Prerequisities

The SlipStream server has a standard, n-tier web application architecture: the application runs within a Java web application container and stores data within an SQL database. Consequently, many administrators will be familiar with its configuration needs and modest resource requirements.

Software Requirements

The software is tested, packaged, and supported for CentOS 7 systems. The packages should install and run correctly on any RHEL 7 compatible system. The software itself should build and run on any Unix-like system, although some changes may be needed for integration with the operating system’s service management infrastructure.

Hardware Requirements

The hardware requirements of SlipStream are modest. Any modern, multicore, server-class machine should run the server without problems. At least 2 gigabytes of RAM should be dedicated to the Java Virtual Machine (JVM) running the service. Similarly 10-20 GB of disk space should be sufficient for initial use.

As with any service, the resource requirements for the server will increase with the number of users and with the number of system deployments. Use a larger machine if you expect particularly large scale or intense use of the service.

Networking Requirements

SlipStream is available through a web-proxy through the standard HTTPS (443) port. In addition, the proxy redirects all traffic on the HTTP (80) port to the HTTPS port. Consequently, firewalls on the machine or site must allow access to the HTTPS port from the users’ machines; they may also allow access to the HTTP port.

To administer and monitor the machine running the SlipStream service, you may also want to have the SSH port (22) and the Nagios NRPE port (5666) open to your administrators’ machines.

The configured SlipStream connectors act as clients of the correponding cloud service provider. Consequently, the server must also have outgoing access to the underlying cloud service endpoints. The ports used vary depending on the cloud service provider.

For any cloud service provider that does not support a virtual machine contextualization mechanism, the server requires direct SSH access (port 22) to virtual machines within those clouds.

Cloud Requirements

SlipStream is a cloud deployment engine and requires access to at least one supported cloud infrastucture. See the list of supported clouds and conditions on the associated cloud plugin to select the cloud(s) you will be making available through your SlipStream instance.
