Availability and Replication info on Azure Document Intelligence service

Question

Hi All,

I would appreciate your help for some doubts about Azure AI Document Intelligence service.

I'm creating 2 resources in 2 different region, but the security team have to be sure that the service has high availability level and there is the way to replicate the data also in different region

1 - I don't find clear MS documentation abount the availability of the service, is the Azure Document Intelligence replicated by default in the datacenter of the zone choose in the creation phase?

2 - I also whould more information and MS documentation link abount the data replication, if I use 2 instances of document intelligence in 2 different region to best manage the workload, How should I go about finding the data even in the region of the second instance of document intelligence? maybe I have to create a storage account accessible of both region? I have to continuous replicate the data a lot of times at day if I choose to have 2 different storage account? (I don't think this is a best solution)

Hi Andrea Delfino

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

Document Intelligence is generally available in many of the 60+ Azure global infrastructure regions. 

Here are some of the key regions where the service is available:  

• North America: East US, East US 2, Central US, North Central US, South Central US, West US, West US 2, Canada Central, Canada East.
• Europe: North Europe, West Europe, UK South, UK West, France Central, France South, Germany West Central, Germany North, Switzerland North, Switzerland West.
• Asia Pacific: East Asia, Southeast Asia, Japan East, Japan West, Australia East, Australia Southeast, Central India, South India, West India.
• Middle East and Africa: UAE North, UAE Central, South Africa North, South Africa West.
• South America: Brazil South

 You can verify from Azure status . 

Azure Document Intelligence does not automatically replicate data across datacenters by default. The replication and redundancy options depend on the storage account You can use same or multiple storage for multiple document intelligence models. You can either use GRS, Geo-Zone-Redundant Storage (GZRS), Read-Access Geo-Zone-Redundant Storage (RA-GZRS) features of storage avail higher SLA as part of disaster management, you can copy the same model between multiple regions using Rest API.

Answer 2

Thank you for your very fast answer Saideep Anchuri.

Unfortunately I already read the link mentioned in your answer, I understood that if I want replicate the data I must configure the service to use storage account, so, let me to clarify my doubt:

1 - I can create the Document Intelligence service in one of the supported region and the data will be saved only in that region, but what about service availability? I mean, Microsoft replicate by default the service (not the data) in both of three datacenter of the region or the service is a single point of failure in only one datacenter of the region? (I don't think so, but I don't find any clear documentation about It)

2 - I can create the service with or without the use of storage account (right?), now, if I choose to use the storace account, the only way to replicate my datas is to enable the redundance of the storage, ok, but are, the replicated datas, always accessible in all the replicated point?
I suppose, that are only security and not available copy, so If I create 2 instances of Document Intelligence in 2 different region (in this way I'll create the GRS service replication) in order to increase the number of request or simpy degrease the throttling possibility how can use both of them as "single service" to access the datas? maybe I have to create only one storage accessible to both document intelligence instances stored in different region?

These are my doubts, thanks again for your support!
