A key aspect of framing cloud datacenters Service Level Agreements is the derivation of downtime probability distribution function of a set of provisioned servers over a service window. This is further complicated by the hierarchy of power, network and server domains within any datacenter. This hierarchy adds significant complexity in the estimation of transient distributions. The process of fa...

The rapid increase in digital content, specially multimedia, calls now for standardization of Media Cloud and Inter-Cloud computing, for better provisioning of services. InterCloud computing faces some key challenges in terms of handling multimedia, which are discussed in this paper along with our research status towards their solutions. We also present InterCloud basic architecture and Media C...

Cloud computing is a phenomenal distributed computing paradigm that provides flexible, low-cost ondemand data management to businesses. However, this so-called outsourcing of computing resources causes business data security and privacy concerns. Although various methods have been proposed to deal with these concerns, none of these relates to multi-clouds. This paper presents a practical data m...

Cloud computing is one of the Information Communication Technology (ICT) trends. It is amalgamation of network of computers connected by centralized physical server. These servers are located on remote computers so that we can access applications directly from distant computer by sitting at our place. The paper makes readers aware of concepts of cloud computing along with its architecture. Few ...

Failure detectors are used to build high availability distributed systems as the fundamental component. To meet the requirement of a complicated large-scale distributed system, accrual failure detectors that can adapt to multiple applications have been studied extensively. However, several implementations of accrual failure detectors do not adapt well to the cloud service environment. To solve ...

Recent years have seen significant growth in the cloud computing market, both in terms of provider competition (including private offerings) and customer adoption. However, the cloud computing world still lacks adopted standard programming interfaces, which has a knock-on effect on the costs associated with interoperability and severely limits the flexibility and portability of applications and...

Mobile cloud computing (MCC) is a new technology that has been developed to overcome the restrictions of smart mobile devices (e.g. battery, processing power, storage capacity, etc.) to send a part of the program (with complex computing) to the cloud server (CS). In this paper, we study a multi-cell with multi-input and multi-output (MIMO) system in which the cell-interior users request service...

Recently, fog computing has been introducedto solve the challenges of cloud computing regarding Internet objects. One of the challenges in the field of fog computing is the scheduling of tasks requested by Internet objects. In this study, a review of articles related to task scheduling in fog computing has been done. At first, the research questions and goals will be introduced, an...

loud computing’s unique features, including the low capital investment, reduced total cost of ownership, high availability, elastic scalability, and lower complexity compared to traditional high-performance computing models, have made it the predominant ICT platform over the last few years. The cloud is rapidly being adopted in numerous domains worldwide, including education, healthcare, commer...

The global competition have extended the scope of trade and supply chains causing information management to be an essential part businesses. Many new technologies recently been adapted by organizations in era digitalization. Cloud computing had important place these has integrated widely organizations. In recent days unexpected risky periods such as pandemic increased interest towards cloud top...
