Because cloud computing represents a major change in the way computing services will be accessed and delivered in the future, Intel is committed to developing computing capabilities to support the cloud, and is providing leadership to bring cloud computing solutions to market.

Cloud-based IoT platforms are gaining momentum in recent years with notable advances made by large corporations such as Microsoft, Amazon, and Google. However, although some practitioners and academics emphasize the opportunities that SaaS offers companies, others already predict its decline due to the considerable risk involved in its deployment. Abschließend wurde der Kriterienkatalog in mehreren Workshops mit einem deutschen Cloud-Service-Zertifizierungsanbieter (TÜV Rheinland) diskutiert und geschärft. In general, we can, summarize all these services with the unified ”Anything as a. Service” – XaaS, or EaaS (Everything as a Service).

Cloud Computing Deployment Models. Like a private cloud, community, ownership can also be managed by a community or third party, cloud is defined as a deployment model where services are, shared among a community (community) community with, common requirements where the service is managed by at, least one member of that group. For SaaS, maintenance is performed by the, user should know exactly which version he uses.

Types of Cloud Deployment Models. the Many organizations turn to the cloud for greater flexibility and dynamic scalability, but IT and financial teams must work together to address the complicated pricing scenarios. The public cloud is also suitable for, the organization, that needs a higher performance in the short, term, for example to solve a project. We first developed a research model grounded in an opportunity-risk framework, which is theoretically embedded in the theory of reasoned action. Quality of Service Management in Clouds,” rev.

According to NIST SP 500-291 [8] we know three, basic models - software as a service (SaaS), platform as, service (PaaS) and infrastructure as a service (IaaS). Since the hybrid CC system is a, combination of previous deployment models, it is not possible, The user can only use one particular application, or it can, be a set of applications that make up a specific platform, or, on his own environment. Platform as a Service (PaaS) offers the user, a platform in CC environments where the user can run their, own suite of applications or use it as a support platform for, existing solutions. Storage services such as Google Drive, Another benefit to the user is that the entire application is, run by the provider. Interoperability is also the ability of one service to work, with other CC services. If needed, it can add or remove active, elements to respond flexibly to their own requirements or, you-go” model, which means that the user pays only for, the service he actually uses.

Calculus" in: Journal of information, control and management systems, Collaboration is key to earning cloud computing cost savings. We grouped closely related standards together for the sake of brevity. The Cloud Industry Forum has established a Cloud Standards working group comprising interested members. Service level agreement. It can also be, a combination of different CC environments. Towards the end-goal of a thorough comprehension of the field of cloud computing, and a more rapid adoption from the scientific community, we propose in this paper an ontology of this area which demonstrates a dissection of the cloud into five main layers, and illustrates their interrelations as well as their inter-dependency on preceding technologies. authorization, confidentiality, monitoring, or management, the provider and the user of the CC service. It can be managed either by the, customer itself or by a third party that the customer orders by, management. In due course of time cloud is going to become more valuable for us and we must protect the data we put on cloud while maintaining the high quality of service being offered to us. On the other hand, cost advantages are the strongest driver affecting IT executives' perceptions of SaaS opportunities. OData 6. The user is responsible, for the running of applications and the overall security of their, Reference architectures of CC can be divided into two. Working P.O. Examples include compilers and interpreters, of different programming languages. Figure 1 shows the CC reference architecture according to, NIST [7], which defines the main roles, their activities and, functions in the CC. Cloud computing offers the potential to dramatically reduce the cost of software services through the commoditization of information technology assets and on-demand usage patterns. potreby KIS, ilina, 2015. The Open Group Cloud Ecosystem Reference Model. The purpose of this working group is to identify and monitor progress in the development of cloud standards as they relate to the interests of the CIF Code of Practice and members of the Forum. The second group consists of layer-based architectures. Thanks to its flexibility, the XMPP is used in a large domain, from a simple application such as instant messaging to a larger one such as remote computing and cloud computing [94]. In the ne, will present the competences of two basic roles – the provider, and the user in the three basic deployment models according, The SaaS user only has an application interface that he has, ordered from the provider. ...

Conference: 2018 16th International Conference on Emerging eLearning Technologies and Applications (ICETA). A key part of that effort is Intel’s work in driving standards.

It does not need to. Our findings suggest that in respect to both SaaS adopters and non-adopters, security threats are the dominant factor influencing IT executives' overall risk perceptions. Many cloud computing organizations and informal groups are focused on addressing standards issues in regards to the cloud environment. This includes, for example, a number of computational, resources, the response time and the overall delay for the, requirements, or the data throughput through the active, the CC because users are interested in the possibility of, migrating their data and applications between different, providers at the lowest cost and downtime.

Furthermore, we find significant differences between adopters' and non-adopters' perceptions of specific SaaS risks and opportunities, such as performance and economic risks as well as quality improvements, and access to specialized resources.

A hybrid, cloud can be managed by an organization or a third party, Hybrid CC systems represent a situation, where interaction, between different CC service deployments is needed, but these, services have different types of deployment. groups. Private CC systems according to [9] provide the follo, can limit access not only to services but also to physical, resources of the service. IT providers have heralded software-as-a-service (SaaS) as an excellent complement to on-premises software addressing the shortcomings of previous on-demand software solutions such as application service provision (ASP). Ours is the first study to analyze the opportunities and risks associated with adopting SaaS as perceived by IT executives at adopter and non-adopter firms. As. of cloud services and types of roles in CC. The NIST recommendation, defines IaaS as an option for a user to create and operate, their own infrastructure on which their own applications can, run.

Cloud Common Standards in The ITU-T has created the Reference architecture of CC, This architecture is composed of layers and cross-cutting, aspects that can not be assigned to one layer, but hav, impact on multiple layers. At present, however, service models are being created by providers to users. According to, NIST SP 500-291, a hybrid cloud is called an infrastructure, that consists of multiple CC infrastructures (private, com-, munity, and public CC). Users of the public CC can be, anyone with access to the Internet. SOC 15. These CC, paradigm that allows the network to access a set of shared, physical or virtual resources.
