DBaaS is the fastest growing way to deploy databases. It is fast and convenient and it helps to reduce toil a lot, yet it is typically done using proprietary software and tightly coupled to the cloud vendor. We believe Kubernetes finally allows us to build fully OpenSource DBaaS Solution capable to be deployed anywhere Kubernetes runs – on the Public Cloud or in your private data center. In this presentation, we will describe the most important user requirements and typical problems you would encounter building DBaaS Solution and explain how you can solve them using Kubernetes Operator framework.

1. Path to Open Source
DBaaS with Kubernetes
Keeping your data portable

2. Early Days of
Modern Open
Source

3. Installation of
Open Source
Software
© 2020 Percona 3
Download Sources, Patch and Compile
Tar.gz binaries and INSTALL
Packages with Dependencies - .deb .rpm
Package repositories APT and YUM
Docker, Snap etc

4. Trend
© 2020 Percona 4
MAKING IT EASY REDUCING BARRIER TO
ENTRY

5. Modern Open
Source
Most Developers will not be
able to build from scratch all
tools they use
© 2020 Percona 5

6. Not a bad
Thing…
© 2020 Percona 6
Allows us to use more complicated,
more valuable software
More people can be Open Source
Developers

7. The Dark Side

8. Next
Simplification
comes with
Vendor Lock-In in
the Cloud
© 2020 Percona8

9. Current State
Easiest/fastest way to deploy
Open Source (and Compatible)
Software is to do it in the cloud,
using Proprietary API

10. Choices for
Database
Technologies
© 2020 Percona 10
Roll your own using commodity
building blocks (Compute, Storage ETC)
Use Database as a Service (DBaaS)
functionality

11. DBaaS Removes a lot of “Toil”
© 2020 Percona 11
Managing High
Availability
Database Patching Backups (Some)
Performance Tuning
Easy to Scale

12. Two Kind of
DBaaS
© 2020 Percona 12
THE “PLAIN” OPEN SOURCE
PRODUCT WRAPPED IN
MANAGEMENT BACKEND
“ENHANCED” (PROPRIETARY) OPEN
SOURCE COMPATIBLE SOLUTION

13. Both of them
Reduce Data
and Application
Portability
It is NOT trivial to move from Amazon RDS to Google
CloudSQL but it is even harder with Amazon Aurora
© 2020 Percona 13

14. Could We…
© 2020 Percona 14
Get Public Cloud DBaaS Like Simplicity
But as Open Source Solution

15. Bad News
We’re Not there yet
© 2020 Percona 15

16. Good News
© 2020 Percona16

17. Kubernetes
© 2020 Percona 17
“Operating System” but for Cluster,
rather individual hosts
Has a lot of Momentum
Universally Supported in Public, Private,
Hybrid Cloud

18. Kubernetes

MySQL Compatible
Strong High Availability
Open Source
Deploy Single Node if want dev database

24. Kubernetes
Users

Direct users of Kubernetes Operators
Users of the Service which happen to
run Kubernetes on Backend

25. Percona DBaaS
CLI
Experimental Solutions for those who wants to Get Open
Source DBaaS without deep Kubernetes Understanding
