Table 1 Summary of resource management definitions, actors, and QoS/SLA aspects considered in each definition

From: Cloud resource management: towards efficient execution of large-scale scientific applications and workflows on complex infrastructures

Work Summary Actors QoS SLA
[108] Three phases: provisioning, scheduling, monitoring Cloud provider (infra. and workload mgmt.) and cloud consumer (end user) Yes Yes
[52] Organized in three tiers (one per role) and a total of 15 different stages, including scheduling, provisioning, pricing, profiling, and monitoring. Cloud provider (infra. mgmt.), cloud user (broker), end user (execute workload) Yes Yes
[72] Nine components: provisioning, allocation, adaptation, mapping, modeling, estimation, discovery, brokering, and scheduling No specific actors are identified; implicit assumption of at least two roles: cloud provider and cloud user Yes No
[80] Two tasks: procurement and release of resources. Two objectives: performance isolation and efficient use of hardware. Seven metrics: energy, SLA, load, network load, profit, hybrid clouds, and mobile clouds. No specific actors are identified; implicit assumption of at least two roles: cloud provider and cloud user No Yes
[75] Three aspects affected: performance, functionality, and cost. Five policy classes: admission control, capacity allocation, load balancing, energy optimization, and QoS. Cloud provider and cloud user. Yes No
[125] Predicting workload to enable workload consolidation while meeting SLAs. No specific actors Yes Yes
[69] Two main activities: matching and scheduling. No specific actors Yes Yes
