What is the current state of cloud service research and its promise for the future? A systematic literature review

The information technology (IT) industry has recently witnessed the proliferation of cloud services, which have allowed IT service providers to deliver on-demand resources to customers over the Internet. This frees both service providers and consumers from traditional IT-related burdens such as capital and operating expenses and allows them to respond rapidly to new opportunities in the market. Due to the popularity and growth of cloud services, numerous researchers have conducted studies on various aspects of cloud services, both positive and negative. However, none of those studies have connected all relevant information to provide a holistic picture of the current state of cloud service research. This study aims to investigate that current situation and propose the most promising future directions. In order to determine achieve these goals, a systematic literature review was conducted on studies with a primary focus on cloud services. Based on carefully crafted inclusion criteria, 52 articles from highly credible online sources were selected for the review. To define the main focus of the review and facilitate the analysis of literature, a conceptual framework with five main factors was proposed. The selected articles were organized under the factors of the proposed framework and then synthesized using a narrative technique. The results of this systematic review indicate that the impacts of cloud services on enterprises were the factor best covered by contemporary research. Researchers were able to present valuable findings about how cloud services impact various aspects of enterprises such as governance, performance, and security. By contrast, the role of service provider sub-contractors in the cloud service market remains largely uninvestigated, as do cloud-based enterprise software and cloud-based office systems for consumers. Moreover, the results also show that researchers should pay more attention to the integration of cloud services into legacy IT systems to facilitate the adoption of cloud services by enterprise users. After the literature synthesis, the present study proposed several promising directions for cloud service research by outlining research questions for the underexplored areas of cloud services, in order to facilitate the development of cloud service markets in the future.

Pilvipalveluilla joustavuutta ja kustannustehokkuutta Stora Enso Metsän tietojärjestelmiin

Tämän diplomityön tavoitteena oli selvittää hyödyttääkö Stora Enso Metsää tietojärjestelmien siirto perinteisistä konesalipalveluista pilvipalveluihin. Stora Enso Metsällä on paljon erilaisia suunnitteluun liittyviä eräajoja. Joitakin niistä ajetaan vain muutamia kertoja vuodessa kuten tehtaiden puuntarve, toisia muutaman kerran kuussa kuten kuljetusten malliajot tai muutaman kerran viikossa ajettava korjuun suunnittelu. Niissä tapauksissa palvelimet voidaan käynnistää erikseen ja käyttää niitä vain silloin, kun niitä oikeasti tarvitaan. Työn lopputuloksena havaittiin, että pilvipalveluiden käyttöönotto tuo kustannussäästöjä ja palveluiden hallintaan joustavuutta. Itsepalveluna toteutettuna palvelimia voidaan hallinnoida joustavasti kustannusten säästämiseksi. Pilvipalveluilla voidaan nopeuttaa projektien läpimenoa ja kohdentaa käyttökatkot tarkemmin koska siihen ei välttämättä tarvita toimittajan työtä lainkaan. Loppujen lopuksi asiakkaan on erittäin vaikea tietää kuinka paljon kustannuksia on jaettu eri tavalla eri palvelujen välillä.

How Cloud Services may Enable SMEs to Overcome International Growth Challenges: Finnish SMEs in the IT Industry

Digitalization and technology megatrends such as Cloud services have provided SMEs with a suitable atmosphere and conditions to internationalize and seek for further business growth. There is a limited amount of research on Cloud services from the business perspective and the limitations and challenges SMEs encounter when pursuing international business growth. Thus, the main research question of this study was how Cloud services may enable Finnish SMEs to overcome international growth challenges. The research question was further divided into three sub-questions dealing with matters related to features and characteristics of Cloud services, limitations and challenges Finnish SMEs experience when pursuing international growth of business, and benefits and advantages of utilizing Cloud services to mitigate and suppress international growth challenges. First, the theoretical framework of this study was constructed based on the existing literature on Cloud services, SMEs, and international growth challenges. After this, qualitative research approach and methodology were applied for this study. The data was collected through six semi-structured expert interviews in person with representatives of IBM, Exidio, Big Data Solutions, and Comptel. After analyzing the collected data by applying thematic analysis method, the results were compared with the existing theory and the original framework was modified and complemented accordingly. Resource scarcity, customer base expansion and retention, and lack of courage to try new things and take risks turned out to be major international growth challenges of Finnish SMEs. Due to a number of benefits and advantages of utilizing Cloud services including service automation, consumption-based pricing model, lack of capital expenditures (capex) and huge upfront investments, lightened organization structure, cost savings, speed, accessibility, scalability, agility, geographical expansion potential, global reaching and covering, credibility, partners, enhanced CRM, freedom, and flexibility, it can be concluded that Cloud services can help directly and indirectly Finnish SMEs to mitigate and overcome international growth challenges and enable further business growth.
