As more and more service providers choose Cloud platforms, which is provided by third party resource providers, resource providers needs to provision resources for heterogeneous workloads in different Cloud scenarios. Taking into account the dramatic differences of heterogeneous workloads, can we coordinately provision resources for heterogeneous workloads in Cloud computing? In this paper we f...

Cloud technology connects a collection of virtualized computers that are dynamically provisioned as computing resources, based on negotiated agreements between service providers and users. It delivers information technology resources in diverse forms of service, and the explosion of Cloud services on the Internet brings new challenges in Cloud service discovery and selection. To address these c...

4 Abstract—Cloud computing has recently emerged as an important service to manage applications efficiently over the Internet. Various 5 cloud providers offer pay per use cloud services that requires Quality of Service (QoS) management to efficiently monitor and measure 6 the delivered services through Internet of Things (IoT) and thus needs to follow Service Level Agreements (SLAs). However, pr...

Welcome to the special issue of Concurrency and Computation: Practice and Experience (CCPE) journal. This special issue compiles a number of excellent technical contributions that significantly advance the state-of-the-art in the areas of orchestrating cloud resources, composing new cloud services from existing ones, increasing energy efficiency via cloud resource orchestration, and developing ...

Federation of Cloud services is notably landing interests from both Cloud providers and consumers. Cloud providers nowadays are required to form federations to remain competitive, and sustain their market share. Cloud consumers however seek optimized services from Clouds federation. They strive to maximize their satisfaction level, which is often measured by Quality of Service (QoS). Federation...

In the future, the Cloud will evolve into a rich ecosystem of service providers and consumers, each building upon the offerings of others. Cloud service brokers will play an important role, mediating between providers and consumers. As well as providing vertical integration and value-added aggregation of services, brokers will play an increased role in continuous quality assurance and optimizat...

Cloud computing allows customers to utilise IT services in a pay-asyou-go fashion to save huge cost on IT infrastructure. In open cloud, ‘malicious’ service providers could record service data from a cloud customer and collectively deduce the customer’s privacy without the customer’s permission. Accordingly, customers need to take certain actions to protect their privacy automatically at client...

Developing and deploying Service-based Applications (SBAs) using different Software-as-a-service (SaaS), Platform-as-a-service (PaaS) and Infrastructure-as-a-service (IaaS) offerings from multiple providers in the cloud is still not possible, since current cloud service offerings are often provided as monolithic, one-size-fits-all solutions and give little or no room for customization. This lim...

The Cloud Computing paradigm has gained considerable attention owing to the notable commercial success of many Cloud service providers. Typically, a Cloud Computing service provides its customers with resources as a utility, using a pay-as-you-go model. Thus, Cloud Computing customers can reduce costs related to the acquisition and management of complex IT infrastructures, and Cloud service pro...

Cloud computing is a paradigm that has the potential to transform and revolutionalize the next generation IT industry by making software available to end-users as a service. A cloud, also commonly known as a cloud network, typically comprises of hardware (network of servers) and a collection of softwares that is made available to end-users in a pay-as-you-go manner. Multiple public cloud provid...
