Continuum System Requirements

Overview 

Lists the server requirements for installing the Continuum application.

Client

All recent versions of:

  • Google Chrome
  • Mozilla Firefox
  • Apple Safari

Server Operating System

Officially Supported

Ubuntu Server 16.04

RHEL/CentOS 7.0 - 7.4

Non-Supported

Continuum requires 64-bit Linux OS, 2.6 kernel or higher.  Continuum supported releases are built using the "officially supported" operating systems.  Other distributions based on the officially supported operating systems should also work, but are not supported for production installations.  These include:

  • Other Ubuntu versions, or Debian distributions on which the supported Ubuntu distributions are based
  • Other RedHat, CentOS, Oracle or other distributions based on the Red Hat Compatible Kernel 

Processor, Memory and Disk Minimums

For a Proof of Concept, the minimum single-server requirements are as follows:

  • 4 Cores, 16GB RAM, 50GB free disk space (the /var filesystem should include 30GB of the 50GB of free space)

For a Production install, we recommend the following configuration:

SINGLE SERVER

  • 8 Cores, 64GB RAM, 100 GB free disk space (the /var filesystem should include 80GB of the 100GB of free space)

MULTI SERVER

Continuum:

  • 4 Cores, 32GB RAM, 100 GB free disk space (the /var filesystem should include 80GB of the 100GB of free space)

MongoDB:

  • 4 Cores, 32GB RAM, 100 GB free disk space

For more details about High Availability configurations, or other server configurations, please contact your VersionOne representative or support@versionone.com.

Database

MongoDB 3.4.x or 3.6.x

  • During a new install, the database component must be installed first before installing Continuum.
  • MongoDB 3.4 is not supported on RedHat Enterprise Linux 7.5. 

Networking

Continuum requires inbound and outbound network connectivity for interaction with third party solutions. Typically these include the continuous integration system (Jenkins, TeamCity, etc.), ALM (VersionOne, Jira), version control (GitHub, GitLab, Subversion). Most network traffic will be outbound from the Continuum server, but some may be both ways. For your specific set of tooling, consult with your Solutions Engineer.

Continuum application inbound networking on ports 8080 and 8083 though this can be easily configured to another port.

SSH access will also be required on port 22.

The Continuum Worker

In cases where Continuum is managed by VersionOne, on-premise automation and orchestration is still performed by a Continuum Worker.  System requirements for the worker is a tricky formula - highly dependent on how much automation work it will be handling.

The good news is, the Continuum Worker is easily scaled up. Simply provision more small servers or a new, beefier server, configure it as a Worker, and add it to the system.

Specifications

The minimum Continuum Worker server requirements are as follows:

  • One of the supported Server Operating Systems defined above
  • 2 Cores, 8GB RAM, 50GB free disk space (the /var filesystem should include 30GB of the 50GB of free space)

Configuration

The Worker does not require any database to be installed.  The only requirement is outbound network access to the managed Continuum instance.   Network traffic is typically light, but just like the sizing of the system, cannot be fully predicted without understanding the volume of work being done.
