Elasticsearch and OpenSearch are powerful enterprise search and analytics engines that have become popular in the world of data management and telemetry analysis due to their ability to swiftly search, analyze, and visualize data. However, users must carefully consider the cost implications of using these tools, as proprietary licenses can lead to vendor lock-in and high licensing costs. Additionally, managing Elasticsearch and OpenSearch can be complex, requiring multiple teams to allocate budget and personnel to maintain stability and scalability. Both systems also face challenges with long-term storage and retention, including slow indexing, query performance degradation, and sub-optimal sharding strategies, which can impact data analysis effectiveness. Mitigating these challenges may require replacing these tools with modern, serverless alternatives like ChaosSearch, which offers unlimited scalability, industry-leading resiliency, and massive time and cost savings for high-volume log and metric telemetry analytics workloads that demand longer data retention.
