Hi @Vlad Shendykov,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
We would like to inform you that, Microsoft is retiring the single server offering and upgrading it to the Azure Database for PostgreSQL - Flexible Server. We strongly recommend that you upgrade to Azure Database for PostgreSQL - Flexible Server. Azure Database for PostgreSQL - Single Server is scheduled for retirement by March 28, 2025.
As part of this retirement, we will no longer support creating new single server instances from the Azure portal beginning November 30, 2023. However, if you need to create single server instances to meet business continuity needs, you can continue to use Azure CLI until March 2025.
Azure Database for PostgreSQL - Flexible Server is the best platform for running all your open-source PostgreSQL workloads on Azure. Azure Database for PostgreSQL - Flexible Server is economical, provides better performance across all service tiers, and provides more ways to control your costs for cheaper and faster disaster recovery. Other improvements to the flexible server include:
- Support for Postgres version 11 and newer, plus built-in security enhancements
- Better price performance with support for burstable tier compute options.
- Improved uptime by configuring hot standby on the same or a different availability zone and user-controlled maintenance windows.
- A simplified developer experience for high-performance data workloads.
