High performance
The system depends on high-quality Linux servers that conform to or exceed the recommended system specifications given by RDX works.
High uptime
A second Linux server is always prepared to assume the responsibilities of the primary node should it encounter any issues. Additionally, by employing Ansible, my deployment process has been automated. This ensures that recovery by creating a new node would be very quick in case both nodes do fail.
Monitoring
In addition to using Grafana for monitoring the node's performance and uptime, I created this 3,5 inch Raspberry Pi powered monitoring dashboard which will be active 24/7 on my desk. The code is open-source and I will be adding more features to it like alerts and more cool metrics.
Decentralization
Too much XRD has been staked to nodes that run in American datacenters (22%). This node will be running in the beautiful Dutch city of Alblasserdam, while the backup node will be running in Germany.
Security
To ensure the security of the network and make sure that stakers get their staking rewards, I have configured the validator to be resilient against attacks by employing technologies such as firewalls, 2FA and DDoS protection.
