Supported Environments

A Hub service does not have a specific set of hardware requirements. These requirements vary based on the size of your database and the average number of transactions that are processed on a regular basis.

Our own Hub installation runs in an Amazon EC2 environment on an M3 General Purpose Extra Large instance. To run the service, we allocate 9 GB to the Java heap. Our Hub installation manages more than:

• 646,000 user accounts

• 527 groups

• 421 projects

• 75 connected services

You can use this information for comparison to determine how much storage, processing power, and memory you need to run your installation.

Compatibility with ARM Processors

Hub is currently incompatible with systems or devices that use the ARM64 processor architecture.

Hub is a web application that requires Java support. A compatible version of the JRE is bundled with the installation package, which means you don't need to install Java separately on the server that hosts the application.

You also do not need to install Java on client machines that access the application through the web interface.

We do our best to ensure the stability of Hub installations on platforms that are commonly used for public servers on the internet. However, we cannot guarantee that the application is compatible with all possible environments.

Hub is supported on 64-bit versions of Windows and macOS as well as most popular distributions of Linux and other *nix environments. We regularly test and deploy on Fedora (Red Hat), Ubuntu, and Debian, but our Docker container installation should work with any Linux distribution.

We do not support installations on versions of operating systems that have reached the end of their support lifecycle.

Hub runs in a standard web browser. With the speed at which browsers are updated, it is not always possible to pre-certify every browser. We resolve functional issues in new releases of supported browsers as they arise.

We encourage you to update your browser to the latest version. You benefit from the latest security and stability fixes.

Hub is supported in the two latest stable versions of the following web browsers.

• Chrome

• Firefox

• Safari

• Edge

• Opera

From version 2019.1, Hub no longer supports Internet Explorer.
