SAP analytic cloud network performance

[former_member724002]

Hello,

I'm wondering if there's any way to make sure I have a consistent network bandwidth when using SAC connected to my HANA database systems in Azure.

In terms of connection, I'll be using a Live Data connections with CORS type, as we want our data to stay in our hana database 2.0 hosted in Azure ( so almost as if it was on-prem from a SAC perspective ) . There won't be any data replication from our hana database to SAC.

In this configuration , 2 types of traffic are involved : The data traffic which will go straight from the user's web client to the hana database ( and for this I know I have a consistent network bandwidth as this will go through our express route ) , and the metadata and optionnaly SAML assertion traffic that will go through the internet. This is depicted in the following SAP diagram :

From my point of view, I can't guarantee any level of performance for the metadata / SAML assertions traffic as this goes through the internet. I'm wondering if there's a way to have this traffic go through some kind of dedicated link ( like some equivalent of express route but from SAP ) from SAP DCs where SAC is hosted , to my network ?

That way I could be sure I have a consistent network performance for both the data and metadata traffic.

If such a possibility does not exist, what would be the impact , in terms of performance, of having a slow connection on the metadata traffic ?

Best regards,

Jhon.

Hello Jhon,

Meta data exchange is not as heavy as data exchange between client browser and HANA DB (in scenario). Meta data usually consist of model structure and index's for Smart insight (even for Live HANA connection). Data exchanges so small that even a 500KBps speed would be sufficient. Beside the exchange is not as frequent. Even with below average company level internet connection would guarantee consistent performance.

On a side note -AWS allows you create tunnel with predefined band width, this is to make sure you get consistent transfer of data between your on-prem to AWS server. Though this depends upon you company side WAN connection. A patchy connection will impact impacts this too.

I don't think such dedicate setup available for SAC.
Other option is to use tunnel connection, though direct live connection via CORS have better performance compared to reverse proxy or tunnel.

Private cloud based SAC is not an options as all your connection are live HANA connection. So HANA DB and resource performance on SAC side doesnot matter.

Hope this helps.
