Cloud-Based Active/Passive Tungsten MySQL Clusters @ Modernizing Medicine Modernizing Medicine, a Continent customer since 2012, is a large Florida-based SaaS provider dealing with sensitive (PHI) medical data. ModMed offers electronic health records keeping, practice management, revenue cycle management, and data analytics for thousands of doctors. Watch this webinar replay with Continuent CEO Eero Teerikorpi to learn about how ModMed dealt with a lack of high availability in AWS with the help of Continuent Tungsten. AWS EC2 instances, underlying storage, and the management interface are not highly available by default. Also hear about the benefits this customer was able to reap from our solutions including continuous operations, high availability, scalability, HIPAA Compliance, and better data protection. AGENDA - Continuent Introduction - How to easily deploy MySQL Tungsten Clusters in AWS and recover from multi-zone/multi-region AWS outages - Continuent Tungsten Solutions and Benefits - Key Benefit Highlight: Continuous MySQL Operations with Data Protection - Q&A PRESENTER Eero Teerikorpi - Founder and CEO, Continuent - is a 7-time serial entrepreneur who has more than 30 years of high-tech management and enterprise software experience.

Medical SaaS Manages Sensitive PHI Data in Multi-region AWS

6. ModMed -- The Leading EHR Company
• Modernizing Medicine is the leading
Specialty-Specific Electronic Health Record
(EHR) company
• ModMed was founded 2010. It has been a
Continuent customer since 2012
• Initially a small company with less than $10M
in Funding and Revenue
• Raised total of $101M in VC Funding, and
$231M Private Equity, totaling $332M

7. Poll Question: Why Did ModMed
Choose Continuent?
As an up-and-coming SaaS back in 2012,
what do you think were the key reason(s)
that ModMed chose to work with Continuent?
• High Availability
• Data Protection
• Scalability
• Cost
• All of the Above

8. Why Did ModMed Choose Continuent?
All of the Above

10. ModMed Main Challenge
Lack of High Availability in AWS
The main challenge ModMed was facing
came from using AWS, which allowed them to
rapidly provision database and application
servers.
But the instances, underlying storage, and
management interface were not highly
available.
MySQL HA and Simple DR
Tungsten Cluster with Remote Tungsten Replica

11. ModMed Main Challenge
How was the High-Availability and
Scalability achieved?
The solution uses a Tungsten Cluster Pod
Architecture with multiple Composite Clusters
with 3-node Active Cluster (for HA) and a 1-node
Relay Replica (for DR) in each.
The Pod Architecture provides practically
infinite scalability for the SaaS providers as they
can just keep adding new Pods as their customer
base grows.
Each Pod includes a 3-node Tungsten Cluster
deployed in multi-AZ AWS, and a Tungsten DR-
node deployed in another AWS Region with all
sensitive traffic encrypted in flight (this covers
application traffic as well)

12. ModMed Challenge – Availability
What Is the Key to Success for
Availability?
Tungsten Proxy (aka Tungsten Connector) –
The Intelligent MySQL Proxy
Allows client MySQL traffic to be seamlessly
routed to another node during maintenance
operations and failovers, providing maximum
control and uptime. Manager

13. ModMed Challenge – Data Protection
How is the Data Protection
Achieved?
ModMed has SSL deployed everywhere, thus
all data is encrypted. This includes Tungsten
Cluster traffic as well as all traffic from app
servers to the database through the Tungsten
Connector.
By using SSL, as well encryption at rest (LUKS),
ModMed was able to sign a ‘BAA’ (Business
Associate Agreement) with Amazon, which
allows them to run in AWS.
Without BAA agreement, Amazon will not let
SaaS Providers run in AWS when hosting PHI
(Protected Health Information) data.

14. ModMed Challenge – Scalability
Scaling by using Pod Architecture
ModMed ‘shards’ based on number of
customers/practices using application.
This means they create a new Pod (new
Tungsten Cluster deployment) and fill it with
new practices. This until at a certain point
when they consider the Pod to be ‘full’ and
then they create yet another Pod and start the
process over again.
Each new Pod creation is automated by using
Ansible.

15. ModMed Pods – Availability, Data Protection

16. ModMed Pods –Scale with Pod Architecture

17. ModMed Challenge - Cost
Tungsten Clustering uses an annual
subscription model based on the number of
database nodes.
We do not charge per CPU count or instance
size.
Our pricing is non-linear: the price-per-node
drops significantly as the quantity of nodes
increases.

18. ModMed Challenge - Cost
True Up, No License Keys, Trust
The unique Continuent True-Up policy: during the
agreed subscription period, customer may launch
additional nodes at no extra cost.
No license key required: there is no risk of service
becoming unavailable when the subscription expires.
Everything we do is based on the honor system:
• We trust our customers
• We expect to have a long-term relationship with
our customers
• Our current average customer life-span is seven (7)
years and getting longer.

19. ModMed Solution – Tungsten Clustering
The benefits Continuent customers
achieve with our Tungsten Clustering
solution are:
High-availability, scalability, and
performance, at a very reasonable cost
level.
