An important trend in today’s economy is to reduce the carbon footprint of organizations, businesses and households. Modern technologies, including ICT solutions, contribute to the reduction of CO2 production. The article focuses on the potential of using the cloud computing model in managing a modern and intelligent city. Modern city offices have an extensive IT infrastructure. With the emergence of new services provided online by the offices, the server infrastructure is also developing. Server rooms together with additional devices are characterized by high demand for electricity. Along with this, significant amounts of CO2 are produced. An alternative is the use of Cloud Computing solutions, which contribute to a significant reduction of the carbon footprint. The paper analyses potential solutions that can be used in city offices. The benefits and positive impact on the environment were highlighted. The empirical research was conducted based on questionnaires received from city offices. The results obtained indicate that city halls contribute significantly to the production of CO2. Moving IT services and solutions in whole or in part to cloud computing should be considered as one of the important elements of managing a smart and green city.
The article presents the concept of unified communication in cloud computing. Nowadays communication is becoming a key management factor because of the increasing role of information resources. New concepts and models of communication are the result of the constant evolution of information technology. Multidimensional and integrated communication is an important element of modern business processes, determining their efficiency, effectiveness and performance. The first part of the study presents the basic communication tools in the organization. On this basis, the essence of Unified Communications as a Service (UCaaS) is presented as a new communication model. Next, the benefits and risks resulting from the use of UCaaS were pointed out. The last part of the article describes examples of the practical implementations of UCaaS in Polish enterprises.
Nowadays, the Software as a Service model is an increasingly popular method of acquiring and using IT systems such as project management support systems. The SaaS model consists in making IT systems available in the Internet space for a fee, which users can use online. The aim of the article is to analyse the possibilities of using project management support systems offered in the SaaS model in the activities of a virtual organization. The article introduces virtual organizations, emphasizing their features, structure and the role of IT technology in their functioning. The next section presents the general characteristics of the SaaS model and highlights the benefits and risks of using PMS systems in the SaaS model. Then, various conditions related to the purchase and use of PMS systems were signalled in the form of a service supporting the activities of a virtual organization. Finally, some PMS systems available in the SaaS model that can support the activities of domestic and international virtual organizations were listed.
Dynamic changes in the environment with constant technological developments, influence the emergence of new forms of conducting business. One of the important forms of conducting a contemporary market activity, becomes a model of virtual organization. Generally, virtual organization is a collective of independent, specialized and often geographically dispersed business units (eg. enterprises, divisional parts of companies, institutions, individuals), combining their resources and forming the cooperation for the realization of a particular purpose.The main factor enabling the cooperation of subjects, grouped within the frame of virtual organization, are a variety of resources and ICT tools (Information and Communication Technology). High efficiency and effectiveness of ICT, requires the adoption of specific information strategies of virtual organization. Currently, the Cloud Computing is an increasingly popular service model, which provides and lets for ICT use. The aim of the article is to present information strategy of VO, based on the Cloud Computing model. To achieve that ambitious objective, at the beginning of the article, the VO outline and ICT’s role in its activity, is presented. Then, referring to the M.J. Earl’s frame, a information strategy of VO was discusses, together with the indication of the role and place of Cloud Computing in VO’s information strategy. Article tops the list of national and international Cloud Computing solutions, that can support information strategy for virtual organizations.
