 # TCP healthcheck and restart for unmanaged GCE instances
 
-This example shows how to leverage [Serverless VPC Access](https://cloud.google.com/vpc/docs/configure-serverless-vpc-access) and Cloud Functions to organize a highly performant TCP healtheck for unmanaged GCE instances. Healthchecker Cloud Function uses [goroutines](https://gobyexample.com/goroutines) to achieve parallel healthchecking for multiple instances and handles up to 1 thousand VMs checked in less than a second execution time.

 **_NOTE:_** [Managed Instance Groups](https://cloud.google.com/compute/docs/instance-groups/autohealing-instances-in-migs) has autohealing functionality out of the box, current example is more applicable for standalone VMs or VMs in an unmanaged instance group.

 - `TCP_PORT` port used for health checking
 - `TIMEOUT` the timeout time of a TCP probe.
