“…In order to benefit from the reliability of unstructured overlays and the efficiency of unicast in structured ones, several studies focus on hybrid overlays. T-Man [7] and Fluidify [21] are examples where structured overlays are created as a result of filtering information which comes from gossiping. T-Man provides a generic interface which can be used to create structured overlays based on custom criteria.…”

“…Topology-aware overlay construction consists in choosing logical neighbours according to their physical proximity. Fluidify [21] follows this path: it updates the logical identifiers according to the identifiers of physically close nodes. A similar technique is used by Vivaldi [4], but for placing nodes in a Cartesian space according to latencies experienced between nodes.…”

Current cloud computing infrastructures and their management are highly centralized, and therefore they suffer from limitations in terms of network latency, energy consumption, and possible legal restrictions. Decentralizing the Cloud has been recently proposed as an alternative. However, the efficient management of a geographically dispersed platform brings new challenges related to service localization, network utilization and locality-awareness. We here consider a cloud topology composed of many small datacenters geographically dispersed within the backbone network. In this paper, we present the design, development and experimental validation of Koala, a novel overlay network that specifically targets such a geographically distributed cloud platform. The three key characteristics of Koala are laziness, latencyawareness and topology-awareness. By using application traffic, Koala maintains the overlay lazily while it takes locality into account in each routing decision. Although Koala's performance depends on application traffic, through simulation experiments we show that for a uniformly distributed traffic, Koala delivers similar routing complexity and reduced latency compared to a traditional proactive protocol, such as Chord. Additionally, we show that despite its passive maintenance, Koala can appropriately deal with churn by keeping the number of routing failures low, without significantly degrading the routing performance. Finally, we show how such an overlay adapts to a decentralized cloud composed of multiple small datacenters.

Recent increase in demand for next-to-source data processing and low-latency applications has shifted attention from the traditional centralized cloud to more distributed models such as edge computing. In order to fully leverage these models it is necessary to decentralize not only the computing resources but also their management. While a decentralized cloud has various inherent advantages, it also introduces different challenges with respect to coordination and collaboration between resources. A large-scale system with multiple administrative entities requires an overlay network which enables data and service localization based only on a partial view of the network. Numerous existing overlay networks target different properties but they are built in a generic context, without taking into account the specific requirements of a decentralized cloud. In this paper we identify some of these requirements and introduce Koala, a novel overlay network designed specifically to meet them.

Many decentralized online social networks (DOSNs) have been proposed due to an increase in awareness related to privacy and scalability issues in centralized social networks. Such decentralized networks transfer processing and storage functionalities from the service providers towards the end users. DOSNs require individualistic implementation for services, (i.e., search, information dissemination, storage, and publish/subscribe). However, many of these services mostly perform social queries, where OSN users are interested in accessing information of their friends. In our work, we design a socially-aware distributed hash table (DHTs) for efficient implementation of DOSNs. In particular, we propose a gossip-based algorithm to place users in a DHT, while maximizing the social awareness among them. Through a set of experiments, we show that our approach reduces the lookup latency by almost 30% and improves the reliability of the communication by nearly 10% via trusted contacts.
