Pricing cloud IaaS computing services
The economics of cloud computing has recently attracted increasing attention. In particular, a topic which is still under debate is how prices charged to customers for cloud resources are formed, since alternative pricing rules could be considered. Based on three pricing schemes inspired by those used by Amazon EC2, the main global cloud service provider, in the paper we address two main issues. First we present a methodology for the relevant parameters of the pricing rules to be determined in an optimal way, that is to maximise the provider’s revenue. Moreover, we discuss reasons for co-existence of three pricing rules, rather than fewer, to access the cloud. Our findings suggest that this may be due to a larger coverage of the potential demand, since customers applying for cloud services vary in their willingness to pay for the job, the time length of the service, the computational power requested etc. Furthermore, the pricing rule in the so-called, spot market, can provide the platform with useful information on the customers willingness to pay for cloud services. This is because in the spot market users offer a price for service, but pay less than that if their request is satisfied.

Beginning serverless computing : developing with Amazon web services, Microsoft Azure, and Google Cloud
Learn the basics of serverless computing and how to develop event-driven architectures with the three major cloud platforms: Amazon Web Services, Microsoft Azure, and Google Cloud. This hands-on guide dives into the foundations of serverless computing, its use cases, and how to apply it using developer tools such as Node.js, Visual Studio Code, Postman, and Serverless Framework. You will apply the fundamentals of serverless technology from the ground up, and come away with a greater understanding of its power and how to make it work for you. This book teaches you how to quickly and securely develop applications without the hassle of configuring and maintaining infrastructure. You will learn how to harness serverless technology to rapidly reduce production time and minimize your costs, while still having the freedom to customize your code, without hindering functionality. Upon completion, you will have the knowledge and resources to build your own serverless application hosted in AWS, Azure, or Google Cloud and will have experienced the benefits of event-driven technology for yourself. What you'll learn: Gain a deeper understanding of serverless computing and when to use it ; Use development tools such as Node.js, Postman, and VS code to quickly set up your serverless development environment and produce applications ; Apply triggers to your serverless functions that best suit the architecture for the problem the functions are solving ; Begin building applications across cloud providers that utilize the power of serverless technology ; Understand best development practices with serverless computing to maintain scalable and practical solutions ; Code with an agnostic approach to cloud providers to minimize provider dependency. these areas.

Factors affecting the adoption of cloud services in enterprises
Cloud computing services offer enterprise clients many advantages such as reduced costs, easy maintenance and the easy re-provisioning of resources, thus contributing to increased profits. However, little is known about the adoption behavior of such services among enterprises. This study applies the technology–organization–environment framework to investigate determinants of cloud computing service adoption behavior. Data collected from 102 valid enterprises in Taiwan provide strong support for the model. Results indicate that technological (i.e., relative advantage, observability and security), organizational (i.e., financial costs and satisfaction with existing IS) and environmental (i.e., competition intensity) factors were positively related to intention to adopt cloud computing services, accounting for 52 % of variance. Implications and limitations are discussed.

Dynamic performance isolation management for cloud computing services
Unmanaged resource contention in cloud computing environments can cause problems such as performance interference, service quality degradation, and consequently service agreements violation. Performance isolation is an indispensable remedy solution for the mentioned challenges. Dynamic analysis and monolithic management of the performance isolation from the perspective of cloud computing services with different operating entities is a challenging problem. This issue has not been addressed in previous studies, despite its significance. Most previous researches have focused on particular algorithms and methods for specific application scenarios, and lack sufficient descriptions about analysis and management aspects of the performance isolation. Due to the importance of this issue, this paper aims to make an in-depth investigation of this problem and propose a novel approach in order to dynamic analysis and management of the performance isolation for cloud computing services. Proposed approach employs a novel architectural framework, named DPIM, which enables service providers to realize different isolation methods and enforces performance isolation transparently. The experimental results demonstrate the practicality and effectiveness of the proposed approach and related framework for performance isolation management in different service environments, with different operating entities.

SME Cloud Adoption in Botswana: Its Challenges and Successes
The standard office or business in Botswana hosts their resources in-house. This means that a company will have their hardware, software and support staff as part of their daily work operations. Technology has brought a shift to the office environment with Cloud Computing. Botswana has seen the growth of the Cloud Technologies, within its own boundaries where companies have embraced the new technology to mobilize and push their operational agenda with the same tenacity as the rest of the world using the technology. Cloud computing has taken root in Botswana and it shows that a lot of SMEs are using cloud computing, whilst some are non-adopters to the technology. Edgar Tsimane reported the take up on cloud computing in Botswana. Botswana uses the National ICT policy to guide on technological advances and development, i.e the Maitlamo policy. This paper is considering aspects influencing the company’s decisions on utilizing the cloud as a service, both opportunistic and challenges. Some of the questions to address for the study are: how effective is cloud computing for businesses in Botswana; what challenges and successes these companies have had, is there any particular framework they had to follow to guide them in adopting the services? Finally, the paper was to take consideration in recommending a framework that can be adopted within the Botswana.

A survey on security challenges in cloud computing: issues, threats, and solutions
Cloud computing has gained huge attention over the past decades because of continuously increasing demands. There are several advantages to organizations moving toward cloud-based data storage solutions. These include simplified IT infrastructure and management, remote access from effectively anywhere in the world with a stable Internet connection and the cost efficiencies that cloud computing can bring. The associated security and privacy challenges in cloud require further exploration. Researchers from academia, industry, and standards organizations have provided potential solutions to these challenges in the previously published studies. The narrative review presented in this survey provides cloud security issues and requirements, identified threats, and known vulnerabilities. In fact, this work aims to analyze the different components of cloud computing as well as present security and privacy problems that these systems face. Moreover, this work presents new classification of recent security solutions that exist in this area. Additionally, this survey introduced various types of security threats which are threatening cloud computing services and also discussed open issues and propose future directions. This paper will focus and explore a detailed knowledge about the security challenges that are faced by cloud entities such as cloud service provider, the data owner, and cloud user.
