Private Cloud Monitoring

Maximized system uptime and performance

The eLABJournal Private Cloud is a managed hosting solution that not only includes system hosting. To maximize system uptime and performance, Bio-ITech continuously monitors the health and application uptime of an eLABJournal Private Cloud installation using Zabbix. In case the server or application is unavailable or irregularities on the server or network are detected, our system engineers are notified automatically to solve the issue and to avoid escalation. Any event on the server is automatically logged.

eLABJournal Private Cloud High Availability (HA)


Although with our monitoring policies we maximize system uptime, downtime related to technical issues in the Amazon AWS Cloud infrastructure are beyond our control. To mitigate those risks, the eLABJournal Private Cloud is also available as an High Availability (HA) installation. With the eLABJournal Private Cloud HA, a duplicate system installation is available in a different physical AWS Cloud environment. <!– Read more about the eLABJournal Private Cloud HA. –>
