MariaDB can be deployed on Microsoft Azure in several configurations: - As a standalone MariaDB server virtual machine for basic use cases. - As a MariaDB Galera cluster with MaxScale for high availability and scaling across multiple nodes. - As a preconfigured MariaDB enterprise cluster and MaxScale solution that can be deployed in about 15 minutes for production use. - Through the Azure Marketplace or programmatically from the command line. - Common configurations provide options for storage, compute resources, networking, and accessibility.

6. MariaDB Server Standalone
• Single MariaDB server instance
• Deploy in about 5 minutes
• Deploy from the Azure Marketplace
• Deploy programmatically from the command line
• Start with this VM, adjust it to suit your needs
• Start additional VMs, create replication or clustering topologies

7. MariaDB Server Standalone
• MariaDB root auth via unix_socket plugin
• Add data disks
– mariadb_migrate_datadir script
– Use LVM to mirror volumes, etc.
• MariaDB Repository configured in image
• Will be updated to 10.2 when it's GA

8. MariaDB High Availability & Scaling
MariaDB provides
Galera ClusterReplication
• Synchronous replication semantics
• Active-active multi-master topology
• Read and write to any cluster node
• Automatic membership control, failed
nodes drop from the cluster
• Automatic node joining
• True parallel replication, on row level
• Direct client connections
• Global Transaction ID (GTID)
• Multi-Source Replication
• Schema-agnostic parallel replication using
MariaDB group commit

9. MariaDB MaxScale
MariaDB MaxScale is a next-generation database proxy that manages security,
scalability and high availability in a scale out deployment.
High Availability
Ensure uptime
with no single
point of failure
and minimize
downtime
during upgrade
Data Streaming
Stream transactional
data to data lake for
real-time analytics
Scalability
Manage your
scaled-out
infrastructure
without changing
application code
Security
Secure database
firewall to prevent
cyber attacks like SQL
injection and DDoS

10. MariaDB MaxScale
Content Aware
▪ Aware of the content of the request
▪ Aware of the configuration and state of the server
Query Routing
▪ Load balancing: Monitor and balance transaction load
▪ Automatic Read/Write splitting
Replication
▪ Replicate data from master to large number of slaves
Multi-tenant Database Scaling
▪ Schema sharding
Read
Write
Manage your High Availability and Scale Out environments
