Integrating Conventional ERP System with Cloud Services : From the Perspective of Cloud Service TypeShi, Jia January 2012 (has links)
It is proved that cloud computing has many benefits, and cloud services with flexible licensing model and cost saving features bring opportunities to enterprise's IT operations. Conventional ERP system, an important component of enterprises, is impacted by on-demand cloud services also. Integrating conventional ERP system with cloud services becomes a trend because it brings new processing capabilities without introducing significant changes to existing system. But previous studies about integrating ERP and cloud usually focused on SaaS (Software as a Service). PaaS (Platform as a Service) and IaaS (Infrastructure as a Service) are not discussed much. People sometimes even confuse cloud service with SaaS. Therefore, the objective of this paper is to present a framework that can describe respective implications of integrating ERP with three types of cloud services: SaaS, PaaS and IaaS. Qualitative methods such as systematic literature review and interviews are adopted to execute the research, so data collected through different sources can complement each other in order to support presenting the framework of integrating conventional ERP system and cloud services. The integration at SaaS level is for achieving immediate business value and productivity enhancement. At PaaS level the objective of integration is to enhance software development life cycle management. And the main integrating intent at IaaS level is to enable scalability and reliability of hardware resources without changing existing IT infrastructure. Furthermore, challenges and opportunities for integrating ERP with different cloud services are studied and motivation is derived from analyzing. Finally the key points are arranged in the presented framework of integration between conventional ERP systems and cloud services.

Cloud Services : ett förslag på hur de kan användas inom e-handel / Cloud Services : a proposal on how they can be used in e-commerceSkoglund, Erik, Auyeung, Ginwah January 2011 (has links)
E-handelsföretagen försöker ständigt sträva efter expansion. Samtidigt så vill de ha en IT-lösning som är så kostnadseffektiv som möjligt. Säkerhet är också någonting som företagen värderar väldigt högt. Cloud services är något som kan användas för detta. Men e-handelsföretagen måste först och främst känna att de har någonting att utvinna av dessa. Säkerheten är här ett hinder. Efter våra intervjuer med e-handelsföretagen inom klädesbranschen i Borås så betonade samtliga företag hur viktigt det var att hemlig företagsinformation absolut inte fick läcka ut. Det är säkerhet som är den största frågan med moln. Ansvaret för säkerheten ligger just på företaget som köper tjänstens sida. Även om en cloud provider erbjuder säkerhet, backup och bra upptid, så är det fortfarande upp till företaget att se till att de levererar detta. Samtidigt så går det mycket diskussion kring ämnet och många menar att det är nytt och bristen på kunskap som gör att företagen är rädda för riskerna. Vill företaget absolut inte att utomstående ska få komma åt viktig företagsinformation, då kan de välja att ha en kombination av privata och publika moln i det som kallas hybridmoln. Detta beror på att privata moln är byggda och driftade inom företaget. På så vis är data som finns lagrat i det privata molnet inte delat med andra företag. Det viktiga är för företaget att själva se vad de själva har för krav på säkerhet. Finns det krav på säkerhet på vissa delar men inte på andra, så kan hybridmoln vara en lösning. Genom att intervjua tre av de största e-handelsföretagen i Borås så har vi sett en tendens till detta.Det finns många områden som de företag vi intervjuat skulle kunna använda sig av cloud services på. Vi har fokuserat på kärnverksamheten, de stödsystem som de använde, webbsidan, kommunikation och kontorsprogram. Anledningen till detta är att företagen som vi intervjuat tyckte att dessa delar var viktigast. / Program: Kandidatutbildning i informatik

