Patent number: 11237806Abstract: A system, computer program product, and method are provided for orchestrating a multi objective optimization of an application. A set of two or more key performance indicators (KPIs) and one or more parameters associated with the application are received. A machine learning (ML) based surrogate function learning model in combination with an acquisition function is leveraged to conduct one or more adaptive trials. Each trial consists of a specific configuration of the one or more parameters. A pareto surface of the KPIs of the application is computed based on the observations of KPI values from each adaptive trial. The pareto surface is explored and an optimal operating point is selected for the application. The application is then executed at the selected operating point.Type: GrantFiled: April 30, 2020Date of Patent: February 1, 2022Assignee: International Business Machines CorporationInventors: Srinivasan Parthasarathy, Fabio A.

Patent number: 11184241Abstract: A method and system of determining a health state of a microservice based application includes extracting traces of multiple variants of a microservice-based application. Topologies of the multiple variants are inferred based on the extracted traces. One or more topological differences of each of the multiple variants are identified based on the extracted traces. Each topological difference is ranked. The topological differences of the microservice-based application are displayed on a user interface, including a microservice map of the topological differences and a listing of a top ranking of the topological differences.Type: GrantFiled: February 8, 2019Date of Patent: November 23, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Gerald Schermann, Fabio A.
