CloudSim is a Java-based framework for modeling and simulating cloud computing infrastructures and services, including data centers, virtualized hosts, containers, and federated clouds. It lets researchers evaluate cloud applications and resource allocation policies repeatably without needing real testbeds.

Use cases

• simulate cloud data center workloads before deployment
• evaluate VM placement and resource provisioning policies
• model energy-aware scheduling in cloud infrastructure
• test federated cloud scenarios in a repeatable experiment
• simulate data center network topologies for message-passing apps
• benchmark container scheduling strategies without real hardware

When to choose

• you need repeatable, scalable experiments on cloud infrastructure designs
• you want to research VM allocation or energy-aware scheduling policies
• you're doing academic work on cloud computing and need an extensible simulation framework

When to avoid

• you need to run real workloads on actual cloud infrastructure
• you want a production cloud orchestration tool rather than a simulator
• you need a non-JVM environment, since CloudSim is Java/Maven based
