![]() ![]() General purpose storage v2 does not consume any memory from the compute node of MySQL and provides better predictable IO latencies compared to general purpose v1 storage. In a subset of Azure regions where the infrastructure is available, all newly provisioned servers land on general purpose storage v2 by default. General purpose storage v2 is based on the latest storage infrastructure which can support up to 16-TB and 20000 IOPs. General purpose storage v2 (Supports up to 16-TB storage) Alternatively, migrate to general purpose storage v2 described below that supports up to 16-TB storage if the underlying storage infrastructure is available in your preferred Azure regions shared below.Provision 10% higher IOPs than required by the database workload to account for backup IOs.Plan for compute sku tier accounting for 10-30% excess memory for storage caching and backup buffers.As a result, the memory and io consumption of storage during backups is relatively higher.Īll Azure regions supports General purpose storage v1įor General Purpose or Memory Optimized server on general purpose storage v1, we recommend you consider The backup process on general purpose storage v1 reads from the data and log files in the memory of the compute nodes and copies it to the target backup storage for retention up to 35 days. General purpose storage v1 is optimized to leverage memory from the compute nodes running MySQL engine for local caching and backups. General purpose storage v1 is based on the legacy storage technology which can support up to 4-TB storage and 6000 IOPs per server. There are two generations of general purpose storage as described below: General purpose storage v1 (Supports up to 4-TB) In General Purpose storage, the IOPS scale with the provisioned storage size in a 3:1 ratio. General purpose storage is the backend storage supporting General Purpose and Memory Optimized tier server. Basic tier is best suited for workloads that require light compute, low cost and I/O performance for development or small-scale infrequently used applications. Basic storage leverages Azure standard storage in the backend where iops provisioned are not guaranteed and latency is variable. Basic storageīasic storage is the backend storage supporting Basic pricing tier servers. Storage typeīasic storage does not provide an IOPS guarantee. The total amount of storage you provision also defines the I/O capacity available to your server.Īzure Database for MySQL – Single Server supports the following the backend storage for the servers. The storage is used for the database files, temporary files, transaction logs, and the MySQL server logs. The storage you provision is the amount of storage capacity available to your Azure Database for MySQL server. All other regions utilize Gen 5 logical CPUs that are based on Intel E5-2673 v4 (Broadwell) 2.3-GHz processors. China East 1, China North 1, US DoD Central, and US DoD East utilize Gen 4 logical CPUs that are based on Intel E5-2673 v3 (Haswell) 2.4-GHz processors. Compute generations and vCoresĬompute resources are provided as vCores, which represent the logical CPU of the underlying hardware. For more information, see the Scale resources section. You can't change the backup storage type after a server is created. You also can independently adjust the amount of storage up and the backup retention period up or down with no application downtime. Examples include servers for processing real-time data and high-performance transactional or analytical apps.Īfter you create a server, the number of vCores, hardware generation, and pricing tier (except to and from Basic) can be changed up or down within seconds. High-performance database workloads that require in-memory performance for faster transaction processing and higher concurrency. Examples include servers for hosting web and mobile apps and other enterprise applications. Most business workloads that require balanced compute and memory with scalable I/O throughput. Examples include servers used for development or testing or small-scale infrequently used applications. ![]() Workloads that require light compute and I/O performance. To choose a pricing tier, use the following table as a starting point. All resources are provisioned at the MySQL server level. The pricing tiers are differentiated by the amount of compute in vCores that can be provisioned, memory per vCore, and the storage technology used to store the data. You can create an Azure Database for MySQL server in one of three different pricing tiers: Basic, General Purpose, and Memory Optimized. ![]()
