Create and Manage Cloud Clusters with MathWorks Cloud Center
1-13
Server Sockets Accessed by Client
MATLAB Distributed Computing Serverâ„¢ and the Cloud Center require the client to
contact servers listening on certain sockets within the cloud. If you limit access to remote
ports from your client machines, you should be sure to allow access to the following
remote ports for communication with the cluster resources:
TCP Ports Usage
443 Web access to Cloud Center
22 SSH
27355 Access to MATLAB job scheduler on head node
14350–14415 MATLAB pool or parallel pool workers
In addition, all ports are open for communication between machines within the same
cloud cluster, as defined by rules in your AWS security group.
Security Within Clusters
Users with access to a cluster can perform all supported cluster activity. More
specifically, anyone with access to the cluster can see or manipulate all the files,
processes, and jobs in the cluster, regardless of ownership. If security is a concern,
consider limiting who has access to shared clusters or providing users with their own
clusters.
