Advantages And Drawbacks Of Cloud Computing Essay.

Discuss about the Literature Review of Cloud Computing.

The concept of Cloud computing has emerged as the revolution which can be implemented by the business organizations for the execution and attainment of the varied objectives and targets such as delivery of computing services to the connected servers and the networks, storing, safety and security of databases, networking. Cloud computing consists of the software and systems which can be utilized by the entities in a number of operations, analytics. Cloud providers are the name which has been accustomed to the institutions that provide these services and an amount or a kind of fees has been charged by the service providers which are based on the usage of the systems and the mechanisms. According to Baiju (2014) Cloud storage is the mechanism where the data is stored, backed, maintained and managed. It is a facility for the service users of storing their data and files online and after that they can access those files from any corner of the world. As per the survey it has been found out that more than 800 business corporations have gained competitive advantage by the adoption of this service. A number of small and large business corporations have been waiting since long for the systems like cloud. Despite the system has been proven advantageous for the business corporations many of the business corporations have confusion and a doubt regarding the adoption of this system for carrying out the operational activities and storing the confidential files. The below carried out research report has been presented by the Help-desk LLC and this research has been focused on defining the system and also determination of cloud computing. A brief description has been provided about the concept of Cloud computing. The concept has been considered as the same it was in earlier times with a slight change in the name has done. This concept has been found to be adopted and utilized by the entities from last many years. As per the research many of the business corporations are been observed who are making use of this mechanism. There is a server which is linked with a number of computers and desktops which are networked to the server. There is also another system which has been used and is known as hardware layer and which is also typically referred to as "the network," or "the information systems." The cloud system has minimized the need of networking in the offices at a greater extent. A numerous benefits are there which can be attained by the adoption of this system and from them one of the biggest aid is to the network as it can be easily accessible from anywhere and anyone one can have access to the Internet, this makes the company in running mode for 24/7. Also it can be accessed from any of the device or mechanism which can be made easily available– i.e. laptop, iPad®, mobile phone, etc.  The best suitable example is Google Docs.  This is one of the most common use of cloud computing service by an individual or a business entity i.e. this system will be made in use while submitting of the confidential and important documents to Google Docs via the Internet. Moreover there is another suitable example which can describe the functioning of this system; it can be used by average small business person. The owner of the small scale business won’t be having big investing amounts in the establishment of an in-house network and also the entire business operations should running for a short period of time. So here the service of cloud computing can be used as the expenses will be on the usage of the system and the service. The expenses are basically pay-as-you-go means as per the use and are also based on the amount of storage space and computing power that you use. The below mentioned are the elaborated advantages and drawbacks of cloud computing:

Most Economical Method

Most economical – Introduction of the cloud computing services has brought reduction or minimization in a number of expenses which were earlier incurred by the business organizations. The mechanism does not even require huge investments and heavy expenses to be spent by the entities on the establishment and setting up. The expenses are too low as the system does not involve any kind hardware’s, equipment and infrastructure to be fixed within. Also no expenditure is to be made for the installations of the desktops, laptops or some type of device to access the Internet (levelcloud. 2017). Moreover there are some of the expenses which are required to be spent on the implementation and maintenance of the private and the company’s own in-house networking and which is very minimum or low. The concept has to be recognized as a vital and significant one for many small scale business corporations too. But there are some expenses which are to be incurred while maintaining the in-house network. These expenses are enormous and it has also been observed that they are increasing day-by-day. Moreover there are other related costs and expenses which are essentially to be incurred by the corporation at the time of installation of the software and hardware upgrades and also the maintenance and providing training on the related topics to the employees. The above mentioned are the services and the responsibilities which are expected to be rendered and to be fulfilled by the service providers of the cloud systems and also the costs and the expenses are to be incurred by them only. Renting vs Owning is the concept which can be referred for developing an understanding which is related to the concept of expenses computing services. The service providers of the cloud computing services are always required to be with an essential and sufficient storage of all the required resources and which are to be utilized by the business client for a monthly or annual fee which has been charged by the service provider at the beginning. And this concept has been referred as similar and which is also common to as the Software-as-a-Service (or SaaS) model is a common concept which has also been found similar to the cloud computing system. In this concept the company is required to pay for the use of the service which can also be said as you pay as you go.

Disaster recovery: It has been recommended on a high priority to have a data back-up ready in case of any emergency (Baiju. 2014). Cloud computing tis the system which can be proven as a beneficial option for the business corporations as the system stores and saves the files or the data stored in it and further it can provide the same data in the emergency situation.

