During the last decade, there has been an increased interest on cloud computing and especially on the adoption of public cloud services. The process of developing cloud-based public services or migrating existing ones to the Cloud is considered to be of particular interest—as it may require the selection of the most suitable applications as well as their transformation to fit in the new cloud environment. This paper aims at presenting the main findings of a migration process regarding smart city applications to a cloud infrastructure. First, it summarises the methodology along with the main steps followed by the cities of Agueda (Portugal), Thessaloniki (Greece) and Valladolid (Spain) in order to implement this migration process within the framework of the STORM CLOUDS project. Furthermore, it illustrates some crucial results regarding monitoring and validation aspects during the empirical application that was conducted via these pilots. These findings should be received as a helpful experience for future efforts designed by cities or other organisations that are willing to move their applications to the Cloud.

This paper describes our work on STORM CLOUDS[1], a project with the main objective of migrating smart-city services, that Public Authorities (PAs) currently provided using traditional Information Technology, to a cloud-based environment. Our organization was in charge of finding the technical solutions, so we designed and implemented a cloud computing solution called Storm Clouds Platform (SCP), for that purpose. In principle, the applications we ported could run on a public cloud service, like Amazon Web ServicesTM[2] or Microsoft® Azure[3], that provide computational resources on a pay-per-use paradigm. However, these solutions have disadvantages due to their proprietary nature: vendor lock-in is one of the issues but other serious problems are related to the lack of full control on how data and applications are processed in the cloud. As an example, when using a public cloud, the users of the cloud services have very little control on the location where applications run and data are stored, if there is any. This is identified as one of the most important obstacles in cloud computing adoption, particularly in applications manage personal data and the application provider has legal obligation of preserving end user privacy[4]. This paper explains how we faced the problem and the solutions we found. We designed a cloud computing platform — completely based on open software components — that can be used for either implementing private clouds or for porting applications to public clouds.

Business processes are not only variable they are as well dynamic. A key benefit of Business Process Management (BPM) is the ability to adjust business processes accordingly in response to changing market requirements. In parallel to BPM, enterprise cloud computing technology has emerged to provide a more cost effective solution to businesses and services while making use of inexpensive computing solutions, which combines pervasive, internet, and virtualization technologies (). Despite the slow start, the business benefits of cloud computing are as such that the transition of BPM to the cloud is now underway. Cloud services refer to the operation of a virtualized, automated, and service-oriented IT landscape allowing the flexible provision and usage-based invoicing of resources, services, and applications via a network or the internet. The generic term “X-as-a-Service” summarize the business models delivering almost everything as a service. BPM in the cloud is often regarded as a SaaS application. More recently, BPM is being regarded as a PaaS as it facilitates the creation and deployment of applications, in this case business process solutions. The PaaS landscape is the least developed of the four cloud based software delivery models previously discussed. PaaS vendors, such as IBM, Oracle, and Microsoft delivered an application platform with managed cloud infrastructure services however, more recently the PaaS market has begun to evolve to include other middleware capabilities including process management. BPM PaaS is the delivery of BPM technology as a service via a cloud service provider. For the classification as a PaaS a BPM suite requires the following capabilities: the architecture should be multi-tenant, hosting should be off premise and it should offer elasticity and metering by use capabilities. When we refer to BPM in the cloud, what we are really referring to is a combination of BPM PaaS and BPaaS (Business Process as a Service). Business Process as a Service (BPaaS) is a set of pre-defined business processes that allows the execution of customized business processes in the cloud. BPaaS is a complete pre-integrated BPM platform hosted in the cloud and delivered as a service, for the development and execution of general-purpose business process application. Although such a service harbors an economic potential there are remaining questions: Can an individual and company-specific business process supported by a standardized cloud solution, or should we protect process creativity and competitive differentiation by allowing the company to design the processes individually and solely support basic data flows and structures? Does it make sense to take a software solution “out of the box” that handles both data and process in a cloud environment, or would this hinder the creativity of business (process) development leading to a lower quality of processes and consequently to a decrease in the competitive positioning of a company? How to manage the inherent compliance and security topic. Within a completely integrated business application system, all required security aspects can be implemented as a safeguarding with just enough money. Within the cloud, however, advanced standards and identity prove is required to monitor and measure information exchange across the federation. Thereby there seems to be no need for developing new protocols, but a standardized way to collect and evaluate the collected information.

