Amazon RDS for MariaDB gives you full access to all the capabilities of the MariaDB open source database engine. This means that the code, applications, and tools you already use today with your existing MariaDB databases can be used with your Amazon RDS MariaDB database. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a retention period you define and enables point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your Database Instance (DB Instance) via a single API call.


Amazon RDS for MariaDB DB Instances can be provisioned with any of the three types of storage that is managed by the Amazon EBS block storage service, these are General Purpose (SSD) storage, Provisioned IOPS (SSD) storage, or magnetic storage. Provisioned IOPS (SSD) is a high performance storage option designed to deliver fast, predictable, and consistent performance for I/O intensive transactional database workloads. You can provision from 1,000 IOPS to 30,000 IOPS per DB Instance. (Maximum realized IOPS may be lower.) General Purpose (SSD) storage delivers a consistent baseline of 3 IOPS per provisioned GB and provides the ability to burst up to 3,000 IOPS. Magnetic storage (formerly known as RDS Standard storage) may be used for small database workloads where data is accessed less frequently.


In addition, Amazon RDS for MariaDB makes it easy to enhance the availability and reliability of your production workloads by automating replication across AWS availability zones. Using the Multi-AZ deployment option you can run mission critical workloads with high availability and built-in automated fail-over from your primary database to a synchronously replicated secondary database located in a separate Availability Zone (AZ), in case of a failure. Amazon RDS for MariaDB also provides a capability to create read-replicas which enables you to scale out beyond the capacity of a single database deployment for read-heavy database workloads.

Amazon RDS for MariaDB deployments are pre-configured with a set of parameters and settings appropriate for the Database Instance class you have selected, making it easy for you to launch a MariaDB Instance and connect your application within minutes, without having to do any configuration. If you would like change any configuration, that can be done through DB Parameter Groups.

Amazon RDS provides Amazon CloudWatch metrics for you DB Instance deployments at no additional charge. You can use the AWS Management Console to view key operational metrics for your DB Instance deployments, including compute/memory/storage capacity utilization, I/O activity, and DB Instance connections.

Amazon RDS provides Amazon SNS notifications via email or SMS for your DB Instance deployments. You can use the AWS Management Console or the Amazon RDS APIs to subscribe to over 40 different DB events associated with your Amazon RDS deployments.

Amazon RDS automatically applies the latest patches so you can be sure that you the MariaDB software powering your database is up-to-date. For customers who would like to manage the timing of patches directly, Amazon RDS for MariaDB also provides the ability to manually control the scheduling of patches.

Amazon RDS General Purpose (SSD) storage delivers a consistent baseline of 3 IOPS per provisioned GB and provides the ability to burst up to 3,000 IOPS. To learn more and get started with Amazon RDS General Purpose (SSD) Storage, please refer to the General Purpose (SSD) Storage section of the Amazon RDS User Guide.

You can provision up to 6TB storage and 30,000 IOPS per database instance. For a workload with 50% writes and 50% reads running on an r3.8xlarge instance, you can realize up to 20,000 IOPS for MariaDB. However, by provisioning more than this limit, you may be able to achieve lower latency and higher throughput.

To learn more and get started with Amazon RDS Provisioned IOPS, please refer to the Provisioned IOPS Storage section of the Amazon RDS User Guide.

Turned on by default, the automated backup feature of Amazon RDS enables point-in-time recovery for your DB Instance. Amazon RDS will backup your database and transaction logs and store both for a user-specified retention period. This allows you to restore your DB Instance to any second during your retention period, up to the last five minutes. Your automatic backup retention period can be configured to up to thirty five days.

DB Snapshots are user-initiated backups of your DB Instance. These full database backups will be stored by Amazon RDS until you explicitly delete them. You can create a new DB Instance from a DB Snapshot whenever you desire.

As your storage requirements grow you can provision additional storage on-the-fly with zero downtime. If you are using RDS Provisioned IOPS, you can also scale the throughput of your DB Instance by specifying the IOPS rate from 1,000 IOPS to 30,000 IOPS in 1,000 IOPS increments and storage from 100GB and 6TB.

Using the Amazon RDS APIs or a few clicks of the AWS Management Console, you can scale the compute and memory resources powering your deployment up or down. Scaling operations typically complete within a handful of minutes.

Amazon RDS Multi-AZ deployments provide enhanced availability and durability for Database (DB) Instances. When you provision a Multi-AZ DB Instance, Amazon RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ). In case of an infrastructure failure Amazon RDS performs an automatic failover to the standby, so that you can resume database operations as soon as the failover is complete. Since the endpoint for your DB Instance remains the same after a failover, your application can resume database operation without the need for manual administrative intervention.

Amazon RDS Read Replicas make it easy to elastically scale out beyond the capacity constraints of a single DB Instance for read-heavy database workloads. You can create one or more replicas of a given source DB Instance and serve high-volume application read traffic from multiple copies of your data, thereby increasing aggregate read throughput. Read replicas can also be promoted, so that they become standalone DB Instances.

Amazon RDS now allows you to encrypt your MariaDB databases using keys you manage with the AWS Key Management Service (KMS). On a database instance running with Amazon RDS encryption, data stored at rest in the underlying storage is encrypted, as are its automated backups, read replicas, and snapshots.

Using Amazon VPC, you can isolate your DB Instances in your own virtual network, and connect to your existing IT infrastructure using industry-standard encrypted IPSec VPN. To learn more about Amazon RDS in VPC, refer to the Amazon RDS User Guide. In addition, using Amazon RDS, you can configure firewall settings and control network access to your DB Instances.
