We're shortly to embark on Migrating a client's Ayaya IP Office in Azure as part of an Azure migration project, the Avaya instance is a relatively young procurement hence needs to be retained.
Below is the recommended Avaya configuration and is something we're in the process of implementing with great care and attention.
We're very interested in the performance levels and survivability we can create whilst running the service in Azure.
The client's SIPs still come in through on-premise session border controllers so this is essentially a lift and shift to prolong the life of this service.
Will report back here as we work through more.
