COSTA: A cost-driven solution for migrating applications in multi-cloud environments
Leandro Costa da Silva, Robson Wagner Albuquerque de Medeiros, Nelson Souto Rosa · 2023
This paper focuses on the runtime replacement of microservice-based applications (MBAs), considering cost aspects. Several existing solutions also focus on replacement issues, but they usually concentrate on performance aspects and do not consider cost in the decision-making process. This paper presents COSTA (COST management and Adaptive system), a solution that monitors public clouds' costs and manages the migration of applications between them, considering the application's budget and execution cost. Several experiments were conducted to assess the solution, looking for scenarios ideal for evaluating a migration among clouds. In the end, COSTA effectively reduced the cost of applications through cloud providers migration.
