 {{ece}} (ECE) is an Elastic self-managed solution for deploying, orchestrating, and managing {{es}} clusters at scale. It provides a centralized platform that allows organizations to run {{es}}, {{kib}}, and other {{stack}} components across multiple machines.
 
-Refer to [](./cloud-enterprise/ece-overview.md) for a detailed introduction to ECE, including its features, use cases, and architecture.

 ::::{tip}
 If you are looking for a solution to orchestrate and manage {{es}} clusters natively on Kubernetes, consider using [Elastic Cloud on Kubernetes (ECK)](./cloud-on-k8s.md) instead of ECE. ECK enables you to orchestrate Elastic Stack applications seamlessly on Kubernetes, leveraging it as the underlying platform for deployment, scaling, and lifecycle management.

+ECE evolves from the Elastic hosted Cloud SaaS offering into a standalone product. You can deploy ECE on public or private clouds, virtual machines, or your own premises.
+
+With {{ece}}, you can:
+
+* Host your regulated or sensitive data on your internal network.
+* Reuse your existing investment in on-premise infrastructure and reduce total cost.
+* Maximize the hardware utilization for the various clusters.
+* Centralize the management of multiple Elastic deployments across teams or geographies.
+
+Refer to [](./cloud-enterprise/ece-architecture.md) and [Containerized design](./cloud-enterprise/ece-containerization.md) for details about the ECE platform architecture and technologies used.
+
+## ECE features
+
+- **Automated Scaling & Orchestration**: Handles cluster provisioning, scaling, and upgrades automatically.
+- **High Availability & Resilience**: Ensures uptime through multiple Availability Zones, data replication, and automated restore and snapshot.
+- **Centralized Monitoring & Logging**: Provides insights into cluster performance, resource usage, and logs.
+- **Single Sign-On (SSO) & Role-Based Access Control (RBAC)**: Allows organizations to manage access and security policies.
+- **API & UI Management**: Offers a web interface and API to create and manage clusters easily.
+- **Air-gapped installations**: Support for off-line installations.
+- **Microservices**: All services are containerized through Docker. Refer to [](./ece-containerization.md) for more details.
+
+## ECE features
+
+* All services are containerized through Docker.
+* High Availability through multiple Availability Zones.
+* Deployment state coordination using ZooKeeper.
+* Easy access for admins through the Cloud UI and API.
+* Support for off-line installations.
+* Automated restore and snapshot.
+
+Check the [glossary](https://www.elastic.co/guide/en/elastic-stack-glossary/current/terms.html) to get familiar with the terminology for ECE as well as other Elastic products and solutions.
