“…This is aimed at customers with demands not supported by the cloud providers and SPA can again reduce the overhead and costs of SpotCheck. SuperCloud [11] is a cloud architecture running over OpenStack integrating multiple cloud providers and allowing for live migration across those providers using Xen virtualization. Supercloud uses nested virtualization to enable complete VM migration from one server to another, allowing users to relocate virtual machines from one cloud provider to another without disrupting the running application.…”

Amazon Web Services (AWS) offers transient virtual servers at a discounted price as a way to sell unused spare capacity in its data centers. Although transient servers are very appealing as some instances have up to 90% discount, they are not bound to regular availability guarantees as they are opportunistic resources sold on the spot market. In this paper, we present SPA, a framework that remarkably increases the spot instance reliability over time due to insights gained from the analysis of historical data, such as cross-region price variability and intervals between evictions. We implemented the SPA reliability strategy, evaluated them using over one year of historical pricing data from AWS, and found out that we can increase the transient instance lifetime by adding a pricing overhead of 3.5% in the spot price in the best scenario.

“…Our method is non-monetary, in contrast to monetary spot markets used now to trade excess, short-term CSP capacity by some providers [7]. A client could use spot instances to dynamically migrate between CSPs [6].…”

In a hybrid cloud, individual cloud service providers (CSPs) often have incentive to use each other's resources to offload peak loads or place load closer to the end user. However, CSPs have to keep track of contributions and gains in order to disincentivize long-term free-riding. We show CloudShare, a distributed version of a load balancing algorithm DirectCloud based on the Shapley value-a powerful fairness concept from game theory. CloudShare coordinates CSPs by a ZooKeeper-based coordination layer; each CSP runs a broker that interacts with local resources (such as Kubernetes-managed clusters). We quantitatively evaluate our implementation by simulation. The results confirm that CloudShare generates on the average more fair schedules than the popular FairShare algorithm. We believe our results show an viable alternative to monetary methods based on, e.g., spot markets.
