Hello, Dojo - quick follow up from this previous post:
https://community.dataminer.services/question/daas-staas-evaluations/
Is there any supported architecture that would allow to have both on-premise and cloud-based DMAs within the same DMS cluster?
I understand DaaS//STaaS have a different DB from the Cassandra nodes used for on-premise,
but enquiring also in case of a DMA fully hosted in AWS or GCP, so without the Azure storage.
Any steer will be helpful.
Hi Alberto,
It is perfectly possible to mix on-prem and cloud-based DMAs in the same DMS cluster, BUT all DMAs in a DMS cluster must use the same storage, either a self-managed Cassandra/OpenSearch or either STaaS.
So, you can have some on-prem DMAs, some DMAs in AWS, some in GCP, some in Azure, some in OCI, etc, and add all of them in one DMS cluster. In this case, all the DMAs from all different locations will need to connect to one Cassandra/OpenSearch cluster you manage somewhere on-prem or in one of those cloud providers of your choice. Or you use STaaS and let all the DMAs connect to the STaaS location of your choice.
If you would involve a DaaS DMA into the cluster, then your options become more limited because a DaaS DMA always uses STaaS. So, in this case, all DMAs in the cluster must use same STaaS in the location you chose. And a self-managed Cassandra/OpenSearch is no longer an option in this scenario.
Let me know if something would not be 100% clear.
PS: STaaS is the preferred and recommended storage in any case. The advantages of STaaS make this a no-brainer... STaaS is just superior on any level. Security, reliability, availability, performance, robustness, ... And you can use the time you win on doing more valuable work again. Creating a database only generates maintance work for the future. Creating a cool low-code app can push your team to the next level...
