Hello @krishna muppavarapu

You can find more detail regarding the ERT in Cloud endpoints in section 2.7 Connect to ERT Cloud VIP of ERT in Cloud installation and configuration guide.

Basically, the amer-3 aims for the standard single connection. The amer-1 and amer-2 aim for case that the application may establish more than one connection to independent infrastructure and subscribe to the same content simultaneously among connections.

Hi @krishna muppavarapu

Updated: I do see an issue with amers-1 endpoint. Please use amer-2.pricing.streaming.edp.thomsonreuters.com endpoint meanwhile.

Ok, I see the issue. The certificate has expired. I will raise it internally -

Hi @Gurpreet.

Thanks for your quick response. This actually raises a question on how as a consumer we should handle the primary and backup?

Service discovery gives us following endpoints (for US region).

So what is recommended strategy on selecting the endpoint url??

"us-east-1a" - amer-1.pricing.streaming.edp.thomsonreuters.com

"us-east-1b" - amer-2.pricing.streaming.edp.thomsonreuters.com

And we get one more like below

"location":[

"us-east-1a",

"us-east-1b"

],

"endpoint":"amer-3.pricing.streaming.edp.thomsonreuters.com",

Gurpreet

These both endpoints are in the same region and so your app can connect to either one.

Hi @Wasin Waeosri, Thank you for your response. I have question on how to identify the "Standard Connection" configuration. Discovery service just returns with location array with one single entry or multiple entries (both 1a and 1b) but it doesn't have any attribute for us to filter standard vs premium configuration. What is the better way to filter this response?

{

"port":443,

"location":[

"us-east-1a",

"us-east-1b"

],

"provider":"aws",

"transport":"websocket",

"endpoint":"amer-3.pricing.streaming.edp.thomsonreuters.com",

"dataFormat":[

"tr_json2"

]

},

{

"location":[

"us-east-1a"
