Aspects of the present invention disclose a method, computer program product, and system for monitoring a health status of a computing system. The method includes one or more processors deploying a respective monitoring prediction agent in each of a plurality of worker nodes of a computing system. The method further includes determining, for each of the plurality of worker nodes by the respective monitoring prediction agent, a single binary health status value by comparing a time-dependent function of performance metric data values of the respective worker node to upper and lower threshold values. The method further includes receiving the binary health status values together with respective identity information from each of the plurality of worker nodes. The method further includes generating a dataset indicative of a health status of the computing system by feeding the received respective identity information to hash functions of a Counting Bloom Filter.

Monitoring health status of a large cloud computing system

A method for enhancing a service delivery system with a multi-staged broker may be provided. The multi-staged broker may be suited for a placement of a service. The delivery system accesses at least two infrastructure systems offering services for deploying service resources. The at least two infrastructure systems are operated by different service providers. The method comprises collecting static and dynamic capabilities of the two infrastructure computing systems, combining the static capabilities and the dynamic capabilities for determining a first most suitable infrastructure system for deploying a service requiring a computing environment satisfying attribute values of a service capability profile, deploying the service on the first most suitable infrastructure system. The method comprises also receiving an event indicative of a change, reassessing most suitable infrastructure system and repeating the combining for determining a second most suitable infrastructure system, and redeploying the service on the second most suitable infrastructure system.

Hybrid cloud broker with static and dynamic capability matching

The present embodiment may include a computing system that may extract a plurality of metadata from a service contract (human readable document) that was signed between the cloud infrastructure provider and a service owner before the service is deployed on the service delivery system of the cloud infrastructure provider. The present embodiment may compile the plurality of metadata into a control component that is an executable program that may be compiled with the service and adopted for auditing and enforcing the service contract of the service. The present embodiment may cause the service owner to compile the service with the control component, where the control component enabling auditing and enforcing the service contract signed for the service and monitors the service at runtime for compliance with the service contract.
