Microsoft Azure Open Source Databases

MariaDB, MySQL, and PostgreSQL on Azure

  • Microsoft Azure Offers 3 different open source Database Platform on Azure (MySQL, MariaDB, PostgreSQL) and this 3 Database platform service comes with native high availability, automatic patching, automatic backups, and the highest level of security protection
  • Service Tiers Supported by open source Database Platform on Azure
  • Basic: Best of a light workload
  • GP (General Purpose): Best for High Workload required high IO
  • Memory-Optimized: Best for High Workload required high performance and in-memory speed.
  • Supported version for open Source database platform on Azure
  • MySQL and MariaDB on Azure Transactions on either platform are written synchronously to storage. If a node interruption occurs, the database server will automatically create a new node and subsequently attach the storage to the new node. Any transactions in flight are not committed and active connections to the database are dropped. As mentioned with Azure SQL Database, it is important to ensure that applications that connect to the database service include retry logic, also known as connection resiliency, in their database connections.
  • Database migration can be done for 3 open source database platform using Microsoft DMS Azure Database Migration Service
  • Azure SQL Database for MySQL and PostgreSQL does not have a TDE: But Microsoft provided a disk encryption method.
  • Azure PostgreSQL Deployment Model (Single Server, Flexible Server {Preview} or Hyperscale {Citus})
  • Flexible Server, a new deployment option now in preview for Azure Database for PostgreSQL and Azure Database for MySQL, offers customers enhanced choice, performance, and scale by building on a new architecture with native Linux integration “Ignite 2020 News”
  • Azure PostgreSQL Hyperscale used for large-scale databases that scale-out across multiple nodes
  • Azure PostgreSQL Hyperscale Server Called Nodes and it is working together in a shared-nothing
  • And the nodes are added to the Server Group
  • Each Server group have something called a coordinator node and multiple workers nodes
  • When the APP Sends the Transaction to Azure PostgreSQL Hyperscale, it sends it to the coordinator node and the coordinator node will find the worker nodes to collect the data to the APP.
  • Azure PostgreSQL Hyperscale is sharded, this means the data in a table can be split into multiple nodes using a type of table called a distributed table.
  • During the Deployment of Azure PostgreSQL Hyperscale Microsoft allow you to create additional worker nodes along with a coordinator node
  • You can deploy Up to 20 worker nodes and in case if you need more you should communicate with the Microsoft support team
  • You can connect to Azure PostgreSQL Using SQL or pgAdmin Clint
  • More information Check Documentation: https://docs.microsoft.com/en-us/azure/postgresql/
  • Query Store Supported in Azure MySQL https://docs.microsoft.com/en-us/azure/mysql/concepts-query-store

SQL Server table partitioning – planning and implementation guidelines


Nowadays, the big environments that have large databases with a heavy amount of transaction they had one common performance issue in the OLTP transaction when the database size increased to the hundreds of gigabytes or more it will be difficult to load data.

Microsoft SQL Server provides us table partitioning to make this OLTP operation more either and manageable. Applying the partitioning on the large table it will split the table and its indexes into the smaller partition, at this time the maintenance procedure can be applied to an exact partition instead of doing it on the whole table. Additionally, the SQL Server engine will direct the filtered queries to the suitable partitions instead of the entire table. All of this will enhance the performance of OLTP transactions significantly. I will list Commons steps for database migration, including the following:

  • Concept of table partitioning
  • Why we need to implement Table Partitioning
  • Table partitioning limitation and restriction
  • Table partitioning type
  • Table partitioning dependence
  • Table partitioning implementation
  • Conclusion
  • Useful links

Azure Single Database Fundamental


AS we now Azure SQL Single database is one from deployment Azure Database models if you need to know more information check this post-Azure Database Deployment model options today I am writing about Fundamental information for Azure Single Database

For More Azure Database Articles Check this Link and If you are Preparing for AZ-103 Azure Administrator Certification check this Article

Create Azure Single Database
  1. The Single Database deployment option creates a single isolated database in Azure SQL Database
  2. Azure Single Database Support DTU-based and Vcore-based Purchased Model
  3. The internal of SQL Database server is hidden from the end-user and all are managed by Microsoft Azure
  4. Azure Single Database has it is own Resources (DTU or V-Core) and this resource will not be shared with other databases in the same single instance. Each Database has dedicated resources.
  5. Single Database Isolated meaning if you created two single databases on the same single database server each Database has dedicated resources and the two databases cannot be communicated together and I think this one is a security feature
  6. This means Azure Single Database is the best option for small workloads with applications connects to one DB.
  7. To Provision Azure SQL Single Database, you need (resource Group, Database name, Server Name, User Name, Password, Location, deployment option either single or elastic pool, Compute Storage and purchase model either DTU-based or vCore-based)
  8. In Azure SQL Single database provisioning you can create new or select existing one from (Resource group and Server name)
  9. In Azure SQL Single database provisioning the (resource Group, Database name, Server Name) Should be a unique name.
