An Azure relational database service.
Hi fatih uyanık •,
Welcome to Microsoft Q&A forum and thanks for using Azure Services.
As I understand, you want to use one of the Azure Databases in a multi-user desktop application.
1). In Azure, we have Azure SQL Database is a fully managed platform as a service (PaaS) database engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement. Azure SQL Database is always running on the latest stable version of the SQL Server database engine and patched OS with 99.99% availability. PaaS capabilities built into Azure SQL Database enable you to focus on the domain-specific database administration and optimization activities that are critical for your business.
Reference: https://learn.microsoft.com/en-us/azure/azure-sql/database/sql-database-paas-overview?view=azuresql
If your requirements suits, you could compare the features of Azure SQL Database and Azure SQL Managed Instance as illustrated in below link and adopt:
https://learn.microsoft.com/en-us/azure/azure-sql/database/features-comparison?view=azuresql
Another link to Plan and Manage Costs of database is here: https://learn.microsoft.com/en-us/azure/azure-sql/database/cost-management?view=azuresql
2). Next we have Azure Cosmos DB is a fully managed NoSQL and relational database for modern app development. Azure Cosmos DB offers single-digit millisecond response times, automatic and instant scalability, along with guarantee speed at any scale. Business continuity is assured with SLA-backed availability and enterprise-grade security.
You can Try Azure Cosmos DB for Free without an Azure subscription, free of charge and commitments or use the Azure Cosmos DB free tier to get an account with the first 1000 RU/s and 25 GB of storage free.
There are other databases in Azure described with usage here https://azure.microsoft.com/en-us/products/category/databases/ which can help you in choosing the right one.
Please refer to the above and let us know if you have any queries.
Hope this would help. Thank you.
