Understanding High Availability (HA)
High availability refers to the ability of a system to remain operational and accessible even in the event of hardware or software failures. In Elasticsearch, achieving high availability involves distributing data and services across multiple nodes and ensuring that there are no single points of failure.
High Availability and Disaster Recovery Strategies for Elasticsearch
Elasticsearch is a powerful distributed search and analytics engine, but to ensure its reliability in production, it’s crucial to implement high availability (HA) and disaster recovery (DR) strategies. These strategies help maintain service continuity and protect data integrity in the face of failures or disasters.
This article will guide you through the key concepts, strategies, and best practices for achieving high availability and disaster recovery in Elasticsearch, with detailed examples and outputs.
