Scaling multi-tenant apps with CosmosDB for PostgreSQL

Scaling your application layer is usually easy, simply spin up some extra containers, Azure Web App instances or Azure Function instances. However, your database does not scale with the same ease. In case you faced this situation, you might have chosen to store each tenant in its own database and host them in an Azure Elastic Pool. However, how do you execute cross-tenant queries, update the schema of thousands of databases, or maintain shared (non-tenant specific) data? Those and more questions will be covered in this session where you will see how easily you can build multi-tenant apps with Azure CosmosDB for PostgreSQL.

19:00 - 20:00
