Deployment of Elasticsearch on Nutanix Enterprise Cloud

This document is a case study detailing the deployment of Elasticsearch on Nutanix Enterprise Cloud by InterContinental Hotels Group (IHG). IHG operates two main datacenters in the U.S. and relies on Elasticsearch for real-time log analytics and operational visibility. The case study outlines the challenges faced with a previous converged infrastructure, including difficulties in scaling, high total cost of ownership, and lengthy maintenance outages. To address these issues, IHG transitioned to Nutanix Enterprise Cloud, which offered improved performance, ease of use, and cost-effectiveness. The deployment involved setting up two identical six-node Nutanix clusters and implementing best practices for Elasticsearch configuration. The document also discusses the advantages gained from the new infrastructure, such as real-time performance, simplified scaling, and enhanced infrastructure visibility. Additionally, it notes lessons learned and future considerations regarding storage and memory configurations for optimal performance.
