Satoshi Mitani (Yahoo Japan Corporation) delivers the talk, "Immutable Database Infrastructure with Percona XtraDB Cluster", on DAY 2 of the Percona Live Open Source Database Conference 2019, 5/30, at Austin, TX.

In this session, we will discuss how we build Immutable infrastructure for databases.
Yahoo! JAPAN is the largest web portal in Japan. We have about 90 million unique browser accesses per month.

We have focused on the efficient management of many DBs.
If we need to change something, we abandon the database server entirely and re-image it.
In other words, "Immutable Infrastructure" means "Disposable".
This way, the database server keeps clean and fresh at all times.
In addition, the database does not stop during rebuilding, so it is a high availability approach.

Percona XtraDB Cluster has important functions to achieve this mechanism.

The abstract of the session includes :
- Yahoo! JAPAN introduction
- What is an "Immutable infrastructure"
- Architecture
- Why Percona XtraDB Cluster
- Disadvantages of our method
