Janssen and Joha, 2011). Attacks possibility: saving the data in the cloud can make the companies in the most vulnerable situation and can also impact many external based hacks like attacks or threats. It is important to understand that there is nothing on the internet which is completely safe and this is why there is always a risk of hacking of sensitive data. There are some disadvantages discussed above, and the best kind of cloud provider can claim complete immunity towards service based outages. Some cloud computing systems that are based on the internet and also mean the overall access is based on the strong internet connection. Therefore, it is important to understand that whether the business can absorb a continuous bout based on constant slowdowns. Also, there are some incidences in past where service provider like DropBox faced the similar situation for the longest period which is two days. It is very important to consider two crucial points like business based processes that can be halted if any service provider goes completely down and the internet connection which must be strong otherwise all business based application will also drop offline (Fernando et al., 2013).   The technology of cloud computing in the present time has become very crucial for every business users, and it further plans to move ahead and be more advanced. The kind of cloud has addressed many needs of organizations. This can be in public based cloud or private based cloud and in some case a hybrid kind of cloud where every category is sufficient to apply it effectively. The concept of cloud computing is that the business answers that every company can utilize properly. There are so many pros as well as cons of cloud computing, and it is important to be very careful while applying in business (Gà ©czy et al., 2011). Like every other process, the concept of cloud computing has its pros as well as cons. The technology can also prove to be a huge asset for the organization, and it can also cause some serious harm or threats if not executed in a proper manner. The concept is not evolving in a way it never happened before, and there are companies in all kind of shapes and sizes that can adapt to new technology. There are industry experts that have a belief that this fashion will only develop and grow further in future (Gai and Li, 2012).   This is why the concept of cloud computing is very beneficial for so many and different kinds of companies. Of course, as discussed it comes with number disadvantages specifically for small businesses.   In the present time, with proper planning and significant precautions, the disadvantages of the concept can be reduced tremendously. It is also true that the concept has transformed the business world completely and the advantages can easily outweigh the disadvantages of cloud computing. Minimum cost, as well as easy access along with proper data backup and centralization as well as security and rapid testing, are becoming more and more relevant (Jadeja, and Modi, 2012).
