Server sizing

GlobaLeaks is designed to run on GNU/Linux. Ubuntu Xenial 16.04 LTS is the officially supported platform.

Requirements:

• CPU: Dual core 2.0GHz
• RAM: 2GB (Does not impact the maximum filesize that a platform installation can handle in upload)
• STORAGE: 20GB Allocate more based on data retention policy and (expected) traffic.
• I/O: 10Mbit/s (shared)
• Email account

GlobaLeaks makes use of email to handle submission notification. To this aim you need an email account to be used to send submission related notifications to recipients. This email account needs to be available and the respective SMTP server must support SMTPS or SMTP/TLS in order to securely manage sending of email.

For security and resource availability, GlobaLeaks needs a dedicated server. Depending on the architecture you may need one or two servers allocated to GlobaLeaks. The two-server hosting architecture requires that you use different data-centres for each of them.
