Opis:: Chmura obliczeniowa (Cloud Computing) stanowi obecnie ważny trend na rynku IT. Usługi Cloud Computing polegają na dostarczeniu i udostępnianiu wydajnych i skalowalnych zasobów IT (sprzętu, oprogramowania i usług), a usługodawca, którym jest zwykle podmiot zewnętrzny (ewentualnie wewnętrzny dział IT), oferuje usługi informatyczne odbiorcom za pośrednictwem sieci. Chmura obliczeniowa dynamicznie się rozwija zarówno w Polsce, jak i poza jej granicami i coraz częściej uzupełnia, a nawet zastępuje klasyczną formę wdrożeń technologii informatycznych w organizacjach. W artykule, na bazie raportów i opracowań firm analityczno-doradczych i innych organizacji, przedstawiono aktualny stan i prognozy rozwoju Cloud Computing w Polsce oraz niektórych krajach UE. Wskazano również bariery warunkujące dalszy rozwój Cloud Computingu w Polsce.
Cloud computing is now an important trend in the IT market. Cloud Computing services function by delivery and provision of efficient and scalable IT resources (hardware, software and services), and the service provider, which is usually an external subject (or internal IT department), offers IT services to customers via the network. Cloud computing is growing rapidly, both in Poland and abroad, and more often complements or even replaces the classical form of implementation of information technology in organizations. In the paper on the basis of reports and studies research prepared by different organizations the current status and forecast of Cloud Computing development in Poland and in some EU countries were presented. It also identified barriers conditioning the further development of Cloud Computing in Poland.

Opis:: A hybrid is a mixture of two different things, resulting in something that has a little bit of both. Like the rare zeedonk, a hybrid of a donkey and a zebra. Hybrid refers to many areas of life biology, electrical power generation, electronics, film, games and sport, music, literature, vehicles. Other examples of the use of hybrids Hybrid security, a type of economic instrument, Hybrid word, a word derived from more than one language, Hybrid market, a system allowing stock trades to be completed either electronically or manually, Hybrid organization, an organization that mixes elements of various sectors of society The world around us is a hybrid and it is no longer just a state of transition. This also applies to Cloud Computing. Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Business requires a flexible IT infrastructure that can scale on demand. A hybrid cloud gives organizations the best of both worlds, so company can take advantage of external resources when it makes sense from business perspective. Varied use cases for hybrid cloud composition exist. For example, an organization may store sensitive client data in house on a private cloud application, but interconnect that application to a business intelligence application provided on a public cloud as a software service. This example of hybrid cloud extends the capabilities of the enterprise to deliver a specific business service through the addition of externally available public cloud services. Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses. Another example of hybrid cloud is one where IT organizations use public cloud computing resources to meet temporary capacity needs that cannot be met by the private cloud. This capability enables hybrid clouds to employ cloud bursting for scaling across clouds. Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and „bursts” to a public cloud when the demand for computing capacity increases.

Opis:: In recent years ad-hoc parallel data processing has emerged to be one of the killer applications for Infrastructure-as-a-Service (IaaS) clouds. Major Cloud computing companies have started to integrate frameworks for parallel data processing in their product portfolio, making it easy for customers to access these services and to deploy their programs. However, the processing frameworks which are currently used have been designed for static, homogeneous cluster setups and disregard the particular nature of a cloud. Consequently, the allocated compute resources may be inadequate for big parts of the submitted job and unnecessarily increase processing time and cost. We discuss the opportunities and challenges for efficient parallel data processing in clouds and present our research project Nephele. Nephele is the first data processing framework to explicitly exploit the dynamic resource allocation offered by today’s IaaS clouds for both, task scheduling and execution. Particular tasks of a processing job can be assigned to different types of virtual machines which are automatically instantiated and terminated during the job execution. Based on this new framework, we perform extended evaluations of Map Reduce-inspired processing jobs on an IaaS cloud system and compare the results to the popular data processing framework Hadoop.

Opis:: Today cloud computing becomes one of the most attractive topics due to the wide opportunities that is provided which aims to enhance the electronic services to a higher-level providing cost saving, expanding possibilities, storage in demand and the huge intake capability as well. Security is one of the most important process that should be implemented in every cloud structure level, especially with data in case of processing or storing to keep it save from unauthorized access to overcome the security challenges and difficulties, which face both provider and users in cloud. In this paper a study to compare the security algorithms for encryption/decryption files has been done to evaluate the performance impact with memory capacity, processing time and algorithms running time. The comparison has been done between three encryption algorithms AES, DES, and Blowfish to determine the performance of each one in cloud storage. From the experimental results we found that DES is faster in running time compared to other algorithms as well as AES considered to be the safest one in data protection.

Opis:: Cognition is a domain of thinking creatures, isn't it? Based on that computers cannot learn anything more than was in the initial data feed. In this article, I just want to defend that nowadays technical solutions can break this rule. The aim of this article is to provide a short technical overview what Machine Learning (ML), Artificial Intelligence (AI) and Neural Networks (NN) were before in the area of standalone gigantic servers, and how do they look now in Cloud Computing (CC) times. The ML paradigm is not any more reserved for big enterprises only but now is available for single internet user. I just want to present AWS and Azure, as the biggest CC providers, functionalities and potential usage of such Cognitive Services (CS) in current internet services. The great example is for instance bot usage instead of diving deep in the FAQ on the company website or digging into the corporate wiki. Another big area is graphics analysis and sound or text recognition. Those are only examples of predefined CC functions ready for use right now in the public cloud.