Flexibility – Flexibility is one of the biggest advantages of this mechanism. As mentioned above the business organization is required to pay the amount or the charge for the time duration or for the part of the service which they have used. The business corporations are provided with a limited flexibility for the use of the system and the service for which they have already paid an amount. For example if an individual or a business firm has small capital for investments and  starting up a business, so for this scenario the owners can make use of small cloud computing packages and services. Further an increase can be done in the use of the computing services as the business activities and the operations keeps on growing. And after a particular growth in the business income the owners can also opt for a bigger package of computing services. Setting-up of an automatic scale for the essential and required resource for the business corporation has also been done by some of the cloud service providers (stratospherenetworks. 2017). Also the business organizations can make necessary changes and modifications in the infrastructure. These modifications can be into making the network private network, public, or a combination of both.

Disaster Recovery

Accessibility – Access to the data at required moment is very much important. Cloud computing has provided this service to the business organization to access the data regardless of where the company stands or is operating in the world. The employees or the needed one can have access on the data or the operations which are based on cloud computing mechanism. The access will be granted to the desired by just clearing a complicated remote login procedures and which are required for the in- this purpose the most needed tool is a device that can provide access to the data or the information required through the web and an Internet connection which will be controlling the systems. This means the employees or the staff in the organization can have access anywhere and at any-time, from home, office or on the road at a client's office.

Sustainability – Business are prone to number of issues and risks at any-time. There are a number of issues which can be faced by the business such as a natural disaster which can strike the business at any time. But cloud computing is the mechanism which has emerged as the solution to this problem of risks due to natural disasters. By making use of this mechanism the company can feel risk free as the data which can be pertained to risk is stored somewhere else (Vishwanathan. 2017). But this advantage can also turn into negative if the disaster directly hits the cloud computing service.

Security of Your Data – The cloud computing system have been used by the business organizations for storing the confidential data and also safeguarding the same form various types of risks. But some-times the system fails to protect the data. And this has become as the prime or the main concern which is related to cloud computing systems. In simpler terms, the data or the confidential information that used to reside within the four walls of the business corporation now resides elsewhere and security and safety of the same is must. Addressing the security of the data must be done on priority basis and this is required to be done with care as the data stored in the cloud systems contains trade secrets of a number of business organizations, proprietary lists, files of the consumers and their records etc. There has been an estimate provided by the researchers that more that 60% of the service providers of cloud said that data security should be the responsibility of the end-user, Whereas on the other hand on the basis of another survey it has been inferred that about 35% of the end-users agreed that they should be held responsible for the duty of data security (Sotto, Treacy and McLellan, 2010). And on the basis of both the survey it can be clearly observed that there is a sense of inequality between cloud providers and cloud users about the concept of the security and the responsibility of the same. It should be in the mind of the business corporations who have been making use of the data that their confidential information stored in the computing systems is vulnerable to compromise and is exposed to risk at any-time. Author has described that as the companies and the service providers both have an idea about the risks and dangers they should also be prepared with the proper measures and precautions which are  necessarily required to be taken right from the start has been considered as an important step for the business organization. Whereas in case of the small business organizations who do not have adequate resources and right amount of investment for protecting their data from the risks. For this situation the cloud providers should offer a reasonably priced off-site solution which may be right for certain applications.

Flexibility

Costs When Under Attack – On the basis of the survey and the above research cloud computing is the tool which has to be considered as the low cost incurring mechanism. The system also provides some sought of additional benefits to the business entities. But in some scenarios it can be reason due to which the company will incur a number of additional expenses. For example, if a company's website comes under a distributed denial of service i.e. (D-DOS) attack. The reason behind this attack is that the typical goal of a D-DOS attack is to gobble up resources and which is done for rendering the server incapacitated. If the cloud computing provider has no precautions to fight against the risk of DDoS attacks, when the site is attacked, then service provider will have to simply begin to increase the resources that the site will be requiring during the attack and the cloud provider will charge for the extra resources used and which naturally will bring an increase in the expenses. It is of very much significance for the business corporation to ask the provider what kind of provisions they have to protect against this type of attack.

Fluctuations in the performance level – As the cloud system is globally operated and at a time the system and the applications running on servers for the business organizations are simultaneously used by other business corporations, the same applications are involved in providing the resources to other businesses too. Hence there will be fluctuations in the requirements and the demands made by the each and every user and which will develop impacts on the performance of the business organization and the share of the resources will be also on a varying note. Often, the service providers may claim that the resources available with the business entities are unlimited (azure.microsoft. 2017). This may be theoretically true, but from a practical point of view the hardware scalability is probably limited.

In the light of the above carried out research it can be concluded that the concept of cloud computing has to be considered as the most significant concept in terms of storing and safeguarding the confidential data of the business corporations for future references. Moreover it has been also considered as the new concept in the context of maturity and adoption. There has been a number of changes and predictions made under which the business corporations will undergo in the future, in terms of resources, issues, risks, and ultimately best practices and standards. Moreover the prime focus of the research has been provided to the benefits and the disadvantages which have been provided by the system. On-demand services can resonate positively with the current university tight budgets across the nation and other parts of the world. Further the benefits of the transition to cloud computing have been described in this above carried out reserach along with concerns regarding the general implementation of this application.
