This chapter describes the error recovery mechanisms in the system handling the Grid-based workflow within the Service Level Agreement (SLA) context. It classifies the errors into two main categories. The first is the large-scale errors when one or several Grid sites are detached from the Grid...

Within this paper, we present the GridEcon Platform, a testbed for designing and evaluating economics-aware services in a commercial Cloud computing setting. The Platform is based on the idea that the exact working of such services is difficult to predict in the context of a market and,...

In this paper, we present agent-based simulations that model the interactions between software buyers and vendors in a software market that offers Software-as-a-Service (SaaS) and perpetual software (PS) licensing under different pricing schemes. In particular, scenarios are simulated, in which...

Dynamic processes in complex networks have received much attention. This attention reflects the fact that dynamic processes are the main source of changes in the structural properties of complex networks (e.g., clustering coefficient and average shortest-path length). In this paper, we develop...

Are students from one of the high tech universities in the world fully aware of their permanent linkage to the global learning network, the World Wide Web? In their pockets, backpacks, and purses are the latest smartphones loaded will countless apps. But, how aware are these students of the use...

Can education problems in poor countries be successfully addressed using knowledge economics? The old development model posits that poor countries must follow the route of richer countries, progressing up a scale of development. But an emerging theory of development and collective adaptive...

Shortcomings of transport network technologies were the main driver behind strong efforts of standardization organizations to develop control plane frameworks since 2001. Despite the findings of previous studies that the control plane framework deployment will lead to a 50 percent decrease in...

Many IT service platforms (e.g., cloud computing platforms) are built as closed systems. They do not allow their customers to interoperate with other platforms or port their data to other platforms. As switching to different system is costly, customer of a closed IT system can be considered...

Several Cloud computing business models have been developed and implemented, including dynamic pricing schemes. This paper extends the known concepts of revenue management to the specific case of Cloud computing from two perspectives. First, we propose system architecture for Cloud service...

Due to the large variety in computing resources, Cloud markets often suffer from a low probability of finding matches between consumers' bids and providers' asks, resulting in low market liquidity. The approach of SLA templates (i.e., templates for electronic contracts) is a means to reduce this...
