**E-service Quality and Development**

Chapter 7 presents a comparative study on public electronic employment services in Austria, Spain, Estonia, and Romania. This chapter analyzes public employment services in four European countries to identify the extent to which they have adapted to the global pandemic situation. Measures to protect jobs and support workers in identifying new jobs are a permanent concern for most countries. The emphasis is on the workers' protection in digitalization and e-service implementation.

Chapter 8 proposes network function virtualization over cloud–cloud computing as a business continuity solution. It discusses cloud computing as a business continuity solution and cloud service availability. It also examines the causes of service unavailability and related impacts. Further, this chapter covers various ways to achieve the required cloud service availability. It explores the importance of business continuity in a cloud environment and how business continuity enables achieving the required service availability. Finally, this chapter discusses various challenging issues of cloud infrastructure and data protection solutions.

Chapter 9 presents issues of e-service quality factors. It provides recommendations for different players' roles in e-services, along with definitions, components, and characteristics through studies of examination about the perspective of providers and users of government e-services. The chapter proposes eight quality dimensions for government e-service.

The last chapter presents book reviews of ICT project aspect case studies. The chapter explores different ICT development aspects and discovers important e-service issues. It has written for supporting International Federation of Automatic Control (IFAC), Technical Committee 9.5, Working Group WG 03.

Very few e-service books address concepts and practical recommendations through case studies, which is significant as a considerable portion of e-service needs to be between businesses and users. This book "Digital Service Platforms" is a comparatively rational approach with strategic support for e-service professionals and academic researchers.
