Host Access for the Cloud


Host Access for Cloud Specs

Deployment options:

Virtual Software Appliance

The first option is an appliance, a virtual machine that contains everything you need to run Host Access for the Cloud in a virtualization environment, with minimal effort.

Linux installer to support your Linux Distribution

The second option is a Linux installer where you choose and manage your own Linux distribution, when that is a priority.

System Requirements:

Each virtual appliance VM or Linux install requires:

Minimum CPU, memory and storage requirements:
8 CPU Cores
60 GB virtual disk space (SSD)

Note: These are the minimum resources required for each node. These requirements assume that no other production software is installed on the node.

Fast Storage:

The use of a solid-state drive (SSD) or other fast storage solution is required.

Fixed IP address:

A fixed, non-changing IP address is required for each node. DHCP (Dynamic Host Configuration Protocol) is supported but the IP must be reserved and cannot change.
