Healthcare data, constituting a significant portion of global data, presents challenges due to its volume, heterogeneity, and fragmentation. Carelon, a healthcare services company, utilizes the ELK Stack to enhance real-time search capabilities on healthcare claims data, achieving remarkable performance levels with an Elasticsearch cluster. This approach allows for the integration of SQL logic into a data lake with a customized search index, facilitating the extraction and storage of insights for diverse enterprise applications. Carelon's deployment involves a sophisticated setup using Ansible for automating the configuration of ELK Stack components, ensuring compliance with stringent security standards. The deployment process, described in detail, covers infrastructure preparation, including DNS and SSL certificate setup, and highlights the use of Ansible roles and playbooks to manage the configuration of the stack across multiple compute nodes. The overarching goal is to provide scalable, secure, and efficient data search and analytics capabilities to support complex business needs within the healthcare sector.
