Abstract:
Choosing the best configuration to deploy a distributed application in a multi-cloud environment is a complex task since many cloud providers offer several services with different capabilities. In this paper, we present a multi-cloud selection process to deploy a distributed microservice-based application, which has low communication cost among microservices. The proposed selection process is part of PacificClouds, an approach that intends to manage the deployment and execution of distributed applications across multiple providers from the software architect perspective. The proposed approach selects various providers, where each provider must host an entire microservice with multiple tasks consuming several cloud services. The UM2Q approach selects the provider that better meets the software architect requirements, for each microservice of a multi-cloud application. Hence, the proposed process of selecting multiple providers uses multi-criteria decision-making methods to rank the cl
oud services and selects cloud providers and services by individually observing each microservice requirement, such as cloud availability, response time, and cost. Further, we propose a formal description of UM2Q and a brief one of the strategy implementation. We also introduce a set of experiments to evaluate UM2Q performance, and the outcomes showed its feasibility for a variable number of requirements, microservices and providers, even for extreme values.
