Continuent
“The MySQL Availability Company”

Where Does Continuent Fit In?
Continuent has witnessed the rise of Open
Source and Cloud Computing since 2004.
We have been at the forefront of the market
need for platform-agnostic, highly-available,
globally-scaling, clustered MySQL databases
that are driving businesses to the cloud today.
Continuent is not the biggest. Never.
We are the best at what we do. Always!

Goals for the High Noon Webinar Series
Explore and compare how to deploy Geo-Scale MySQL using various MySQL
Solutions:
• Local rapid-failover, automated high availability
• Geographically distributed, low-latency data with a single consolidated view
• Fast local response times for read traffic
• Ability to deploy MySQL primaries in multiple regions
• No changes to application code
• Complex schema changes while keeping applications available
• Avoid provider lock-in
MySQL is understood in a broad context, including MySQL, MariaDB and Percona Server.
Also AWS RDS MySQL, AWS RDS Aurora, Azure MySQL, and Google Cloud SQL are applicable in some context.

AWS Aurora Key Characteristics
• MySQL 5.6/5.7 Compatible (not native-MySQL, nor MySQL 8.0 features, nor MariaDB 10.x features)
• Read Replicas
• Distributed file system
• Cross-Region asynchronous replication within AWS
• Promote remote read replica to standalone DB cluster
• Fast, in specific scenarios
• Very basic RDS proxy available for additional charge
• “Serverless” version available

AWS Aurora Cross Region Requirements
• Source Aurora cluster
• Enable binary logging on the on the source Aurora cluster (quite a few settings to change)
• A VPC in the target cluster
• Database Subnet within the VPC (be sure you’re familiar with VPC’s and subnets, a lot of issues are
caused here)
• Subnet should be public-accessible if machines outside of the network will access the Aurora
instance!

RDS Proxy
• New, introduced in June, 2020
• Reduces failover times up to 66%, preserves application connections
• Integrates with AWS IAM manager
• Supports connection pooling and can reuse connections
• No read/write splitting
• Per above, does not work with Aurora Global Database
• Does not work with Aurora Serverless
• Must reside is same VPC as Aurora Cluster

Limitations Using AWS Aurora
• Primary is single region only
• Failover disconnects application
• Long failover times ( > 30 seconds)
• InnoDB engine only
• Application must be read/write aware, even when using RDS Proxy
• All data stays in AWS
• Database maintenance and schema changes will cause application outages
• Proprietary and not open source
