Using a supported high availability option doesn't provide an additional SLA. However, for database high availability within VMs, you use the high availability options like Streaming Replication that are available on a PostgreSQL database. Flexible Server provides uptime SLAs with and without zone-redundant configuration.

However, you need to pay for the provisioned VM, storage cost associated with the data, backup, monitoring data and log storage and the costs for the specific PostgreSQL license type used (if any).Īzure Database for PostgreSQL Single Server provides built-in high availability at the zonal-level (within an AZ) for any kind of node-level interruption while still maintaining the SLA guarantee for the service. In contrast, with PostgreSQL on Azure VMs you can choose and run any PostgreSQL version. These capabilities help you achieve significant cost savings, especially when you have a large number of databases. Also, Azure Database for PostgreSQL has automated backup-link capabilities. These automated actions reduce your administration costs. With Azure Database for PostgreSQL, Microsoft automatically configures, patches, and upgrades the database software. You're billed for outgoing Internet traffic at regular data transfer rates. For the latest information on the currently supported service tiers, compute sizes, and storage amounts, see pricing page You can dynamically adjust service tiers and compute sizes to match your application's varied throughput needs. All resources are billed hourly at a fixed rate. BillingĪzure Database for PostgreSQL is currently available as a service in several tiers with different prices for resources. This section describes billing and licensing basics in Azure as they apply to Azure Database for PostgreSQL and PostgreSQL on Azure VMs. This is true whether you're a startup with little cash or a team in an established company that operates under tight budget constraints. TCO is often the primary consideration that determines the best solution for hosting your databases. Single Server: Geo redundant backup and geo read-replica Customers must build this protection for themselves. Single Server, Flexible Server, and Hyperscale (Citus): All offer customers the ability to set alerts on the database operation and act upon reaching thresholds. Flexible Server: built-in with user configuration on zone-redundant storage Single Server: built-in with user configuration for local and geo Flexible Server: Not available during Preview For an on-premises solution, customers must create, manage, and maintain their own secondary data center. Azure VMs can be set up to run in different availability zones. Capabilities might include clustering, replication etc.
Customers architect, implement, test, and maintain high availability. Flexible Server – Automatic with optional customer managed window Single Server, Flexible Server, and Hyperscale (Citus) SLA The main differences between these options are listed in the following table: Attribute These tasks include maintaining and patching database servers, database recovery, and high-availability design. However, this control comes at the cost of responsibility to manage the VMs and many database administration (DBA) tasks. In the most significant difference from Azure Database for PostgreSQL, PostgreSQL on Azure VMs offers control over the database engine.
All recent versions and editions of PostgreSQL can be installed on an IaaS virtual machine. With this service, you can run PostgreSQL Server inside a fully managed virtual machine on the Azure cloud platform.
PostgreSQL on Azure VMs option falls into the industry category of IaaS.
With Azure, your PostgreSQL Server workloads can run in a hosted virtual machine infrastructure as a service (IaaS) or as a hosted platform as a service (PaaS). Azure Database for PostgreSQL - Single Server
