Business-Critical MySQL using open source is free, right? Managed MySQL cloud services don’t need DBAs, right? Think again! MySQL can be the perfect answer for fast-growing, highly-performant and geographically-distributed database environments, but in order to function as a business-critical system with immediate response times, the ubiquitous database server needs a little help. Watch this special webinar to learn about the limitations and hidden costs of DIY solutions for business-critical MySQL. In addition, find out why ‘managed’ database-as-a-service solutions, like AWS Aurora, may not be quite as self-managing as people would like to believe. You’ll hear several case studies on how clients are effectively utilizing Continuent Tungsten software and Datavail services to optimize their MySQL environments.

8. Poll Question #1
What version of MySQL are you currently working with?
• Oracle MySQL (OSS and/or Enterprise)
• MariaDB
• Percona Server
• Amazon RDS MySQL and/or Amazon Aurora
• None, I'm here to inform myself

9. MySQL continues to be leader in database
market
• Gartner doesn’t include “open source” database platforms in their analysis of market share because it is
based on revenue.
• Datanyze ranks MySQL #1 based on domains with 85,575 domains and 33.04% market share
– More than twice second place Microsoft SQL Server with 34,335 domains and 13.26% market share
– https://www.datanyze.com/market-share/databases
• Stack Overflow ranks MySQL as most popular database among developers with 44.3% approval rating,
followed by Microsoft SQL Server in second with 30.8% ranking
• DB-Engines ranks MySQL second among database platforms in market share AND the fastest growing
– As of Sept 2019, MySQL holds second-place ranking behind Oracle and just ahead of Microsoft SQL Server
– DB-Engines score model is a function of mentions/questions/interest, etc.

Ranking by “market share” is an inaccurate measurement since it’s most often based on revenue. Different
criteria is used to determine “market share” of open source platforms.

12. Hidden costs of ‘free’ DIY solutions for
business-critical MySQL
DIY -- Do It Yourself
Decide the architecture and select the individual
solutions to handle each layer of the topology. Each
part must be installed, configured, maintained and
monitored separately.
DIY requires a significant in-house investment of
time, money and human resources to build a full,
tested solution, and even then would not be as
mature, stable or well-documented as a Complete
Solution offering.
DIY requires that your DBAs do a lot of manual
work. Properly automating local failover is an
enormous task, especially when trying to avoid split-
brain situations and various edge cases.
Complete Solution
Tungsten Clustering, which consists of three core
components (Manager, Connector and Replicator),
handle all of the messaging and control in a
seamlessly-orchestrated fashion.
Tungsten Clustering has more than 100 person-years
of development maturity.
Tungsten Clustering is a complete, proven and
supported solution with significant resources
including extensive documentation, release notes,
white papers, instructional training videos and
webinars.

13. Hidden costs of ‘free’ DIY solutions for
business-critical MySQL
DIY -- Do It Yourself
With DIY, scripting a cohesive solution for geo-distributed,
active-active, highly-available MySQL is definitely a
non-trivial task.
Standalone, "free" MySQL proxies must be painstakingly
configured to have visibility into the DIY cluster and do not
automatically gather the configuration from the other selected
cluster components.
With DIY, recovering failures is time-consuming, manual
and laborious.
With DIY, almost all updates and upgrades (MySQL version,
schema changes, etc.) will require down-time.
For a DIY solution, there is no single place to go for support.
Many of the tools provide only online peer-based support, or
require support contracts from multiple vendors.
Complete Solution
Tungsten Clustering provides geo-scale active/passive and
active/active clusters right out of the box with in-flight
encryption by default.
Tungsten Connector is intelligent proxy and can route the traffic
and load-balance globally.
Tungsten Clustering handles all failover and recovery operations
automatically in sub-second for local HA, and automated for
global DR.
Tungsten Clustering allows continuous, zero-downtime
maintenance operations.
The entire solution is supported by the same team end-to-end.
For urgent support cases, our average response time is less
than three (3) minutes!

14. How managed are the ‘managed’
database-as-service solutions?
• Major Version upgrades are not self-managed
• Optimal Configuration
• Data Consolidation
• New Features and Functionality
• Deployments and Schema Changes
• Multiple Storage Engine Support
• Conflict Resolution
• Security Considerations

15. Poll Question #3
How do you currently manage your MySQL environment?
• Internal DBAs — We manage it ourselves with the help of OSS tools
• Internal DBA and Remote DBA service — We use a combination of DIY solutions and
outside consulting
• Remote DBA service — We have completely outsourced database management
• DBaaS and Commercial Solutions — We use database as a service and commercial
solutions to help us manage

16. Use Case: MySQL HA with Read Scale
Continuous MySQL Availability with Scaling
[Single Tungsten Clustering topology – 3-node Active Cluster with
Additional Read-only Slaves]
Challenge
Web-based applications are inherently 24/7/365 operations, thus they require zero
downtime, even during maintenance operations. Also, as the user base grows, web-
application providers need to have an easy and consistent model to scale.
Solution
The core Tungsten Clustering MySQL high-availability topology is an ideal architecture
for providing practically unlimited read scaling.
Benefits
Availability, Scalability
and Performance
Customer
Online Radio, which scaled from millions of listeners
to tens of millions using Tungsten Clustering
VPC

17. Use Case: MySQL HA/DR for SaaS
MySQL High Availability and Disaster Recovery
[Composite Active/Passive Tungsten Clustering topology – Pod Architecture with multiple 3-node Active
Clusters (for HA) and 3-node Passive Clusters (for DR)]
Challenge
Using AWS allowed Customer to rapidly provision database and application servers. However, the
instances, underlying storage, and management interface were not highly available. By using Tungsten
Clustering, Customer can quickly deploy clusters in AWS and recover from multi-zone AWS outages.
Solution
Customer’s current, growing deployment includes 17 Tungsten MySQL clusters in AWS (totaling 68
MySQL servers) using a Pod Architecture. Each Pod includes a 3-node Tungsten Cluster deployed in
multi-AZ AWS, and a DR cluster deployed in another AWS region with all replication traffic encrypted in-
flight.
Benefits
Availability, Scalability,
Data Protection
Customer
SaaS provider with sensitive medical data, which offers EMA, the
Electronical Media Assistant solution (that ‘speaks the language of doctors’).

18. Use Case: Geo-Scale MySQL for Global Operations
Multi-Cloud MySQL
[Composite Active/Passive Tungsten Clustering topology – One Active Cluster and
Multiple Passive Clusters in four (4) AWS Cloud Regions]
Challenge
Servicing a single application for the geographically-distributed audience is a unique
challenge. It requires fast local response times for read traffic, a limited number of
updates, and a single consolidated view of the data across the world. This is very
typical for gaming applications, and for all account/subscription management systems.
Solution
Geo-distributed Composite Tungsten clusters (one active and three passive MySQL
clusters) in USA West (Active), USA East (Passive), EMEA (Passive) and APAC (Passive).
Benefits
Geo-scale, Availability,
Disaster Recovery
Customer
A global gaming company with more than 350 million
world-wide player accounts, and several hundred million
player accounts combined.