Propuesta de un marco de trabajo en Cloud Computing para el soporte de la evolución tecnológica en una Institución PúblicaPolo Urbina, Karina Tatiana, Ruiz Wilson, Yuri Antonovich 09 January 2020 (has links)
La Institución Pública es un organismo encargado de la recaudación en el Perú vinculado al Ministerio de Economía y Finanzas, y tiene como Misión transformarse en la administración tributaria y aduanera más exitosa, moderna y respetada de la región. Para eso desde hace algunos años la institución ha comenzado a lanzar iniciativas de proyectos de software que utilicen cloud computing, para que de esta forma puedan trabajar de manera más eficiente la gestión y compra de infraestructura, así como poder atender la demanda creciente de servicios digitales solicitados por los contribuyentes.
La presente tesis analizó la forma de cómo la Institución Pública fue adoptando cloud computing en sus proyectos de software, y como esta adopción puede ser mejorada al contar con un marco de trabajo que le permita tener pautas de cómo lanzar iniciativas que involucren en su desarrollo el uso de cloud como base tecnológica, y como esto debe estar alineada a la estrategia de crecimiento de servicios digitales que la Institución Pública desea ir cubriendo poco a poco para mejora su servicio hacia los contribuyentes. / The Public Organization is an institution in charge of tax collection in Peru, and linked to the Ministry of Economy and Finance, and has as its main mission to become the most successful, modern and respected tax and customs administration in the region. For this reason, for some years ago, the institution has begun to launch software project initiatives that use cloud computing, so that they can work more efficiently in the management and purchase of infrastructure, as well as being able to meet the growing demand for digital services. requested by taxpayers
The current thesis analyzed how the Public Organization was adopting cloud computing in its software projects, and how this adoption can be improved, by having a framework that allows it to have guidelines on how to launch initiatives that involve in its development the use of Cloud as a technology base, and how this should be aligned with the digital services growth strategy that the Public Organization wishes to gradually cover to improve its service to taxpayers. / Trabajo de investigación

Digital security monitoring of cloud services - SLA Analyser- Availability Monitoring tool for DB Cloud ServicesGupta, Sneha, Anika, Mosammath Nazifa Anjum Islam January 2023 (has links)
Cloud computing is in current demand and widely used for businesses because of its scalability and flexibility. An agreement is signed between cloud providers and customers to guarantee the level of services are available as promised, it is called Service Level Agreement (SLA). To assess if the services are compliant with SLA, availability of the cloud services is important to be monitored. There are some existing monitoring tools provided by the cloud service providers. However, those can be often biased that leads to calls for independent SLA evaluation. This study aims to solve the problem of verifying service availability parameters in terms of uptime/downtime against SLA by proposing a monitoring tool. This paper focuses on reliable assessment of SLA for both customers and service providers. Furthermore, this research discusses the challenges of SLA tracking and consequences of not assessing it. This study also explores that automated monitoring systems minimizes human-effort, time and the potential risk of errors. This approach is even more essential for organizations that use multiple cloud services from different vendors. The proposed monitoring tool can automatically verify the SLA by monitoring the availability of the cloud services. To avoid business losses and maintain reputation for customer trust, it is crucial to validate the SLA. The research problem related to SLA monitoring is challenging in terms of relevant previous studies of this area. Using experiment-based research strategy and quantitative data analysis method, the results have shown that the proposed solution is able to monitor the service availability and validate with SLA. The recommended solution is of significant interest to organizations as they are migrating and using single or multiple cloud services by different vendors as per the business need. The monitoring system serves as a valuable tool for both customers and service providers to solve issues related to availability monitoring of the cloud services and ensure the SLA commitment is met.

Increasing the robustness of a service in a complex information flowJohansson, Albin January 2019 (has links)
In complex information flows where a lot of varied data is transmitted through many companies and divisions, incidents will occur. When Visma Spcs had an incident where invoices sent from Visma to Visma's customers were duplicated and the service meant to receive the transactions did not handle the duplicates properly. They decided that the receiver service was to be upgraded to prevent this incident from happening again, as well as fixing some other issues the service had had. Incidents like this one must be investigated and a solution must be implemented to decrease the likelihood that similar incidents will happen again. In this report, the reader will see examples on how this can be handled and the benefits of tackling technical debt, along with how much more complicated the solutions might get if the service is not allowed to be taken offline.

