Today's companies face dozens of technologies, hundreds or even thousands of individual database instances, and petabytes of data. Explore how this complexity is changing the way we look at systems and operations.

1. The Database Trends That
Are Transforming Your
Database Infrastructure
Forever
Peter Zaitsev, Founder at Percona

2. Innovation

4. Separation of
Storage and
Compute

5. Serverless

6. Different Models
© Percona 6
Not Just Relational
Any More
Time Series Graph Data Structures

7. Multi-Model
Some Databases Support Multiple Data Models, Some even Talk Different Languages/Protocols
© Percona 7

8. Shapechangers
© Percona 8
Clickhouse can speak PostgreSQL and
MySQL Protocols
VictoriaMetrics has InfluxDB and
Graphite API
FerretDB allows to use PostgreSQL as if it
were MongoDB
Babelfish turns PostgreSQL in MS SQL
Compatible Database

9. What Is the Biggest
Factor Impacting
Open Source Now?

13. Remember…
Marten Mickos: ”Open
Source Is Not a Business
Model”

14. Hijacking GPL
• Open Source Software
Authors who did not want
others to build commercial
solution on their software
could use GPL…. Not any
more

15. Open Source
Ownership and
Governance
• Foundation Driven (Multiple
Vendors)
• Single Vendor Driven
© Percona

16. Foundation Based Open Source

CLOUD HELPS TO
ACCELERATE ADOPTION
CLOUD CHANGES WHO
CAPTURES THE VALUE

17. Single Vendor
• Tend to Be Venture Funded or
Public Companies
• Feared of Competition with
Cloud Vendors

18. Fully or Partially
Abandoning
Open Source
Licenses

19. Primary Goal of the License Change?
- Creating Monopoly on DBaaS Market

20. Why DBaaS?

STATE OF ART SIMPLICITY HIGH LEVEL OF
AUTOMATION
MAXIMIZES DEVELOPERS
FOCUS ON APPLICATION

21. What Is the
Problem with
Monopoly on
DBaaS?
© Percona
21

22. No Different
from
Proprietary
Software
Using DBaaS is a very different
skill compared to rolling your
own database setup

23. Not All Is Lost

Have We Been
Here Before?

25. Operating
Systems

26. © 2021 Percona
• Lock-in with Cloud Vendor
• Use Proprietary Solutions
• Highly Differentiated Cloud
• Hostage
• No Vendor Choice
• Freedom to Run Anywhere
• Use Open Source
• Cloud Is Commodity
• Customer
• Choice of Vendors
Open Source
Catches Up
Again

Giving Cloud Its
Originally
Intended Role of
Commodity
Infrastructure

28. So Do We Have

29. Not Yet…
But We’re Taking Our Baby
Steps

30. Kubernetes
• Kubernetes is universally
available
• Kubernetes is getting better for
stateful applications
• Kubernetes Operators are
available for most popular Open
Source Databases
© Percona
30

31. What’s Up with Kubernetes Operators?
© Percona
Day 1 and Day 2 Automation,
Toil Reduction Similar to DBaaS
UX is Different, Requires
Kubernetes Expertise
31

32. Can We Build
DBaaS on
Kubernetes?
© Percona
32

33. Many Modern
DBaaS Are Built
This Way
© Percona
33

34. Completely
Open Source
DBaaS
• Percona is building Open Source
Database as a Service in
Percona Monitoring and
Management (PMM)
• We expect to be one of Many

35. Work in
Progress…
