Our company is moving our SAP system to the cloud but for now the AE will remain onsite. My SAP agent will also be installed in the cloud and I am curious if anyone has any experience with the SAP agent in the cloud and if there are any issues with latency between the agent and the AE system.
Hi,
We are also about to install OS Agents in the Cloud and interested in hearing from anyone else who is on the same path. It would be great if we could share some information, best preactice and so on.
By the way, we do already have OS Agents placed in our DMZ zones. Those Agents will be communicating with an Automic Proxy Server in DMZ and the Proxy Server will then have an open connection to our Automic Proxy Client in our internal network.
I'm not entirely in the know where it's hosted, but for legal reasons it must be somewhere in Russia, while we're in the west of Germany. So think about 2.000km distance and a ping of about 45-50ms.
In my statistics, I see a slightly above average lag when activating actual jobs on the remote server via UC4 (albeit OS) agent, but it's still rather negligible: about 1.5s more time from job activation to job start being reported back to the server, averaged over several thousand jobs. This is just as expected and in line with other servers I have that are about half as far away, geographically.
The true issues are with firewalling (you need to ensure you're able to open the needed ports like 8871 and (again, OS agent) 2300). Plus, again speaking for the OS agent, it does not do NAT, and needs to be told the true remote IP by means of it's ini file. So if you add communication partners for the cloud host, and that cloud host is behing NAT, you need to put the IPs into the ini file and restart the agent each time, which is anoying.
I'm not sure how the SAP agent behaves with that, it was configured before my time and since it probably only talks to a central SAP server on-site, it's probably less of a maintainance nightmare.
Hth,
Carsten
