The Economic Case For Cloud Computing

Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.

Cloud computing has set a trend in the information technology arena that has sparked the interest of all who utilize the internet on purpose and unsuspectingly. Initially, the primary purpose of cloud computing was to provide a centralized data bank that organizations could use for quick data access. Its use has been quickly adapted, however, beyond business use to become the first option for personal use. The advantages and disadvantages of implementing such a shift from business to personal are varied, yet, statistically, according to the CISCO Global Cloud Index: Forecast and Methodology, 2014-2019 White Paper, its public use is on the rise. The report notes that “by 2019, 56 percent of the cloud workloads will be in public cloud data centers, up from 30 percent in 2014 and by 2019, 44 percent of the cloud workloads will be in private cloud data centers, down from 70 percent in 2014”. Though disadvantages with regard to data security is prominent, users have deemed that its implementation will still promote greater benefits than loss.

We would like to provide the benefits of cloud computing without any troubles to propel in the direction it is designed for. This is to be achieved by preventing the owner's data from all risks associated and providing a cloud model that is more secure and efficient. The proposed model shall overcome the security risks defined by the security functions over cloud computing, as follows in (Passent M. et al., 2015):

The majority of us have been found out about the most cloud security disappointments in which all the cloud innovation organizations are kept on developing, despite everything they endure a similar kind of issues in-house infrastructure's. Distributed computing has turned into a greatest market in the present innovation. In a report of 2016, experts at Gartner anticipated that exchanging to cloud will influence $1 Trillion in Information innovation in the following five years. Cloud administrations showcase has developed to a degree level that it was not a striking level of aggregate it is spending, which was creating new innovations and new businesses which are conceived in the cloud. At the point when cloud administrations are going

The economic case for cloud computing is compelling and at the same time there are striking challenges in its security. The concepts of cloud computing security issues are fundamentally new and intractable. What appears new is only relative to traditional computing that has been practiced since several years. Many such security problems have been giving attention since the time-sharing era. Cloud computing providers have and can build datacenters as large due to their expertise in organizing and provisioning computational resources at as low cost as possible.

Cloud computing has been around for over two decades, yet keeps evolving and growing in the scope of services available to businesses. With the allure of pay on demand and instantly scalable resources, cloud computing offers more services online than ever before and that kind of demand drives the need for data security.

DATA SECURITY IN CLOUD COMPUTING Introduction: Cloud computing has prompted a movement in how individuals consider IT frameworks structural engineering. Numerous associations today are either executing cloud-based services, or assessing which cloud-based measures they will be portraying later on. As indicated by Gartner Inc. distributed computing is "no less compelling than e-business". This sprocess in building design from an undertaking normal server-based framework to a cloud-based framework will have related expenses of passage and dangers, yet it can bring about inconceivable advantages in reserve funds and in IT and business deftness.

The use of cloud computing creates a growing interdependence among both public and private sector entities and the individuals served by these entities. This paper provides a snapshot of the advantages of cloud computing and the risk areas specific to cloud services which clients of cloud services should be aware of. The future of cloud computing is certainly exciting, but moving more of our lives online means we will inevitably have to consider the consequences. Cloud computing means dependence on others and that could limit our privacy because

This section of paper includes why we need cloud computing as a security control tool against the cyber criminal activities and in how many ways it can be implemented. As we are living in a technical era, many aspects of our lives rely on the Internet and computers, including transportation, communications, government, medicine, finance and education. Consider how much of our personal information is stored either on our own computer or on someone else’s system.

Cloud computing is a shared resource that holds valuable data from masses of people and organisations and is therefore an easy target for hackers. Security within cloud computing involves a set of control-based technologies, polices, processes and standards to protect information, data applications and infrastructures related to cloud computing usage. Security within this area addresses the physical and logical security issues across the different service models as well as how these services are delivered ie.via the public, private or hybrid model. There are many points of entry for an attacker in the cloud environment and people are more exposed to data breaches than they think e.g. using an insecure website on your mobile phone or if a database administrator shares a password, personal details can be accessed.

The primary purpose of cloud computing is resource sharing. The biggest risk when multiple organizations share resources is of data misuse. So to prevent this risks it is essential to secure the data stored in the repositories, data in the transit and processes. To enhance the security in cloud computing,it is vital to provide authorization, authentication and access control for data that is stored in cloud.

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Nowadays, cloud computing has penetrated into every corner of Internet industry with its low-cost computing resources, easy scaling architectures, and everywhere on-demand services. Security issues is the most important issue faced by people in the use of cloud computing data storage services [1].The advantage of cloud is cost savings. The prime disadvantage is security. The security risks associated with each cloud delivery model vary and are dependent on a wide range of issues counting the understanding of data quality’s, cloud architectures and safety measures organizes engaged in a exacting cloud atmosphere. With public audit capability, a trusted entity with expertise and capabilities data owners do not hold can be entrusted as an outside

Security Issues : There are many challenges in the area of cloud computing and security is one of them. Increasing the level of security is required for improving the quality of cloud based services. Location of data is a important factor in the security of cloud based computing. Transparency of the data location provides the flexibility for cloud based computing, but this is also a threat related to security. For cloud users, to maintain their personal data is a major issue related to cloud computing security. Technical security and policies for cloud users plays a vital role in the cloud security. To build trust and establish it for customers who want to use cloud services, is another issue related to the cloud based computing. Security attacks is another issue related
