Cloud systems are complex and large systems where services provided by different operators must coexist and eventually cooperate. In such a complex environment, controlling the health of both the whole environment and the individual services is extremely important to timely and effectively react to misbehaviours, unexpected events, and failures. Although there are solutions to monitor cloud systems at different granularity levels, how to relate the many KPIs that can be collected about the health of the system and how health information can be properly reported to operators are open questions. This paper reports the early results we achieved in the challenge of monitoring the health of cloud systems. In particular we present CloudHealth, a model-based health monitoring approach that can be used by operators to watch specific quality attributes. The CloudHealth Monitoring Model describes how to operationalize high level monitoring goals by dividing them into subgoals, deriving metrics for the subgoals, and using probes to collect the metrics. We use the CloudHealth Monitoring Model to control the probes that must be deployed on the target system, the KPIs that are dynamically collected, and the visualization of the data in dashboards.

Self-healing and SDN: bridging the gap

Nowadays, cloud computing is becoming popular within the business environment. Cloud services is not new, but the evolution of mobility, connectivity, and computing hardware has made it interesting for the business. Cloud services provides a way to increase the capacity or add capabilities dynamically without investing in new IT infrastructure, training new personnel, or licensing new software. Focusing on the consumer product goods (CPG) market with its mainly small and medium-sized companies, we see dramatic changes from the market demands, logistic challenges and price competition. The purpose of this chapter is therefore to present the positioning of cloud services in the CPG industry and to outline an approach that enables a typical company in the CPG industry to link the current capabilities of cloud services this to a business-process-driven evaluation approach to provide a transparency for the decision towards cloud services. The result of the business process investigation underlies assumptions and inductive conclusions.

Service Specific Overlay Networks have recently attracted a great interest, and have been extensively investigated in the context of multimedia delivery over the internet. they are virtual networks constructed on top of the underlying network and they have been proposed to provide and improve services not provided by other traditional networks to the end users. The increased complexity and heterogeneity of these networks in addition to ever changing conditions in the network and the different types of faults that may occur make their control and management by human administrators more difficult. Therefore, self-healing concept was introduced to handle these changes and to assure highly reliable and dependable network system performance. Self-healing aims at ensuring that the service will continue to work regardless of defects that might occur in the network. This paper introduce literature in the area of self-healing overlay networks, present their basic concepts, requirements, and architectures. In addition to that we present a proposed self-healing architecture for multimedia delivery services. Our proposed solution is oriented to discover new approaches for monitoring, diagnosing, and recovering of services thus achieving self-healing.

Service Specific Overlay Networks (SSONs) have recently attracted a great interest, and have been extensively investigated in the context of multimedia delivery over the internet. SSONs are virtual networks constructed on top of the underlying network and they have been proposed to provide and improve services not provided by other traditional networks to the end users. The increased complexity and heterogeneity of these networks in addition to ever changing conditions in the network and the different types of fault that may occur make their control and management by human administrators more difficult.
