Application Performance Management in Virtualized Server Environments
TL;DR: This paper introduces the concept of server consolidation using virtualization and point out associated issues that arise in the area of application performance, and shows how some of these problems can be solved by monitoring key performance metrics and using the data to trigger migration of virtual machines within physical servers.
Patent
Methods and apparatus for managing dependencies in distributed systems
TL;DR: In this paper, techniques for managing runtime dependencies between the various components of computing systems are disclosed which provide a level of abstraction from individual systems and allow the computation of service/component dependencies that are related to end-to-end services, as perceived by a customer.
Proceedings ArticleDOI
An active approach to characterizing dynamic dependencies for problem determination in a distributed environment
TL;DR: The methodology relies on active perturbation of the system to identify dependencies and the use of statistical modeling to compute dependency strengths and considers how the dependencies computed by the approach can be used to simplify and guide the task of root-cause analysis, an important part of problem determination.
Patent
Systems and methods for service and role-based software distribution
TL;DR: In this paper, a base software package is prepared for each of the one or more regions based on at least one of: (i) policy data indicating which regions are candidates for receiving the software package, (ii) dependency information indicating requisites for a service provided by the software packages, and (iii) configuration information for each candidate regions.
Patent
Systems, methods and computer programs for determining dependencies between logical components in a data processing system or network
TL;DR: In this article, a dependency generator identifies correlations between the run-time activity of the monitored components, and a weighting is computed for each dependency relationship based on the consistency of containment.
