What Is The Most Important Challenges In 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.

User can store their data on cloud and reveal from the local data storage and its maintenance. Cloud is in a distributive in nature includes shared pool of configuring resources both in hardware and software. As an increasing number of clients who store their

The first scenario that will be examined is looking at Cloud Computing from the perspective of security. Many small and medium sized businesses utilize the internet and Cloud Computing to conduct business and transfer money from system to system as well as report on financial accounting data. With that being the case, it is crucial that whatever system the business is working with pays very close attention to security needs to ensure that this data is protected from unauthorized sources viewing or manipulating it.

Security is typically ranked the top cloud computing adoption concern. Many feel that cloud is not yet a secure enough option for storing and processing mission critical or customer-sensitive data, and may never be. So it’s important to evaluate security solutions provided by various vendors to see what data protection you will be receiving from a specific cloud vendor for your mission critical and sensitive data. Comparison of security solutions provided by four well known cloud service providers is listed as below.

Cloud services: The organizations have been highly dependent on the cloud services. The cybercriminals have been seeking ways to exploit corporate security policies for protecting cloud services. The cloud services have been providing immense risk of data being disclosed deliberately or accidentally. The hosting companies have a greater ease of control over the private data and information and can even communicate between the end user and access his user data even without his permission. Therefore this threat has to be placed at the highest priority. Additionally, the cloud providers have the authority to the share information with any of the third parties even without any warrant. All these activities poses privacy concerns as the data can be access on the cloud anywhere and anytime where the information can be deleted, or even altered. All these activities have further left a room for potential unwanted disclosure of data and information on the cloud. Thus using cloud services in an organization poses a threat to exploitation and stealing of confidential data by their competitors, cybercriminals and vigilante justice seekers (Shaikh, F. B., & Haider, S., 2011).

While it is true that cloud computing models can vary it all comes down to three components consisting of the Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These work to manage your cloud computing service level by way of the surrounding management layer.

The final segment in cloud computing, known as the infrastructure, is very much the backbone of the entire concept. Infrastructure vendors provide the physical storage space and processing capabilities that allow for the all the services described above. The products in this segment are slightly more varied than those in the other areas of cloud computing but include ones such as managed hosting, and development environments (such as Google gears) that allow users to build applications. Cloud storage, such as Amazon 's S3, is also considered to be part of the infrastructure segment.

The ever-changing demands and innovations keep on bringing new changes in information technology. Currently, cloud computing is considered as the most critical application to Web 2.0 which has revolutionized content sharing platforms. Web 2.0 is characterized by higher user interactivity, enhanced communication channels, and more pervasive network connectivity (Fuchs et al., 2013). On the other hand, cloud computing refers to technology model for enabling ubiquitous access to computing services such as a database, storage, and servers over the internet, also known as the cloud (Mathkunti, 2014).

As depicted in figure 3, the technical details, arrangements and management of the cloud service providers’ network is transparent to the cloud user. From the end of the cloud user, the service from the provider comes in the form of SaaS, PaaS or IaaS where the cloud user has no intention or worry about what goes on in the internal arrangement of the cloud service providers’ network. Any disruption of any form for whatever is the reason, deem to the cloud users either as service unavailability or quality deterioration – its affect and ways to counter this disruption is a critical part for the cloud infrastructure. Security issues might play a stimulating role as a driving factor for any aforementioned disruption.

Reaching the point where computing functions as a utility has great potential, promising innovations we cannot yet imagine. Customers are both excited and nervous at the prospects of Cloud Computing. They are excited by the opportunities to reduce capital costs. They are excited for a chance to divest themselves of infrastructure management, and focus on core competencies. Most of all, they are excited by the agility offered by the on-demand provisioning of computing and the ability to align information technology with business strategies and needs more readily. However, customers are also very concerned about the risks of Cloud Computing if not properly secured, and the loss of direct control over systems for which they are nonetheless accountable. To aid both cloud customers and cloud providers, CSA developed “Security Guidance for Critical Areas in Cloud Computing”, initially released in April 2009, and revised in December 2009. This guidance has quickly become the industry standard catalogue of best

Cloud computing has provide the software and services the demand of the client. It offer the client to connect to computer resources and access the resources with a previously unknown level of ease because of this new cloud become the new ground of development of a generation of delivering service and store the privacy and security may be include security concern among user of the cloud have become concern of 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)

Cloud computing security or also known as cloud security talks about a broad set of technologies, policies and controls deployed to protect applications, data, and the corresponding infrastructure of cloud computing. The cloud is a great invention to allow high capacity storage of data but without the cost to allow sharing of resources in a quick and timely manner. With technology becoming advanced in such a short amount time, new steps must be created to protect people information from being hacked. Hacker’s mission is determined by greed, anger, or request to damage their victims and the organization they might be a part. No one can actually stop all the potential vulnerabilities from being breached, but the provider and clients

There are three main categories of cloud computing services. They are SaaS known as software as a service, IaaS known as infrastructure as a service, PaaS known as platform as a service and FaaS known as function as a service.

The architecture of Cloud Computing is consist of many cloud components but we can divide the cloud architecture into two parts:
