25. What Is the
Problem with
Monopoly on
DBaaS?

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

27. DBaaS Vendor Lock-In
It may not be so painful now, but it is going to be painful in the future

29. Why Data is Special
Moving Data is Expensive. Moving Lots of Data is Very
Expensive

33. • 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

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

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

38. Can We Build
DBaaS on
Kubernetes?
