to advanced features for simulating more realistic cloud scenarios:

1. It is easier to use. [A complete and easy-to-understand simulation scenario can be built in few lines of code.](#example)
2. Multi-cloud simulations with inter-datacenter VM migrations ([#361](https://github.com/cloudsimplus/cloudsimplus/issues/361)).
3. Creation of joint power- and network-aware simulations ([#45](https://github.com/cloudsimplus/cloudsimplus/issues/45)).
4. Vertical ([#7](https://github.com/cloudsimplus/cloudsimplus/issues/7)) and Horizontal VM scaling ([#41](https://github.com/cloudsimplus/cloudsimplus/issues/41)).
5. [Highly accurate power usage computation](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/power/PowerExampleSchedulingInterval.java) ([#153](https://github.com/cloudsimplus/cloudsimplus/issues/153)).
6. [Built-in computation of CPU utilization history and energy consumption for VMs (and Hosts)](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/power/PowerExample.java) ([#168](https://github.com/cloudsimplus/cloudsimplus/issues/168)).
7. [Virtual Memory and Reduced bandwidth allocation](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/resourceusage/VirtualMemoryForRequestedRamHigherThanAvailableExample.java) when RAM and BW are oversubscribed. ([#170](https://github.com/cloudsimplus/cloudsimplus/issues/170)).
8. [Automatically power Hosts on and off according to demand](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/power/HostActivationExample.java) ([#128](https://github.com/cloudsimplus/cloudsimplus/issues/128)) and support defining a startup and shutdown delay/power consumption ([#238](https://github.com/cloudsimplus/cloudsimplus/issues/238)).
9. [Parallel execution of simulations in multi-core computers](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/ParallelSimulationsExample.java), allowing multiple simulations to be run simultaneously in an isolated way ([#38](https://github.com/cloudsimplus/cloudsimplus/issues/38)).
10. Delay creation of submitted VMs and [Cloudlets](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/dynamic/DynamicCloudletsArrival1.java), enabling simulation of dynamic arrival of tasks ([#11](https://github.com/cloudsimplus/cloudsimplus/issues/11), [#23](https://github.com/cloudsimplus/cloudsimplus/issues/23)).
11. [Allow dynamic creation of VMs and Cloudlets in runtime](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/dynamic/DynamicCreationOfVmsAndCloudletsExample.java), enabling VMs to be created on-demand ([#43](https://github.com/cloudsimplus/cloudsimplus/issues/43)).
12. [Listeners](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/listeners) to enable simulation configuration, monitoring and data collection.
13. Create [simulations](https://github.com/cloudsimplus/cloudsimplus-examples/tree/master/src/main/java/org/cloudsimplus/examples/traces/google) from [Google Cluster Data](https://github.com/google/cluster-data/blob/master/ClusterData2011_2.md)

trace files. ([#149](https://github.com/cloudsimplus/cloudsimplus/issues/149)).
14. Strongly object-oriented, allowing chained calls such as `cloudlet.getVm().getHost().getDatacenter()` without even worrying about `NullPointerException` ([#10](https://github.com/cloudsimplus/cloudsimplus/issues/10)).
15. Classes and interfaces for implementing [heuristics](http://en.wikipedia.org/wiki/Heuristic) such as [Tabu Search](http://en.wikipedia.org/wiki/Tabu_search), [Simulated Annealing](http://en.wikipedia.org/wiki/Simulated_annealing), [Ant Colony Systems](http://en.wikipedia.org/wiki/Ant_colony_optimization_algorithms) and so on ([example here](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/brokers/DatacenterBrokerHeuristicExample.java)).
16. [Implementation of the Completely Fair Scheduler](https://en.wikipedia.org/wiki/Completely_Fair_Scheduler) used in recent versions of the Linux Kernel ([example here](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/schedulers/LinuxCompletelyFairSchedulerExample.java)) ([#58](https://github.com/cloudsimplus/cloudsimplus/issues/58)).
17. [Host Fault Injection and Recovery Mechanism](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/HostFaultInjectionExample1.java) to enable injection of random failures into Hosts CPU cores and replication of failed VMs ([#81](https://github.com/cloudsimplus/cloudsimplus/issues/81)).
18. [Creation of Hosts at Simulation Runtime](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/dynamic/DynamicHostCreation.java) to enable physical expansion of Datacenter capacity ([#124](https://github.com/cloudsimplus/cloudsimplus/issues/124)).

20. TableBuilder objects that are used in all examples and enable printing simulation results in different formats such as Markdown Table, CSV or HTML.
21. Colors log messages and enables filtering the level of messages to print ([#24](https://github.com/cloudsimplus/cloudsimplus/issues/24)). ![](docs/images/log-messages-by-type.png) If you want to just see messages from warning level, call `Log.setLevel(ch.qos.logback.classic.Level.WARN);`

23. [Allows placing a group of VMs into the same Host.](https://github.com/cloudsimplus/cloudsimplus-examples/blob/master/src/main/java/org/cloudsimplus/examples/VmGroupPlacementExample1.java) ([#90](https://github.com/cloudsimplus/cloudsimplus/issues/90)).

1. Non-Live VM migration from/to public-cloud datacenters (#437).
1. Support VM startup/shutdown delay and boot overhead (#435)
1. It outperforms CloudSim 4, as can be seen [here](docs/performance.md).
