IST Research leverages the Elastic Stack to enhance its Pulse Platform, which aids in addressing global human security issues such as human trafficking, violent extremism, and child soldier recruitment. Initially recognized as an Elastic Cause honoree in 2017, IST Research has significantly evolved its Elastic Stack implementation, transitioning to the Elasticsearch Service on Elastic Cloud to manage cluster operations efficiently. This transition has allowed for better segmentation and specialization of clusters to meet diverse performance and scale needs, such as using Percolator for reverse querying and Pelias for reverse geocoding. The company also employs Logstash and a dedicated logging cluster for improved application insights and utilizes a multi-instance Kibana setup to provide analysts with various data visualization options. Future plans include upgrading clusters, utilizing Kibana Spaces, enhancing application monitoring with Elastic APM, and integrating Elastic App Search to refine the user search experience. These advancements allow IST Research to expand its technological capabilities and continue its humanitarian mission.
