Facilitating Self-Adaptable Inter-cloud Management

Abstract

Abstract-Cloud Computing infrastructures have been developed as individual islands, and mostly proprietary solutions so far. However, as more and more infrastructure providers apply the technology, users face the inevitable question of using multiple infrastructures in parallel. Federated cloud management systems offer a simplified use of these infrastructures by hiding their proprietary solutions. As the infrastructure becomes more complex underneath these systems, the situations (like system failures, handling of load peaks and slopes) that users cannot easily handle, occur more and more frequently. Therefore, federations need to manage these situations autonomously without user interactions. This paper introduces a methodology to autonomously operate cloud federations by controlling their behavior with the help of knowledge management systems. Such systems do not only suggest reactive actions to comply with established Service Level Agreements (SLA) between provider and consumer, but they also find a balance between the fulfillment of established SLAs and resource consumption. The paper adopts rule-based techniques as its knowledge management solution and provides an extensible rule set for federated clouds built on top of multiple infrastructures.

Towards Secure Inter-Cloud Architectures

“…The Federated Cloud Management approach in [Kec12a] uses caches inside and outside of the SP. In [15] an external component captures the events from different Cloud Brokers in order to improve the assignment of resources.…”

“…The Inter-Cloud environment has seen several projects [4,6,8,12,13,15] that aim to solve the lack of federation and interoperability capabilities between heterogeneous Service Providers; however, the lack of a reference architecture has led to some of them to propose similar but good solutions worthy of being highlighted. Due to these commonalities we have been able to identify a federated Inter-Cloud pattern which relates the most popular federated Inter-Cloud projects in order to conceptually unify them and to build the basis of a coming secure Inter-Cloud architecture.…”

“…The Clouds are federated forming a dynamic collaboration network for sharing resources using the VO-based component to resolve and assign the best combination of Service Providers.  The Federated Cloud Management project [15] proposed a single point of access to the federation called Generic Meta Broker Service. This component takes care of the submission of a request from the Consumers and worries about matching it with the best possible provider.…”

“…The Generic Meta Broker Service uses external Cloud Brokers for instantiation and to redirect the calls to the Service Providers. In [15] an extra component is included to improve the way the Generic Meta Broker Service makes decisions and matching (the Global Autonomous Manager), by monitoring and analyzing the information arrived from the Cloud Brokers.…”

A broker based approach for cloud provider selection

“…In paper [16] author presents a mechanism to automatically operate cloud federation using knowledge management system. Here author use hybrid KM (knowledge management) system which combines both local and global integration options.…”
