The document outlines the benefits and processes for migrating open source databases like PostgreSQL, MySQL, and MariaDB to Microsoft Azure, emphasizing its fully managed services, improved security, and reduced management overhead. It describes two migration options: using the Azure Database Migration Service for minimal downtime and a proof of concept approach with data dumps for testing. Successful case studies illustrate cost reductions and enhanced performance for companies after migration, reinforcing Azure's advantages over other cloud platforms.

5. PostgreSQL, MySQL and Maria DB migration to PaaS
• Focus on your App and free yourself database
management by migrating on-premises and IaaS
PostgreSQL/ MySQL/ MariaDB workloads to
Azure Database for PostgreSQL,
Azure Database for MySQL,
Azure Database for MariaDB
• Take advantage of Azure’s enterprise-ready
features on security, compliance, and intelligent
performance
• Choose the migration approach that best fits
the needs of your customer’s workloads*
• Reduce downtime on critical databases with
Azure Database Migration Service

6. Two options to migrate to Azure Opensource Databases
Option 1
Azure Database Migration Service*
Minimize downtime with continuous sync
Recommended for full database migrations
and in-production applications
Option 2
Proof of concept migration
Use dump and restore or import/export for
faster migrations
Recommended for testing and proof of
concept scenarios only
mysqldump + restore
*Azure Database Migration Service is only available on Azure Database for MySQL
Recommended approach

7. Minimize downtime using Database Migration Service
1. Migrate initial load
2. New transactions continue to replicate to target
until data catches up
3. Stop new traffic coming in (downtime started)
4. Wait for last batch of data to catch up
5. Complete DB migration
6. Update connection string (back online) DMS Continuous Sync

8. • HarvestMark migrated its existing PostgreSQL database to
Microsoft Azure Database for PostgreSQL​in just two hours
• During the migration there was no impact to their customers.
• HarvestMark saw a 20 percent decrease in cloud hosting service
costs.
• The company maintains its high standards for reliability and
speed with Azure.
HarvestMark chooses Azure
over Amazon for improved
security and performance
Customers of HarvestMark wanted them to find a new
cloud-services provider that would avoid a conflict of
interest and give them the performance and peace of
mind for their solutions

9. GeekWire is serves 2 million
readers worldwide with
Azure Database for MySQL
• Based in Seattle, Washington, GeekWire is a rapidly
growing technology news site with a global readership.
As its popularity and site traffic increased, so did
performance concerns. GeekWire decided to migrate its
WordPress site to the Microsoft Azure platform.
• This ensured better scalability and performance
• Removed pain of patching, scaling, and backing up the
database and allowed them to focus on their application
• By taking advantage of fully managed service Azure
Database for MySQL the company can scale on-demand
while cutting costs 45 percent.

10. Summary
By Migrating to Azure Open Source
Database services customers can:
• Reduce cost and database management
• Focus on Application development
• Ensure cloud scale and performance
• Take advantage of enterprise ready
features on Azure OSS Database
• Migrating to Azures Open Source
Databases
• Seamless migration with support for
latest Open Source Database editions
• Fast and secure migration with minimal
down time

14. Objection handling
Objection Response
Will I end up paying more with
managed service if I’m moving form
IaaS or on-premises?
No, you will most likely pay less. IaaS and on prem servers are traditionally over built to handle spikes in workload.
Azure Database Services for MySQL and MariaDB allow you to provision in line with your typical workloads but offer the
ability to scale-up on the fly as workloads increase. HA is built in with no need for extra replicas.
Will I need to rebuild my app?
No, Azure Database Services are built around the community database engines of MySQL and MariaDB. If your app
works outside of Azure, moving to Azure will be painless.
Will I be able to move off of Azure?
Yes, by utilizing the community versions of MySQL and MariaDB you will not be locked into the service and can leave
Azure with community tools
Why should I choose Azure for my
workloads vs. Amazon, Google, and
others?
Competitor cloud vendors not offer indemnification of intellectual property for open source workloads. Microsoft offers
the Azure IP Advantage program to protect against lawsuits.
How difficult will it be to move my app
to the cloud?
No code changes are necessary to move existing applications to Azure IaaS. Zero downtime is achievable by doing an
online migration using Azure Database Migration Services.