The article is devoted to the analysis of modern approaches that ensure the security of cloud services. Since cloud computing is one of the fastest growing areas among information technology, it is extremely important to ensure the safety and reliability of processes occurring in the clouds and to secure the interaction between the client and the provider of cloud services. Given that fears about data loss and their compromise are one of the main reasons that some companies do not transfer their calculations to the clouds. The object of research and analysis of this work are cloud services, which are provided by various cloud service providers. The aim of the study of this work is to compare existing approaches that provide information security for cloud services, as well as offer a new approach based on the principle of diversity. There are many approaches that ensure their safety, using both traditional and cloud-specific. The multi-cloud approach is one of the most promising strategies for improving reliability by reserving cloud resources on the servers of various cloud service providers. It is shown that it is necessary to use diversity to ensure the reliability and safety of critical system components. The principle of diversity is to use a unique version of each resource thanks to a special combination of a cloud computing provider, the geographical location of data centers, cloud service presentation models, and cloud infrastructure deployment models. The differences between cloud providers and which combination of services are preferable to others in terms of productivity are discussed in detail. In addition, best practices for securing cloud resources are reviewed. As a result, this paper concludes that there is a problem of insufficient security and reliability of cloud computing and how to reduce threats in order to avoid a common cause failure and, as a result, loss of confidential data or system downtime using diversity of cloud services.

The current problem of transition to the use of "Cloud Computing" in the process of assessing possible use has been reflected in this study. Assessments of the capabilities of cloud services have been conducted, which are part of a group study of cloud computing as a platform for creating a communication environment in the scientific activities of the Free Economic Zone. The essence of the concept of cloud computing is to provide end users with remote dynamic access to services, computing resources and applications via the Internet. The main possibilities and functions of the information space of scientific communications have been considered. In the process of evaluating the possible use of cloud solutions, the main properties, capabilities and characteristics have also been considered. Web-services based on cloud computing technology in terms of meeting the goals of the scientific community have been analyzed. The most widely used and widely used cloud storage services today that can be used to build a research communication platform are cloud infrastructure providers Google, Amazon and Microsoft. When using the capabilities of these services, favorable conditions are created for the translation of all necessary functions into cyberspace. Today, no more than 37% of domestic organizations actually use cloud technologies to optimize their IT infrastructures, although the COVID-19 pandemic has significantly accelerated this process. Experts claim that Cloud Computing opens access to powerful resources, as well as provides a real opportunity to overcome the technological gap that separates Ukraine from more developed countries. With the successful implementation of such a transition, it is possible to organize a platform of communication environment with new features that meet modern requirements for safety and ease of use in scientific activities. Thus, "cloud computing" is a new approach that reduces the complexity of IT systems, through the use of a wide range of efficient technologies, self-managed and available on demand within the virtual infrastructure, as well as consumed as services.

Cloud computing migrations are increasing rapidly. The main influencing factor being IT management costs. IoT-based enterprises that started their cloud journey by setting up small private clouds within their enterprise have often found that as the applications and services they use broaden. Then the shift towards incorporating public clouds becomes inevitable. The current problem that many of these firms are encountering is the difficulty of managing multiple clouds that reside within different vendors running on different platforms, computational requirements, and vendor SLAs. Lack of support for a single standard for an overall multi-cloud hybrid model exposes the hybrid IT-management to further threats. This makes it difficult for an adopting enterprise to manage and maintain its cloud-based systems during peak performance hours, which often leads to system downtime. This chapter discusses various SLA issues specific to a hybrid multi-cloud environment and suggests possible solutions to help adopting firms in their management.
