Security
Security is an often-overlooked aspect of Elasticsearch performance tuning. Proper security configurations not only protect your data but also prevent unauthorized access that could lead to performance issues.
Implementing robust security measures includes:
- Enabling authentication and authorization: Use built-in security features like user roles and permissions.
- Encrypting communications: Use TLS to secure data in transit.
- Monitoring access logs: Regularly review logs for suspicious activities.
- Implementing IP filtering: Restrict access to trusted IP ranges.
Elasticsearch Performance Tuning
As your Elasticsearch cluster grows and your usage evolves, you might notice a decline in performance. This can stem from various factors, including changes in data volume, query complexity, and how the cluster is utilized. To maintain optimal performance, it’s crucial to set up monitoring and alerting systems that can preemptively highlight issues, allowing you to manage maintenance effectively.
