Current State
Unsupported third party images and services
• Customers deploy unsupported MariaDB images on various cloud platforms
(E.g. 99m+ MariaDB image downloads from Docker hub)
• Cloud lock-in due to incompatibility between third party implementations
• Cost surprises and lack of control for long running production applications

MariaDB - Vision and Roadmap
• Certified and supported MariaDB images
• Cloud agnostic deployment and usage
• Universal portability of applications, enable cost elasticity.

DBAAS and SkySQL Technology
● What's important to us in our framework choices:
○ Support multiple private clouds as well public clouds
○ Focus on the specifics of managing MariaDB clusters rather than building our own
automation / orchestration layer.
○ Extensible and flexible to support future requirements.
○ Open source and ability to give back to the community.
● Kubernetes checks all these boxes.
○ De-facto choice for application services.
○ The ecosystem is rapidly evolving to solve the past challenges of stateful containers.

MariaDB Containers
MariaDB provides supported container images at https://hub.docker.com/u/mariadb:
• mariadb/server
• mariadb/maxscale
• mariadb/columnstore
These containers provide the building blocks for running MariaDB as a service either as a
single container instance or multi container deployment.
As part of the offering, additional sidecar containers will be provided to provide a complete
solution, e.g. Prometheus exporters for each product.
Coming soon: certified containers in the OpenShift Catalog.

Why Kubernetes
• Kubernetes has proven wildly successful for managing containerized applications /
microservices.
• Strong industry desire and investment to support persistent state / databases has
evolved.
• Lets MariaDB focus on building the best developer / dba centric DBAAS capabilities
rather than focussing on orchestration, management and monitoring.
• Matches our strategy to:
– Help you run MariaDB where you want to: MariaDB managed public cloud, self
managed public, hybrid, and private cloud.
– Focus on end user experience rather than infrastructure centric.
– Enable machine learning based autonomous operations.

Kubernetes Features for Database Clusters
• Stateful Sets:
– Provides stable DNS and defined order of instantiation: Easier to support special
nodes as the Master.
– Persistent Volumes provide separation of storage from pod: Support failure scenarios
where a Pod may be recreated on a different Node. Smart storage or fast networked
storage can enable very high performance.
• Operator:
– An extensibility SDK that enables creation of an Application that exposes a Custom
Resource Definition (CRD) to manage the database cluster: Use code rather than
yaml & init scripts to handle complex things such as Master identification and pod
scale out.

MariaDB Operator Capabilities
• Deploy MariaDB Clusters (following our best practices):
– Master Slave
– Galera
– ColumnStore
– ...
• Scaling a cluster, e.g. add a Slave
– Auto Scale in the future
• Cluster recovery in the event of node failure
• Cluster deletion
• Cluster upgrade
• Backup and Restore

SkySQL
• MariaDB managed Database as a Service running on public clouds.
Consume as:
• Web Based GUI with end user design for easily spinning up and managing
MariaDB databases.
• Open Service Broker API to easily consume SkySQL in external tools,
platforms, or your own scripting.
• Builds on our Kubernetes Operator and knowledge in running MariaDB.
• Simple to consume and understand.

SkySQL as a Service
As we were developing the product we came to a realization that we'd benefit ourselves
from using our own platform to:
• Support better regression tests of our application platform by utilizing SkySQL to
create short lived MariaDB instances to provide a full platform stack rather than
mock our data layer.
• Provide a stable MariaDB deployment for new deployments of SkySQL to test
environments.
Our Continuous Integration testing and deployment is developed using GitHub Actions
(which is currently in beta).
To support this we have developed a SkySQL Action to enable consuming the SkySQL OSB
API to provision and deprovision MariaDB server instances to support regression tests as
well as deployments.

SkySQL Demo Scenario
To demonstrate this we'll show 3 seperate demos:
- Provisioning a MariaDB Server in the SkySQL UI to demonstrate ad-hoc / manual
creation.
- Setting up a simple GitHub Actions workflow to demonstrate the simplicity of
creating and destroying a SkySQL MariaDB instance to enable full data stack
regression tests.
- A quick look at our actual SkySQL GitHub Actions workflow that runs our test and
deploy automation.
