+## RDP and ERT in Cloud
+
+You may consider the strategic [Refinitiv Data Platform (RDP)](https://developers.refinitiv.com/refinitiv-data-platform) web base APIs platform. RDP APIs give you seamless and holistic access to all of Refinitiv content (whether real-time or non- real-time, analytics or alternative datasets) such as Historical Pricing, Environmental Social and Governance (ESG), News, Research, etc and commingled with your own content, enriching, integrating and distributing the data through a single interface, delivered wherever you need it via the following delivery mechanisms:
+* Request - Response: RESTful web service (HTTP GET, POST, PUT or DELETE) 
+* Alert: delivery is a mechanism to receive asynchronous updates (alerts) to a subscription. 
+* Bulks:  deliver substantial payloads, like the end of day pricing data for the whole venue. 
+* Streaming: deliver real-time delivery of messages.
+
+Please see [RDP API Overview page](https://developers.refinitiv.com/refinitiv-data-platform/refinitiv-data-platform-apis) for more detail.
+
+As part of RDP, [Elektron Real Time in Cloud (ERT in Cloud)](https://developers.thomsonreuters.com/elektron/websocket-api/quick-start?content=45253&type=quick_start) gives you access to best in class Real Time market data delivered in the cloud.  ERT in Cloud is a new delivery mechanism for RDP, using the AWS (Amazon Web Services) cloud. Once a connection to RDP is established using ERT in Cloud, data can be retrieved using [Elektron WebSocket API](https://developers.thomsonreuters.com/websocket-api) (the same as TRKD Streaming Service).
+
+Key benefit of the strategic RDP and ERT in Cloud platform are the Cloud Delivery. The Platform is based on [Amazon AWS](https://aws.amazon.com/), the world class leading Cloud Provider for developers. The RDP and ERT in Cloud support output for multiple cloud vendors such as AWS, Azure, GCS, etc. for cloud-native or on-premise integration. The ERT in Cloud servers are hosted in multiple location world-wide which lets the application choose the closest server based on their region for full potential. 
+
+Please refer to [Elektron WebSocket API Quick Start - Connecting to Elektron Real Time in Cloud](https://developers.refinitiv.com/elektron/websocket-api/quick-start?content=45253&type=quick_start) page and [How to migrate the WebSocket application from TRKD Streaming service to Elektron Real Time in Cloud](https://developers.refinitiv.com/article/how-migrate-websocket-application-trkd-streaming-service-elektron-real-time-cloud) article for more detail.
