Hi Alberto,

Let  me try to give you a bit more information on this topic.

We don't immediately have thresholds or requirements in terms of latency. And you do mention many different areas where latency plays a role...

First of all, STaaS does not use Cassandra/OpenSearch. It uses cloud native storage of Microsoft Azure. This way you basically have access to state-of-the-art storage which is super reliable, always available and always secure. Difficult, if not impossible, to achieve the same with self-managed storage.

If you use DaaS, then you can run your DaaS nodes in the same datacenter as the location you chose for your STaaS. Then latency will be minimal. But we run self-managed DMAs with up to 100 ms latency to STaaS without any noticable impact. Lower latency is of course better.

DaaS DMAs can be clustered across different continents, that is not really a problem for the syncing because each DMA operates on its own, only things like e.g. a protocol file need to be synced. Everything in the DB storage is nicely handled by STaaS.

Then you also have the latency from the DaaS DMA to the data sources or equipment. That is typically also not really a concern.

So, in general, latency is not that much of a concern for DataMiner, because we don't have storage nodes which need to be in sync like Cassandra and OpenSearch have.

Anyhow, this is definitely an interesting topic. Feel free to ping me to discuss this in more detail.
