📄️ Alerting & Incident Response
Alerting should be very specific. It’s easy to just set thresholds to every possible monitored metric and add alarm to it.
📄️ Client Diversity
Client diversity is a critical aspect of maintaining a robust and secure Ethereum network. One risk that a node operator faces is a critical bug in a node. Even though some aspects of it could be mitigated via a good upgrade process (see "Upgrading Nodes"), Ethereum has multiple nodes, both CL (Consensus Layer) and EL (Execution Layer), that are produced by different vendors, using different technologies (see also Nodes). This diversity helps in reducing the risk of a single point of failure.
📄️ Geographical Distribution
Geographical distribution of validator nodes is a crucial aspect of maintaining a resilient and secure blockchain network. By spreading nodes across different regions, the network can better withstand local disruptions, such as natural disasters or regional internet outages, ensuring continuous operation.
📄️ Monitoring
Monitoring is what metrics to keep track of when running validators.
📄️ Redundancy & Failover
In web2 world, whenever one wants to make things highly available, they usualy run a redundant setup.
📄️ Resource Scaling
Efficient resource scaling is essential for maintaining the performance and reliability of validator nodes. This guide provides insights into managing various resources effectively.
📄️ Server Migration
Migrating validator nodes to a new server or infrastructure can be a complex process, but with careful planning and execution, it can be done smoothly. Here are some key considerations and steps to ensure a successful migration:
📄️ Distributed Key Management
Distributed Key Management (DKM) is a critical component in ensuring the security and reliability of validator operations. By distributing key management across multiple nodes or entities, the risk of a single point of failure is minimized, enhancing the overall security posture.
