Elastic Cloud Enterprise (ECE) is an extension of Elastic Cloud, designed to address the needs of large enterprises that require centralized management of Elasticsearch and Kibana clusters while maintaining control over sensitive data. Unlike Elastic Cloud, which is hosted on AWS, ECE allows enterprises to deploy the Elastic Stack within their own data centers or private clouds, accommodating existing on-premises infrastructure investments. ECE employs a service-oriented architecture with Docker containerization to manage resources efficiently and securely, using components like Proxy, Allocator, Constructor, and Cloud UI for operations. It relies on ZooKeeper for consistent cluster-state coordination and ensures secure inter-service communication with Stunnel. This architecture provides scalability, high availability, and ease of management for enterprises, allowing them to consolidate cluster management, enforce uniform policies, and optimize hardware utilization without being tied to specific underlying infrastructure, making it adaptable to various deployment strategies.
