= Executor Service

:javaFile: {javaCodeDir}/IgniteExecutorService.java

Ignite provides a distributed implementation of `java.util.concurrent.ExecutorService` that submits tasks to a cluster's server nodes for execution.
The tasks are load balanced across the cluster nodes and are guaranteed to be executed as long as there is at least one node in the cluster.

An executor service can be obtained from an instance of `Ignite`:

[source, java]
----
include::{javaFile}[tag=execute,indent=0]

You can also limit the set of nodes available for the executor service by specifying a link:distributed-computing/cluster-groups[cluster group]:
