Dynamic Test Agent Placement in Cloud Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud service providers offer limited control over the placement of test agents within virtual processing environments, leading to unnecessary resource allocation and costs, as well as potential relocation of processing nodes that are undesirable for testing purposes.
Innovation Solution
A method and system for dynamically deploying test agents based on deployment information within cloud environments, allowing for precise placement of test agents in specific server zones, geographic locations, or data centers, and enabling intelligent management of test agent resources to match testing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If test agents are pre-deployed with each application in cloud environments, then testing coverage is ensured, but resource allocation costs increase unnecessarily
Solution Approach 1:
The test agent deployment system transitions from static pre-deployment to dynamic on-demand deployment. The test controller receives deployment information from the cloud management controller, analyzes it to determine optimal test agent locations, and dynamically provisions test agents only when needed for specific testing scenarios. This dynamic approach ensures testing coverage while avoiding unnecessary resource allocation.
Solution Approach 2:
The system performs preliminary analysis of cloud resource deployment information before deploying test agents. The test controller receives and analyzes deployment information about applications and processing nodes, determining in advance the optimal locations for test agent deployment. This preliminary action enables targeted resource allocation rather than blanket pre-deployment across all locations.
2Productivity
If cloud management controller relocates processing nodes for load balancing, then resource utilization is optimized, but test agent placement becomes unpredictable
Solution Approach 1:
The system establishes a feedback loop where the test controller continuously receives deployment information from the cloud management controller about processing node locations and application deployments. This feedback mechanism allows the test controller to adapt test agent placement to the current state of the cloud environment, maintaining control over test agent locations even as the cloud management controller relocates processing nodes for load balancing.
Solution Approach 2:
The test controller performs preliminary analysis of deployment information to determine optimal test agent locations before test execution. By analyzing the current state of processing nodes and applications, the system proactively positions test agents in appropriate locations, ensuring test agent placement control is maintained despite cloud management controller activities.
3Reliability
If test agents are deployed across diverse geographic locations, then service resiliency is improved, but deployment complexity increases
Solution Approach 1:
The test controller serves multiple functions: receiving deployment information from the cloud management controller, analyzing deployment information to determine test agent locations, provisioning test agents at appropriate locations, and coordinating testing across diverse geographic locations. This universal test controller simplifies the overall deployment complexity by consolidating multiple functions into a single coordinating system.
Solution Approach 2:
The test controller acts as an intermediary between the cloud management controller and test agents. It receives deployment information from the cloud management controller, processes this information to determine optimal test agent locations, and then provisions test agents accordingly. This intermediary role simplifies the coordination of test agent deployment across diverse geographic locations by providing a central point of control.

AI summary
Systems and methods are disclosed for location based deployment of test agents in a cloud environment based upon deployment information for previously placed customer processing nodes. The cloud environment is hosted by servers operating to provide cloud services within two or more server zones. A test controller receives deployment information about applications operating with the cloud environment, analyzes the deployment information to determine locations within the cloud environment for deployment of test agents where the locations are associated with a plurality of the applications, sends resource requests to a cloud management controller to deploy the test agents at the locations, and receives test results from the test agents deployed by the cloud management controller at the locations based upon the resource requests. Monitor agents operating along with applications deployed in the cloud can also be used to provide the deployment information to the test controller.
