OpenSearch versus Big Data Consulting by Experts - BigData Boutique
Compare	OpenSearch	Big Data Consulting by Experts - BigData Boutique
Verdict	Depends	Depends
Best for	High-volume log analytics	Production Elasticsearch/OpenSearch teams
Who it's not for	Small apps needing simple site search . badly overkill	Small teams with a single database
Privacy	Active open-source project with published CVEs and a clear disclosure process; recurring Log4j scanner flags and a recent DoS and SSRF issue, both patched.¹¹	No known public vulnerabilities found in the sources reviewed.¹³
Support quality	No support evidence in sources	24/7 support; first accredited OpenSearch provider
Public sentiment	Users praise its scale and ease of use but frequently complain about managed-hosting costs and polish versus Elasticsearch.^¹	No independent user reviews were found; third-party mentions are directory listings and one vendor-published AWS case study.
Biggest gotcha	AWS Serverless bills a 2-OCU minimum around the clock; small workloads report ~$350+/month^⁶	No public rates; open-ended platform consulting can balloon past budget without tight scope¹³