Previous issue date: 2018-11-06 / The present work will expose a highly relevant topic at current time, the cloud service, an extremely intriguing theme in legal tax discussions, object of several debates by the exponential change of paradigms. It started with the knowledge of these tools to later learn about their legal nature, protection and form of economic exploitation. Entering juridical field, the constitutional principles of taxation dealing with federation, legal certainty and tax legality (tax typicity) were explored, since they are relevant to the debate about tax jurisdiction, legal limits and archetypes of taxes, such as the definition of concepts or types by the original constituent. Thus, the concept of service and merchandise was approached in Federal Constitution of 1988, as well as the position of the doctrine and the Federal Supreme Court, examining the cases of greater repercussion. Finally, it analyzed the conflict of jurisdiction between States and Municipalities for the taxation of Software as a Service (SaaS) / O presente trabalho exporá tema de grande relevância na atualidade, o serviço na nuvem, questão extremamente intrigante nas discussões jurídico-tributárias, objeto de diversos debates pela exponencial mudança de paradigmas. Partiu-se do conhecimento dessas ferramentas para, posteriormente, conhecer sua natureza jurídica, proteção e forma de exploração econômica. Adentrando a matéria jurídica, foram explorados os princípios constitucionais tributários que tratam da federação, da segurança jurídica e da legalidade (tipicidade) tributária, posto serem relevantes para o debate acerca da competência tributária, dos limites jurídicos e dos arquétipos dos tributos, como a definição de conceitos ou tipos pelo constituinte originário. A partir de então, abordou-se o conceito de serviço e de mercadoria na Constituição Federal de 1988, bem como a posição da doutrina e do Supremo Tribunal Federal, examinando-se os casos de maior repercussão. Por fim, adentrou-se o conflito de competência entre Estados e Municípios pela tributação do Software como Serviço (SaaS)

A Novel Financial Service Model in Private CloudSaha, Ranjan 14 January 2014 (has links)
In this thesis, we propose architecture for a SaaS model in Cloud that would provide service to the financial investors who are not familiar with various mathematical models. Such finance models are used to evaluate financial instruments, for example, to price a derivative that is currently being traded before entering into a contact. An investor may approach CSP to price a particular derivative and specify the time, budget and accuracy constraints. Based on these constraints specified by investors, the service provider will compute the option value using our proposed FSM. To evaluate our proposed model, we compared pricing results with the classical model that provides a closed-form solution for option pricing to meet the accuracy constraints. After establishing the accuracy of our pricing results, we further ensured that the SLA between the FSP and the investors is honoured by meeting the constraints put forth by the investor who uses the Cloud service.

Comparing frontend frameworks and cloud services by using House of QualityWikhög, Magnus January 2018 (has links)
The objective of this study has been to investigate and compare frontend javascript frameworks and cloud services in order to find which ones are most suitable to implement a web based product development application. The application will be based on the "House of Quality" methodology, which is commonly used in product development. It is basically a way to organize customer requirements, identify relevant quantifiable technical parameters and rank them in order to find out which ones are most important for the finished product. By using this very methodology on the application itself, the most important parameters were found to be data update delays and the need for additional services. The selected cloud services were benchmarked according to these parameters. For framework comparison, the methodology was based on existing research regarding what developers actually base their selection of frontend javascript frameworks on, which resulted in the metrics maturity, community size and documentation. SQL queries and benchmarking scripts were constructed in order to gather statistics from online services and run performance benchmarks. The results reveal substantial differences between frameworks as well as in performance among cloud services. A combination of the frontend framework Angular, the backend service Firebase and the authentication service Auth0 were found to be well suited for fulfilling the requirements of the product development application. Finally, potential problems, ethical considerations and areas where more research is required are discussed.

An empirical study of the transformation of a Node.js based web application, Entize Planning, into a cloud service / En empirisk studie av transformationen av en Node.js baserad webbapplikation, Entize Planning, till en molntjänstLagerman, Rikard January 2014 (has links)
The Node.js based web application Entize Planning needs to evolve and become distributable, and the logical transformation is into a SaaS cloud service that can compete in a pressured economic climate concerning resources. The aim is to provide an insight into the challenges in mitigating a web service to the cloud. By utilising the edge concerning low-cost and rapid development associated with Open Source use, a NoSQL supported and Node.js with related technologies, cloud service prototype development process and environment is proposed. Keeping guidelines such as: security, maintenance, complexity, scalability and mobility; emphasised, in order to carefully utilise existing architecture will result in an flexible solution that preserves aforementioned attributes, making the project as a whole a success towards its endusers. Key remarks that surfaced was the distinct separation between Entize Planning - the product - and the delivery mechanism - the cloud service plattform - and also the explicit need to investigate any utilisation of preexisting cloud architecture pertaining limitations in their delivery, before adoptation.
