Planning for Access to the Cluster

Before installing a MapR cluster in the cloud, be sure to review this information so that you can plan for access to the cluster.

Public and Private IP Addresses

Cloud-based MapR clusters are installed by default in a virtual private cloud (AWS) or virtual network (Azure) using private IP addresses. You must make sure you have a way to connect to the private IP addresses of each node in the cluster. For the Azure marketplace offering and the reference templates (AWS and Azure), OpenVPN can be configured to facilitate secure access.

For the AWS marketplace offering, if you don't use a public IP address, you need to ensure that you have a way to connect to the VPC and the private IP of the nodes.

Security Groups

The MapR reference templates for AWS and Azure support the use of security groups. Security groups allow you to control precisely the traffic that can access your instance. For AWS, you can use existing security groups or create new ones. For more information, see:


Some MapR reference templates for AWS and Azure provide an option to install OpenVPN. OpenVPN is an open-source software application that creates a virtual private network (VPN) between your workstation and the cloud-based MapR cluster. If you do not want to use your network infrastructure or public IP addresses to connect to the cloud, OpenVPN can provide a secure connection. For more information, see Using OpenVPN.
